[Bug target/24475] gcc.dg/tls/pr24428.c execution test and gcc.dg/tls/pr24428-2.c execution test fail on IA32
--- Comment #6 from uros at kss-loka dot si 2005-11-15 08:13 ---
Perhaps a runtime check should be added to target-supports.exp
( check_effective_target_tls-runtime perhaps) that would check if the system is
capable of running tls enabled binaries. Alternatively, my proposed patch
(http://gcc.gnu.org/ml/gcc-patches/2005-11/msg00963.html) could try to run the
tls testcase, instead of just compiling it.
However, addind { dg-require-effective-target tls-runtime }, runtime tests will
also be skipped on the system that is otherwise able to compile testcases.
The job of compiler is IMO to compile sources correctly, and the purpose of
runtime test is to check if the system is able to run testcases. Runtime
failure, reported here, just says that the tested system is not able to run the
testcase and that the system should be upgraded/fixed.

--- Comment #1 from aj at gcc dot gnu dot org 2005-11-15 08:14 --- Jim Wilson commented in http://gcc.gnu.org/ml/gcc/2005-11/msg00619.html: Just grepping for "_STRING_INCLUDED" it is easy to see the input rule in inclhack.def that defines this transformation, and the output rule in fixincl.x that actually does the transformation. This seems to be a generic problem. Anything using the "replace = " type rule is ending up with a missing newline on the last line. Looking at gcc-3.3.4, I see that the trailing newline is there in the fixincl.x file, but it isn't there in mainline. Offhand, I don't know what changed here. It could be that autogen changed, it could be that something in fixincluded changed, or it could even be that someone checked in the result of a broken autogen. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24870

[Bug c++/24849] [gomp] ICE in expand_expr_real_1
--- Comment #2 from jakub at gcc dot gnu dot org 2005-11-15 08:59 --- The problem here is a mismatch between determine_parallel_type in gimplify.c and omp-low.c. During gimplification, it is not considered to be a combined parallel loop, because OMP_PARALLEL's body contains a DECL_EXPR (for m variable) before OMP_FOR. But during omp lowering, that DECL_EXPR is already gone and therefore the loop is handled as a combined loop. But there are statements before the FOR_STMT inside of OMP_FOR, and those are moved into a wrong context when doing a parallel loop. Maybe we should ignore (some?) DECL_EXPRs in determine_parallel_type, maybe we need to note the combined parallel status in OMP_PARALLEL's flags. -- jakub at gcc dot gnu dot org changed: What|Removed |Added CC||rth at gcc dot gnu dot org, ||dnovillo at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24849

[Bug rtl-optimization/24823] [4.1 Regression] ICE
--- Comment #5 from krebbel at gcc dot gnu dot org 2005-11-15 16:47 ---
The only difference my patch brought is different behaviour
of mark_set_1 if it is called under wrong! conditions. Will
say that only in case somebody calls mark_set_1 clobbering a reg which
is live afterwards - we would usually consider this a bug.
But because the different liveness analyzers used by global
alloc and flow we may have such a situation for uninitialized
quantities. But this didn't happen here. So the question is why
somebody calls mark_set_1 to clobber a reg which seem to be
needed afterwards?
The problematic mark_set_1 call comes from flow.c:1876 where
mark_set_1 is used to end the live ranges of all call clobbered
registers by pretending to have found a clobber for them. For
the testcase this is done for a 3dnow register xmm1 although
that register is live afterwards (at the end of the bb).
Due to my patch no REG_DEAD note is emitted because it is
assumed that xmm1 holds the value of an uninitialized variable.
So why xmm1 is live at bb end? I think the problem here is that
mark_used_regs doesn't handle PARALLELs as destination of a SET
properly. It shouldn't mark the destination reg USED by the call.
For single SETs this works well (flow.c:3972) but for a non BLKmode
PARALLEL we fall through to line 4099 which calls mark_used_regs
recursively for all parts of the PARALLEL and therefore lets the regs
in the following insn be live before that insn up to the entry bb:
(call_insn:HI 361 360 362 32 (set (parallel:DC [
(expr_list:REG_DEP_TRUE (reg:DF 21 xmm0)
(const_int 0 [0x0]))
(expr_list:REG_DEP_TRUE (reg:DF 22 xmm1)
(const_int 8 [0x8]))
])
(call (mem:QI (symbol_ref:DI ("zlatm2_") [flags 0x41]
) [0 S1 A8])
Btw. it is completely unclear to me what this kind of destination
shall mean. Any explanations are welcome.

