[PATCH] D112768: [ARM] implement support for TLS register based stack protector

[Ard Biesheuvel via Phabricator via llvm-commits]

ardb updated this revision to Diff 384116.
ardb added a comment.

- add diagnostics to the frontend and asserts to the backend to ensure that the TLS stack protector is only used on target subarchs that implement the hardware TLS register to begin with
- ensure that the offset parameter is not omitted, as the default is INT_MAX which is out of bounds
