In gdb.base/watchpoint-hw-hit-once.exp, test scans source and set
breakpoint on the line having "break-at-exit",
gdb_breakpoint [gdb_get_line_number "break-at-exit"]
However, in watchpoint-hw-hit-once.c, there are two lines having
this key word:
dummy = 1; /* Stub to catch break-at-exit after WATCHEE has been hit. */
dummy = 2; /* break-at-exit */
so the test sets breakpoint on the first one, while I think it is
expected to set breakpoint on the second one, as far as I can tell
from the comments in watchpoint-hw-hit-once.c:
/* Stub lines are present as no breakpoints/watchpoint gets hit if current PC
already stays on the line PC while entering "step"/"continue". */
This patch is to change the source matching pattern so that test
can correctly set breakpoint on the right line. This patch fixes
a fail we found on arm-none-eabi target.
(gdb) PASS: gdb.base/watchpoint-hw-hit-once.exp: continue
continue^M
Continuing.^M
^M
*** EXIT code 0^M
[Inferior 1 (Remote target) exited normally]^M
(gdb) FAIL: gdb.base/watchpoint-hw-hit-once.exp: continue to break-at-exit (the program exited)
Run it again on x86_64-linux, no result changes.
