+Subject: [PATCH] libstdc++-v3: Update VTV vars for libtool link commands
+ [PR99172]
+
+This fixes PR 99172
+
+Currently when GCC is configured with --enable-vtable-verify, the
+libstdc++-v3 Makefiles add "-fvtable-verify=std
+-Wl,-u_vtable_map_vars_start,-u_vtable_map_vars_end" to libtool link
+commands. The "-fvtable-verify=std" piece causes alternate versions of
+libtool (such as slibtool) to fail, unable to find "-lvtv" (GNU
+libtool just removes that piece).
+
+This patch updates the libstdc++-v3 Makefiles to not pass
+"-fvtable-verify=std" to the libtool link commands.

+Subject: [PATCH] gcov: fix TOPN streaming from shared libraries
+
+Before the change gcc did not stream correctly TOPN counters
+if counters belonged to a non-local shared object.
+
+As a result zero-section optimization generated TOPN sections
+in a form not recognizable by '__gcov_merge_topn'.
+
+The problem happens because in a case of multiple shared objects
+'__gcov_merge_topn' function is present in address space multiple
+times (once per each object).
+
+The fix is to never rely on function address and predicate on TOPN
+counter types.
+
+libgcc/ChangeLog:
+
+   PR gcov-profile/96913
+   * libgcov-driver.c (write_one_data): Avoid function pointer
+   comparison in TOP streaming decision.

+Subject: [PATCH] ipa-prop: Fix multiple-target speculation resolution
+
+Hi,
+
+as the FIXME which this patch removes states, the current code does
+not work when a call with multiple speculative targets gets resolved
+through parameter tracking during inlining - it feeds the inliner an
+edge it has already dealt with.  The patch makes the code which should
+prevent it aware of the possibility that that speculation can have
+more than one target now.
+
+Bootstrapped and tested and LTO bootstrapped on x86_64-linux.  I did not
+try profiled LTO bootstrap because it fails even without the patch (even
+without Ada, just C, C++ and Fortran, at least commit 92f0d3d03a7 does).
+OK for trunk?
+
+Thanks,
+
+Martin

+Subject: [PATCH] c: Fix bogus vector initialisation error [PR96377]
+
+One of the problems in this PR was that if we had:
+
+  vector_type1 array[] = { vector_value1 };
+
+process_init_element would only treat vector_value1 as initialising
+a vector_type1 if they had the same TYPE_MAIN_VARIANT.  This has
+several problems:
+
+(1) It gives confusing error messages if the vector types are
+incompatible.  (Tested by gcc.dg/pr96377-1.c.)
+
+(2) It means that we reject code that should be valid with
+-flax-vector-conversions.  (Tested by gcc.dg/pr96377-2.c.)
+
+(3) On arm and aarch64 targets, it means that we reject some
+initializers that mix Advanced SIMD and standard GNU vectors.
+These vectors have traditionally had different TYPE_MAIN_VARIANTs
+because they have different mangling schemes.  (Tested by
+gcc.dg/pr96377-[3-6].c.)
+
+(4) It means that we reject SVE initializers that should be valid.
+(Tested by gcc.target/aarch64/sve/gnu_vectors_[34].c.)
+
+(5) After r11-1741-g:31427b974ed7b7dd54e2 we reject:
+
+  arm_neon_type1 array[] = { k ^ arm_neon_value1 };
+
+because applying the binary operator to arm_neon_value1 strips
+the "Advanced SIMD type" attributes that were added in that patch.
+Stripping the attributes is problematic for other reasons though,
+so that still needs to be fixed separately.
+
+g++.target/aarch64/sve/gnu_vectors_[34].C already pass.

