From 7cd72ad38093e584cb143ac6e4b1453dee5f7ac7 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 28 May 2003 21:05:12 +0000 Subject: [PATCH] 2003-05-11 Andreas Schwab * Makerules: Always use -MP together with -MD. (sed-remove-dotot): Substitute $(..) also at start of line. ($(stdio_lim:h=st)): Use -MD instead of SUNPRO_DEPENDENCIES. Generated defines with a single compiler call. Use $(sed-remove-dotdot). * mach/Makefile ($(objpfx)mach-syscalls.mk): Use -MD instead of DEPENDENCIES_OUTPUT, and use $(sed-remove-objpfx). * sysdeps/unix/sysv/linux/Makefile ($(objpfx)syscall-%.h): Use -MD instead of SUNPRO_DEPENDENCIES, and use $(sed-remove-objpfx). * sysdeps/unix/sysv/linux/mips/Makefile ($(objpfx)syscall-%.h): Likewise. --- Makerules | 33 ++++++++++++--------------- mach/Makefile | 11 ++++++--- sysdeps/unix/sysv/linux/Makefile | 26 ++++++++++----------- sysdeps/unix/sysv/linux/mips/Makefile | 15 ++++++------ 4 files changed, 44 insertions(+), 41 deletions(-) diff --git a/Makerules b/Makerules index 1398b16646..c3d780800f 100644 --- a/Makerules +++ b/Makerules @@ -166,7 +166,7 @@ $(common-objpfx)%.make: $(..)%.make.c $(..)Makerules $(common-before-compile) rm -f $@T $@.dT (echo '# Generated from $*.make.c by Makerules.';
