Do you have any more info? All I know is this add/sub/set mess we've got, but that's a cross linking problem. I queued this up for testing, should show up on for-next soon.

Hi all, This series disables DWARF5 for LLVM versions where it is known to be broken due to linker relaxation: https://github.com/llvm/llvm-project/commit/bbc0f99f3bc96f1db16f649fc21dd18e5b0918f6 If I understand correctly, it sounds like GNU binutils has a similar issue but I am not sure of the status of the fixes and such, so I did not bother with checking for it but it should be easy to add if so desired. --- Changes in v2: - Added patch 3 with Fangrui's suggested improvements around CONFIG_AS_HAS_NON_CONST_LEB128. - Pick up Fangrui's Reviewed-by on patch 1. - Link to v1: https://lore.kernel.org/r/20231129-riscv-restrict-dwarf5-llvm-v1-0-ec0d368fb538@kernel.org --- Nathan Chancellor (3): riscv: Hoist linker relaxation disabling logic into Kconfig riscv: Restrict DWARF5 when building with LLVM to known working versions lib/Kconfig.debug: Update AS_HAS_NON_CONST_LEB128 comment and name arch/riscv/Kconfig | 14 ++++++++++++++ arch/riscv/Makefile | 4 +--- lib/Kconfig.debug | 12 +++++++----- 3 files changed, 22 insertions(+), 8 deletions(-) --- base-commit: 2cc14f52aeb78ce3f29677c2de1f06c0e91471ab change-id: 20231129-riscv-restrict-dwarf5-llvm-a9824bb974cb Best regards,
