[Bug target/27537] XMM alignment fault when compiling for i386 with -Os
--- Comment #11 from agner at agner dot org 2006-08-23 08:04 --- This problem wouldn't have happened if the ABI had been better maintained. Somebody decides to change the calling convention without properly documenting the change, and somebody else makes another change that is incompatible because the alignment requirement has never made it into the ABI documents. Let me help you making a decision on this issue by summarizing the pro's and con's of 16-bytes stack alignment in 32-bit x86 Linux/BSD. Advantages of enforcing 16-bytes stack alignment: - 1. The use of XMM code is becoming more common now that all new computers have support for the SSE2 or higher instructions set. The necessary alignment of XMM variables can be implemented more efficiently when the stack is aligned. 2. Variables of type double (double precision floating point) are accessed more efficiently when aligned by 8. This is easily achieved when the stack is aligned. 3. Function parameters of type double will automatically get the optimal alignment, unless the parameter is preceded by an odd number of smaller parameters (including any 'this' pointer and return pointer). This means that more than 50% of function parameters of type double will be optimally aligned, versus 50% without stack alignment. The C/C++ programmer will be able to ensure optimal alignment by manipulating the order of function parameters. 4. Functions that need to align local variables can do so without using EBP as stack frame. This frees EBP for other purposes. General purpose registers is a scarce resource in 32-bit mode. 5. 16-bytes stack alignment is officially enforced in Intel-based Mac OS X. It is desirable to have identical ABI's for Linux, BSD and Mac. This makes it possible to use the same compilers and the same function libraries for all three platforms (except for the object file format, which can be converted). 6. The stack alignment requires no extra instructions in leaf functions, which are more likely to contain the critical innermost loop than non-leaf functions. 7. The stack alignment requires no extra instructions in a non-leaf function if the function adjusts the stack pointer anyway for the sake of allocating local storage. 8. Stack alignment is already implemented in Gcc and existing code relies on it. Disadvantages of enforcing 16-bytes stack alignment: 1. A non-leaf function without any stack space allocated for local storage needs one or two extra instructions for conforming to the stack alignment requirement. 2. The alignment requirement results in unused space in the stack. This takes up to 12 bytes of extra space in the data cache for each function calling level except the innermost. Assuming that only the innermost three function levels matter in terms of speed, and that the number of unused bytes is 8 on average for all but the innermost function, the total amount of space wasted in the data cache is 16 bytes. 3. The Intel compiler does not enforce stack alignment. However, the Intel people are ready to change this as soon as you Gnu people make a decision on this issue. I have contact with the Intel people about this issue. 4. Stack alignment is not enforced in 32-bit Windows. Compatibility with the Windows ABI might be desirable. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27537
[Bug tree-optimization/28807] [4.2 Regression] wrong code with may_alias and structs
--- Comment #5 from pinskia at gcc dot gnu dot org 2006-08-23 08:06 ---
(In reply to comment #4)
This is a hard nut to crack, my *guess* is that if you just check the
alias set of the type of the access, we are going to end up claiming any
access to a structure containing a char variable is aliased.
You are correct as we regress with the following testcase:
struct a
{
char a1;
};
int *aa;
void g(int *a)
{
aa = a;
*a = 2;
}
int t(int i, struct a *b)
{
g(i);
b-a1 = 1;
i = 2;
if (b-a1 != 1)
link_failure ();
}
int main(void)
{
struct a b;
t(1, b);
return 0;
}

[Bug fortran/28813] gfortran.dg/direct_io_6.f90 can exhaust system disk space
--- Comment #2 from howarth at nitro dot med dot uc dot edu 2006-08-23 08:28 --- Jerry, Yes. I filed the bug report after my wife lost a bunch of open word processing documents when Word crashed while the direct_io_6 test was executing in the background under MacOS X. I suspect this problem may occur with other operating systems and applications as well. This probably is the only gcc testsuite test that is certain to exhaust the available diskspace. Isn't there someway to check for available disk space within fortran? Normally when this test is executing on an idle machine, the test silently fails. However, on MacOS X at least, if you are actively using the browser or other applications, an alert comes up reporting that the disk is full. So it definitely is an issue under MacOS X. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28813

