From 478dd60ddcf17773ebd1af367c9dcaee2401f797 Mon Sep 17 00:00:00 2001 From: David Malcolm Date: Thu, 15 Nov 2018 14:32:41 +0000 Subject: [PATCH] Machine-readable diagnostic output (PR other/19165) This patch implements a -fdiagnostics-format=json option which converts the diagnostics to be output to stderr in a JSON format; see the documentation in invoke.texi. Logically-related diagnostics are nested at the JSON level, using the auto_diagnostic_group mechanism. gcc/ChangeLog: PR other/19165 * Makefile.in (OBJS): Move json.o to...
