Comment on attachment 294773 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=294773&action=review > Source/JavaScriptCore/wasm/WasmFunctionParser.h:202 > + if (!popExpressionStack(condition)) This is last: select: a ternary operator with two operands, which have the same type as each other, plus a boolean (i32) condition. select returns the first operand if the condition operand is non-zero, or the second otherwise. I think the values are inverted as well.

I think it's right the condition is the last thing pushed to the stack and so it's the first thing popped off the stack in select.
