Bug 1592974 - Spill registers before emitting an interrupt check
47 bytes, text/x-phabricator-request
Details | Review

Interrupt checks, added to the WebAssembly baseline compiler output in loops, assume there are no registers live. However with loop parameters under the multi-value proposal, it's possible there are registers coming into a loop, so we need to sync.
