Even if calleedoesn't have these parameters, the invocation succeed ignoring extraparameters.But WebAssembly strictly checks that callee and caller signatures aresame. https://github.com/WebAssembly/design/blob/master/Semantics.md#callsSo at WebAssembly level, all swiftcc functions end up extra argumentsand all function definitions and invocations explicitly have additionalparameters to fill swifterror and swiftself.This patch support signature difference for swiftself and swifterror ccis swiftcc.e.g.```declare swiftcc void @foo(i32, i32)@data = global i8* bitcast (void (i32, i32)* @foo to i8*)define swiftcc void @bar() { %1 = load i8*, i8** @data %2 = bitcast i8* %1 to void (i32, i32, i32)* call swiftcc void %2(i32 1, i32 2, i32 swiftself 3) ret void}```For swiftcc, emit additional swiftself and swifterror parametersif there aren't while lowering. These additional parameters are addedfor both callee and caller.They are necessary to match callee and caller signature for direct andindirect function call.Differential Revision: https://reviews.llvm.org/D76049 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/WebAssembly/swiftcc.ll Fri, 20 Mar 2020 00:39:34 +0000 Yuta Saito <kateinoigakukun@gmail.com>
