Comment on attachment 219503 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=219503&action=review r=me > Source/JavaScriptCore/ChangeLog:11 > + Add an explicit abstraction for the "lea" instruction. This is needed > + by the experimental JIT to have add and substract without changing the flags. Why do we need to avoid changing flags before a call? Would be good to explain that. > Source/JavaScriptCore/assembler/MacroAssemblerX86_64.h:231 > +#if ENABLE(CSS_SELECTOR_JIT) No need for the #if. > Source/WebCore/cssjit/StackAllocator.h:112 > + void combine(StackAllocator&& stackA, StackAllocator&& stackB) I think the typical compiler word for this is "merge".
