PR rtl-opt/33721
* explow.c (allocate_dynamic_stack_space): Add REQUIRED_ALIGN parm,
remove TARGET parm, convert KNOWN_ALIGN parm to SIZE_ALIGN. Honor
required_align, tidy the code a bit. Emit split_stack code in the
right place. Mark the return value with the alignment properly.
* expr.h (allocate_dynamic_stack_space): Update decl.
* builtins.c (expand_builtin_apply): Update call to
allocate_dynamic_stack_space.
(expand_builtin_alloca): Likewise. Remove TARGET parameter.
* calls.c (initialize_argument_information): Update call to
allocate_dynamic_stack_space.
(expand_call): Likewise.
* cfgexpand.c (get_decl_align_unit): Don't limit alignment.
Don't update_stack_alignment here.
(alloc_stack_frame_space): Make ALIGN unsigned.
(stack_var_cmp): Sort by alignment too.
(partition_stack_vars): Don't merge large and small alignment vars.
(expand_one_stack_var_at): Add BASE and BASE_ALIGN parameters.
Take care when BASE is not virtual_stack_vars_rtx.
(expand_stack_vars): Allocate dynamic stack space for large
alignment variables.
(expand_one_stack_var): Update all to expand_one_stack_var_at.
(defer_stack_allocation): True for large alignment vars.
(update_stack_alignment): Merge into ...
(expand_one_var): ... here.
(gimple_expand_cfg): Place code from expand_stack_vars.
