Hello,
Can someone explain the value of including this in
mesa/src/gallium/Makefile.template:
ifeq ($(MESA_LLVM),1)
LIBRARY_DEFINES += $(LLVM_CFLAGS)
endif
?
This effectively adds the LLVM cflags to gcc compiles if LLVM is enabled. One
side-effect of this is to include -O3 optimization no matter what, making
debugging very difficult. Removing it seems to have no catastrophic effects (or
even detectable ones).
But maybe I am missing something.
We need some of the LLVM C flags to get the -I path for headers, for
example.
I think we should use llvm-config --cppflags instead of --cflags.
If you're using autoconf, try changing this line:
LLVM_CFLAGS=`$LLVM_CONFIG --cflags`
in configure.ac to use --cppflags instead. Does that help?
