i386-mingw32-gcc can't find register in class FP_TOP_REG

[Bernd Jendrissek <berndj at prism dot co dot za>]

Hi

I have a compiler error at -O2 that goes away at -O0:

/mnt/disk2/src/mingw/mingw-runtime-3.0/mingwex: PATH=/usr/cross/bin:$PATH i386-mingw32-gcc -c  -g -O2   -fomit-frame-pointer -I ./../../w32api/include -I. -I./../include -nostdinc -nostdinc++ -iwithprefixbefore include -da ./math/pow.c -o pow.o
math/pow.c: In function `pow':
../include/math.h:174: error: can't find a register in class `FP_TOP_REG' while reloading `asm'

Here's that part of the header:

#if !defined (__NO_INLINES__)
extern __inline__ __cdecl double fabs (double x)
{
  double res;
  __asm__ ("fabs;" : "=t" (res) : "0" (x));
  return res;
}
#endif

Unfortunately I don't know what do do with all those -da output files.

But I do have a testcase derived from the mingw-runtime and w32-api sources
(attached).

employer-specific email address I may have appearing in the headers.
