When running test-case gdb.testsuite/gdb-caching-proc-consistency.exp with
target board native-gdbserver, we run into:
...
(gdb) ERROR: tcl error sourcing gdb.testsuite/gdb-caching-proc-consistency.exp.
ERROR: gdbserver does not support attach 4827 without extended-remote
while executing
"error "gdbserver does not support $command without extended-remote""
(procedure "gdb_test_multiple" line 51)
invoked from within
"gdb_test_multiple "attach $test_pid" "can spawn for attach" {
-re -wrap "$attaching_re\r\n.*ptrace: Operation not permitted\\." {
# Not permitte..."
(procedure "gdb_real__can_spawn_for_attach_1" line 27)
invoked from within
"gdb_real__can_spawn_for_attach_1"
...
The problem is that:
- can_spawn_for_attach_1 is a helper function for can_spawn_for_attach,
designed to be called only from that function, and
- can_spawn_for_attach_1 is a gdb_caching_proc, and consequently
test-case gdb.testsuite/gdb-caching-proc-consistency.exp calls
can_spawn_for_attach_1 directly.
Fix this by copying the early-outs from can_spawn_for_attach to
can_spawn_for_attach_1.
Tested on x86_64-linux.
