[PATCH] D83518: IR: Define byref attribute

[Matt Arsenault via Phabricator via llvm-commits]

arsenm created this revision.
arsenm added reviewers: rjmccall, jdoerfert, efriedma, t-tye, yaxunl, scott.linder, rnk, spatel, lebedev.ri, nlopes, fhahn, hfinkel, Anastasia.
Herald added subscribers: dexonsmith, steven_wu, hiraditya, wdng.
Herald added a project: LLVM.

This includes the base IR changes, and some tests for places where it
should be treated similarly to byval. Codegen support will be in a
future patch.

      

This implements the variant only capturing the size, unlike the type
in the original RFC. This also does not mandate the align attribute be
present. If the align attribute is not present, an alignment of 1 is
assumed.