[Bug c/28821] New: Unable to build Python
There are two problems:
1.) Unsatisfied code symbol '__cxa_finalize' in load module
gcc-4.1.0 compiles __cxa_finalize into shared libs as weak symbol
(4611686018427425864| 4|FUNC |WEAK |0| .text|__cxa_finalize), gcc-4.1.1
doesn't (0| 0|FUNC |GLOB |0| UNDEF|__cxa_finalize). That's a problem
for Python because it loads modules at runtime.
To solve this problem John David Anglin suggested the following patch which
forces the linkage of __cxa_finalize into main:

--- Comment #4 from amylaar at gcc dot gnu dot org 2006-08-23 15:20 --- As far as I can see, the only reason why we can have a REG_EH_REGION note on a non-call instruction is when the instruction may trap, and we compile with -fnon-call-exceptions. (In reply to comment #3) Here is a workaround. Although it doesn't solve the issue completely, it'd be better than nothing. It prevents to insert the mode switching code after the last insn of BB when that insn has the REG_EH_REGION note. I think you can get an incorect mode this way, when the fall-thorough path is supposed to have a different mode than the abnormal edge destination. In fact, if the modes were the same, and not in conflict with the last insn of the source BB, LCM would be expected to place the mode switch into the source block or even earlier in the flow graph. I think the only sane way to handle this is not to emit any mode switching code for exception edges at the potential trapping site, and make the exception handling code assume no particular mode is present (unless the compiler can prove that an exception handler can only be reached from throwing/trapping sites that all have the same mode). It also checks if the last insn needs a mode which doesn't match with the mode given by the mode switching code in such case. If HONOR_SNANS of flag_trapping_math is active together with -fnon-call-exceptions, such problems can be expected for floating point operations. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28764

Produces the following error:

Where line 22 is the #if and the second ( is the 12th character. The problem
appears to be that the #if is parsing the line before the sizeof() is resolved
to its manifest constant. This causes the parser to treat sizeof as a term
and therefore to want a binary operator prior to the next term (in this case,
the open paren). The fix is to resolve the sizeof first. I tried creating a
#define for the sizeof() and replacing the defined value in the #if, but that
produced exactly the same error.

[Bug c/28823] sizeof not handled by pre-processor in #if statement
--- Comment #2 from gmalkin at convergedaccess dot com 2006-08-23 21:17 --- Okay, so sizeof isn't part of the pre-processor. That doesn't change the fact that the #if as written in the code SHOULD be valid (by every C spec I've looked at). Something in gcc is not doing the right thing. Don't just close the bug because I made a mistake describing it; it's still a bug! -- gmalkin at convergedaccess dot com changed: What|Removed |Added CC||gmalkin at convergedaccess ||dot com Status|RESOLVED|UNCONFIRMED Resolution|INVALID | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28823
[Bug c/28823] sizeof not handled by pre-processor in #if statement
--- Comment #3 from pinskia at gcc dot gnu dot org 2006-08-23 21:22 --- (In reply to comment #2) Okay, so sizeof isn't part of the pre-processor. That doesn't change the fact that the #if as written in the code SHOULD be valid (by every C spec I've looked at). Something in gcc is not doing the right thing. Don't just close the bug because I made a mistake describing it; it's still a bug! What spec are you reading? The preprocessor acts way before parsing/semantic anylsis happens. This is not a bug as the C preprocessor does not anything about types or any semantics of C, just themself. Even ICC rejects this code. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28823
[Bug target/28825] New: return (vector float) { a, a, b, b } generates unwanted MMX insns
X-Bugzilla-Reason: CC
+++ This bug was initially created as a clone of Bug #24073 +++
Take the following example:
#define vector __attribute__((vector_size(16)))
float a; float b;
vector float f(void) { return (vector float){ a, b, 0.0, 0.0}; }
---
Currently we get:

movaps %xmm1, %xmm0
xorl%eax, %eax

movl%eax, (%esp)
movl%edx, 4(%esp)
xorps %xmm1, %xmm1
movlhps %xmm1, %xmm0
addl$12, %esp
--
We should be able to produce:
movss _b, %xmm0
movss _a, %xmm1
shufps 60, /*[0, 3, 3, 0]*/, %xmm1, %xmm0 // _a, 0, 0, _b
shufps 201, /*[3, 0, 2, 1]*/, %xmm0, %xmm0 // _a, _b, 0, 0
This is from Nathan Begeman.

