+Subject: [PATCH] build-sys: meson: check if NEON code can be compiled on arm
+
+When Meson SIMD module returns HAVE_NEON=1 on arm host, do extra compile check
+to verify compiler can actually handle NEON code.
+
+Related Meson issue #6361 https://github.com/mesonbuild/meson/issues/6361
+
+Part-of: <https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/574>

+Upstream-Status: Backport[https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/commit/6d2a49a6a1eacc2096d0d9473a074421c181ab56]
