@ -248,3 +248,9 @@ Make use of hi register variants of cmp: tCMPhir / tCMPZhir.
Thumb1 immediate field sometimes keep pre-scaled values. See
Thumb1RegisterInfo::eliminateFrameIndex. This is inconsistent from ARM and
Thumb2.

add a target specific ALIGN instruction instead. That way, GetInstSizeInBytes
won't have to over-estimate. It can also be used for loop alignment pass.
