[PATCH] D32564: AArch64: compress jump tables to minimum size needed to reach destinations

[Tim Northover via Phabricator via llvm-commits]

t.p.northover updated this revision to Diff 166652.
t.p.northover added a comment.

Tidy-ups suggested by JF, and (also JF's idea) switch to an offset from the lowest-addressed basic-block instead of the actual branch to increase the number of candidates.
