== Progress ==

* LLD Port: - Got hello world running. -- Needed a horrible hack to make lld output PLT and GOT entries for unresolved weak references with default visibility. - Wrote up in Jira the major areas of work that would be needed for a useful port. - Started putting in changes cleanly and writing tests for them. - Currently hitting a few problems with llvm-mc. I can't generate the relocations I need to test the linker. The hello world test case used mainly GCC library objects. -- Most serious is not emitting R_ARM_BASE_PREL for .word _GLOBAL_OFFSET_TABLE - (label+8)

== Plan == * On holiday Monday and Tuesday * LLVM MC See how easy it would be to add missing features to llvm-mc as it would allow me to write more tests.

* LLD Complete the test cases for the code I've added. Take stock of where the lld port is and decide where to go from there. Options are: - Send an RFC upstream with what I have. It is not sufficient to run hello world but should be relatively uncontroversial. - Cleanly implement the emit the unresolved weak references in the PLT and GOT so hello world will work out of the box on ARM. - Keep going until I've got Thumb2 support so I don't have to use ARM only static libraries to make hello world working. There is obviously a trade off between having a useful linker and the patch size getting out of hand.