+Subject: [PATCH] ipa: fix bit CPP when combined with IPA bit CP
+
+As mentioned in the PR, let's consider the following example:
+
+int
+__attribute__((noinline))
+foo(int arg)
+{
+  if (arg == 3)
+return 1;
+  if (arg == 4)
+return 123;
+
+  __builtin_unreachable ();
+}
+
+during WPA we find all calls of the function
+(yes the call with value 5 is UBSAN):
+
+  Node: foo/0:
+param [0]: 5 [loc_time: 4, loc_size: 2, prop_time: 0, prop_size: 0]
+   3 [loc_time: 3, loc_size: 3, prop_time: 0, prop_size: 0]
+ ctxs: VARIABLE
+ Bits: value = 0x5, mask = 0x6
+
+in LTRANS we have the following VRP info:
+
+  # RANGE [3, 3] NONZERO 3
+
+when we AND masks in get_default_value we end up with 6 & 3 = 2 (0x010).
+That means the only second (least significant bit) is unknown and
+value (5 = 0x101) & ~mask gives us either 7 (0x111) or 5 (0x101).
+
+That's why if (arg_2(D) == 3) gets optimized to false.
+
+gcc/ChangeLog:
+
+   PR ipa/96482
+   * ipa-cp.c (ipcp_bits_lattice::meet_with_1): Drop value bits
+   for bits that are unknown.
+   (ipcp_bits_lattice::set_to_constant): Likewise.
+   * tree-ssa-ccp.c (get_default_value): Add sanity check that
+   IPA CP bit info has all bits set to zero in bits that

+Subject: [PATCH] strlen: Fix handle_builtin_string_cmp [PR96758]
+
+The following testcase is miscompiled, because handle_builtin_string_cmp
+sees a strncmp call with constant last argument 4, where one of the strings
+has an upper bound of 5 bytes (due to it being an array of that size) and
+the other has a known string length of 1 and the result is used only in
+equality comparison.
+It is folded into __builtin_strncmp_eq (str1, str2, 4), which is
+incorrect, because that means reading 4 bytes from both strings and
+comparing that.  When one of the strings has known strlen of 1, we want to
+compare just 2 bytes, not 4, as strncmp shouldn't compare any bytes beyond
+the null.
+So, the last argument to __builtin_strncmp_eq should be the minimum of the
+provided strncmp last argument and the known string length + 1 (assuming
+the other string has only a known upper bound due to array size).
+
+Besides that, I've noticed the code has been written with the intent to also
+support the case where we know exact string length of both strings (but not
+the string content, so we can't compute it at compile time).  In that case,
+both cstlen1 and cstlen2 are non-negative and both arysiz1 and arysiz2 are
+negative.  We wouldn't optimize that, cmpsiz would be either the strncmp
+last argument, or for strcmp the first string length, but varsiz would be
+-1 and thus cmpsiz would be never < varsiz.  The patch fixes it by using the
+correct length, in that case using the minimum of the two and for strncmp
+also the last argument.

+Subject: [PATCH] ipa-prop: Fix multiple-target speculation resolution
+
+Hi,
+
+as the FIXME which this patch removes states, the current code does
+not work when a call with multiple speculative targets gets resolved
+through parameter tracking during inlining - it feeds the inliner an
+edge it has already dealt with.  The patch makes the code which should
+prevent it aware of the possibility that that speculation can have
+more than one target now.
+
+Bootstrapped and tested and LTO bootstrapped on x86_64-linux.  I did not
+try profiled LTO bootstrap because it fails even without the patch (even
+without Ada, just C, C++ and Fortran, at least commit 92f0d3d03a7 does).
+OK for trunk?
+
+Thanks,
+
+Martin

+Subject: [PATCH] strlen: Fix handle_builtin_string_cmp [PR96758]
+
+The following testcase is miscompiled, because handle_builtin_string_cmp
+sees a strncmp call with constant last argument 4, where one of the strings
+has an upper bound of 5 bytes (due to it being an array of that size) and
+the other has a known string length of 1 and the result is used only in
+equality comparison.
+It is folded into __builtin_strncmp_eq (str1, str2, 4), which is
+incorrect, because that means reading 4 bytes from both strings and
+comparing that.  When one of the strings has known strlen of 1, we want to
+compare just 2 bytes, not 4, as strncmp shouldn't compare any bytes beyond
+the null.
+So, the last argument to __builtin_strncmp_eq should be the minimum of the
+provided strncmp last argument and the known string length + 1 (assuming
+the other string has only a known upper bound due to array size).
+
+Besides that, I've noticed the code has been written with the intent to also
+support the case where we know exact string length of both strings (but not
+the string content, so we can't compute it at compile time).  In that case,
+both cstlen1 and cstlen2 are non-negative and both arysiz1 and arysiz2 are
+negative.  We wouldn't optimize that, cmpsiz would be either the strncmp
+last argument, or for strcmp the first string length, but varsiz would be
+-1 and thus cmpsiz would be never < varsiz.  The patch fixes it by using the
+correct length, in that case using the minimum of the two and for strncmp
+also the last argument.

