[PATCH] D114946: [AArch64] Add instruction selection for strict FP

[John Brawn via Phabricator via llvm-commits]

john.brawn added a comment.

It turns out that though global isel is enabled at -O0 it also falls back to non-global isel when it sees things it can't handle, and there's several things unrelated to strict fp (or that are but aren't aarch64-specific) that cause this to happen. I've added the a run line to run the test with -global-isel=true anyway, but with the option that means we get this fallback behaviour. I'll post some follow-on patches later to fix some of these global isel things.
