[PATCH 02/16] Eliminate literal line numbers in dbx.exp
- From: Andreas Arnez <arnez at linux dot vnet dot ibm dot com>
- To: gdb-patches at sourceware dot org
- Date: Wed, 29 Oct 2014 17:00:17 +0100
- Subject: [PATCH 02/16] Eliminate literal line numbers in dbx.exp
- Authentication-results: sourceware.org; auth=none
- References: <1414597859-12523-1-git-send-email-arnez at linux dot vnet dot ibm dot com>
Remove literal line numbers from the commands and regexps in dbx.exp.
Add appropriate eye-catchers to average.c and sum.c and refer to those
instead.
gdb/testsuite/ChangeLog:
* gdb.base/average.c: Add eye-catchers.
* gdb.base/sum.c: Likewise.
* gdb.base/dbx.exp: Use eye-catchers to determine line numbers for
regexps dynamically.
