--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:903c18c65c4eb135eb3c67a3c14fb6c20f537feb commit r10-10807-g903c18c65c4eb135eb3c67a3c14fb6c20f537feb Author: Iain Sandoe <i...@sandoe.co.uk> Date: Mon Aug 16 21:22:13 2021 +0100 Objective-C, NeXT: Fix messenging non-aggregate return-in-memory. When a method returns a type that the platform ABI says should be returned in memory, and that is done by a hidden 'sret' parameter, the message send calls must be adjusted to inform the runtime that the sret parameter is present. As reported in the PR, this is not working for non-aggregate types that use this mechanism. The fix here is to adjust the logic such that all return values that flag 'in memory' are considered to use the mechanism *unless* they provide a struct_value_rtx *and* the return object is an aggregate.
