From e4f5eae8f004f236db11325df2adf338766c0543 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 27 Oct 2015 10:46:15 +0000 Subject: Remove configure test for needing -P for .S files. There is a configure test for "whether we need to use -P to assemble .S files". I think this test is long obsolete. I don't have a specific reference to a binutils change or version that obsoleted this test, but: (a) we only support GNU binutils; (b) it looks like every architecture supported by glibc has '#' as a line comment character in its gas port; (c) in any case, if the (compiler, assembler) combination in use cannot compile a .S file without special options, that would clearly be a substantially broken combination, which I don't think we need to allow for at all. The test in question was added by: Thu Jan 27 16:46:03 1994 Roland McGrath (roland@churchy.gnu.ai.mit.edu) * configure.in (asm-CPPFLAGS): Add new check to see if assembling a .S file loses without -P. If so, set asm-CPPFLAGS=-P in config.make. This patch removes the test and the reference to this issue in the comment on the default empty definition of asm-CPPFLAGS. (Various other settings of asm-CPPFLAGS remain in sysdeps Makefile fragments.) Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_need_minus_P): Remove configure test. * configure: Regenerated. * Makeconfig (asm-CPPFLAGS): Remove reference to -P in comment. --- Makeconfig | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'Makeconfig') diff --git a/Makeconfig b/Makeconfig index f3668c616a..c0f5e64ef5 100644 --- a/Makeconfig +++ b/Makeconfig @@ -345,9 +345,7 @@ endif endif # Flags to pass the C compiler when assembling preprocessed assembly code -# (`.S' files).
