Bug ID: 52450
Summary: Support P1689 dependency format
Product: clang
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++2a
Assignee: unassignedclangbugs at nondot.org
Reporter: bugzilla.llvm at me.benboeckel.net

Clang should support the P1689 dependency format for modules:
https://wg21.link/p1689
I have a patch to GCC
(https://github.com/mathstuf/cxx-modules-sandbox/blob/docker/trtbd.diff) to
submit that uses the following command line flags:
`-fdep-format=` The format to write dependency information out in. Currently,
it uses `trtbd` which stands for "TR to be determined", but bikeshedding needs
to commence at some point I suppose. Ideas: `p1689`, `tr2222` (the SG15 TR
reserved number).
`-fdep-output=` is the name of the primary output for the future compilation
(the `-o` the real compile will see). This is analogous to `-MT`.
`-fdep-file=` is the file to write the information to.
