gcc : ChangeLog builtins.c calls.c expr.h function.c
Log message:
PR target/18916
* builtins.c (std_gimplify_va_arg_expr): Adjust alignment of *ap.
* expr.h (struct locate_and_pad_arg_data): Add "boundary".
* function.c (locate_and_pad_parm): Set new field.
(assign_parm_find_stack_rtl): Use it instead of FUNCTION_ARG_BOUNDARY.
Tweak where_pad test to include "none". Always set mem align for
stack_parm.
(assign_parm_adjust_stack_rtl): Discard stack_parm if alignment
not sufficient for type.
(assign_parm_setup_block): If stack_parm is zero on entry, always
make a new stack local. Block move old stack parm if necessary
to new aligned stack local.
(assign_parm_setup_stack): Use a block move to handle
potentially misaligned entry_parm.
(assign_parms_unsplit_complex): Specify required alignment when
creating stack local.
* calls.c (compute_argument_addresses): Override alignment of stack
arg calculated from its type with the alignment given by
FUNCTION_ARG_BOUNDARY.
(store_one_arg): Likewise.
