From 61fba2674fb10a8b8b2ae6b5ec965fd1fd738395 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Fri, 12 Jul 2019 18:38:33 +0000 Subject: [PATCH] [Darwin, testsuite] Remove unused test. During GCC-9, the codegen for unreachable switch case statements changed such that the (undefined) behaviour of reaching such statements is directed to one of the existing switch cases. This means that the testcase which deals with the old behaviour can no longer work (and there is nothing to test with it). The [Darwin-specific] test is now redundant and can be removed. gcc/testsuite/ 2019-07-12 Iain Sandoe * gcc.dg/pr57438-2.c: Remove.
