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 ':'
