From 9147e853bf5d168c176eb3993f93bda12de96232 Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Thu, 13 Feb 2003 22:14:11 +0000 Subject: [PATCH] bfd/ * elflink.h (elf_link_add_object_symbols): Handle .symver x, x@FOO. ld/testsuite/ * ld-shared/shared.exp: Run on s390*-*-linux* and x86_64-*-linux* too. xfail tests linking non-pic code into shared libs on x86_64-*-linux*. * ld-elfvsb/elfvsb.exp: Likewise. * ld-elfvers/vers.exp: Likewise. Add vers24a, vers24b and vers24c tests. * ld-elfvers/vers3.ver: Allow VERS_2.0 to come before GLIBC_* version. * ld-elfvers/vers19.ver: Likewise. * ld-elfvers/vers24a.c: New test. * ld-elfvers/vers24b.c: New test. * ld-elfvers/vers24c.c: New test. * ld-elfvers/vers24.map: New test. * ld-elfvers/vers24.rd: New test. * lib/ld-lib.exp (run_ld_link_tests): Add optional 7th argument cflags.
