[gdb/testsuite] Add missing initial prompt read in multidictionary.exp
|
|
|
|
When running multidictionary.exp in conjunction with:
|
|
...
|
|
$ stress -c $(($(cat /proc/cpuinfo | grep -c "^processor") + 1))
|
|
...
|
|
we get:
|
|
...
|
|
Running gdb/testsuite/gdb.dwarf2/multidictionary.exp ...
|
|
ERROR: Couldn't load multidictionary into gdb.
|
|
|

=== gdb Summary ===

|
|
nr of unresolved testcases 1
|
|
...
|
|
|
|
The multidictionary test-case needs -readnow, and achieves this using:
|
|
...
|
|
gdb_spawn_with_cmdline_opts "-readnow"
|
|
gdb_load
|
|
...
|
|
but the initial gdb prompt is not read. Usually, the following gdb_load
|
|
command accidentally consumes that initial prompt (at the gdb_expect for the
|
|
kill command in gdb_file_cmd). But under high load, that doesn't happen and
|
|
we run into the error.
|
|
|
|
Fix this by consuming the initial gdb prompt after spawning gdb.
|
|
|
|
Tested on x86_64-linux.