+Subject: [PATCH] libstdc++-v3: Update VTV vars for libtool link commands
+ [PR99172]
+
+This fixes PR 99172
+
+Currently when GCC is configured with --enable-vtable-verify, the
+libstdc++-v3 Makefiles add "-fvtable-verify=std
+-Wl,-u_vtable_map_vars_start,-u_vtable_map_vars_end" to libtool link
+commands. The "-fvtable-verify=std" piece causes alternate versions of
+libtool (such as slibtool) to fail, unable to find "-lvtv" (GNU
+libtool just removes that piece).
+
+This patch updates the libstdc++-v3 Makefiles to not pass
+"-fvtable-verify=std" to the libtool link commands.

+Subject: [PATCH] libstdc++-v3: Update VTV vars for libtool link commands
+ [PR99172]
+
+This fixes PR 99172
+
+Currently when GCC is configured with --enable-vtable-verify, the
+libstdc++-v3 Makefiles add "-fvtable-verify=std
+-Wl,-u_vtable_map_vars_start,-u_vtable_map_vars_end" to libtool link
+commands. The "-fvtable-verify=std" piece causes alternate versions of
+libtool (such as slibtool) to fail, unable to find "-lvtv" (GNU
+libtool just removes that piece).
+
+This patch updates the libstdc++-v3 Makefiles to not pass
+"-fvtable-verify=std" to the libtool link commands.

+Subject: [PATCH] gcov: fix TOPN streaming from shared libraries
+
+Before the change gcc did not stream correctly TOPN counters
+if counters belonged to a non-local shared object.
+
+As a result zero-section optimization generated TOPN sections
+in a form not recognizable by '__gcov_merge_topn'.
+
+The problem happens because in a case of multiple shared objects
+'__gcov_merge_topn' function is present in address space multiple
+times (once per each object).
+
+The fix is to never rely on function address and predicate on TOPN
+counter types.
+
+libgcc/ChangeLog:
+
+   PR gcov-profile/96913
+   * libgcov-driver.c (write_one_data): Avoid function pointer
+   comparison in TOP streaming decision.

+Subject: [PATCH] c: Fix bogus vector initialisation error [PR96377]
+
+One of the problems in this PR was that if we had:
+
+  vector_type1 array[] = { vector_value1 };
+
+process_init_element would only treat vector_value1 as initialising
+a vector_type1 if they had the same TYPE_MAIN_VARIANT.  This has
+several problems:
+
+(1) It gives confusing error messages if the vector types are
+incompatible.  (Tested by gcc.dg/pr96377-1.c.)
+
+(2) It means that we reject code that should be valid with
+-flax-vector-conversions.  (Tested by gcc.dg/pr96377-2.c.)
+
+(3) On arm and aarch64 targets, it means that we reject some
+initializers that mix Advanced SIMD and standard GNU vectors.
+These vectors have traditionally had different TYPE_MAIN_VARIANTs
+because they have different mangling schemes.  (Tested by
+gcc.dg/pr96377-[3-6].c.)
+
+(4) It means that we reject SVE initializers that should be valid.
+(Tested by gcc.target/aarch64/sve/gnu_vectors_[34].c.)
+
+(5) After r11-1741-g:31427b974ed7b7dd54e2 we reject:
+
+  arm_neon_type1 array[] = { k ^ arm_neon_value1 };
+
+because applying the binary operator to arm_neon_value1 strips
+the "Advanced SIMD type" attributes that were added in that patch.
+Stripping the attributes is problematic for other reasons though,
+so that still needs to be fixed separately.
+
+g++.target/aarch64/sve/gnu_vectors_[34].C already pass.

