Yonghong Song 8d499bd5bc BPF: change btf_type_tag BTF output format ... For the declaration like below: int __tag1 * __tag1 __tag2 *g Commit 41860e602a ("BPF: Support btf_type_tag attribute") implemented the following encoding: VAR(g) -> __tag1 --> __tag2 -> pointer -> __tag1 -> pointer -> int Some further experiments with linux btf_type_tag support, esp. with generating attributes in vmlinux.h, and also some internal discussion showed the following format is more desirable: VAR(g) -> pointer -> __tag2 -> __tag1 -> pointer -> __tag1 -> int The format makes it similar to other modifier like 'const', e.g., const int *g which has encoding VAR(g) -> PTR -> CONST -> int Differential Revision: https://reviews.llvm.org/D113496		2021-11-09 11:34:25 -08:00
