For each hardware we have several tables of hardware counters. Some information is duplicated in these tables. Some of the information is no longer used. I did not touch the existing hwc tables. I added a new hwc table for an AMD Zen3 machine.

Our HWC tables are absent for new machines. I have added HWC tables for the following events: PERF_TYPE_HARDWARE, PERF_TYPE_SOFTWARE, PERF_TYPE_HW_CACHE. Other events require additional fixes. Did a little cleaning: marked the symbols as static, used Stringbuilder, created a function to read /proc/cpuinfo. gprofng/ChangeLog 2024-01-08 Vladimir Mezentsev PR gprofng/31123 * common/core_pcbe.c: Mark the symbols as static.
