Subject: [PATCH 1/5 v1] LoongArch: bfd: Add new reloc types.
Date: Mon, 18 Jul 2022 16:43:13 +0800 [thread overview]
Message-ID: <20220718084316.390672-1-liuzhensong@loongson.cn> (raw)
This is the v1 version of patches to support new relocs for LoongArch.
The new reloc types docnments are on:
https://github.com/loongson/LoongArch-Documentation/pull/57/files
The testsuite status:
=== binutils Summary ===
# of expected passes 241
# of unsupported tests 6
=== gas Summary ===
# of expected passes 270
# of unsupported tests 7
=== ld Summary ===
# of expected passes 1457
# of expected failures 11
# of untested testcases 1
# of unsupported tests 154
Add new reloc types support, the new relocate type
definition depends which operation needs of linker.
