[LLVMdev] [PATCH] Apply Thumb2 ROR optimization only when Thumb2 is supported
I went ahead and committed it, along with a basic test case, in svn r159538.

[LLVMdev] [PATCH] Apply Thumb2 ROR optimization only when Thumb2 is supported
Hi Matt,
You're absolutely right, that pattern should definitely have an "only-in-Thumb2" predicate attached.
Do you have commit access? Also, if you have a reduced test case, that would be awesome, but the patch is correct as-is even if not.

[LLVMdev] [PATCH] Apply Thumb2 ROR optimization only when Thumb2 is supported
I've been playing around with using LLVM on one of our projects, which
runs on an arm1176jzf-s processor. When compiling for Thumb, a couple
of the generated assembly files end up with a 'ror.w' instruction,
which is a Thumb2 instruction. Since arm1176jzf-s doesn't support
Thumb2, the assembler then turns around and barfs on it.
I don't have any experience with this
