[Bug fortran/45489] Default initialization of derived-type function result missing
--- Comment #3 from burnus at gcc dot gnu dot org 2010-09-02 07:31 ---
(In reply to comment #2)
It seems to work if one adds
if (!a-referenced sym-value)
gfc_set_sym_referenced (sym);
As gfortran does not use a static initializer via sym-value but an assignment,
this check does not work.
The following patch should work:

[Bug libstdc++/40974] [4.3/4.4/4.5/4.6 Regression] cannot build gcc-4.4.1: fenv_t has not been declared
--- Comment #44 from boris at kolpackov dot net 2010-09-02 08:23 --- I just ran into the same issue building (native) mingw32 GCC 4.5.1 using a x86-64 to mingw32 cross compiler. Adding -nostdinc++ to PCHFLAGS fixed this for me as well. I also would like to point out that when building in this configuration the target libraries (libgcc, libstc++) are built using the cross-compiler. Since these libraries are internal to GCC (and can theoretically track the GCC version), I think it is reasonable to expect that the cross and native compilers are the exact same version of GCC. Using different versions in this setup is just asking for trouble. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40974
[Bug c++/45462] Bad optimization in -O3 sometimes
--- Comment #13 from rguenth at gcc dot gnu dot org 2010-09-02 09:07

(In reply to comment #11)

typedef my_unaligned_aliasing_uint32 uint32
__attribute__((aligned(1),may_alias));
inline __attribute__((__always_inline__)) uint32 READ_UINT32(const void
*ptr)
{
return *(const my_unaligned_aliasing_uint32 *)ptr;
}
It does not:
READ_UINT32:
j $31
lw $2,0($4)
The aligned attribute is ignored there I think.
It is if the target is STRICT_ALIGNMENT (which of course is a bug, but
well ... and I happen to have a fix as well)
memcpy produces:
lbu $2,3($4)
lbu $6,0($4)
lbu $5,1($4)
lbu $3,2($4)
addiu $sp,$sp,-16
sb $6,0($sp)
sb $5,1($sp)
sb $3,2($sp)
sb $2,3($sp)
lw $2,0($sp)
j $31
addiu $sp,$sp,16
Which is bad and could be improved by using lwl/lwr. I will file a bug about
that.

[Bug lto/45496] New: Static members of templates cause LTO to omit required code
Compiling and linking these two files together should succeed.
/* BEGIN 1.cpp */
int callme();
int main(int argc, char** argv) { return callme(); }
/* END 1.cpp */
/* BEGIN 2.cpp */
templatetypename T struct holder { static int var; };
templatetypename T int holderT::var = 0;
int callme() { return holdervoid::var; }
/* END 2.cpp */
Indeed, compiling and linking them together without LTO succeeds. However, with
LTO, linking fails because of an undefined reference:
$ g++-4.5 -flto 1.cpp 2.cpp
/tmp/ccORg22M.lto.o: In function `main':

[Bug fortran/45495] ICE: For character function with length specifier dependent on non-present arg
--- Comment #2 from burnus at gcc dot gnu dot org 2010-09-02 11:32 --- Confirm: It compiles with g95 and NAG f95, but ICEs with gfortran (4.1 to 4.6) and a couple of other compilers. My feeling is that the program is invalid - at least in case the actual argument is not present. The program compiles (and runs) if one passes an actual argument - thus the problem only occurs very late during folding. The best probably would be to add a warning (default on?) and some conditions around the expression such that it remains valid for folding even if the argument is not present. Due to the complexity of fixing it for invalid programs - without having a chance to print an error message at compile time, I have reduced the priority to minor. Valgrind shows: ==5725== Invalid read of size 8 ==5725==at 0x896636: get_frame_type (tree-nested.c:223) ==5725==by 0x896BFF: get_chain_decl (tree-nested.c:330) ==5725==by 0x899ED5: get_nonlocal_debug_decl (tree-nested.c:842) ==5725==by 0x89A7C1: convert_nonlocal_reference_op (tree-nested.c:920) ==5725==by 0x9D0B66: walk_tree_1 (tree.c:10174) ==5725==by 0x70F96B: walk_gimple_op (gimple.c:1356) -- burnus at gcc dot gnu dot org changed: What|Removed |Added Severity|critical|minor Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Keywords||ice-on-invalid-code Known to fail||4.2.1 4.1.2 4.3.4 4.4.0 ||4.5.1 4.6.0 Last reconfirmed|-00-00 00:00:00 |2010-09-02 11:32:28 date|| Summary|ICE: For character function |ICE: For character function |with length specifier |with length specifier |dependent on non-present|dependent on non-present arg |arg.| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45495

[Bug rtl-optimization/45498] New: Optimisations fail above arbitrary level of complexity
Slightly increasing the complexity of a function can disproportionately increase the size and runtime of the generated code. This appears to be due to the optimisers giving up on code blocks above a certain abstract size, and is particularly severe on PPC and ARM, but is observable on ia32 and amd64 as well. This is a general problem which affects any large function, and has done since at least gcc3 days - I first encountered it when trying to use Altivec intrinsics. In some cases manually moving a function call *out* of a loop results in 4x the runtime, which is the opposite of normal expectations. Attached is an example which demonstrates poor code generated after a long series of inlining and dead code elimination stages. Demonstration is on PPC32, but the same example suffices for ARMv7-A as well. An amd64 target produces reasonable code for this example, but a fairly small complexity increase causes a similar collapse. The output is two functions, one generated from the tower of inlining, and the other (with a manual_ prefix) after the same optimisations were performed manually. The quality of the latter is clearly better than the former, which contains the following sequence in the inner loop: fmuls 0,12,0 stw 4,32(1) stw 3,16(1) stw 3,20(1) stfs 0,8(1) lwz 4,8(1) stw 4,24(1) li 4,0 stw 4,36(1) lfs 0,24(1) fmadds 0,9,0,10 All of the stw's in the above fragment are dead, except the stw 4,24(1) which merely shuffles the value from f0 through two memory locations and back to f0. The li 4,0 also demonstrates very poor register allocation, since r4 already contains zero before this fragment. In the manual variant, the fmuls is immediately followed by the fmadds. The same source file run through Clang on amd64 produces virtually identical output for the two versions. -- Summary: Optimisations fail above arbitrary level of complexity Product: gcc Version: 4.4.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: rtl-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jonathan dot morton at movial dot com GCC build triplet: powerpc-linux-gnu GCC host triplet: powerpc-linux-gnu GCC target triplet: powerpc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45498
