llvm dev - Sep 2016 - PtrToInt in array initializer

Hello all,

I'm trying to use the C API to initialize a global integer array with
the address of another global, but ptrtoint yields an array instead of
an integer.  You can see a short program demonstrating the issue here
(tested with LLVM 3.8.1 and 4.0.0svn-r280709 on Linux x86_64):

https://raw.githubusercontent.com/dobyrch/dbc/master/llvm_bug/example.c

Note that the use of ptrtoint in the array initializer causes all array
elements to take on the type [2 x i64] instead of i64.  If the output
is manually edited to change the element types to i64, llc compiles it
without error.

Is this a bug, or am I misunderstanding/misusing ptrtoint?

Thanks,
Doug

I think the problem is on the "LLVMConstArray" line. The first
argument is called "ElementTy" so it should probably just be TYPE_INT.

Cheers.

Thank you, I can't believe I missed that.
