[PATCH] D125648: [ARM SEH 6] [ARM] Add SEH opcodes in frame lowering

[Martin Storsjö via Phabricator via llvm-commits]

mstorsjo updated this revision to Diff 433506.
mstorsjo added a comment.

Skip Thumb2SizeReduction for SEH prologs/epilogs, and force tail calls to wide instructions (just like on MachO), to make sure that the unwind info actually matches the width of the final instructions without heuristics about what later passes will do.
