Changes since v6:
- Address Ian's comments including,
* Add more comments for newly added register indexes (patch 1/4).
* Several minor enhancements in patch 4/4.
- Limit dwarf minimal regs to legacy GPRs (excluding APX eGPRs)
(patch 2/4).
Changes since v5:
- Split the sampling support for eGPRs/SSP registers and SIMD registers
into 2 patches.
- Address Ian's comments including,
* Convert the architecture dependent functions into regular
architectural independent functions, like whatperf_reg_name() does.
* Refine the functions name to represent what the functions really do.
* Add comments for some key functions arguments.
* Misc enhancements.
This patch-set adds sampling support for x86 eGPRs/SSP/SIMD registers in
perf tools base on the corresponding sampling support for eGPRs/SSP/SIMD
registers in kernel[1]. In versions before v6, these perf-tools patches
are integrated as a whole patch-set with the kernel patches, but it's
split and posted to an independent perf-tools patch-set for convenient
review.
