<div>
<pre>At the moment "link.exe" is hard-coded as default linker in MSVC.cpp,
so there's no way to use LLD as default linker for MSVC driver.
For Windows on Arm this is a release blocker because link.exe is an x86_64
binary, which WoA can't emulate (only x86_32 emulation is supported), so
linking fails unless -fuse-ld=lld option is provided.
This is fixed on trunk in <a href="https://reviews.llvm.org/D98493">https://reviews.llvm.org/D98493</a>, but needs
backporting to releases/12.x .</pre>
