From 1bb17b4c6c91ad4d9468247cf5f5464fa6440668 Mon Sep 17 00:00:00 2001 From: Spoorthy S Date: Tue, 13 Jun 2023 22:11:31 +0530 Subject: [PATCH] perf tests arm_callgraph_fp: Address shellcheck warnings about signal names and adding double quotes for expression MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Running shellcheck -S on test_arm_calligraph_fp throws warnings SC2086 and SC3049,       $shellcheck -S warning tests/shell/test_arm_callgraph_fp.sh          rm -f $PERF_DATA             : Double quote to prevent globbing and word splitting.          trap cleanup_files exit term int       : In POSIX sh, using lower/mixed case for signal names is undefined. After fixing the warnings,       $shellcheck tests/shell/test_arm_callgraph_fp.sh       $ echo $?       0 To address the POSIX shell warnings added changes to convert Lowercase signal names to uppercase in the script and double quoted the command substitutions($fix to "$fix") to solve Globbing warnings.
