--- Comment #8 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Nick Alcock <n...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=ea9c2009115d7e00732f5ad316c10a171fc66a53 commit ea9c2009115d7e00732f5ad316c10a171fc66a53 Author: Nick Alcock <nick.alc...@oracle.com> Date: Mon Sep 27 20:31:21 2021 +0100 libctf: try several possibilities for linker versioning flags Checking for linker versioning by just grepping ld --help output for mentions of --version-script is inadequate now that Solaris 11.4 implements a --version-script with different semantics. Try linking a test program with a small wildcard-using version script with each supported set of flags in turn, to make sure that linker versioning is not only advertised but actually works. The Solaris "GNU-compatible" linker versioning is not quite GNU-compatible enough, but we can work around the differences by generating a new version script that removes the comments from the original (Solaris ld requires #-style comments), and making another version script for libctf-nonbfd in particular which doesn't mention any of the symbols that appear in libctf.la, to avoid Solaris ld introducing corresponding new NOTYPE symbols to match the version script. libctf/ChangeLog 2021-09-27 Nick Alcock <nick.alc...@oracle.com> PR libctf/27967 * configure.ac (VERSION_FLAGS): Replace with... (ac_cv_libctf_version_script): ... this multiple test. (VERSION_FLAGS_NOBFD): Substitute this too. * Makefile.am (libctf_nobfd_la_LDFLAGS): Use it. Split out... (libctf_ldflags_nover): ... non-versioning flags here. (libctf_la_LDFLAGS): Use it. * libctf.ver: Give every symbol not in libctf-nobfd a comment on the same line noting as much. -- You are receiving this mail because: You are on the CC list for the bug.