+Subject: [PATCH] ipa: fix bit CPP when combined with IPA bit CP
+
+As mentioned in the PR, let's consider the following example:
+
+int
+__attribute__((noinline))
+foo(int arg)
+{
+  if (arg == 3)
+return 1;
+  if (arg == 4)
+return 123;
+
+  __builtin_unreachable ();
+}
+
+during WPA we find all calls of the function
+(yes the call with value 5 is UBSAN):
+
+  Node: foo/0:
+param [0]: 5 [loc_time: 4, loc_size: 2, prop_time: 0, prop_size: 0]
+   3 [loc_time: 3, loc_size: 3, prop_time: 0, prop_size: 0]
+ ctxs: VARIABLE
+ Bits: value = 0x5, mask = 0x6
+
+in LTRANS we have the following VRP info:
+
+  # RANGE [3, 3] NONZERO 3
+
+when we AND masks in get_default_value we end up with 6 & 3 = 2 (0x010).
+That means the only second (least significant bit) is unknown and
+value (5 = 0x101) & ~mask gives us either 7 (0x111) or 5 (0x101).
+
+That's why if (arg_2(D) == 3) gets optimized to false.
+
+gcc/ChangeLog:
+
+   PR ipa/96482
+   * ipa-cp.c (ipcp_bits_lattice::meet_with_1): Drop value bits
+   for bits that are unknown.

+   * tree-ssa-ccp.c (get_default_value): Add sanity check that

+through parameter tracking during inlining - it feeds the inliner an
+edge it has already dealt with.  The patch makes the code which should
+prevent it aware of the possibility that that speculation can have
+more than one target now.
+
+Bootstrapped and tested and LTO bootstrapped on x86_64-linux.  I did not
+try profiled LTO bootstrap because it fails even without the patch (even
+without Ada, just C, C++ and Fortran, at least commit 92f0d3d03a7 does).
+OK for trunk?
+
+Thanks,

+Subject: [PATCH] gcov: fix TOPN streaming from shared libraries
+
+Before the change gcc did not stream correctly TOPN counters
+if counters belonged to a non-local shared object.
+
+As a result zero-section optimization generated TOPN sections
+in a form not recognizable by '__gcov_merge_topn'.
+
+The problem happens because in a case of multiple shared objects
+'__gcov_merge_topn' function is present in address space multiple
+times (once per each object).
+
+The fix is to never rely on function address and predicate on TOPN
+counter types.
+
+libgcc/ChangeLog:
+
+   PR gcov-profile/96913
+   * libgcov-driver.c (write_one_data): Avoid function pointer
+   comparison in TOP streaming decision.

+Subject: [PATCH] c: Fix bogus vector initialisation error [PR96377]
+
+One of the problems in this PR was that if we had:
+
+  vector_type1 array[] = { vector_value1 };
+
+process_init_element would only treat vector_value1 as initialising
+a vector_type1 if they had the same TYPE_MAIN_VARIANT.  This has
+several problems:
+
+(1) It gives confusing error messages if the vector types are
+incompatible.  (Tested by gcc.dg/pr96377-1.c.)
+
+(2) It means that we reject code that should be valid with
+-flax-vector-conversions.  (Tested by gcc.dg/pr96377-2.c.)
+
+(3) On arm and aarch64 targets, it means that we reject some
+initializers that mix Advanced SIMD and standard GNU vectors.
+These vectors have traditionally had different TYPE_MAIN_VARIANTs
+because they have different mangling schemes.  (Tested by
+gcc.dg/pr96377-[3-6].c.)
+
+(4) It means that we reject SVE initializers that should be valid.
+(Tested by gcc.target/aarch64/sve/gnu_vectors_[34].c.)
+
+(5) After r11-1741-g:31427b974ed7b7dd54e2 we reject:
+
+  arm_neon_type1 array[] = { k ^ arm_neon_value1 };
+
+because applying the binary operator to arm_neon_value1 strips
+the "Advanced SIMD type" attributes that were added in that patch.
+Stripping the attributes is problematic for other reasons though,
+so that still needs to be fixed separately.
+
+g++.target/aarch64/sve/gnu_vectors_[34].C already pass.

