Changed paths: A JSTests/wasm/stress/foldable-division.js M Source/JavaScriptCore/wasm/WasmBBQJIT.cpp Log Message: ----------- WasmBBQJIT performs redundant overflow check when dividend is constant https://bugs.webkit.org/show_bug.cgi?id=254710 rdar://106823148 Reviewed by Yusuke Suzuki. Always skip the integer division overflow check (specifically for the case INT_MIN / -1) in WasmBBQJIT when the left operand is a constant. This reduces the amount of unnecessary work checking for erroneous divisions, and also allows the general case to assume neither operand is a constant when emitting the check. * JSTests/wasm/stress/foldable-division.js: Added. (async test): * Source/JavaScriptCore/wasm/WasmBBQJIT.cpp: (JSC::Wasm::BBQJIT::emitModOrDiv): Canonical link: https://commits.webkit.org/262335@main _______________________________________________ webkit-changes mailing list webkit-changes@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-changes
