From ca43e66033ca0d72bb93837c9b1ab482977e06e6 Mon Sep 17 00:00:00 2001 From: Tankut Baris Aktemur Date: Fri, 21 May 2021 17:20:53 +0200 Subject: [PATCH] testsuite/gdb.dwarf2: avoid dead code in dw2-inline-with-lexical-scope.c The test in gdb.dwarf2/dw2-inline-with-lexical-scope.c fails with icc. The reason is, icc did not emit code for a dead statement, which in turn caused some labels to be collapsed. Fix this by replacing the dead code with assignment to a global value. The statement itself does not change the test scenario. Also fix a whitespacing problem around an assignment operator. gdb/testsuite/ChangeLog: 2021-05-21 Tankut Baris Aktemur * gdb.dwarf2/dw2-inline-with-lexical-scope.c (func): Replace a dead code with an assignment to a global var.