I think that following example wins the contest:

I think that following example wins the contest:
vector float f(void) { return (vector float){ a, a, b, b}; }
For this, it is a different bug. The issue with the above is that
ix86_expand_vector_init_duplicate check
for mmx_okay is bad.
Currently, we have
if (!mmx_ok !TARGET_SSE)
but I if I change it to:
if (!mmx_ok)
we get:
movss _a, %xmm0
movss _b, %xmm1
unpcklps%xmm0, %xmm0
unpcklps%xmm1, %xmm1
movlhps %xmm1, %xmm0
Which looks ok to me. That testcase should be opened into another bug as it is
obviously wrong.

--- Comment #11 from wilson at specifix dot com 2006-08-23 21:25 --- Subject: Re: [4.0/4.1/4.2 regression] in schedule_insns, at sched-rgn.c:3038 on mips tbm at gcc dot gnu dot org wrote: Any update on this, Jim? No. My life continues to be busy and complicated, making it difficult to do much gcc work. However, I did put a patch in the PR. If anyone else has time, they could try testing it. It needs a bootstrap and regression test. I think the problem is best fixed on mainline by merging in the dataflow branch, but for currently supported releases, and for the pending 4.2 release, I think the simple fix in the PR is best. So if we add this fix to the mainline now, then we need to remember to remove it when the dataflow branch goes in, or else prevent it from migrating to the dataflow branch. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27883

Honestly, there should be no other case in which the edge actually needs
to be split. It is just a shortcut rather than trying to whether we
want the beginning of the succ or the end of the pred (it figures it out

If you could attach the dump from

Without more, it's either something *very* strange in the code modula3

confused and believes it needs to create a block in a case it doesn't.

[Bug c/28831] New: Aggregate copy not elided when using a return value as a pass-by-value parameter
Bug 23372 was a missed optimization with respect to GCC 3.4. It is now fixed
when the parameter is a reference. But there is still a regression when the
parameter is the return value of another function. Testcase: (-Wall -O3
--march=i386)
struct A { int a[1000]; };
struct A f();
void g(struct A);
void h() { g(f()); }
GCC 3.3 and 3.4 first allocate the stack frame of g and then require f to
directly store its return value in the parameter location. GCC 4.0, 4.1, and
4.2 (as of 2006-08-23) use another stack location for the return value of f,
then allocate the stack frame of g, and finally copy the value to this new
frame (possibly using a byte-by-byte copy, see bug 27055). The code generated
by GCC 3.x is optimal, the one by GCC 4.x is not.
GCC 3.4:
movl%esp, %eax
subl$12, %esp
pushl %eax
callf

[Bug c++/28766] compound literal expression vs templates
--- Comment #3 from pinskia at gcc dot gnu dot org 2006-08-24 03:29 ---
(In reply to comment #2)
It doesn't seem to matter for me whether the function is a template or
not. Which version did you use to get to that statement?
4.2.0 20060821 works without the template in that the following works:
struct A { int i; };
void foo()
{
((struct A) { 0 }).i += 1;
}

[Bug c++/28827] [4.0 Regression] ICE with nested template friend
--- Comment #3 from pinskia at gcc dot gnu dot org 2006-08-24 03:41 --- (In reply to comment #2) which g++-4.2 revision are you using to get ?: 4.2.0 20060821 aka two days ago's. I bet it was also fixed by 28304. You are using a month's old 4.2 compiler which is why you don't see the fix. If you are going to try the mainline, please try with at a max a week old compiler. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28827

[Bug tree-optimization/15452] [tree-ssa] Optimize cascaded a = a == 0;
--- Comment #6 from pinskia at gcc dot gnu dot org 2006-08-24 04:27 ---
Another interesting case would be (but which could be handled by VRP):
int
foo (int a)
{
a = a!=0;
a = a!=0;
a = a!=0;
a = a!=0;
a = a!=0;
return a;
}
Which should be optimized to:
int foo(int a) { return a!=0;}
