| |
The samples/bpf reuses linux headers, with clang -emit-llvm, so this w/a is only for samples/bpf (samples/bpf/Makefile CLANG-bpf).
It allows to build samples/bpf for arm on target board. In another way clang -emit-llvm generates errors like:
<inline asm>:1:1: error: unknown directive .syntax unified
I have verified it on clang 5, 6 ,7, 8, 9, 10 as on native platform as for cross-compiling. This decision is arguable, but it doesn't have impact on samples/bpf so it's easier just ignore it for clang, at least for now...
