Subject: [PATCH 2/3] perf build: Apply EXTRA_CXXFLAGS to C++ builds
Date: Wed,  8 Jul 2026 00:56:05 -0400	[thread overview]
Message-ID: <20260708045606.43649-3-tallison@redhat.com> (raw)
In-Reply-To: <20260708045606.43649-1-tallison@redhat.com>

C++ sources did not receive EXTRA_CXXFLAGS or EXTRA_CFLAGS, unlike C
sources. Initialize CXXFLAGS from both so C++ objects such as
demangle-cxx.o get the same builder flags as the rest of perf.
