Subject[PATCH -tip perf/probes 04/10] x86: AVX instruction set decoder support
Date
Add Intel AVX(Advanced Vector Extensions) instruction set support to
x86 instruction decoder. This adds insn.vex_prefix field for storing
VEX prefixes, and introduces some original tags for expressing opcodes
attributes.
