[LLVMdev] Intrinsic prototype has incorrect number of arguments!
Hello, I have a question, what is wrong with the following code? declare void @llvm.memcpy.p0i64.p0i64.i8(i64*, i64*, i8, i32, i1) nounwind ... call void @llvm.memcpy.p0i64.p0i64.i8(i64* %19, i64* %21, i8 %17, i32 0, i1 false) ... According to the compiler this is the error, but I seem to miss where exactly my fault is. Intrinsic prototype has incorrect number of arguments! void (i64*, i64*, i8, i32, i1)* @llvm.memcpy.p0i64.p0i64.i8 Any help would be appreciated.

I don't know that your prototype is correct. What's the corresponding code? Can you send the module on and whatever you did to construct it? -eric

[LLVMdev] Intrinsic prototype has incorrect number of arguments!
I have created the function prototype with the following code: const uintmax_t methodNameSize = 1024; const char methodNameTemplate[] = "llvm.memcpy.p0i%llu.p0i%llu.i%llu"; char methodName[methodNameSize]; // Create the methodName. memset(methodName, 0, methodNameSize); sprintf(methodName, methodNameTemplate, dstSize, srcSize, lengthSize); // Search for the function or create it. if((function = LLVMGetNamedFunction(module, methodName)) == NULL) { LLVMTypeRef paramTypes [] = { dstType, srcType, lengthType, LLVMInt32TypeInContext(context), LLVMInt1TypeInContext(context), }; functionType = LLVMFunctionType(LLVMVoidTypeInContext(context), paramTypes, numberOfArguments, false); function = LLVMAddFunction(module, methodName, functionType); LLVMRemoveAttribute(LLVMGetParam(function, 0), LLVMNoCaptureAttribute); LLVMRemoveAttribute(LLVMGetParam(function, 1), LLVMNoCaptureAttribute); } And then invoked it with this: LLVMValueRef args[] = { sourcePtr, destinationPtr, lengthInteger, LLVMConstInt(LLVMInt32TypeInContext(context), 0, true), LLVMConstInt(LLVMInt1TypeInContext(context), (unsigned long long)false, true), }; LLVMBuildCall(builder, function, args, numberOfArguments, ""); Then you end up with the following prototype: declare void @llvm.memcpy.p0i64.p0i64.i64(i64*, i64*, i64, i32, i1) nounwind and this code will invoke the copy: reallocBlock: ; preds = %entry %5 = getelementptr inbounds %0* %0, i32 0, i32 2 ; <i64*> [#uses=1] %6 = load i64* %5 ; <i64> [#uses=1] %7 = add i64 %6, 25 ; <i64> [#uses=2] %8 = getelementptr inbounds %0* %0, i32 0, i32 0 ; <i64**> [#uses=1] %9 = load i64** %8 ; <i64*> [#uses=1] %10 = trunc i64 %7 to i32 ; <i32> [#uses=1] %mallocsize = mul i32 %10, ptrtoint (i64* getelementptr (i64* null, i32 1) to i32) ; <i32> [#uses=1] %malloccall = tail call i8* @malloc(i32 %mallocsize) ; <i8*> [#uses=1] %11 = bitcast i8* %malloccall to i64* ; <i64*> [#uses=1] call void @llvm.memcpy.p0i64.p0i64.i64(i64* %9, i64* %11, i64 %7, i32 0, i1 false) br label %exit Any ideas on what I am doing wrong here ?

No it shouldn't be, the LLVM assembly language reference manual declares it at follows: declare void @llvm.memcpy.p0i8.p0i8.i32(i8* <dest>, i8* <src>, i32 <len>, i32 <align>, i1 <isvolatile>) On 07 Sep 2010, at 20:38, Bill Wendling wrote:> > On Sep 7, 2010, at 8:03 AM, F van der Meeren wrote: > >> Hello, >> >> I have a question, what is wrong with the following code? >> >> declare void @llvm.memcpy.p0i64.p0i64.i8(i64*, i64*, i8, i32, i1) nounwind >> >> ... >> >> call void @llvm.memcpy.p0i64.p0i64.i8(i64* %19, i64* %21, i8 %17, i32 0, i1 false) >> >> ... >> >> >> According to the compiler this is the error, but I seem to miss where exactly my fault is. >> >> Intrinsic prototype has incorrect number of arguments! >> void (i64*, i64*, i8, i32, i1)* @llvm.memcpy.p0i64.p0i64.i8 >> >> Any help would be appreciated. >> > The third parameter should be a pointer. > > -bw >-------------- next part -------------- An HTML attachment was scrubbed...
