From 479d684ba53e70fe39d002482a00ae007a3d64cd Mon Sep 17 00:00:00 2001 From: Nikita Popov Date: Fri, 4 Mar 2022 13:25:05 +0100 Subject: [PATCH] [Coroutines] Support opaque pointers in solveTypeName() As far as I can tell, these names are only intended to be informative, so just use a generic "PointerType" for opaque pointers. The code in solveDIType() also treats pointers as basic types (and does not try to encode the pointed-to type further), so I believe this should be fine.