+Subject: [PATCH] ipa: fix bit CPP when combined with IPA bit CP
+
+As mentioned in the PR, let's consider the following example:
+
+int
+__attribute__((noinline))
+foo(int arg)
+{
+  if (arg == 3)
+return 1;
+  if (arg == 4)
+return 123;
+
+  __builtin_unreachable ();
+}
+
+during WPA we find all calls of the function
+(yes the call with value 5 is UBSAN):
+
+  Node: foo/0:
+param [0]: 5 [loc_time: 4, loc_size: 2, prop_time: 0, prop_size: 0]
+   3 [loc_time: 3, loc_size: 3, prop_time: 0, prop_size: 0]
+ ctxs: VARIABLE
+ Bits: value = 0x5, mask = 0x6
+
+in LTRANS we have the following VRP info:
+
+  # RANGE [3, 3] NONZERO 3
+
+when we AND masks in get_default_value we end up with 6 & 3 = 2 (0x010).
+That means the only second (least significant bit) is unknown and
+value (5 = 0x101) & ~mask gives us either 7 (0x111) or 5 (0x101).
+
+That's why if (arg_2(D) == 3) gets optimized to false.
+
+gcc/ChangeLog:
+
+   PR ipa/96482
+   * ipa-cp.c (ipcp_bits_lattice::meet_with_1): Drop value bits
+   for bits that are unknown.
+   (ipcp_bits_lattice::set_to_constant): Likewise.
+   * tree-ssa-ccp.c (get_default_value): Add sanity check that
+   IPA CP bit info has all bits set to zero in bits that
+   are unknown.

+Subject: [PATCH] gcov: fix TOPN streaming from shared libraries
+
+Before the change gcc did not stream correctly TOPN counters
+if counters belonged to a non-local shared object.
+
+As a result zero-section optimization generated TOPN sections
+in a form not recognizable by '__gcov_merge_topn'.
+
+The problem happens because in a case of multiple shared objects
+'__gcov_merge_topn' function is present in address space multiple
+times (once per each object).
+
+The fix is to never rely on function address and predicate on TOPN
+counter types.
+
+libgcc/ChangeLog:
+
+   PR gcov-profile/96913
+   * libgcov-driver.c (write_one_data): Avoid function pointer
+   comparison in TOP streaming decision.

+Subject: [PATCH] ipa-prop: Fix multiple-target speculation resolution
+
+Hi,
+
+as the FIXME which this patch removes states, the current code does
+not work when a call with multiple speculative targets gets resolved
+through parameter tracking during inlining - it feeds the inliner an
+edge it has already dealt with.  The patch makes the code which should
+prevent it aware of the possibility that that speculation can have
+more than one target now.
+
+Bootstrapped and tested and LTO bootstrapped on x86_64-linux.  I did not
+try profiled LTO bootstrap because it fails even without the patch (even
+without Ada, just C, C++ and Fortran, at least commit 92f0d3d03a7 does).
+OK for trunk?
+
+Thanks,
+
+Martin

