Bug ID: 107479
Summary: bpf: add __builtin_btf_type_id
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: david.faust at oracle dot com
Target Milestone: ---
LLVM supports a BPF builtin:
__builtin_btf_type_id (param, flag)
which returns the BTF type id of 'param' to the program,
and records a BPF CO-RE relocation according to 'flag'.
We should support the same functionality in GCC.
These are the relevant changes in LLVM and clang:
