[ARM] Support for ARMv6-Z / ARMv6-ZK missing

Authored by tyomitch on Sep 29 2015, 2:34 AM.



As @richard.barton.arm observed at TargetParser in LLVM has insufficient support for ARMv6Z and ARMv6ZK.

In particular, there were no tests for TrustZone being supported in these architectures.

The patch clears a FIXME: left by @compnerd in r201471, and fixes his test case which hadn't really been testing what it was claiming to test.

This seems in conflict with the line above.

Quite the opposite: this is to check that only one "error: instruction requires: TrustZone" is emitted.

As this test case doesn't use labels, the line above may otherwise match an error emitted from the first part of the test.

Ah, right. Can we get away with a CHECK-V7-NEXT-NOT? Either way, the patch looks fine.
