... puzzling for me at least. A short time ago the following code compiled
nicely on the server machines using linux/g++ at my school:
inline int FirstSetBit(unsigned long long a)
{
asm ("
bsf 4(%0), %%eax
add $32, %%eax
bsf (%0), %%eax
":: "r"(&a): "%eax");
}
Since that time I suppose that there have been a number of upgrades and so forth
to my school computers. Unfortunately, now I get a number of errors. I fixed the
first few by simply appending ; \ to each line, but the compiler is still
unhappy. Specifically, it complains that the '%eax' register is unknown on the
final line. Can anyone give me any help?
Thanks,
James
