Subject: [PATCH v5 0/6] LoongArch linker relaxation support.
Date: Fri, 26 May 2023 15:38:27 +0800 [thread overview]
Message-ID: <20230526073833.3933735-1-mengqinggang@loongson.cn> (raw)
This is the v5 version of patches to support loongarch linker relax.
This week, the kernek and grub was tested.
For kernel, I just did a simple test. It can be compiled correctly and
the OS can boot normally.
There are some "unsupported relocation" compile errors for grub,
because grub currently does not support relax/b16/b21/add/sub
relocations.
The new LoongArch ABI gitub repo will be released in the next
few days.
The patch set changelog:
v4 -> v5:
1. Change LOONGARCH to LoongArch.

LoongArch: opcodes: Add support for linker relaxation.
LoongArch: binutils: Add support for linker relaxation.
