Missing Bit Manipulation Instruction Sets: ABM, BMI1, BMI2, and TBM

Open xelxebar opened this issue 3 years ago • 1 comments

Just recently having learned about the various Bit Manipulation Instruction Sets, I happened to notice their conspicuous lack on the x86reference. Is this intentional for some reason, or would it be worth a PR?

POPCNT is already there. LZCNT should be added.

BMI1, BMI2, and TBM are VEX-ecoded instructions and VEX encoding is yet to be implemented.
