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.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
