LLVM Makefile options

Hello,

We are linking our llvm build with other libraries and for testing purposes we use llc (bypassing our own driver). Because our backend has forward dependencies to our driver we added #defines to cut out the dependencies on our source. When we want to compile with our own driver, we compile llvm with “libs-only” and simply link the libraries.

Is there a way, on the makefile of our target machine, to know whether llvm is being compiled with “libs-only” target? We currently have to edit our sources every time we do a different build.

Thanks.

Dunno about the LLVM makefiles, but with the cmake build you could
achieve that by adding this to the CMakeFiles.txt of your backend:

if( $LLVM_BUILD_TOOLS )
  add_definitions( -DWE_ARE_BUILDING_WITH_TOOLS_TOO )
endif
