[Bug fortran/45170] [F2003] allocatable character lengths
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45170 --- Comment #26 from Tobias Burnus burnus at gcc dot gnu.org 2011-08-29 06:47:41 UTC --- (In reply to comment #24) Your code in comment #14 is (I believe) invalid, and gfortran is issuing the correct error message. I get: Error: Variable 'length' cannot appear in the expression at (1) However, I believe that allocate(character(len=length)::string) is valid. One has (F2008): R626 allocate-stmt is ALLOCATE ( [ type-spec :: ] allocation-list [, alloc-opt-list ] ) with R402 type-spec is intrinsic-type-spec or derived-type-spec with R404 intrinsic-type-spec is [...] or CHARACTER [ char-selector ] with R420 char-selector is length-selector [or ...] with R421 length-selector is ( [ LEN = ] type-param-value ) [or ...] Thus, I do not see any syntax problems; I also couldn't find any constraint or other reason which renders the code in comment #14 invalid.

[Bug tree-optimization/50204] [4.5/4.6/4.7 Regression] Missed fully redundant load found in crafty (SPEC 2k)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50204 --- Comment #3 from Richard Guenther rguenth at gcc dot gnu.org 2011-08-29 07:29:57 UTC --- The loop over PHI args is a little hard to follow, but yeah, that's how it should work. Eventually we can put this in with a new --param telling the maximum number of PHI args to consider (and defaulting it to two). I'd probably keep the n == 1 handling in the main function separately instead of trying to handle it via the loop. Then I'd pre-seed the first arg which should make the loop a little easier to follow.

So with some cleanup (essentially peel the first iteration of the loop) the patch should be ok as-is.

So perhaps before testing for vinfo_for_stmt it should || !gimple_bb (def_stmt) || !flow_bb_inside_loop_p (loop, gimple_bb (def_stmt)) and perhaps give up in those cases too? Loop would need to be initialized, perhaps similarly to vect_recog_dot_prod_pattern? loop_vec_info loop_info = STMT_VINFO_LOOP_VINFO (vinfo_for_stmt (stmt)); struct loop *loop = LOOP_VINFO_LOOP (loop_info); ? I have no idea whether this can be invoked from slp vectorizer and what to do in that case.

Schmidt wschmidt at gcc dot gnu.org 2011-08-29 13:45:36 UTC --- Jakub, I don't see -fprofile-generate in your list of options. What Peter gave you was the link command that exposed the problem, but the error occurred when compiling chgpen.fppized.f with the options given. The original options from the build log were: /home/wschmidt/gcc/install/gcc-mainline-base/bin/gfortran -c -o chgpen.fppized.o -fprofile-generate -g -save-temps=obj -ffast-math -O3 -mveclibabi=mass -mcpu=power7 -mrecip=rsqrt -fpeel-loops -funroll-loops -ftree-vectorize -fvect-cost-model -O3 -mvsx -maltivec -mpopcntd -m64 -ftree-loop-linear chgpen.fppized.f which, after -v, I was able to whittle down to: /home/wschmidt/gcc/install/gcc-mainline-base/libexec/gcc/powerpc64-linux/4.7.0/f951 chgpen.fppized.f -g -O3 -fprofile-generate -ffast-math -funroll-loops -o chgpen.fppized.s I should have left -mcpu=power7 and -m64 on there for you; sorry about that.

[Bug target/49606] mips64: o64 Unrecognizable insn when one noreturn function calling another noreturn function
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49606 --- Comment #4 from Martin Decky martin at decky dot cz 2011-08-29 14:33:07 UTC --- (In reply to comment #3) As well as making longs 64 bits wide, -mlong64 makes pointers 64 bits wide. But you're still using a 32-bit file format. If you want an LP64 ABI, then n64 seems like a better choice. Yes, this is indeed the most reasonable solution for me. So do you actually have a system that uses this ABI (o64+mlong64)? Actually, no. I was trying to cross-compile our own OS for mips64 and the o64+mlong64 combination was the first one I have tried. The 32-bit file format might or might not be eventually a problem if the compilation works (I can imagine that it might actually work fine at least for user space binaries). But the n64 ABI seems definitively to be a better choice. If so, could you give a few more details? TBH, my instinctive reaction is that this is a missing diagnostic bug, and that we should refuse to compile -mabi=o64 -mlong64. Well, I do not insist that this bug should be fixed only by making the compilation work. Your suggestion that this combination of options is not very reasonable and should be refused is sound. Either way, the compiler should not end with an internal error.

GCC 2.95.3 for PS2 Multiplication Issue
Hi, I am seeing this issue when using the 2.95.3 compiler for EE processor. When compiling the following code: unsigned int a,b; a = ((unsigned int)4294967295 * b); the 2.95.3 compiler generates the following assembly: 8fc30014 lw $v1,20($s8) 0060102d move $v0,$v1 431823 subu $v1,$v0,$v1 afc30024 sw $v1,36($s8) Of course, the result is always 0. Is this a bug or done by design because the compiler knows that the result should be stored in a 64-bit data type? For the latter case I would expect an error message to be displayed instead. Note that if I declare a as an unsigned long (64-bit) the compiler generates the correct multiplication instruction. Is there a compiler option for 2.95.3 that can work around this issue? Thanks. Charlotte

[Bug c++/2316] g++ fails to overload on language linkage
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=2316 --- Comment #20 from Marc Glisse marc.glisse at normalesup dot org 2011-08-30 00:20:07 UTC --- Created attachment 25134 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=25134 remember linkage of a function type This is an extremely basic patch, that probably misses many things (and we'd want to have conversions between externC and regular functions not to break too much code), but it can be useful to play with (it got at least 4 examples right :-) although it ICEs (assert) on some other code...). Obviously it has to be built with --disable-bootstrap since the gcc source code is far from externC-clean, but it can also be used to help clean it ;-) Oh, and it won't build libstdc++ either, first because of functions in gthread that take pthread_cancel and then because of the __stoa helper in ext/string_conversions.h (I didn't try to go further). Function type trees apparently leave at least 2 trees unused in tree_type_non_common so I reused one (minval), but since I only want one bit, there are probably better ways to store it.
[Bug target/49987] [4.7 Regression] gcc.c-torture/compile/pr34856.c fails on powerpc-darwin9 from r176228
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49987 Pat Haugen pthaugen at gcc dot gnu.org changed: What|Removed |Added CC||pthaugen at gcc dot gnu.org --- Comment #11 from Pat Haugen pthaugen at gcc dot gnu.org 2011-08-30 01:11:37 UTC --- (In reply to comment #10) Note that while gcc.c-torture/compile/pr34856.c does not fail on powerpc64-unknown-linux-gnu, gcc.dg/pr34856.c does (see http://gcc.gnu.org/ml/gcc-testresults/2011-08/msg03221.html ). Could a user of powerpc*-linux-* try the patch at http://gcc.gnu.org/ml/gcc-patches/2011-08/msg01861.html ? Yes, the patch applied to trunk fixes the ICE on gcc.dg/pr34856.c. Note that -maltivec is required to produce the error, which gcc.c-torture/compile/pr34856.c doesn't specify so that is why it didn't fail the same way.