+Subject: [PATCH] strlen: Fix handle_builtin_string_cmp [PR96758]
+
+The following testcase is miscompiled, because handle_builtin_string_cmp
+sees a strncmp call with constant last argument 4, where one of the strings
+has an upper bound of 5 bytes (due to it being an array of that size) and
+the other has a known string length of 1 and the result is used only in
+equality comparison.
+It is folded into __builtin_strncmp_eq (str1, str2, 4), which is
+incorrect, because that means reading 4 bytes from both strings and
+comparing that.  When one of the strings has known strlen of 1, we want to
+compare just 2 bytes, not 4, as strncmp shouldn't compare any bytes beyond
+the null.
+So, the last argument to __builtin_strncmp_eq should be the minimum of the
+provided strncmp last argument and the known string length + 1 (assuming
+the other string has only a known upper bound due to array size).
+
+Besides that, I've noticed the code has been written with the intent to also
+support the case where we know exact string length of both strings (but not
+the string content, so we can't compute it at compile time).  In that case,
+both cstlen1 and cstlen2 are non-negative and both arysiz1 and arysiz2 are
+negative.  We wouldn't optimize that, cmpsiz would be either the strncmp
+last argument, or for strcmp the first string length, but varsiz would be
+-1 and thus cmpsiz would be never < varsiz.  The patch fixes it by using the
+correct length, in that case using the minimum of the two and for strncmp
+also the last argument.

+Subject: [PATCH] c: Fix bogus vector initialisation error [PR96377]
+
+One of the problems in this PR was that if we had:
+
+  vector_type1 array[] = { vector_value1 };
+
+process_init_element would only treat vector_value1 as initialising
+a vector_type1 if they had the same TYPE_MAIN_VARIANT.  This has
+several problems:
+
+(1) It gives confusing error messages if the vector types are
+incompatible.  (Tested by gcc.dg/pr96377-1.c.)
+
+(2) It means that we reject code that should be valid with
+-flax-vector-conversions.  (Tested by gcc.dg/pr96377-2.c.)
+
+(3) On arm and aarch64 targets, it means that we reject some
+initializers that mix Advanced SIMD and standard GNU vectors.
+These vectors have traditionally had different TYPE_MAIN_VARIANTs
+because they have different mangling schemes.  (Tested by
+gcc.dg/pr96377-[3-6].c.)
+
+(4) It means that we reject SVE initializers that should be valid.
+(Tested by gcc.target/aarch64/sve/gnu_vectors_[34].c.)
+
+(5) After r11-1741-g:31427b974ed7b7dd54e2 we reject:
+
+  arm_neon_type1 array[] = { k ^ arm_neon_value1 };
+
+because applying the binary operator to arm_neon_value1 strips
+the "Advanced SIMD type" attributes that were added in that patch.
+Stripping the attributes is problematic for other reasons though,
+so that still needs to be fixed separately.
+
+g++.target/aarch64/sve/gnu_vectors_[34].C already pass.

+Subject: [PATCH] ipa: fix bit CPP when combined with IPA bit CP
+
+As mentioned in the PR, let's consider the following example:
+
+int
+__attribute__((noinline))
+foo(int arg)
+{
+  if (arg == 3)
+return 1;
+  if (arg == 4)
+return 123;
+
+  __builtin_unreachable ();
+}
+
+during WPA we find all calls of the function
+(yes the call with value 5 is UBSAN):
+
+  Node: foo/0:
+param [0]: 5 [loc_time: 4, loc_size: 2, prop_time: 0, prop_size: 0]
+   3 [loc_time: 3, loc_size: 3, prop_time: 0, prop_size: 0]
+ ctxs: VARIABLE
+ Bits: value = 0x5, mask = 0x6
+
+in LTRANS we have the following VRP info:
+
+  # RANGE [3, 3] NONZERO 3
+
+when we AND masks in get_default_value we end up with 6 & 3 = 2 (0x010).
+That means the only second (least significant bit) is unknown and
+value (5 = 0x101) & ~mask gives us either 7 (0x111) or 5 (0x101).
+
+That's why if (arg_2(D) == 3) gets optimized to false.
+
+gcc/ChangeLog:
+
+   PR ipa/96482
+   * ipa-cp.c (ipcp_bits_lattice::meet_with_1): Drop value bits
+   for bits that are unknown.

