[PATCH] D72701: [Hexagon] Add support for Linux/Musl ABI.

[Sid Manning via Phabricator via llvm-commits]

sidneym updated this revision to Diff 238816.
sidneym retitled this revision from "[Hexagon] Add support for Linux ABI." to "[Hexagon] Add support for Linux/Musl ABI.".
sidneym added a comment.

Update code to check for the Musl environment.

Checking OS was too vague and could result in this ABI being unexpectedly enabled if the triple was not set and the host tools were built for Linux.  Musl is the only C-library currently used by Hexagon Linux so
that is the check I'm using to enable the ABI.
