From a009d53c4d97e4b9ffe17cb2f6442a40e7407ac8 Mon Sep 17 00:00:00 2001 From: Duncan Sands Date: Wed, 17 Jul 2013 09:34:51 +0000 Subject: Tweak the cmake interaction between CMAKE_BUILD_TYPE and LLVM_ENABLE_ASSERTIONS. The issue is that CMAKE_BUILD_TYPE=RelWithDebInfo LLVM_ENABLE_ASSERTIONS=ON was not building with assertions enabled. (I was unable to find what in the LLVM source tree was adding -DNDEBUG to the build line in this case, so decided that it must be cmake itself that was adding it - this may depend on the cmake version). The fix treats any mode that is not Debug as being the same as Release for this purpose (previously it was being assumed that cmake would only add -DNDEBUG for Release and not for RelWithDebInfo or MinSizeRel). If other versions of cmake don't add -DNDEBUG for RelWithDebInfo then that's OK: with this change you just get a useless but harmless -UNDEBUG or -DNDEBUG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186499 91177308-0d34-0410-b5e6-96231b3b80d8 --- cmake/modules/HandleLLVMOptions.cmake | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'cmake') diff --git a/cmake/modules/HandleLLVMOptions.cmake b/cmake/modules/HandleLLVMOptions.cmake index 2939fa2afa..bc6dd0ccd8 100644 --- a/cmake/modules/HandleLLVMOptions.cmake +++ b/cmake/modules/HandleLLVMOptions.cmake @@ -17,9 +17,9 @@ if( LLVM_ENABLE_ASSERTIONS ) if( NOT MSVC ) add_definitions( -D_DEBUG ) endif() - # On Release builds cmake automatically defines NDEBUG, so we + # On non-Debug builds cmake automatically defines NDEBUG, so we # explicitly undefine it: - if( uppercase_CMAKE_BUILD_TYPE STREQUAL "RELEASE" ) + if( NOT uppercase_CMAKE_BUILD_TYPE STREQUAL "DEBUG" ) add_definitions( -UNDEBUG ) # Also remove /D NDEBUG to avoid MSVC warnings about conflicting defines. string (REGEX REPLACE "(^| )[/-]D *NDEBUG($| )" " " -- cgit v1.2.3
