Subject: [PATCH dwarves v2 0/2] btf: support typedef DW_TAG_LLVM_annotation
Date: Tue, 2 Nov 2021 16:35:00 -0700 [thread overview]
Message-ID: <20211102233500.1024582-1-yhs@fb.com> (raw)
Latest llvm is able to generate DW_TAG_LLVM_annotation for typedef
declarations. Latest bpf-next supports BTF_KIND_DECL_TAG for
typedef declarations. This patch implemented dwarf DW_TAG_LLVM_annotation
to btf BTF_KIND_DECL_TAG conversion. Patch 1 is for dwarf_loader
to process DW_TAG_LLVM_annotation tags. Patch 2 is for the
dwarf->btf conversion.
Changelog:
v1 -> v2:
- change some "if" statements to "switch" statement.
Yonghong Song (2):
dwarf_loader: support typedef DW_TAG_LLVM_annotation
btf_encoder: generate BTF_KIND_DECL_TAGs for typedef btf_decl_tag
