Is there a way to use LLC to cross-compile some code to run on Windows IOT on Raspberry Pi ? I was able to convince LLVM to spit out some bitcode for this, but when I try llc it dumps:

llc.exe test.bc -o test.obj -filetype=obj -O3 -mtriple=aarch64-win32-msvc -mcpu=cortex-a53

Windows 10 IoT on Raspberry Pi (or anywhere else) is just 32 bit arm for now, so you want to try the armv7-win32-msvc target triplet instead.

(There is some preliminary support for aarch64-win32 targets also; it seems to work for C code for things I've tested so far, but e.g. C++ support is incomplete. And there's no public aarch64 windows version out at all yet, it's supposedly coming late this year though. So far I've been testing it with wine.)
