Subject: [pushed] [gdb/testsuite] Fix gdb.gdb/python-helper.exp with -O2 -flto=auto and gcc 7.5.0 some more
Date: Wed, 26 Jul 2023 13:28:31 +0200 [thread overview]
Message-ID: <20230726112831.30904-1-tdevries@suse.de> (raw)
With a gdb build with -O2 -flto=auto and gcc 7.5.0 and test-case
gdb.gdb/python-helper.exp I run into:
...
(outer-gdb) continue^M
Continuing.^M
print 1^M
^M
Thread 1 "xgdb" hit Breakpoint 2, \
_Z11value_printP5valueP7ui_filePK19value_print_options (val=0x22e2590, \
stream=0x1f65480, options=0x7fffffffcdc0) at gdb/valprint.c:1193^M
1193 {^M
(outer-gdb) FAIL: gdb.gdb/python-helper.exp: hit breakpoint in outer gdb
...
This is the "value_print" variant of the problem with "c_print_type" I fixed
in commit 0d332f11122 ("[gdb/testsuite] Fix gdb.gdb/python-helper.exp with -O2
-flto=auto and gcc 7.5.0").
Fix this likewise.
Tested on x86_64-linux.
