+Subject: [PATCH] Detect 32-bits armv8-a architecture
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+Adds WTF platform support for the 32-bits armv8-a architectures.
+
+Theses toolchains define __ARM_ARCH_8A__ (for ARM architecture version)
+and __arm__ (for 32-bits word-size; __aarch64__ for 64-bits).
+
+This commit catches this new architecture (armv8a) within a #ifdef/#endif
+inside the if statement dedicated for 32-bits ARM detection.
+
+Fixes:
+
+	In file included from ./config.h:30:0,
+	                 from ...
+	./wtf/Platform.h:323:6: error: #error "Not supported ARM architecture"
+	 #    error "Not supported ARM architecture"
+	      ^~~~~
+
+Upstream-Status: Backport [with adaptations]
