From: Alexandre Oliva <aoliva@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/users/aoliva/heads/testme)] untyped calls: use wrapper class type for implicit plus_one Date: Fri, 1 Dec 2023 18:04:47 +0000 (GMT) [thread overview] Message-ID: <20231201180447.4CD583861865@sourceware.org> (raw) https://gcc.gnu.org/g:03486b004e5fdf7c62c3bf5c20175b1334afedc0 commit 03486b004e5fdf7c62c3bf5c20175b1334afedc0 Author: Alexandre Oliva <oliva@adacore.com> Date: Fri Dec 1 10:28:19 2023 -0300 untyped calls: use wrapper class type for implicit plus_one Instead of get and set macros to apply a delta, use a single macro that resorts to a temporary wrapper class to apply it. To be combined (or not) with the previous patch.
