Subject: [PATCH v2 0/3] RISC-V: Disable DWARF5 with known broken LLVM versions
Date: Tue, 05 Dec 2023 16:53:49 -0700 [thread overview]
Message-ID: <20231205-riscv-restrict-dwarf5-llvm-v2-0-aedf00a382ac@kernel.org> (raw)
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
