I've noticed a number of issues and inefficiencies.
01: x86: record flag_code in tc_frag_data
02: x86: i386_generate_nops() may not derive decisions from global variables
03: x86: don't use 32-bit LEA as NOP surrogate in 64-bit code
04: x86: don't use operand size override with NOP in 16-bit code
05: x86: respect ".arch nonop" when selecting which NOPs to emit
06: x86: i686 != PentiumPro
07: x86: don't record full i386_cpu_flags in struct i386_tc_frag_data
08: x86: add a few more NOP patterns
09: x86: fold a few of the "alternative" NOP patterns
10: x86: fold NOP testcase expecations where possible
11: gas: make .nops output visible in listing
