[llvm-dev] RISC-V LLVM sync-up call 19th Dec 2019
For background on these calls, see <http://lists.llvm.org/pipermail/llvm-dev/2019-September/135087.html>. Reminder: the purpose is to co-ordinate between active contributors. If you have support questions etc then it's best to post to llvm-dev. We have a call each Thursday at 4pm GMT, via <https://meet.google.com/ske-zcog-spp>. NOTE: THERE WILL BE NO CALL NEXT WEEK DUE TO THE CHRISTMAS BREAK. Today's call might be a quiet one too with various people already off for the holidays. I've created a shared calendar which may help in keeping track, which is hopefully accessible at: * <https://calendar.google.com/calendar/b/1?cid=bG93cmlzYy5vcmdfMG41cGtlc2ZqY25wMGJoNWhwczFwMGJkODBAZ3JvdXAuY2FsZW5kYXIuZ29vZ2xlLmNvbQ> * <https://calendar.google.com/calendar/ical/lowrisc.org_0n5pkesfjcnp0bh5hps1p0bd80%40group.calendar.google.com/public/basic.ics> Issues to discuss today include the following: * Passing mabi in LTO https://reviews.llvm.org/D71387 * Machine outliner status - seems to be blocked by generic machine outliner bug that shows up in the gcc torture suite <https://reviews.llvm.org/D66210> * uleb128 relocation <https://github.com/riscv/riscv-elf-psabi-doc/pull/124>. Motivation was size reduction, some discussion about correctness - if there are cases where a uleb128 may increase after relaxation. * Weak, undefined symbols in non-PIC code. https://reviews.llvm.org/D71100 which we mentioned last week spawned this psabi issue <https://github.com/riscv/riscv-elf-psabi-doc/issues/126> * ilp32e work ongoing <https://reviews.llvm.org/D70401>. See <https://github.com/riscv/riscv-elf-psabi-doc/issues/125> which tries to clarify the ABI for variadic function calls, specifically for doubles on ilp32e. Best, Alex
