+Subject: [PATCH] arm: fix build on Thumb-only architectures
+
+Building tinymembench for ARM Cortex-M currently fails, because the
+arm-neon.S file contains ARM code that doesn't build on Thumb-only
+architectures. To account for this and fix the build for Cortex-M,
+this patch adjusts the compile time condition to also verify that the
+architecture supports the ARM instruction set, by testing the
+__ARM_ARCH_ISA_ARM compiler define.

+	  Tinymembench is a simple memory benchmark program, which
+	  tries to measure the peak bandwidth of sequential memory
+	  accesses and the latency of random memory accesses.
+	  Bandwidth is measured by running different assembly code for
+	  the aligned memory blocks and attempting different prefetch
+	  strategies.
