From ad172f720de079e6169897e5edada8d887560a33 Mon Sep 17 00:00:00 2001 From: Andrew Stubbs Date: Tue, 11 Sep 2018 10:26:57 +0000 Subject: [PATCH] Add sorry_at diagnostic function. The plain "sorry" diagnostic only gives the "current" location, which is typically the last line of the function or translation unit by time we get to the back end. GCN uses "sorry" to report unsupported language features, such as static constructors, so it's useful to have a "sorry_at" variant. This patch implements "sorry_at" according to the pattern of the other "at" variants. 2018-09-11 Andrew Stubbs gcc/ * diagnostic-core.h (sorry_at): New prototype. * diagnostic.c (sorry_at): New function.
