Hi,
Trying to compile the following inline asm statement:
asm("fmull %[twopi]\n\t" \
"fsincos\n\t" \
"fadd %%st(0), %%st(0) \n\t" \
"fxch \n\t" \
"fadd %%st(0), %%st(0)\n\t" \
"fxch %%st(2) \n\t" \
"fld1 \n\t" \
"fsub %%st(1), %%st(0) \n\t" \
"fld %%st(1) \n\t" \
"fmul %%st(1), %%st(0) \n\t" \
"fsqrt \n\t" \
"fmul %%st(0), %%st(3) \n\t" \
"fmulp %%st(0), %%st(4) \n\t" \
"fsub %%st(1), %%st(0) \n\t" \
"fstpl %[zt] \n\t" \
"fstp %%st(0) \n\t" \
"fstpl %[xt] \n\t" \
"fstpl %[yt]" \
:[xt] "=m" (x), \
[yt] "=m" (y), \
[zt] "=m" (z) \
:[twopi] "F" (2*M_PI), \
"t" (drand48()), \
"u" (drand48()));
g++ errors with:
/tmp/cc7QJhi7.s: Assembler messages:
/tmp/cc7QJhi7.s:29: Error: junk `.28318530717958623199593e+0' after
expression
make: *** [light.o] Error 1
The .2831... is obviously the last part of 2*M_PI, so it seems to think
it's a integer imm?
Many thanks,
James
