Subject: r120333 changed the opcode for the Thumb1 stuff from ARM::tMOVr to
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a68a4fdf37676794ce69624d1fd4e4627c377902;p=oota-llvm.git

r120333 changed the opcode for the Thumb1 stuff from ARM::tMOVr to
ARM::tMOVgpr2gpr. But this check didn't change. As a result, we were getting
misaligned references to the jump table from an ADR instruction.

There is a test case, but unfortunately it's sensitive to random code changes.
