The spec tests try to validate NaNs are handled properly and compare their values. The bug could be: - In our code - In the spec tests (they're not currently up to date, see https://github.com/WebAssembly/spec/pull/414) - In the code that translates .wast -> .wast.js This is unlikely to be important for the near future, so I'll ignore it for now. Maybe we can just comment out the "assert_[0-9]+" invocations for now, and revisit when we update the tests. 1304073 3 webkit-bug-importer 2017-05-03 09:54:34 -0700 <rdar://problem/31965311> 1710309 4 chi187 2020-11-27 08:50:43 -0800 I think that this issue is not valid anymore 1719307 5 yegor.jbanov 2021-01-13 09:14:12 -0800 We're seeing this error occasionally, specifically: Error: Unreachable code should not be executed (evaluating 'invoker(fn, thisWired)') We run on: LastOSVersionSafariWasLaunchedOn = "10.15.7"; NewestLaunchedSafariVersion = "609.4.1"; Is there something Emscripten could do to work around the issue? 1719308 6 yegor.jbanov 2021-01-13 09:14:58 -0800 Full log: https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket.appspot.com/8858212739179103328/+/steps/felt_test_safari_desktop/0/stdout 1719378 7 ysuzuki 2021-01-13 11:59:25 -0800 (In reply to Yegor from comment #6) > Full log: > https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket.appspot. > com/8858212739179103328/+/steps/felt_test_safari_desktop/0/stdout I don't think this error is related to f32.wast.js. Please open a new bug. And please attach a test case which can reproduce this :)
