* tree.h (enum tree_index): Add TI_VA_LIST_GPR_COUNTER_FIELD
and TI_VA_LIST_FPR_COUNTER_FIELD.
(va_list_gpr_counter_field, va_list_fpr_counter_field): Define.
* tree-pass.h (pass_stdarg): Add.
* tree-optimize.c (init_tree_optimization_passes): Add pass_stdarg.
* tree-stdarg.c: New file.
* tree-stdarg.h: New file.
* Makefile.in (OBJS-common): Add tree-stdarg.o.
(tree-stdarg.o): Add dependencies.
* function.h (struct function): Add va_list_gpr_size and
va_list_fpr_size fields.
* function.c (allocate_struct_function): Initialize them.
* target.h (struct gcc_target): Add stdarg_optimize_hook.
* target-def.h (TARGET_STDARG_OPTIMIZE_HOOK): Define.
(TARGET_INITIALIZER): Add it.
* config/i386/i386.c (ix86_build_builtin_va_list): Initialize
va_list_{g,f}pr_counter_field.
(ix86_setup_incoming_varargs): Don't do anything if reg_save
area will not be used. Only save registers that tree-stdarg.c
detected they need saving.
(ix86_va_start): Don't set up fields that won't be used.
* config/rs6000/rs6000.c (rs6000_build_builtin_va_list): Initialize
va_list_{g,f}pr_counter_field.
(setup_incoming_varargs): Don't do anything if reg_save
area will not be used. Only save registers that tree-stdarg.c
detected they need saving.
(rs6000_va_start): Don't set up fields that won't be used.
* config/alpha/alpha.c: Include tree-flow.h and tree-stdarg.h.
(alpha_build_builtin_va_list): Initialize va_list_gpr_counter_field.
(va_list_skip_additions, alpha_stdarg_optimize_hook): New functions.
(TARGET_STDARG_OPTIMIZE_HOOK): Define.
* gcc.dg/tree-ssa/stdarg-1.c: New test.
* gcc.dg/tree-ssa/stdarg-2.c: New test.
* gcc.dg/tree-ssa/stdarg-3.c: New test.
