From 55f917a1e8f003d3a45f41e8526ed750a0da900e Mon Sep 17 00:00:00 2001 From: "Ralf S. Engelschall" Date: Tue, 1 Jul 2003 15:04:50 +0000 Subject: [PATCH] Unfortunately, the GCC documentation and the implementation diverge dramatically: BOOT_CFLAGS is not for stage1 (booting), but for stage2, stage3, etc. And LIBCFLAGS are used for libiberty, but no BOOT_LIBCFLAGS exists (BOOT_LIBCXXFLAGS are not required, btw). To allow GCC to build correctly with a non-GCC vendor compiler, we no longer set LIBCFLAGS at all (because libiberity build would fail) and we use CFLAGS for the stage1 and BOOT_CFLAGS for stage2, stage3, etc. So, beastie GCC, DWIM now, please! --- gcc/gcc.spec | 16 +++++++--------- 1 file changed, 7 insertions(+), 9 deletions(-) diff --git a/gcc/gcc.spec b/gcc/gcc.spec index 5b5204f56e..62cf60fb5f 100644 --- a/gcc/gcc.spec +++ b/gcc/gcc.spec @@ -135,30 +135,28 @@ Provides: gcc = %{version}-%{release} `find . -name Makefile -type f -print` # determine build flags - l_boot_cflags="" l_cflags="" + l_boot_cflags="" l_libcflags="-g" l_libcxxflags="-g" %if "%{with_binutils}" == "yes" # at least GNU as from GNU binutils supports -pipe always - l_cflags="$l_cflags -pipe" - l_libcflags="$l_libcflags -pipe" + l_boot_cflags="$l_boot_cflags -pipe" l_libcxxflags="$l_libcxxflags -pipe" %endif %if "%{with_optimize}" == "yes" # conservatively optimize the generated program code # (also _tune_ for particular CPUs, but _without_ requiring these CPUs!) - l_cflags="$l_cflags -O2 -fomit-frame-pointer -funroll-loops" + l_cflags="$l_cflags -O" + l_boot_cflags="$l_boot_cflags -O2 -fomit-frame-pointer -funroll-loops" case "%{l_target}" in - *x86-* ) l_cflags="$l_cflags -mcpu=pentium3" ;; - *sparc64-* ) l_cflags="$l_cflags -mtune=v9" ;; + *x86-* ) l_boot_cflags="$l_boot_cflags -mcpu=pentium3" ;; + *sparc64-* ) l_boot_cflags="$l_boot_cflags -mtune=v9" ;; esac - l_libcflags="$l_libcflags -O2" l_libcxxflags="$l_libcxxflags -O2 -fno-implicit-templates" %else # else do no optimizations at all to reduce problems to minimum in advance - l_cflags="$l_cflags -O0" - l_libcflags="$l_libcflags -O0" + l_boot_cflags="$l_boot_cflags -O0" l_libcxxflags="$l_libcxxflags -O0" %endif
