Bug ID: 22798
Summary: CMAKE defines NDEBUG differently than Autoconf for
Assertions.
Product: new-bugs
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: new bugs

Classification: Unclassified
When going through _DEBUG, NDEBUG definitions found a difference between
autoconf and cmake.
llvm/Makefile.rules (MSVC case not applicable)
ifeq ($(DISABLE_ASSERTIONS),1)
CPP.Defines += -DNDEBUG
else
BuildMode := $(BuildMode)+Asserts
CPP.Defines += -D_DEBUG
endif
llvm/cmake/modules/HandleLLVMOptions.cmake
if( LLVM_ENABLE_ASSERTIONS )
# MSVC doesn't like _DEBUG on release builds. See PR 4379.
if( NOT MSVC )
add_definitions( -D_DEBUG )
endif()
# On non-Debug builds cmake automatically defines NDEBUG, so we
# explicitly undefine it:
if( NOT uppercase_CMAKE_BUILD_TYPE STREQUAL "DEBUG" )
add_definitions( -UNDEBUG )
# Also remove /D NDEBUG to avoid MSVC warnings about conflicting
defines.
