Using "taskset -c 0" I run into this timeout:
...
(gdb) PASS: gdb.threads/step-N-all-progress.exp: non-stop=on: \
target-non-stop=on: continue to breakpoint: break here
next 3^M
[New Thread 0x7ffff7dbd6c0 (LWP 10202)]^M
50 return 0;^M
(gdb) [Thread 0x7ffff7dbd6c0 (LWP 10202) exited]^M
FAIL: gdb.threads/step-N-all-progress.exp: non-stop=on: target-non-stop=on: \
next 3 (timeout)
...
The problem is that this test:
...
gdb_test "next 3" "return 0;"
...
expects no output after the prompt.
Fix this by using -no-prompt-anchor.
Tested on x86_64-linux.

# Test that with "next N", all threads are resumed at each of the N

# steps. GDB used to have a bug where in target-non-stop targets, and

|
# in all-stop mode, after the first "next" (or "step/stepi/nexti"),
|
|
# GDB would prematurely stop all threads. For the subsequent N-1

# steps, only the stepped thread would continue running, while all the
|
|
# other threads would remain stopped.
