Support dumping of SIMD registers with the new PERF_SAMPLE_REGS_ABI_SIMD ABI. Currently, the XMM, YMM, ZMM, OPMASK, eGPRs, and SSP registers on x86 platforms are supported with the PERF_SAMPLE_REGS_ABI_SIMD ABI. An example of the raw format output is displayed below. Example: $perf record -e cycles:p -Iax,bx,r8,r16,r31,ssp,xmm,ymm,zmm,opmask ./test $perf report -D ... ... 3342715685845 0x3afe8 [0xbc8]: PERF_RECORD_SAMPLE(IP, 0x1): 27776/27776: 0xffffffff91d7c18f period: 10000 addr: 0 ... intr regs: mask 0x18001010003 ABI 64-bit SIMD ....
