commit ea59b70a8418a313d6f2ab48a957de015fc33018
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Wed Jul 31 11:58:56 2024 -0300
perf bpf: Move BPF disassembly routines to separate file to avoid clash with capstone bpf headers
There is a clash of the libbpf and capstone libraries, that ends up
with:
In file included from /usr/include/capstone/capstone.h:325,
from util/disasm.c:1513:
/usr/include/capstone/bpf.h:94:14: error: bpf_insn defined as wrong kind of tag
94 | typedef enum bpf_insn {
So far we're just trying to avoid this by not having both headers
included in the same .c or .h file, do it one more time by moving the
BPF diassembly routines from util/disasm.c to util/disasm_bpf.c.
This is only being hit when building with BUILD_NONDISTRO=1, i.e.
building with binutils-devel, that isn't the in the default build due to
a licencing clash. We need to reimplement what is now isolated in
util/disasm_bpf.c using some other library to have BPF annotation
feature that now only is available with BUILD_NONDISTRO=1.
