From 01b2864757540d24c4e717a77b40b29369c064b2 Mon Sep 17 00:00:00 2001 From: Jason Merrill Date: Tue, 18 May 2021 17:15:42 -0400 Subject: c++: ICE with bad definition of decimal32 [PR100261] The change to only look at the global binding for non-classes meant that here, when dealing with decimal32 which is magically mangled like its first non-static data member, we got a collision with the mangling for float. Fixed by also looking up an existing binding for such magical classes.
