3 daysgprofng: support external debug infoVladimir Mezentsev15-185/+279
Use bfd_follow_gnu_debuglink() and bfd_follow_gnu_debugaltlink() to find files with debug info. If necessary, gprofng-archive copies these files to EXP/archives. For each executable, gprofng creates the Elf class twice. One of them was a memory leak. Fixed this by adding a new argument to Stabs::Stabs(). gprofng/ChangeLog 2025-07-07 Vladimir Mezentsev <vladimir.mezentsev@oracle.com> PR 32147 PR 30194 * src/Disasm.cc (get_funcname_in_plt): Use the executable file instead of the debug information file. * src/Dwarf.h: Define debug_alt_strSec. * src/DwarfLib.cc: Add support for DW_FORM_GNU_ref_alt, DW_FORM_GNU_strp_alt. * src/Elf.h (find_gnu_debug_files, get_dwr_section): New functions. * src/Elf.cc: Likewise. * src/Experiment.cc (copy_file): Add the const qualifier. * src/Experiment.h: Likewise. * src/LoadObject.cc (get_elf, openDebugInfo): Find files with debug info. * src/LoadObject.h: Remove unused variables. * src/Module.cc: Remove an argument in openDebugInfo(). * src/Stabs.cc (Stabs::Stabs): Add the Elf* argument. * src/Stabs.h: Likewise. * src/gp-archive.cc: Archive files with debug info. * src/gp-archive.h (archive_file): New function.

2025-04-28gprofng not reading references correctly in DwarfVladimir Mezentsev2-9/+9
Fixed as specified in the DWARF standard: The first type of reference can identify any debugging information entry within the containing unit. This type of reference is an offset from the first byte of the compilation header for the compilation unit containing the reference. There are five forms for this type of reference. There are fixed length forms for one, two, four and eight byte offsets (respectively, DW_FORM_ref1, DW_FORM_ref2, DW_FORM_ref4, and DW_FORM_ref8). There is also an unsigned variable length offset encoded form that uses unsigned LEB128 numbers (DW_FORM_ref_udata). gprofng/ChangeLog 2025-04-27 Vladimir Mezentsev <vladimir.mezentsev@oracle.com> * src/DwarfLib.cc (set_die): Handling DWARF references (DW_FORM_ref1, DW_FORM_ref2, DW_FORM_ref4, DW_FORM_ref8, DW_FORM_ref_udata). * src/Dwarf.cc: Likewise.

2025-04-06gprofng: Remove duplicate symbolsClaudiu Zissulescu3-0/+43
Remove all duplicate symbols which can be in SymLst. The duplication is due to processing of both static and dynamic symbols. The Stabs::removeDupSyms function is called before computing symbol aliases. Introduce a new vector function (i.e., truncate()), that truncates a vector lenght to the given new count. This functionis used by removeDupSyms function. Signed-off-by: Claudiu Zissulescu <claudiu.zissulescu-ianculescu@oracle.com>
2025-04-06gprofng: Refactor readSymSec for using BFD's asymbol structClaudiu Zissulescu5-81/+59
This patch refactors a number of gprofng internal functions for using more BFD data types and functions. Stabs::readSymSec is a function which reads the symbols of an ELF file mapping them into an internal structure. To use BFD asymbols, the Elf::elf_getsym is changed from custom reading of the symbols from .symtab and .dynsym section to BFD enable functions. A new function is introduced which returns the number of either static or dynamic symbols, named Elf::elf_getSymCount. Both Elf functions are used by Stabs::readSymSec refactoring. Also, this patch removes reading symbols, SUNW_ldnsym section as it is only used by now defunct Studio compiler. However, it adds the reading of both static and dynamic symbols, previously, only either one was processed. Signed-off-by: Claudiu Zissulescu <claudiu.zissulescu-ianculescu@oracle.com>

2024-05-17gprofng: add hardware counters for AMD Zen3Vladimir Mezentsev3-4/+636
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.

2024-05-08Fix hard-coded bash path in gprofngVladimir Mezentsev1-0/+1
When running 'make check', the default gprofng test suite creates a shell script for which it used a hardcoded shebang of '/usr/bin/bash' this script would not run if bash is in a different location, like /bin/bash This commit adds 'AC_PATH_PROG(BASH, bash)' to configure.ac so the installation path of bash is detected at configuration time. The configuration is propagated to the runtest command line where it is needed.
2024-01-22Fix 31252 gprofng causes testsuite parallel jobs failVladimir Mezentsev1-7/+29
Before running our tests, we made a fake installation into ./tmpdir. This installation changes libopcodes.la in the build area. Gas testing may fail if gas and gprofng tests are run in parallel. I create a script to run gprofng. Inside this script, LD_LIBRARY_PATH, GPROFNG_SYSCONFDIR are set. putenv_libcollector_ld_misc() first uses $GPROFNG_PRELOAD_LIBDIRS to create directories for SP_COLLECTOR_LIBRARY_PATH ($SP_COLLECTOR_LIBRARY_PATH is used to set up LD_PRELOAD). gprofng/ChangeLog 2024-01-19 Vladimir Mezentsev <vladimir.mezentsev@oracle.com> PR gprofng/31252 PR gprofng/30808 * src/envsets.cc (putenv_libcollector_ld_misc): Use $GPROFNG_PRELOAD_LIBDIRS first to build SP_COLLECTOR_LIBRARY_PATH. * testsuite/config/default.exp: Create a script to run gprofng. * testsuite/lib/display-lib.exp: Fix typo.

2024-01-10gprofng: 31123 improvements to hardware event implementationVladimir Mezentsev1-100/+111
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.

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.
