From 48464e0ee1c2de5bcbf0d609348f55d0c301085d Mon Sep 17 00:00:00 2001 From: Daniel Dunbar Date: Mon, 18 Jan 2010 06:49:33 +0000 Subject: Add support for "platform" configurations, which define a suite of compiler-rt libraries to generate. - Each library may be built with different flags and for different architectures, and there is support for building Darwin style fat archives. - Uses an ambituous amount of make programming, but should be hidden to users and developers. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@93720 91177308-0d34-0410-b5e6-96231b3b80d8 --- Makefile | 147 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 143 insertions(+), 4 deletions(-) (limited to 'Makefile') diff --git a/Makefile b/Makefile index a5c0be352..5a6f01745 100644 --- a/Makefile +++ b/Makefile @@ -1,7 +1,7 @@ SubDirs := lib #
