From c3c99d74c21d2e3b1c3370eda2f5a9187daae81e Mon Sep 17 00:00:00 2001 From: hainque Date: Wed, 16 May 2012 15:54:24 +0000 Subject: [PATCH] toplevel/ * Makefile.tpl (gcc-no-fixedincludes): Rename into ... (gcc-install-no-fixedincludes): Now forwarder to local target in gcc/ (install-no-fixedincludes): Adjust accordingly. * Makefile.in: Regenerate. gcc/ * Makefile.in (install-no-fixedincludes): New target, former toplevel gcc-no-fixedincludes. Stash "include-fixed" in addition to "include". Add comments and improve stamp preservation across the whole sequence. (stmp-int-hdrs): Use move-if-change + cp -p to setup fix_dir/limits.h. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/gcc-4_7-branch@187601 138bc75d-0d04-0410-961f-82ee72b054a4 --- ChangeLog | 7 +++++++ Makefile.in | 30 +++++++++++------------------- Makefile.tpl | 30 +++++++++++------------------- gcc/ChangeLog | 7 +++++++ gcc/Makefile.in | 46 +++++++++++++++++++++++++++++++++++++++++++++- 5 files changed, 81 insertions(+), 39 deletions(-) diff --git a/ChangeLog b/ChangeLog index 7f440c3acac..724b1f4612a 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,10 @@ +2012-05-16 Olivier Hainque + + * Makefile.tpl (gcc-no-fixedincludes): Rename into ... + (gcc-install-no-fixedincludes): Now forwarder to local target in gcc/ + (install-no-fixedincludes): Adjust accordingly. + * Makefile.in: Regenerate. + 2012-03-28 Georg-Johann Lay Backport from 2012-03-28 mainline r185907. diff --git a/Makefile.in b/Makefile.in index 86144c48934..4b991391572 100644 --- a/Makefile.in +++ b/Makefile.in @@ -2426,11 +2426,12 @@ install.all: install-no-fixedincludes true ; \ fi -# install-no-fixedincludes is used because Cygnus can not distribute -# the fixed header files. +# install-no-fixedincludes is used to allow the elaboration of binary packages +# suitable for distribution, where we cannot include the fixed system header +# files. .PHONY: install-no-fixedincludes install-no-fixedincludes: installdirs install-host-nogcc \ - install-target gcc-no-fixedincludes + install-target gcc-install-no-fixedincludes .PHONY: install-strip install-strip: @@ -40721,25 +40722,16 @@ check-gcc-go: check-go: check-gcc-go check-target-libgo -# Install the gcc headers files, but not the fixed include files, -# which Cygnus is not allowed to distribute.
