From 9f53b76775c53998a7714570ae8d36acab02a07f Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Fri, 15 Feb 2019 08:52:50 +0100 Subject: [PATCH] re PR other/69006 (Extraneous newline emitted between error messages in GCC 6) PR other/69006 PR testsuite/88920 * lib/gcc-dg.exp: If llvm_binutils effective target, set allow_blank_lines to 2 during initialization. (dg-allow-blank-lines-in-output): Set allow_blank_lines to 1 only if it was previously zero. (gcc-dg-prune): Don't check for llvm_binutils effective target here. Clear allow_blank_lines afterwards whenever it was 1. * gdc.test/gdc-test.exp (dmd2dg): Don't call dg-allow-blank-lines-in-output here. (gdc-do-test): Set allow_blank_lines to 3 if it is 0 before running the tests and restore it back at the end.
