== 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. ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain

== Progress== * Remove exit-on-error flag from CodeGen tests [TCWG-604] [5/10] - This is a follow-up of TCWG-592: when changing the diag handler, some of the tests started to fail, so we had to add an exit-on-error flag to preserve the old behaviour until we can fix the tests. - Last week's patch fixing the MIR tests (PR27770) - still in upstream review - Last week's patch fixing an AMDGPU test (PR27762) - committed upstream - Last week's patch fixing a BPF test (PR27766) - committed upstream - Submitted another patch fixing a BPF test (PR27767) - committed upstream - Submitted another patch fixing two other BPF tests (PR27768/9) - in upstream review - Investigating one of the AMDGPU tests (PR27761) * Use git worktree in llvm helper scripts [TCWG-587] [4/10] - Started a RFC and a wiki page about the new workflow [1] - People seem to be in favour of it, but there are still some TODOs left before we can merge * Misc [1/10] - Meetings, buildbots == Plan == * Remove exit-on-error flag from CodeGen tests [TCWG-604] - Submit a patch for the AMDGPU test (PR27761) - More investigations on the ARM test (PR27765) * Use git worktree in llvm helper scripts [TCWG-587] - Finish the final touches and have a proper review [1] https://collaborate.linaro.org/display/LLVM/Git+Worktree+Proposal ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
