Ah, yes, we actually do have 26-bit ranges that are relevant on AArch64: direct branches have a range of +/- 128MiB (2^26, times 4 because of PC alignment, signed). A function size up to 128MiB plus epsilon (144MiB, to pick a round number?) would I think give sufficient coverage.

(And x86-64 does have 2GiB ranges for all branches and RIP-relative labels, but we actually don't have façades to extend those; we just don't support a single function body that large!)

Sounds reasonable! I've bumped the per-function limit to 150M and reduced the maximum number of functions to 5 to keep the overhead under 1G here
