Add example/Skeleton.

This is a template that can be used to build your own LLVMC-based drivers.
It can be also useful as a "bare-bones" LLVMC.

15 years agoUse LLVMLIBS instead of USEDLIBS.
Mikhail Glushenkov [Tue, 3 Mar 2009 10:03:53 +0000 (10:03 +0000)]
Use LLVMLIBS instead of USEDLIBS.

Since this Makefile is supposed to be usable from LLVM-based projects not in the
tree, LLVMLIBS should be used instead of USEDLIBS. This depends on my previous
fix to Makefile.rules.

15 years agoLINK_COMPONENTS should be added to LLVMLibsOptions.
Mikhail Glushenkov [Tue, 3 Mar 2009 10:03:27 +0000 (10:03 +0000)]
LINK_COMPONENTS should be added to LLVMLibsOptions.

From the code: "There are "Proj" libs (defined by the user's project) and "LLVM"
libs (defined by the LLVM project)." LINK_COMPONENTS are clearly defined by the
LLVM project.

Additionally, this fixes an issue with llvmc's build process:-)
