This primarily parses a different set of options and invokes the same resource compiler as llvm-rc normally. Additionally, it can convert directly to an object file (which in MSVC style setups is done with the separate cvtres tool, or by the linker). (GNU windres also supports other conversions; from coff object file back to .res, and from .res or object file back to .rc form; that's not yet implemented.) The other bigger complication lies in being able to imply or pass the intended target triple, to let clang find the corresponding mingw sysroot for finding include files, and for specifying the default output object machine format. It can be implied from the tool triple prefix, like `<triple>-[llvm-]windres` or picked up from the windres option e.g. `-F pe-x86-64`. In GNU windres, that option takes BFD style format names such as pe-i386 or pe-x86-64. As libbfd in binutils doesn't support Windows on ARM, there's no such canonical name for the ARM targets. Therefore, as an LLVM specific extension, this option is extended to allow passing full triples, too. Differential Revision: https://reviews.llvm.org/D100756
