I think that we don't want to introduce differences like that. Ideally, we
should be able to mix tools with crt builds with another tools (so, for
example, use crt built with GCC with clang+lld and the other way around).
Martin in other email pointed that there are such differences due to
llvm's dlltool is different from binutils's dlltool (usage of short vs
long imports and non-usage of weak symbols). So as I understood, mixing
is currently not possible.
This is not true, it's very much possible to mix tools freely.
In a regular setup with GCC/binutils, you can easily build individual
object files with Clang instead of GCC. And you can link with LLD instead
of GNU ld by using -fuse-ld=lld. This works, LLD can link against both
short and long import libraries just fine, even if short ones is the
native (and corner case features like delayloading works differentbly
between the two).
The opposite also works, but to a lesser degree; GNU ld does support
linking against short import libraries in general, but it fails on
handling the weak externals that are used for aliases in our base CRT
import libraries.