+Subject: [PATCH] libstdc++-v3: Update VTV vars for libtool link commands
+ [PR99172]
+
+This fixes PR 99172
+
+Currently when GCC is configured with --enable-vtable-verify, the
+libstdc++-v3 Makefiles add "-fvtable-verify=std
+-Wl,-u_vtable_map_vars_start,-u_vtable_map_vars_end" to libtool link
+commands. The "-fvtable-verify=std" piece causes alternate versions of
+libtool (such as slibtool) to fail, unable to find "-lvtv" (GNU
+libtool just removes that piece).
+
+This patch updates the libstdc++-v3 Makefiles to not pass
+"-fvtable-verify=std" to the libtool link commands.

+Subject: [PATCH] ipa: fix ICE in get_default_value
+
+The patch aligns code with ipcp_bits_lattice::set_to_constant
+where we properly mask m_value with m_mask. The same should
+be done here.
+
+gcc/ChangeLog:
+
+   PR ipa/96482
+   * ipa-cp.c (ipcp_bits_lattice::meet_with_1): Mask m_value
+   with m_mask.

+   PR ipa/96482
+   * gcc.dg/ipa/pr96482-2.c: New test.

+Subject: [PATCH] gcov: fix TOPN streaming from shared libraries
+
+Before the change gcc did not stream correctly TOPN counters
+if counters belonged to a non-local shared object.
+
+As a result zero-section optimization generated TOPN sections
+in a form not recognizable by '__gcov_merge_topn'.
+
+The problem happens because in a case of multiple shared objects
+'__gcov_merge_topn' function is present in address space multiple
+times (once per each object).
+
+The fix is to never rely on function address and predicate on TOPN
+counter types.
+
+libgcc/ChangeLog:
+
+   PR gcov-profile/96913
+   * libgcov-driver.c (write_one_data): Avoid function pointer
+   comparison in TOP streaming decision.

+Subject: [PATCH] ipa-prop: Fix multiple-target speculation resolution
+
+Hi,
+
+as the FIXME which this patch removes states, the current code does
+not work when a call with multiple speculative targets gets resolved
+through parameter tracking during inlining - it feeds the inliner an
+edge it has already dealt with.  The patch makes the code which should
+prevent it aware of the possibility that that speculation can have
+more than one target now.
+
+Bootstrapped and tested and LTO bootstrapped on x86_64-linux.  I did not
+try profiled LTO bootstrap because it fails even without the patch (even
+without Ada, just C, C++ and Fortran, at least commit 92f0d3d03a7 does).
+OK for trunk?
+
+Thanks,
+
+Martin

+Subject: [PATCH] strlen: Fix handle_builtin_string_cmp [PR96758]
+
+The following testcase is miscompiled, because handle_builtin_string_cmp
+sees a strncmp call with constant last argument 4, where one of the strings
+has an upper bound of 5 bytes (due to it being an array of that size) and
+the other has a known string length of 1 and the result is used only in
+equality comparison.
+It is folded into __builtin_strncmp_eq (str1, str2, 4), which is
+incorrect, because that means reading 4 bytes from both strings and
+comparing that.  When one of the strings has known strlen of 1, we want to
+compare just 2 bytes, not 4, as strncmp shouldn't compare any bytes beyond
+the null.
+So, the last argument to __builtin_strncmp_eq should be the minimum of the
+provided strncmp last argument and the known string length + 1 (assuming
+the other string has only a known upper bound due to array size).
+
+Besides that, I've noticed the code has been written with the intent to also
+support the case where we know exact string length of both strings (but not
+the string content, so we can't compute it at compile time).  In that case,
+both cstlen1 and cstlen2 are non-negative and both arysiz1 and arysiz2 are
+negative.  We wouldn't optimize that, cmpsiz would be either the strncmp
+last argument, or for strcmp the first string length, but varsiz would be
+-1 and thus cmpsiz would be never < varsiz.  The patch fixes it by using the
+correct length, in that case using the minimum of the two and for strncmp
+also the last argument.

