Subject: [PATCH] perf loongarch: Fix build failure with CONFIG_LIBDW_DWARF_UNWIND
Date: Tue, 14 Apr 2026 08:51:52 +0800	[thread overview]
Message-ID: <20260414005152.10550-1-r@hev.cc> (raw)

Building perf for LoongArch fails when CONFIG_LIBDW_DWARF_UNWIND is
enabled because unwind-libdw.o is still referenced in
arch/loongarch/util/Build.

Fixes: e62fae9d9e8 ("perf unwind-libdw: Fix a cross-arch unwinding bug")
Signed-off-by: WANG Rui <r@hev.cc>
