Correct way to pass int128 from LLVM to C++ function (MSVC)
...tly in memory.
Until LLVM is fixed, you can work around the problem by passing i128 by
pointer, which you're probably already doing. Given that we will ultimately
pass it by pointer in order to obey the ABI, it's a pretty reasonable
workaround.

[LLVMdev] Passing structures as pointers, MSVC x64 style
The MS x64 ABI calling convention (http://msdn.microsoft.com/en-us/library/ms235286(VS.80).aspx) says:
Any argument that doesn’t fit in 8 bytes, or is not 1, 2, 4, or 8 bytes, must be passed by reference.
Clang isn't doing that for us when passing our triple, x86_64-pc-win32-macho.
Here's a simple example program:
struct Guid {
unsigned int Data1;...

Correct way to pass int128 from LLVM to C++ function (MSVC)
Hi,
I've been attempting to call a C++ function from LLVM code. The LLVM code is JIT'ted and executed from C++. Basically my idea was as follows:
-- LLVM IR code -
; ModuleID = 'native'
define i32 @main(i32, i8**) {
code:
call void @"Helper::Test"(i128 128932)
ret i32 0
-- C++ code -
struct int128
{
uint64_t v1;
uint64_t v2;
// ... code omitted... *1

It was my workaround, sorry.
Please check to tweak the clause (128 to 64) and lemme know.
