I see LLVM that looks like it's been customized for the x86-64,
versus the varargs stuff I was led to expect from the LLVM IR documentation.

[LLVMdev] Help with replacing instructions via function pass
Hi,
In my IR code, I have the following:
%arr = alloca [30 x i8], align 1
%arraydecay = getelementptr inbounds [16 x i8]* %arr, i32 0, i32 0
%arraydecay1 = getelementptr inbounds [16 x i8]* %arr, i32 0, i32 0
I'm trying to change the capacity of arr via a function pass. I've written the following code in my function pass:
ArrayType* b = ArrayType::get(IntegerType::get(getGlobalContext(), 8), 10);
AllocaInst* pa = new AllocaInst(b, "ar...
