--- Comment #1 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Vladimir Mezentsev <vmeze...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=66f76c545b293f8b89fef0f996a3a48fa59fae61 commit 66f76c545b293f8b89fef0f996a3a48fa59fae61 Author: Vladimir Mezentsev <vladimir.mezent...@oracle.com> Date: Thu Mar 23 11:46:08 2023 -0700 gprofng: 30089 [display text] Invalid number of threads The real problem is that libcollector doesn't interpose thread_create@GLIBC_2.34 We interpose a lot of libC functions (dlopen, fork, pthread_create, etc.). Some of these functions have versions. For example, dlopen@GLIBC_2.34, dlopen@GLIBC_2.17, dlopen@GLIBC_2.2.5, etc. We have to interpose each of the functions because we don't know which version of libC will be used during profiling. Historically, we have used three versions of scripts (mapfile.aarch64-Linux, mapfile.amd64-Linux, mapfile.intel-Linux). Three are not needed. One is enough The fixes below include: - merged all version symbols into one version script. - added new version symbols which are defined in latest versions of libC. - removed unused defines and duplicated code. - added the DCL_FUNC_VER macro to define the version symbols. Tested on x86_64 and aarch64 (OL8/OL9). No regression. gprofng/ChangeLog 2023-03-23 Vladimir Mezentsev <vladimir.mezent...@oracle.com> PR gprofng/30089 * libcollector/Makefile.am: Use libgprofng.ver instead of mapfile.* * libcollector/configure.ac: Delete GPROFNG_VARIANT. * src/collector_module.h: Move the SYMVER_ATTRIBUTE macro to collector.h * libcollector/collector.h: Add macros (SYMVER_ATTRIBUTE, DCL_FUNC_VER).
