gdb/testsuite: make sure to consume the prompt in gdb.base/unwind-on-each-insn.exp
This test fails quite reliably for me when ran as:
$ taskset -c 1 make check TESTS="gdb.base/unwind-on-each-insn.exp" RUNTESTFLAGS="--target_board=native-gdbserver"
or more simply:
$ make check-read1 TESTS="gdb.base/unwind-on-each-insn.exp"
The problem is that the gdb_test_multiple call that grabs the frame id
from "maint print frame-id" does not consume the prompt. Well, it does
sometimes due to the trailing .*, but not always. If the prompt is not
consumed, the tests that follow get confused:
FAIL: gdb.base/unwind-on-each-insn.exp: gdb_breakpoint: set breakpoint at *foo
FAIL: gdb.base/unwind-on-each-insn.exp: disassemble foo
FAIL: gdb.base/unwind-on-each-insn.exp: get $sp and frame base in foo: get hexadecimal valueof "$sp"
... many more ...
Use -wrap to make gdb_test_multiple consume the prompt.
While at it, remove the bit that consumes the command name and do
exp_continue, it's not really necessary. And for consistency, do the
same changes to the gdb_test_multiple that consumes the stack address,
although that one was fine, it did consume the prompt explicitly.
