Bug ID: 38966
Summary: Make lld-link not depend on mt.exe on Windows
Product: lld
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: COFF
Assignee: unassignedb...@nondot.org
Reporter: nicolaswe...@gmx.de
CC: llvm-bugs@lists.llvm.org
On non-Windows, we use libxml2 and llvm/lib/WindowsManifest/ to merge
manifests.
On Windows, libxml2 usually doesn't exist, so we rely on mt.exe being on PATH.
The way forward is probably to use msxml on Windows instead of libxml2, since
that's always around. I have prototyped this a bit at
https://reviews.llvm.org/D42910 but it's incomplete.
Once this is done, lld-link.exe no longer relies on PATH and the only env var
it relies on is LIB, which can be passed via /libpath:. So once this is done,
no special env needs to be set to be able to run lld-link -- once we have this,
we can stop running lld-link.exe under `ninja -t msvc` in the chrome/win build
on win hosts. (We already don't need it on non-win hosts.)
