	(LAST_VIRTUAL_REGISTER): Increase by one.
	(REGNO_PTR_FRAME_P): Use LAST_VIRTUAL_POINTER_REGISTER
	instead of LAST_VIRTUAL_REGISTER.
	* function.c (instantiate_new_reg): Handle
	virtual_preferred_stack_boundary_rtx.
	* emit-rtl.c (init_virtual_regs): Handle
	VIRTUAL_PREFERRED_STACK_BOUNDARY_REGNUM.
	(init_emit_regs): Initialize virtual_preferred_stack_boundary_rtx.
	* explow.c (round_push): If crtl->preferred_stack_boundary
	is smaller than MAX_SUPPORTED_STACK_ALIGNMENT, use
	virtual_preferred_stack_boundary_rtx alignment instead of
	crtl->preferred_stack_boundary alignment.
	(allocate_dynamic_stack_space): Use CONST_INT_P and REG_P
	macros.  Never decrease crtl->preferred_stack_boundary,
	use crtl->preferred_stack_boundary or MAX_SUPPORTED_STACK_ALIGNMENT
	instead of PREFERRED_STACK_BOUNDARY.  Don't modify
	stack_pointer_delta in dynamic allocation, even when size
	is constant.
	(probe_stack_range, anti_adjust_stack_and_probe): Use CONST_INT_P
	macro.
	* print-rtl.c (print_rtx): Handle
	VIRTUAL_PREFERRED_STACK_BOUNDARY_REGNUM.
	* config/alpha/alpha.h (NONSTRICT_REG_OK_FP_BASE_P): Use
	LAST_VIRTUAL_POINTER_REGISTER instead of LAST_VIRTUAL_REGISTER.
	* config/frv/frv.c (frv_emit_movsi): Likewise.
	* config/arm/arm.c (thumb1_legitimate_address_p): Likewise.
	* config/rs6000/rs6000.c (virtual_stack_registers_memory_p):
	Likewise.

	* gcc.dg/torture/stackalign/alloca-6.c: New test.
	* gcc.target/i386/pr45234.c: New test.

	Revert:
	2010-09-17  H.J. Lu  <hongjiu.lu@intel.com>

	PR middle-end/45234
	* calls.c (expand_call): Make sure that all variable sized
	adjustments are multiple of preferred stack boundary after
	stack alignment.
