bits ASM instruction

[Guest]

Does anyone know what this asm instruction does?

Code: Select all

bits %ireq, 15

AT&T or NASM?

Hmmm... no such opcode in either the Pentium manuals or Art of Assembly... no such thing in the NASM or GAS manuals either... where did you find it?

found it in some PowerPC code. But couldnt find anything in that manual either.

Telling that it's PPC code beforehand could have helped.

Nah, I come up empty too. My google-foo is weak today. What does that opcode disassemble into? That might be different, and give a hint...

Could it be roughly equivalent to the Intel BTS instruction?
