btf: support typedef DW_TAG_LLVM_annotation
|
expand
|
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.
