[Bug middle-end/41069] lto1: error: type mismatch in indirect reference
--- Comment #16 from jv244 at cam dot ac dot uk 2009-08-17 07:39 --- (In reply to comment #15) -flto needs about 35min compile time and 10.5Gb RAM. Doh. How does that compare to the all-CP2K in one file builds? an all-in-one-file-CP2K takes about 2.5Gb and 30min last time I tested. So it is mostly the memory increase that is really significant. Ok, that's interesting. I'm curious if compiling all-in-one CP2K with -flto is any different. -flto wit hthe all-in-one CP2K fails, I guess it enable -fwhole-file automatically ? Since it looks like the same error: gfortran -O0 -march=native CP2K_2009-05-01.f90 -L/users/vondele/LAPACK/ -llapack_gfortran_4_4 -lblas_gfortran_4_4 Mem ~ 3.5Gb Time ~ 9m34.187 gfortran -O3 -march=native CP2K_2009-05-01.f90 -L/users/vondele/LAPACK/ -llapack_gfortran_4_4 -lblas_gfortran_4_4 Mem ~ 3.5Gb Time ~ 30m gfortran -flto -O3 -march=native CP2K_2009-05-01.f90 -L/users/vondele/LAPACK/ -llapack_gfortran_4_4 -lblas_gfortran_4_4 ICE on the PR40011 comment #40 (internal compiler error: in gfc_create_module_variable) thing. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41069

[Bug tree-optimization/41089] New: [4.5 Regression] r147980 (New SRA) breaks stdargs
r147980 [1] breaks stdargs on alpha [2]:

FAIL: gcc.dg/tree-ssa/stdarg-2.c scan-tree-dump stdarg f15: va_list escapes 1,
needs to save all GPR units and all FPR units
Before new SRA, stdarg dump for gcc.dg/tree-ssa/stdarg-2.c, f15 () showed:
--cut here--
va_list escapes in # .MEMD.2039_12 = VDEF .MEMD.2039_2
apD.2040 = apD.1263;
f15: va_list escapes 1, needs to save all GPR units and all FPR units.
--cut here--
With new SRA (r147980):
bb2 will be executed at most once for each va_start in bb2
bb3 will be executed at most once for each va_start in bb2
f15: va_list escapes 0, needs to save 8 GPR units and 0 FPR units.
The last OK testresults were from r147610 [3] and started to fail in r148747
[4]
The problem can be triggered by compiling following test (distilled from
stdarg-2.c) with a crosscompiler to alpha-linux-gnu:
--cut here--
typedef __builtin_va_list __gnuc_va_list;
typedef __gnuc_va_list va_list;
long x;
inline void __attribute__((always_inline))
f15_1 (va_list ap)
{
x = __builtin_va_arg(ap,long);
}
void
f15 (int i, ...)
{
va_list ap;
__builtin_va_start(ap,i);
f15_1 (ap);
__builtin_va_end(ap);
}
--cut here--
gcc -O2 -fdump-tree-stdarg.
Runtime failure will be triggered by following test (sorry for the debug
printk's):
--cut here--

# 1 command-line
# 1 t.c
# 1 /space/uros/gcc-build-44/gcc/include/stdarg.h 1 3 4

[Bug middle-end/41072] Alias stacked type cast interpretation regression
--- Comment #2 from sergei_lus at yahoo dot com 2009-08-17 16:35 --- First of all, I agree that a union would work better for type-punning, but... With all the respect I am not convinced that this is the case here. Even if I do something like this: tmp_ch = (char *)ans; tmp_sh = (unsigned short *)tmp_ch; I would expect tmp_ch to be aliased to everything, and it should in turn also hold for tmp_sh... unless you can say which standard (C99) rule says otherwise. ... but this argument aside, maybe you can explain why up to 4.3.2 GCC was ok with this code, and 4.4.0 explicitly changed its behavior - I could not readily track it down (could be my inability to trace it back). In a similar fashion I would appreciate a justification (C99 reference). Also, in 4.4.0 forwprop1 turns this: tmp_ch_10 = (char *) ans; tmp_sh_11 = (short unsigned int *) tmp_ch_10; into this: tmp_sh_11 = (short unsigned int *) ans; ...so alias analyzer does not even see the (char *) cast... 4.3.2 does not do this. The actual issue is that this breaks a long standing legacy code (a math library) and I see no provision to disable this new feature short of turning off strict aliasing all together. Thank you for your response - and information is very much appreciated. -- sergei_lus at yahoo dot com changed: What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|DUPLICATE | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41072

[Bug c++/41094] New: Erroneous optimization of pow() with -ffast-math
Consider the following program:
//--
#include iostream
#include cmath
int main()
{
for(double p = .25; p = .5; p += .25)
for(double x = -10.0; x = 10.0; x += 20.0)
{
std::cout
\nx*x = x*x
\npow(100, p ) = std::pow(100.0, p)
\npow(x*x, p ) = std::pow(x*x, p)
\n;
}
}
//--
When compiling without -ffast-math, the output is the expected one.
However, if compiled with -ffast-math (other optimization options don't
seem to matter), it produces incorrectly nan and -10 for the third
line (std::pow(x*x, p) when 'x' is negative.
If the -fno-unsafe-math-optimizations option is specified in addition
to -ffast-math, the bug is not triggered.
If double xx = x*x; is added inside the loop and then 'xx' is used
instead of 'x*x', the bug is not triggered either.

Richard, can you have a look? It's hot here ;) but first blush I don't see why

[Bug fortran/31593] Invariant DO loop variables and subroutines
--- Comment #40 from tobi at gcc dot gnu dot org 2009-08-17 22:08 --- Created an attachment (id=18392) -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18392action=view) Patch for savin function arguments This patch copies do loops which are passed as actual arguments to a temporary variable and then passes the temporary. The patch creates one copy for every single call, so this could be done better. Also, the naming is not finalized. Finally, this would need someone who is more familiar with the scalarizer's workings to make sure that it doesn't break anything. I'm actually surprised that the patch passes the testsuite. I don't plan to submit this, because Michael Matz is apparently working on something better, that would at least make part of this patch superfluous. See http://gcc.gnu.org/ml/fortran/2009-08/msg00200.html. If his patch goes in, the part that creates the copy could be dropped and instead the function argument could be properly labeled read-only. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31593

[Bug fortran/31593] Invariant DO loop variables and subroutines
--- Comment #41 from tobi at gcc dot gnu dot org 2009-08-17 22:39 --- (In reply to comment #40) One more thing: my previous benchmarks were wrong, I had an error in my setup. With a correct benchmark, polyhedron improves slightly in the testcases where the change is outside the measurement noise. This includes capacita.f90 which gains some 2%. Further, and as expected, with the patch, Thomas's testcases from comment #6 both run at the same speed that only the 'call by value' version did without the patch. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31593

[Bug target/41017] regparm=3 passes structures inconsistently
--- Comment #10 from hjl dot tools at gmail dot com 2009-08-18 04:49 --- (In reply to comment #3) Btw, the documentation claims regparm only affects integral parameters. Agreed, -regparm=N should only apply to integer parameters. I will take a look when I find time. BTW, -regparm=N is a gcc extension and out of psABI. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41017
