The patch also fixes the issue of BTF_KIND_FUNC appearing in the comments with a 'null' string. For btf-function-6.c testcase, after the patch: .long 0 # TYPE 2 BTF_KIND_FUNC_PROTO '' .long 0xd000002 # btt_info: kind=13, kflag=0, vlen=2 .long 0x1 # btt_type: (BTF_KIND_INT 'int') .long 0 # farg_name .long 0x1 # farg_type: (BTF_KIND_INT 'int') .long 0 # farg_name .long 0x1 # farg_type: (BTF_KIND_INT 'int') .long 0 # TYPE 3 BTF_KIND_FUNC_PROTO '' .long 0xd000001 # btt_info: kind=13, kflag=0, vlen=1 .long 0x1 # btt_type: (BTF_KIND_INT 'int') .long 0x68 # farg_name .long 0x1 # farg_type: (BTF_KIND_INT 'int') .long 0x5 # TYPE 4 BTF_KIND_FUNC 'extfunc' .long 0xc000002 # btt_info: kind=12, kflag=0, linkage=2 .long 0x2 # btt_type: (BTF_KIND_FUNC_PROTO '') .long 0xd # TYPE 5 BTF_KIND_FUNC 'foo' .long 0xc000001 # btt_info: kind=12, kflag=0, linkage=1 .long 0x3 # btt_type: (BTF_KIND_FUNC_PROTO '') gcc/ChangeLog: PR debug/112768 * btfout.cc (get_btf_type_name): New definition. (btf_collect_datasec): Update dtd_name to the original type name string. (btf_asm_type_ref): Use the new get_btf_type_name function instead. (btf_asm_type): Likewise.
