Hi,
How can I convert the following WATCOM-style pragma to an inlined asm
function under DJGPP? I tried for hours but I cannot get it to work ;-(
#pragma aux FixMul= "imul ebx",
"shrd eax,edx,16",
parms [eax] [ebx] modify [edx] value
[eax];
I tried:
inline Fixed FixMul(int x, int y) __asm__ ( "imull %%ebx" \
"shrdl 16,%%edx,%%eax" \
:
"=a" : "a" (x), "b" (y): "%edx" );
but I think I'm doing something terribly wrong. the shrd opcode isn't even
recognized, and GCC (or GAS) gives a parse error before ':'
Regards,
