Subject: 	* gdb.base/watchpoint.c (func2): Initialize local_a.  Add
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bdddb4dec8340fcf738d014fe772c059eaf06053;p=binutils-gdb.git

	* gdb.base/watchpoint.c (func2): Initialize local_a.  Add
	marker comment at the beginning (after intialization).
	* gdb.base/watchpoint.exp (test_complex_watchpoint): Set func2
	breakpoint on marker comment instead of function begin.
	(test_wide_location_1): Do not expect HW watchpoints on 32-bit
	PowerPC.
	(test_wide_location_2): Do not expect HW watchpoints on 32-bit
	or 64-bit PowerPC.
	(do_tests): Consistently set can-use-hw-watchpoints to 0 if
	gdb,no_hardware_watchpoints flag is set.
	(initialize): Remove now redundant can-use-hw-watchpoints change.
