From 0621cb2e7dfd89f558a045f145f900b62379dcc2 Mon Sep 17 00:00:00 2001 From: Alp Toker Date: Wed, 16 Jul 2014 16:48:33 +0000 Subject: Make clang's rewrite engine a core feature The rewrite facility's footprint is small so it's not worth going to these lengths to support disabling at configure time, particularly since key compiler features now depend on it. Meanwhile the Objective-C rewriters have been moved under the ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still potentially worth excluding from lightweight builds. Tests are now passing with any combination of feature flags. The flags historically haven't been tested by LLVM's build servers so caveat emptor. llvm-svn: 213171 --- clang/lib/Rewrite/Frontend/FrontendActions.cpp | 192 ------------------------- 1 file changed, 192 deletions(-) delete mode 100644 clang/lib/Rewrite/Frontend/FrontendActions.cpp (limited to 'clang/lib/Rewrite/Frontend/FrontendActions.cpp') diff --git a/clang/lib/Rewrite/Frontend/FrontendActions.cpp b/clang/lib/Rewrite/Frontend/FrontendActions.cpp deleted file mode 100644 index 4394e993a41..00000000000 --- a/clang/lib/Rewrite/Frontend/FrontendActions.cpp +++ /dev/null @@ -1,192 +0,0 @@ -//===--- FrontendActions.cpp ----------------------------------------------===// -// -// The LLVM Compiler Infrastructure -// -// This file is distributed under the University of Illinois Open Source -// License.
