2000-02-09  Mark Kettenis  <kettenis@gnu.org>

	* configure.in: Check for lwpid_t, psaddr_t, prgregset_t and

	Changes for AIX 4.3:
	* rs6000-tdep.c (rs6000_fix_call_dummy): Set TOC register
	to correct value for generic dummy frames.  When using
	generic dummy frames, don't attempt to write TOC value or
	function to call into the call dummy.
        (rs6000_push_arguments): Adapt USE_GENERIC_DUMMY_FRAMES
	code to also handle the PowerOpen ABI.
	(ppc_push_return_address): Enable for all ports.
	* config/powerpc/tm-ppc-aix.h (USE_GENERIC_DUMMY_FRAMES,
	PUSH_DUMMY_FRAME, PUSH_RETURN_ADDRESS, GET_SAVED_REGISTER, 
	CALL_DUMMY_BREAKPOINT_OFFSET, CALL_DUMMY_LOCATION,
	CALL_DUMMY_ADDRESS, CALL_DUMMY_START_OFFSET): Override defaults
	provided by generic RS6000 definitions so that call dummies
	are implemented using generic dummy frames instead.

	* rs6000-nat.c (store_inferior_registers): Call exec_one_dummy_insn()
	prior to changing the stack pointer via ptrace().  Also, ignore
	attempts to store to undefined registers that are less than
	NUM_REGS.

	* rs6000-tdep.c (DUMMY_FRAME_SIZE): Change size of the dummy
	frame from 436 to 448 to account for alignment padding.
	(rs6000_push_arguments): Obtain actual register size instead
	of assuming the register is 4 bytes long.  [There's still
	more work to be done to totally remove the 4 byte assumption,
	however.]  Make sure the stack is 16 byte aligned as required
	by the PowerOpen ABI.  Also, make sure that small structures
	passed in registers are properly aligned within the register.

2000-02-15  Jesper Skov  <jskov@cygnus.co.uk>

	Patch applied by Kevin Buettner <kevinb@redhat.com>
	
	* rs6000-tdep.c (skip_prologue): skip copying of argument
	registers to local variable registers.
