Hi, all,
I'm using GCC 4.8.2 on x86-64 machine. The compiler emits tzcnt instruction
unlike previous gcc. I want to prevent using tzcnt instruction. As I know,
tzcnt instruction is BMI extension. To disable the feature, I set -mno-bmi
but it didn't work.
Is there any way to disable tzcnt instruction?
Thanks,
Hanhwi
