From b6abc5dbfa5342347828b9feb4d9060071ff819c Mon Sep 17 00:00:00 2001 From: Indu Bhagat Date: Mon, 4 Dec 2023 01:57:34 -0800 Subject: BTF: fix PR debug/112656 PR debug/112656 - btf: function prototypes generated with name With this patch, all BTF_KIND_FUNC_PROTO will appear anonymous in the generated BTF section. As noted in the discussion in the bugzilla, the number of BTF_KIND_FUNC_PROTO types output varies across targets (BPF with -mco-re vs non-BPF targets). Hence the check in the test case merely checks that all BTF_KIND_FUNC_PROTO appear anonymous. gcc/ChangeLog: PR debug/112656 * btfout.cc (btf_asm_type): Fixup ctti_name for all BTF types of kind BTF_KIND_FUNC_PROTO. gcc/testsuite/ChangeLog: PR debug/112656 * gcc.dg/debug/btf/btf-function-7.c: New test. --- gcc/btfout.cc | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'gcc/btfout.cc') diff --git a/gcc/btfout.cc b/gcc/btfout.cc index 1c25404..a5e0d64 100644 --- a/gcc/btfout.cc +++ b/gcc/btfout.cc @@ -820,6 +820,10 @@ btf_asm_type (ctf_container_ref ctfc, ctf_dtdef_ref dtd) btf_kind = BTF_KIND_ENUM64; } + /* PR debug/112656.
