Subject: In GCC4.8.2, mno-bmi option doesn't work
Date: Sun, 10 Aug 2014 03:46:00 -0000	[thread overview]
Message-ID: <1407642336296-1059078.post@n5.nabble.com> (raw)

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
