ARM: 9062/1: kprobes: rewrite test-arm.c in UAL
Clang's integrated assembler only accepts UAL syntax, rewrite the
instructions that were changed by RVCTv2.1. The document "Assembly
language changes after RVCTv2.1" was very helpful.
.syntax unified
directive is added, since -masm-syntax-unified is unreliable for older
but supported versions of GCC. See also:
