Bug #: 52544
Summary: compilation fails with -finstrument-functions and sse
c code
Classification: Unclassified
Product: gcc
Version: 4.6.3
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: jgpiccin...@free.fr
Created attachment 26866
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26866
the src code that reproduce the issue.
Hi,
I'd like to report an issue with gcc versions >= 4.6.x :
when compiling my sse.c code with "gcc -Wall -Wextra -fno-strict-aliasing
-fwrapv sse.c",
all versions of gcc (434, 453, 462, 463, 47 and 480) create a correct
executable,
that will give the correct output at runtime :
* x = [1.250000 1.250000 1.250000 1.250000]
BUT
if i add "-finstrument-functions" to the compilation line,
then only version < 4.6.x (versions 434 and 453 in my tests) will compile my
code,
otherwise (= gcc versions 462, 463, 47 and 480), compilation will stop with the
following message :
* /tmp/cckYj6ai.o: In function `main':
* sse.c:(.text+0x2a): undefined reference to `_mm_set1_ps'
* sse.c:(.text+0x50): undefined reference to `_mm_set1_ps'
* sse.c:(.text+0x79): undefined reference to `_mm_store_ps'
* sse.c:(.text+0x95): undefined reference to `_mm_store_ps'
* collect2: ld returned 1 exit status
gcc was compiled with :

--enable-shared \
--with-mpfr=/apps/rothorn/mpfr/3.0.0/gcc-4.3.4 \

gcc/4.7 was compiled with revision 184577 of the svn.
gcc/4.8.0 was compiled with revision 185132 of the svn.
Tested on GNU/Linux with Intel (Ubuntu/11.04) and AMD (SLES/11.1) cpus.
What's wrong please ?
Thanks in advance for your help.
The original src is sse.c :
#include <stdio.h>
#include <xmmintrin.h>
int main(void)
{
float xf[4];
__m128 x = _mm_set1_ps(1.25f);
_mm_store_ps(&xf[0], x);
printf("x = [%f %f %f %f]\n", xf[0], xf[1], xf[2], xf[3]);
return 0;
}
The preprocessed src (with gcc version 4.6.3) is attached, and the full output
is here :
rothorn:/apps/rothorn/sandbox/jgp/gcc/bugA $ ./463 -v -save-temps -Wall -Wextra
-fno-strict-aliasing -fwrapv sse.c -finstrument-functions
