After being "hit" by unexplained division by 0 related crashes of an
application, the
following simple test code shows the issue:
#include

void TestSqrt(const float *Src,float *Dest,size_t Size,float )

builds without errors. closing. please reopen if you can reproduce
this on another machine, and provide maybe a complete example which
shows the error.

With the following simple test file, the 3DNow! generated code is
incorrect, with final _m_pfsub generated as pfsubr %mm0,%mm0, thus
producing completely incorrect result.
*** main.c
#include
With fresh install of Debian Unstable the error is still present. By using:
gcc -march=athlon -fverbose-asm -S -O3 -save-temps main.c
all I see is an empty (0 bytes) main.i file and compile process still
ends with

When trying to compile the following very simple test file:

Right now I see gcc 4.4.2-4 available for Debian unstable. I have
upgraded the compilers but I still get:

This is a Virtual Box installed Debian unstable. With older GCC
versions, 4.3.2 (Debian stable) and 4.3.4 (Debian testing) the same

With the attached source file, the code generated is incorrect for the final
_m_pfsub. The compiler generates things like PFSUBR %MM0,%MM0.
The command line showing the problem is:
gcc -march=athlon -fverbose-asm -S -O3 main.c