[Bug ada/22533] [4.1 regression] Ada ICE during bootstrap on many platforms
--- Comment #28 from uweigand at gcc dot gnu dot org 2005-11-15 18:31 --- Just one additional comment: the patch from comment #10 was rejected, maybe because it required changes to the core gimplifier. However, I've tested just the Ada front-end pieces from that patch, and this *already* fixed the problem for me. The reason appears to be that -in general- occurrences of ADDR_EXPR (CONSTRUCTOR) do not constitute a problem. The problem only comes when such constructs occur in turn as part of another (outer) CONSTRUCTOR. The middle-end never generates that case, only the Ada front-end does -- thus it suffices to fix those cases in the Ada front-end itself. So I guess it would be possible right now to fix the bootstrap issue by a pure front-end patch. (This doesn't address the more general question of whether or not the gimplifier has a bug that can be exposed by other front-ends too, of course ...) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22533

--- Comment #14 from mmitchel at gcc dot gnu dot org 2005-11-15 19:23 --- There is nothing wrong with the code in Comment #1; __imag__ is an lvalue-yielding operator. If, for some reason, we wanted to make __imag__ yield an rvalue, then this code would be rejected with an error; under no circumstances should it yield a warning about the complex value being uninitialized upon initialization of its imaginary component. It would be reasonable to warn about a subsequent use of the complex value, as the real part remains uninitialized. Andrew's comments about the fact that __complex__ is a scalar are irrelevant. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23497

Similarly for the arm eabi unwind info. Note that this may be a good solution for ia64, but it really is not for ARM. ARM unwind information is only usable by the debugger in very few cases, because everything interesting is handled by a personality routine; it's only if you use one of the standard table formats (which GCC does) that the debugger can decode it. But we do still emit .debug_frame for ARM, and the debugger does use that. So presumably that's plenty to use DW_OP_call_frame_cfa. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=2

[Bug target/24856] call to setlocale doesn't return expected value
--- Comment #15 from tedoc2000 at gmail dot com 2005-11-15 21:27 --- Okay so it wasn't the --with-local-prefix. It was the fact that I used --prefix=/opt/OPSWbuildtools/1.0.1. If I use a directory that doesn't already exist then I get my desired results. So that makes us ask. "Well what do you have in /opt/OPSWbuildtools/1.0.1?" I will attach a list of the contents. Basically it is an install of libiconv-1.9.1 gawk-3.1.4 coreutils-5.1.2 make-3.8.0 The most suspicious of the above(IMHO) is the libiconv.. But even though I am specifying --with-iconv-prefix=/opt/OPSWbuildtools/1.0.1, I don't see that being used when linking in gcc/ I just see -liconv. The only other visible difference I see is when collect2 runs I see a -L/opt/OPSWbuildtools/1.0.1/lib. But as my test program doesn't use iconv in anyway I don't see how that could make a difference. I'm testing to see if just the existance of the directory but without contents also causes the same problem. Back when I have definitive results. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24856

I think we should make this based on one part being uninitialized as we are currently because that is just crazy otherwise. Again this is just like: a=(a&0x)|(b&0x000) which is what the gimplifier does currently where b is the real part of a is the full part. There is no difference between that and doing __imag___ a = b; I don't see why the warning here is bogus as it is loading by parts the a and is uninitialized when comming in. Scaler types are defined this way so you can do optimizations like this. __imag__ a = b is really defined as a = COMPLEX, b> which is the same as doing what I did for an integer type. I don't understand why there is a reluntant to fixing libstdc++ so that you get better optimizable code. I would not doubt this could cause wrong code due to how libstdc++ does the initialization of complex. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23497

Here is the current patch so for libstdc++ (I did not test it yet):

This also makes more and more optimization opertinutes for complex in
libstdc++. This also makes this code a little more readible.

Nobody wants to see a warning about an uninitialized variable use on: __complex__ double t; __imag__ t = 0.0; __real__ t = 0.0; If Andrew doesn't like the fact that __imag__ is an lvalue, then Andrew should complain to the C front-end maintainers. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23497
[Bug libstdc++/21251] Placement into shared memory
--- Comment #9 from et at ihear dot com 2005-11-15 22:10 --- This cripples virtual inheritance for fine-grain parallel processing. There should at least be a compiler option for process-independent referencing, because admittedly, this would slow down dereferencing. Or maybe a operator new placement variant that specifies process-independent referencing. I can see that either way, it would cause major ripple effects. Maybe that's why I don't see any action on this item since May. I am making this comment because I think it is a very important enhancement to make as soon as possible, as processors go multi-core. I have also read that the other signicifant c++ compiler uses process independent referencing. -- et at ihear dot com changed: What|Removed |Added CC||et at ihear dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21251

--- Comment #10 from pcarlini at suse dot de 2005-11-15 22:38 --- To be sure we don't confuse two issues here (see also my #7), all the containers are already able to use shared memory allocators such as libmm: http://www.ossp.org/pkg/lib/mm/ (via a very lightweight wrapper). This is even true for basic_string if config with --fully-dynamic-string, and certainly for ext/vstring (or basic_string in v7-branch). Another thing is the first issue in this PR, i.e., using a placement new in shared memory, the last comment #9 if I understand well, things like that. Maybe it would be better separate the two issues in separate PRs. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21251
