Remove .previous, .popsection configure tests.
There is a configure test for the assembler .previous directive, and, as a fallback, for .popsection. glibc now only supports ELF. For ELF, the GNU assembler has supported .previous since version 2.2 (support added by Mon Jul 19 15:21:20 1993 Ken Raeburn (raeburn@rtl.cygnus.com) * config/obj-elf.c (obj_elf_previous): New function. (previous_section, previous_subsection): New vars. (obj_elf_section): Save current place in case DWARF code wants us to pop back to it. Handle unquoted section name as well as quoted section name. Don't crash on invalid strings. (obj_pseudo_table): Handle new pseudos "previous", "2byte", and "4byte". ). Thus this configure test is obsolete, and this patch removes it (and with it the fallback .popsection test). Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_asm_previous_directive): Remove configure test. (libc_cv_asm_popsection_directive): Likewise. * configure: Regenerated. * config.h.in (HAVE_ASM_PREVIOUS_DIRECTIVE): Remove #undef. (HAVE_ASM_POPSECTION_DIRECTIVE): Likewise. * include/libc-symbols.h [HAVE_ASM_PREVIOUS_DIRECTIVE] (__make_section_unallocated): Make definition unconditional. [HAVE_ASM_POPSECTION_DIRECTIVE] (__make_section_unallocated): Remove conditional definition. [!HAVE_ASM_PREVIOUS_DIRECTIVE && !HAVE_ASM_POPSECTION_DIRECTIVE] (__make_section_unallocated): Likewise.
