[PATCH] D125094: [ARM][Thumb] Command-line option to ensure AAPCS compliant Frame Records

[Lucas Prates via Phabricator via llvm-commits]

pratlucas added a comment.

The newly added `frame-chain.ll` test uncovered an issue with an invalid use of the tMOVr instruction, which is only available from V6 onwards. The failure was captured by a buildbot with expensive checks enabled.
The issue is unrelated to the codegen changes from this patch, and still happens when compiling the same IR code if the changes are reverted.
Given the above, I've updated the test to use thumbv6m while the issue is not resolved: rGcbcce82ef6b5 <https://reviews.llvm.org/rGcbcce82ef6b512d97e92a319a75a03e997c844e1>.
