LGTM with /// for the comments in the test.

Good point. At least one of the A's stands for Arm in any case.

Comment at: clang/test/Driver/arm-aarch64-bitfield-flags.c:2
+// check -faapcs-bitfield-width/-fno-aapcs-bitfield-width
+// RUN: %clang -target arm-arm-none-eabi -march=armv8-m.main -faapcs-bitfield-width -### %s 2>&1 | FileCheck --check-prefixes=WIDTH,INVERSE-WIDTH %s
+// RUN: %clang -target aarch64-arm-none-eabi -march=armv8-m.main -faapcs-bitfield-width -### %s 2>&1 | FileCheck --check-prefixes=WIDTH,INVERSE-WIDTH %s
----------------
Nit: Use /// for comments that aren't run/check lines.
