From 864198ed3011a446f42fc9dcb6d39617ce2477ea Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 19 Oct 2015 22:34:20 +0000 Subject: Remove gnu_unique_object configure test. There is a configure test for assembler support for the gnu_unique_object symbol type. This support was added in binutils 2.20, so is present in all versions supported for building glibc. Thus, I think the configure test can be removed; this patch does so. Now, there is a caveat that the gas NEWS entry refers to this as a feature for GNU/Linux targets. But the condition is use of ELFOSABI_GNU or ELFOSABI_NONE. ELFOSABI_GNU covers Hurd as well as GNU/Linux (as was the case with the older ELFOSABI_LINUX name), and ELFOSABI_NONE means this is effectively OS-independent. Furthermore, I think a correct binutils port for any glibc target ought to support this feature for use with glibc; glibc supports this as an OS-independent feature (the configure test is only about glibc testcases). Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_asm_unique_object): Remove configure test. * configure: Regenerated. * config.h.in (HAVE_ASM_UNIQUE_OBJECT): Remove #undef. * elf/tst-unique1.c (do_test) [HAVE_ASM_UNIQUE_OBJECT]: Make code unconditional. * elf/tst-unique1mod1.c [HAVE_ASM_UNIQUE_OBJECT]: Likewise. * elf/tst-unique1mod2.c [HAVE_ASM_UNIQUE_OBJECT]: Likewise. * elf/tst-unique2.c (do_test) [HAVE_ASM_UNIQUE_OBJECT]: Likewise.
