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

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

For scheduling, the AArch64 backend overrides "isSchedulingBoundary()" for SEH instructions.

I don't think we ever ran into issues with tail merge... maybe setting MachineInstr:::NoMerge would work?
