Use SlowPathFrameTracer to configure topCallFrame in Wasm LLInt SlowPathes. And remove storeTopCallFrame since it is no longer used: it was originally introduced to make VM separate from Wasm::Instance etc. while keeping the functionality of setting a CallFrame* to VM. But now we wiped this abstraction, so this SlowPathFrameTracer change cleans up things. We also fix bugs of wasm GC operations where they do not set topCallFrame correctly. They need to set it since they do GC allocation, which can cause ShadowChicken processing, and it requires topCallFrame. This patch fixes them. * Source/JavaScriptCore/wasm/WasmInstance.h: (JSC::Wasm::Instance::storeTopCallFrame): Deleted. * Source/JavaScriptCore/wasm/WasmSlowPaths.cpp: (JSC::LLInt::WASM_SLOW_PATH_DECL): (JSC::LLInt::slow_path_wasm_throw_exception): Canonical link: https://commits.webkit.org/258824@main _______________________________________________ webkit-changes mailing list webkit-changes@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-changes
