- Don't use gold for linking anymore: on s390x we use ld.bfd with LLVMgold.so, on ppc64 we disable ThinLTO for now. (boo#1210688) - Using ld.bfd on s390x exposed an issue with the existing llvm_build_tablegen_component_as_shared_library.patch: linking llvm-tblgen with libLLVM.so means we also have to link libraries used for that (like LLVMTableGenGlobalISel) with libLLVM.so. - Rewrite summary and description for llvm-gold to point out that it can also be used with ld.bfd, recommend with binutils.

The LLVMTableGen component is a special case that is excluded from libLLVM and
|
|
normally is only built as static library and linked into llvm-tblgen.
|
|
|
|
We need to have it as a shared library to be available for other projects such
|
|
as ldc.
|
|
|
|
This patch makes it even more special and forces it to be build and installed
|
|
as separate shared library.
