* rtl.h (enum global_rtl_index): Add
GR_VIRTUAL_PREFERRED_STACK_BOUNDARY.
(LAST_VIRTUAL_POINTER_REGISTER): Define.
(virtual_preferred_stack_boundary_rtx,
VIRTUAL_PREFERRED_STACK_BOUNDARY_REGNUM): Define.
(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.

* calls.c (expand_call): Make sure that all variable sized
adjustments are multiple of preferred stack boundary after
stack alignment.
