2024-05-17gprofng: add hardware counters for AMD Zen3Vladimir Mezentsev7-122/+184
Historically, we have used several APIs (perfctr, libcpc, perf_event_open) for profiling. 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.

2024-01-10gprofng: 31123 improvements to hardware event implementationVladimir Mezentsev7-147/+182
Our hardware counter profiling is based on perf_event_open(). 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 <vladimir.mezentsev@oracle.com> PR gprofng/31123 * common/core_pcbe.c: Mark the symbols as static.

2024-01-04Update year range in copyright notice of binutils filesAlan Modra15-15/+15
Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.

This adds 'Innovative Computing Labs' as an external author to update-copyright.py, to cover the copyright notice in gprofng/common/opteron_pcbe.c, and uses that plus another external author 'Oracle and' to update gprofng copyright dates. I'm not going to commit 'Oracle and' as an accepted author, but that covers the string "Copyright (c) 2006, 2012, Oracle and/or its affiliates.

2022-07-09Regenerate with automake-1.15.1Alan Modra1-1/+27
Until we update the recommended versions of autoconf/automake, files should be regenerated with automake-1.15.1 and autoconf-2.69. That's not because we think those versions are golden, and newer versions are bad. It's simply because maintainers want to be able to update configury files without trouble, and if someone regenerates files with automake-1.16.5 then --enable-maintainer-mode builds will hit errors: checking that generated files are newer than configure... configure.ac:26: error: version mismatch. This is Automake 1.15.1, configure.ac:26: but the definition used by this AM_INIT_AUTOMAKE configure.ac:26: comes from Automake 1.16.5. You should recreate configure.ac:26: aclocal.m4 with aclocal and run automake again. WARNING: 'automake-1.15' is probably too old. Correcting this requires regenerating the files by hand.
