From a6c787e5b7ad773092038330079c7c62122ae7f7 Mon Sep 17 00:00:00 2001 From: jakub Date: Sat, 9 Apr 2005 17:19:58 +0000 Subject: * 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. * gcc.dg/tree-ssa/stdarg-4.c: New test. * gcc.dg/tree-ssa/stdarg-5.c: New test. * gcc.c-torture/execute/stdarg-4.c: New test. * gcc.dg/vmx/varargs-1.c (f1, f2, f3): Add missing va_end. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@97916 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/function.h | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'gcc/function.h') diff --git a/gcc/function.h b/gcc/function.h index a8ca403decd..b772752552f 100644 --- a/gcc/function.h +++ b/gcc/function.h @@ -423,8 +423,22 @@ struct function GTY(()) /* Nonzero if code to initialize arg_pointer_save_area has been emitted. */ unsigned int arg_pointer_save_area_init : 1; + + /* Number of units of general registers that need saving in stdarg + function.
