From d334ae250a3ec888f0603cf8e909d0f425aeb30f Mon Sep 17 00:00:00 2001 From: Luis Machado Date: Fri, 20 Jan 2017 13:15:36 -0600 Subject: [PATCH] Make gdb.python/python.exp more robust I noticed gdb.python/python.exp failing on aarch64-elf like so: FAIL: gdb.python/python.exp: Test decode_line func1 line number This particular test expects the line number for func1 to be 19, hardcoded. In my aarch64-elf tests gdb thinks func1 is at line 20, making the test fail. The following patch addresses this by reading the line number information from GDB and comparing it against the python decoded symtab information. gdb/testsuite/ChangeLog: 2017-01-20 Luis Machado * gdb.python/python.exp: Check line number against what GDB thinks the line number is for func1. --- gdb/testsuite/ChangeLog | 5 +++++ gdb/testsuite/gdb.python/python.exp | 16 +++++++++++++++- 2 files changed, 20 insertions(+), 1 deletion(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 8a0328295dd..3af1d65b564 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,8 @@ +2017-01-20 Luis Machado + + * gdb.python/python.exp: Check line number against what GDB thinks + the line number is for func1. + 2017-01-08 Iain Buclaw * gdb.dlang/debug-expr.exp: New file. diff --git a/gdb/testsuite/gdb.python/python.exp b/gdb/testsuite/gdb.python/python.exp index 95ec74ef642..de8daadaffc 100644 --- a/gdb/testsuite/gdb.python/python.exp +++ b/gdb/testsuite/gdb.python/python.exp @@ -246,7 +246,21 @@ if { [is_remote host] } { set python_1_c [string_to_regexp "gdb.python/python-1.c"] } gdb_test "python print (symtab\[1\]\[0\].symtab)" ".*${python_1_c}" "test decode_line func1 filename" -gdb_test "python print (symtab\[1\]\[0\].line)" "19" "test decode_line func1 line number" + +# Set a default value for func1_lineno in case we fail to fetch the line number +# below. +set func1_lineno "noline" + +# Fetch the line GDB thinks func1 starts at.
