[cfe-dev] LLD for ARM

[Daniel Dilts]

Right now I am working a proof of concept at work that I can use Clang and
associated tools to compile for a bare metal ARM processor (Beaglebone
Black).  The biggest issue seems to be that we develop on Windows and most
cross linkers (ld, gold) seem to only want to work on POSIX, which is not
Windows.  So far I have spent a day fighting binutils to get ld to compile
on Windows to target ARM.

For a complete novice, what would be the expected amount of effort (days,
weeks, months, years) to add support for a new target?
