calling va_arg functions on win32 seems to require explicit stack alignment?
target datalayout = "e-m:x-p:32:32-i64:64-f80:32-n8:16:32-a:0:32-S32"
target triple = "i686-pc-windows-msvc"
declare void @llvm.va_start(i8**)
declare void @llvm.va_end(i8**)
define i64 @foo(...) {
%va = alloca i8*, i32 16 ; 4 words should be enough?
call void @llvm.va_start(i8** %va)
%x = va_arg i8** %va, i64
call void @llvm.va_end(i8** %va)
ret i64 %x
}
