Wasmtime GitHub notifications bot (Jun 09 2020 at 23:56): Wasmtime GitHub notifications bot (Jun 09 2020 at 23:56):cfallin opened PR #1852 from reftypes to master:
This PR adds the inital support to allow reftypes to flow through the
program when targetting aarch64. It also adds a fix to the
ModuleTranslationStateneeded to send R32/R64 types over from the
SpiderMonkey embedding.This PR does not include any support for safepoints in aarch64 or the
MachInstinfrastructure. That work will come as a second PR, following
some needed changes to regalloc.rs.This PR also makes a drive-by improvement to
Bint, avoiding an
unneeded zero-extension op when the extended value comes directly from a
conditional-set (which produces a full-width 0 or 1).With this PR, and a companion patch in SpiderMonkey, we're able to make it
through all of the reftypes tests in the spec testsuite, though we aren't emitting
stackmaps yet so if the GC had been triggered we would have been in trouble.
Still, it's a start!<!--

It's actually
cmn, which is a separate instruction. It compares against the twos-complement value of the RHS. We wantcmp rn, #-1but-1can't be encoded in anImm12, so the idiomatic approach on AArch64 is to docmn rn, #-1.
