gdb.base/gnu_vector.exp: Don't test output from the inferior
|
|
|
2c2fa1 |
|
|
|
2c2fa1 |
gdb.base/gnu_vector.c printf the vector and gdb.base/gnu_vector.exp
|
|
|
2c2fa1 |
expects the output by gdb_test_multiple. Nowadays, the test doesn't
|
|
|
2c2fa1 |
expect the output from inferior_spawn_id, which is wrong. Even we
|
|
|
2c2fa1 |
change the test to expect from inferior_spawn_id for the inferior
|
|
|
2c2fa1 |
output, it is still possible the inferior exit before tcl/expect gets
|
|
|
2c2fa1 |
the inferior output. We see this fail on both s390x-linux and
|
|
|
2c2fa1 |
ppc-linux on buildbot,

In order to address these two shortcomings above in gnu_vector.exp,
|
|
|
2c2fa1 |
this patch rewrites the test a little bit. Get rid of checking the
|
|
|
2c2fa1 |
inferior output, and instead checking them by printing them. In this
|
|
|
2c2fa1 |
way, the test can also be run on the target without inferior io
|
|
|
2c2fa1 |
(gdb,noinferiorio is set in the board file).
