--- Comment #7 from Richard Henderson <rth at gcc dot gnu.org> 2010-10-09 22:05:55 UTC --- Author: rth Date: Sat Oct 9 22:05:51 2010 New Revision: 165240 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=165240 Log: 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.
