From 4d1ea705d797e66edd70ffa708b83888a210a437 Mon Sep 17 00:00:00 2001 From: Kumar Kartikeya Dwivedi Date: Sat, 5 Mar 2022 04:16:43 +0530 Subject: compiler_types.h: Add unified __diag_ignore_all for GCC/LLVM Add a __diag_ignore_all macro, to ignore warnings for both GCC and LLVM, without having to specify the compiler type and version. By default, GCC 8 and clang 11 are used. This will be used by bpf subsystem to ignore -Wmissing-prototypes warning for functions that are meant to be global functions so that they are in vmlinux BTF, but don't have a prototype.
