cltq addl %edx, %eax xorl %eax, %edxBut the register allocations constraints are pretty heavy considering that idivl already puts strain on the RA.Paolo, what does the cltq instruction do? I cannot find it in my x86 reference manuals...
Uhm, I meant cltd and it is the same as "cdq" in the intel syntax.cltq is an x86-64 instruction and it is the same as "cdqe" in the intel syntax.
