[gentoo-dev] [PATCH 0/4] llvm.eclass: EAPI 7 support

[Michał Górny]

Hi,

Here's my proposed EAPI 7 support for llvm.eclass.  I think it should
conceptually work with cross but I haven't tested it.  The main problem
is that we have multiple distinct ways of building LLVM, and AFAIU
when using CMake modules, you should be able to get away without having
LLVM in CBUILD.  However, when using llvm-config you obviously need
it CBUILD-executable.

To support both scenarios, get_llvm_prefix is now provided with '-b'
and '-d' options (matching those to has_version).  Using them, you can
choose the behavior suitable for your package.

I've left the default at '-d'.  I don't really know which is better
for the generic cross case but either way should work for non-cross
setups.
