From d448292104a1ae72c5ec5d0f925691f57f6a13ee Mon Sep 17 00:00:00 2001 From: Jeffrey Yasskin Date: Fri, 25 Sep 2009 16:46:09 +0000 Subject: [PATCH] This patch causes the --enable-debug-runtime configure flag and the DEBUG_RUNTIME Makefile variable to pass -g to gcc when building LLVM's objects. Without this, it's very hard to debug crashes that happen in Release-Asserts mode but not Debug mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82775 91177308-0d34-0410-b5e6-96231b3b80d8 --- Makefile.rules | 7 +++++++ docs/MakefileGuide.html | 5 +++++ 2 files changed, 12 insertions(+) diff --git a/Makefile.rules b/Makefile.rules index 6cc4bd3cf3b..48cb690be28 100644 --- a/Makefile.rules +++ b/Makefile.rules @@ -313,6 +313,13 @@ ifeq ($(ENABLE_OPTIMIZED),1) CXX.Flags += $(OPTIMIZE_OPTION) $(OmitFramePointer) C.Flags += $(OPTIMIZE_OPTION) $(OmitFramePointer) LD.Flags += $(OPTIMIZE_OPTION) + ifdef DEBUG_RUNTIME + BuildMode := $(BuildMode)+Debug + CXX.Flags += -g + C.Flags += -g + LD.Flags += -g + KEEP_SYMBOLS := 1 + endif else BuildMode := Debug CXX.Flags += -g diff --git a/docs/MakefileGuide.html b/docs/MakefileGuide.html index f996144e145..8e552484abe 100644 --- a/docs/MakefileGuide.html +++ b/docs/MakefileGuide.html @@ -626,6 +626,11 @@
