GopherJS breaks lhs expression evaluation order defined by the spec. Unfortunately, it's not easy to fix and would likely generate a lot more code for multi-assignments. An efficient fix would require writing some sort of analysis to determine if assignments are likely to influence each other, and at the moment I can't think of how such analysis would work. Without it we would have to create a whole bunch of extra temporary variables for any multi-assignment, which will likely lead to a significant increase in the artifact size. Considering nobody reported this issue so far, I'm inclined to punt on this issue for now. https://github.com/gopherjs/gopherjs/issues/1063 tracks this bug. --- tests/gorepo/run.go | 1 + 1 file changed, 1 insertion(+) diff --git a/tests/gorepo/run.go b/tests/gorepo/run.go index 6dfea3675..f82e240c7 100644 --- a/tests/gorepo/run.go +++ b/tests/gorepo/run.go @@ -147,6 +147,7 @@ var knownFails = map[string]failReason{ "fixedbugs/issue5493.go": {category: notApplicable, desc: "GC related, not relevant to GopherJS"}, "fixedbugs/issue46725.go": {category: notApplicable, desc: "GC related, not relevant to GopherJS"}, "fixedbugs/issue43444.go": {category: lowLevelRuntimeDifference, desc: "GopherJS println format is different from Go's"}, + "fixedbugs/issue23017.go": {desc: "https://github.com/gopherjs/gopherjs/issues/1063"}, } type failCategory uint8
