[Qemu-devel] [PATCH 0/2] target/i386: Implement all TBM instructions

[Richard Henderson]

These are general purpose bit manipulation instructions akin
to the BMI1 and BMI2 instructions.  This is an AMD extension
and uses the XOP instruction prefix.

I am in the process of trying to run the gcc testsuite with -mtbm,
with and without the patchset, to see (1) if the new insns get used
and (2) that they run ok.

Please review.
