View in context: https://bugs.webkit.org/attachment.cgi?id=355436&action=review Thanks for the review. >> JSTests/wasm/regress/wasm-memory-requested-more-than-MAX_ARRAY_BUFFER_SIZE-2.js:88 >> +} > > Why not just write this as a wasm test so you're not copying part of the module builder? This test is a cleaned up version of one provided by an external contributor. I rather keep it close to its original form. Also, this "Out of memory" behavior is not required (though allowed) by the WASM spec: it is an artifact of our implementation that does not allow ArrayBuffers to be greater than MAX_ARRAY_BUFFER_SIZE in size. The bug is that we were previously throwing a RangeError or crashing on a RELEASE_ASSERT. This patch fixes it to throw an OOME instead. Since this is not spec required behavior, I don't think it's right to put it in the wasm/spec-tests directory. 1480839 5 355436 ews-watchlist 2018-11-21 15:04:40 -0800 Comment on attachment 355436 proposed patch.
