From 3c7825844aa985429774a0d9e0f4d10bece86b79 Mon Sep 17 00:00:00 2001 From: bonzini Date: Mon, 30 Aug 2004 08:02:34 +0000 Subject: 2004-08-26 Paolo Bonzini * Makefile.def (bootstrap stages): Add 'lean' parameter. * Makefile.tpl (configure-stageN-*, all-stageN-*): Turned into phony targets; do not generate timestamp files. (distclean-stageN): Remove references to their timestamp files. (restageN, touch-stageN): Remove. (stageN-bubble): Rewritten. (compare): Support lean bootstraps. * Makefile.in: Regenerate. * configure.in: Only warn when bootstrapping but build != host or build != target. Support lean bootstraps. * configure: Regenerate. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@86754 138bc75d-0d04-0410-961f-82ee72b054a4 --- configure | 131 +++++++++++++++++++++++++++++++++++++++----------------------- 1 file changed, 83 insertions(+), 48 deletions(-) (limited to 'configure') diff --git a/configure b/configure index 72580d11bb9..f76883b1adc 100755 --- a/configure +++ b/configure @@ -24,7 +24,7 @@ ac_help="$ac_help ac_help="$ac_help --with-gmp=PATH Specify directory for installed GMP library" ac_help="$ac_help - --enable-bootstrap Enable bootstrapping [no]" + --enable-bootstrap[=lean] Enable bootstrapping [no]" ac_help="$ac_help --enable-serial-[{host,target,build}-]configure Force sequential configuration of @@ -3098,23 +3098,56 @@ if test "${enable_bootstrap+set}" = set; then enableval="$enable_bootstrap" : else - enable_bootstrap=no + enable_bootstrap=default fi -if test -d ${srcdir}/gcc; then - case "$host:$target:$enable_bootstrap" in - $build:$build:yes | *:no) ;; - *:yes) { echo "configure: error: cannot bootstrap a cross-compiler" 1>&2; exit 1; } ;; - *) { echo "configure: error: invalid option for --enable-bootstrap" 1>&2; exit 1; } ;; - esac -else - if test $enable_bootstrap = yes; then - { echo "configure: error: cannot bootstrap without a compiler" 1>&2; exit 1; } - fi -fi +# Issue errors and warnings for invalid/strange bootstrap combinations. +case "$configdirs" in + *gcc*) have_compiler=yes ;; + *) have_compiler=no ;; +esac + +case "$have_compiler:$host:$target:$enable_bootstrap" in + *:*:*:no) ;; + + # Default behavior.