+Subject: [PATCH] c: Fix bogus vector initialisation error [PR96377]
+
+One of the problems in this PR was that if we had:
+
+  vector_type1 array[] = { vector_value1 };
+
+process_init_element would only treat vector_value1 as initialising
+a vector_type1 if they had the same TYPE_MAIN_VARIANT.  This has
+several problems:
+
+(1) It gives confusing error messages if the vector types are
+incompatible.  (Tested by gcc.dg/pr96377-1.c.)
+
+(2) It means that we reject code that should be valid with
+-flax-vector-conversions.  (Tested by gcc.dg/pr96377-2.c.)
+
+(3) On arm and aarch64 targets, it means that we reject some
+initializers that mix Advanced SIMD and standard GNU vectors.
+These vectors have traditionally had different TYPE_MAIN_VARIANTs
+because they have different mangling schemes.  (Tested by
+gcc.dg/pr96377-[3-6].c.)
+
+(4) It means that we reject SVE initializers that should be valid.
+(Tested by gcc.target/aarch64/sve/gnu_vectors_[34].c.)
+
+(5) After r11-1741-g:31427b974ed7b7dd54e2 we reject:
+
+  arm_neon_type1 array[] = { k ^ arm_neon_value1 };
+
+because applying the binary operator to arm_neon_value1 strips
+the "Advanced SIMD type" attributes that were added in that patch.
+Stripping the attributes is problematic for other reasons though,
+so that still needs to be fixed separately.
+
+g++.target/aarch64/sve/gnu_vectors_[34].C already pass.

+Subject: [PATCH] ipa: fix bit CPP when combined with IPA bit CP
+
+As mentioned in the PR, let's consider the following example:
+
+int
+__attribute__((noinline))
+foo(int arg)
+{
+  if (arg == 3)
+return 1;
+  if (arg == 4)
+return 123;
+
+  __builtin_unreachable ();
+}
+
+during WPA we find all calls of the function
+(yes the call with value 5 is UBSAN):
+
+  Node: foo/0:
+param [0]: 5 [loc_time: 4, loc_size: 2, prop_time: 0, prop_size: 0]
+   3 [loc_time: 3, loc_size: 3, prop_time: 0, prop_size: 0]
+ ctxs: VARIABLE
+ Bits: value = 0x5, mask = 0x6
+
+in LTRANS we have the following VRP info:
+
+  # RANGE [3, 3] NONZERO 3
+
+when we AND masks in get_default_value we end up with 6 & 3 = 2 (0x010).
+That means the only second (least significant bit) is unknown and
+value (5 = 0x101) & ~mask gives us either 7 (0x111) or 5 (0x101).
+
+That's why if (arg_2(D) == 3) gets optimized to false.
+
+gcc/ChangeLog:
+
+   PR ipa/96482
+   * ipa-cp.c (ipcp_bits_lattice::meet_with_1): Drop value bits
+   for bits that are unknown.
+   (ipcp_bits_lattice::set_to_constant): Likewise.
+   * tree-ssa-ccp.c (get_default_value): Add sanity check that
+   IPA CP bit info has all bits set to zero in bits that

+Subject: [PATCH] libstdc++-v3: Update VTV vars for libtool link commands
+ [PR99172]
+
+This fixes PR 99172
+
+Currently when GCC is configured with --enable-vtable-verify, the
+libstdc++-v3 Makefiles add "-fvtable-verify=std
+-Wl,-u_vtable_map_vars_start,-u_vtable_map_vars_end" to libtool link
+commands. The "-fvtable-verify=std" piece causes alternate versions of
+libtool (such as slibtool) to fail, unable to find "-lvtv" (GNU
+libtool just removes that piece).
+
+This patch updates the libstdc++-v3 Makefiles to not pass
+"-fvtable-verify=std" to the libtool link commands.

+Subject: [PATCH] ipa: fix ICE in get_default_value
+
+The patch aligns code with ipcp_bits_lattice::set_to_constant
+where we properly mask m_value with m_mask. The same should
+be done here.
+
+gcc/ChangeLog:
+
+   PR ipa/96482
+   * ipa-cp.c (ipcp_bits_lattice::meet_with_1): Mask m_value
+   with m_mask.
+
+gcc/testsuite/ChangeLog:
+
+   PR ipa/96482
+   * gcc.dg/ipa/pr96482-2.c: New test.
