Wasmtime GitHub notifications bot (Aug 04 2020 at 23:50): Wasmtime GitHub notifications bot (Aug 04 2020 at 23:50):cfallin opened PR #2097 from fix-wasm-brtable to main:
Similar to an earlier issue for ordinary branches (fixed in PR #1833),
the cranelift-wasm crate did not previously correctly translate a
br_tableinstruction's default-target branch when the branch target was
a loop with loop parameters. The mistranslated CLIF resulted in a
validation error. This one-line fix simply fills in the correct
parameter count, generating a jump instruction with the appropriate
parameters from the stack.This issue was found by :decoder in the SpiderMonkey embedding of
Cranelift, in https://bugzilla.mozilla.org/show_bug.cgi?id=1657062. The
test case is from that bug report.<!--
