--- Comment #18 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- Author: aoliva Date: Thu Jul 18 00:38:45 2019 New Revision: 273563 URL: https://gcc.gnu.org/viewcvs?rev=273563&root=gcc&view=rev Log: -Wmissing-attributes: check that we avoid duplicates and false positives The initial patch for PR 81824 fixed various possibilities of -Wmissing-attributes reporting duplicates and false positives. The test that avoided them was a little obscure, though, so this patch rewrites it into a more self-evident form. The patch also adds a testcase that already passed, but that explicitly covers some of the possibilities of reporting duplicates and false positives that preexisting tests did not cover. for gcc/ChangeLog PR middle-end/81824 * attribs.c (decls_mismatched_attributes): Simplify the logic that avoids duplicates and false positives. for gcc/testsuite/ChangeLog PR middle-end/81824 * g++.dg/Wmissing-attributes-1.C: New.
