(BUILT_IN_FP, BUILT_IN_SP, BUILT_IN_SET_RETURN_ADDR_REG): Kill. (BUILT_IN_EH_STUB_OLD, BUILT_IN_EH_STUB, BUILT_IN_SET_EH_REGS): Kill. (BUILT_IN_EH_RETURN, BUILT_IN_DWARF_CFA): New. * c-decl.c (init_decl_processing): Update accordingly. * expr.c (expand_builtin): Likewise. * cp/decl.c (init_decl_processing): Likewise. * rtl.h (global_rtl): Add cfa entry. (virtual_cfa_rtx, VIRTUAL_CFA_REGNUM): New. (LAST_VIRTUAL_REGISTER): Update. * emit-rtl.c (global_rtl): Add cfa entry. (init_emit): Initialize it. * function.c (cfa_offset): New. (instantiate_virtual_regs): Initialize it. (instantiate_virtual_regs_1): Instantiate virtual_cfa_rtx. (expand_function_end): Call expand_eh_return. * tm.texi (ARG_POINTER_CFA_OFFSET): New. * except.c (current_function_eh_stub_label): Kill. (current_function_eh_old_stub_label): Likwise; update all references. (expand_builtin_set_return_addr_reg): Kill. (expand_builtin_eh_stub_old, expand_builtin_eh_stub): Kill. (expand_builtin_set_eh_regs): Kill. (eh_regs): Produce a third reg for the actual handler address. (eh_return_context, eh_return_stack_adjust): New. (eh_return_handler, eh_return_stub_label): New. (init_eh_for_function): Initialize them. (expand_builtin_eh_return, expand_eh_return): New. * except.h: Update prototypes. * flow.c (find_basic_blocks_1): Update references to the stub label. * function.h (struct function): Kill stub label elements. * libgcc2.c (in_reg_window): For REG_SAVED_REG, check that the register number is one that would be in the previous window. Provide a dummy definition for non-windowed targets. (get_reg_addr): New function. (get_reg, put_reg, copy_reg): Use it. (__throw): Rely on in_reg_window, not INCOMING_REGNO. Kill stub generating code and use __builtin_eh_return. Use __builtin_dwarf_cfa. * alpha.c (alpha_eh_epilogue_sp_ofs): New. (alpha_init_expanders): Initialize it. (alpha_expand_epilogue): Use it. * alpha.h: Declare it. * alpha.md (eh_epilogue): New. * m68h.h (ARG_POINTER_CFA_OFFSET): New. * sparc.h (ARG_POINTER_CFA_OFFSET): New. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@22436 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree.h | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) (limited to 'gcc/tree.h') diff --git a/gcc/tree.h b/gcc/tree.h index aee712fc97f..58293e49d5e 100644 --- a/gcc/tree.h +++ b/gcc/tree.h @@ -101,7 +101,6 @@ enum built_in_function BUILT_IN_FRAME_ADDRESS, BUILT_IN_RETURN_ADDRESS, BUILT_IN_AGGREGATE_INCOMING_ADDRESS, - BUILT_IN_CALLER_RETURN_ADDRESS, BUILT_IN_APPLY_ARGS, BUILT_IN_APPLY, BUILT_IN_RETURN, @@ -110,16 +109,13 @@ enum built_in_function BUILT_IN_TRAP, /* Various hooks for the DWARF 2 __throw routine. */ - BUILT_IN_FP, BUILT_IN_SP, BUILT_IN_UNWIND_INIT, + BUILT_IN_DWARF_CFA, BUILT_IN_DWARF_FP_REGNUM, BUILT_IN_DWARF_REG_SIZE, BUILT_IN_FROB_RETURN_ADDR, BUILT_IN_EXTRACT_RETURN_ADDR, - BUILT_IN_SET_RETURN_ADDR_REG, - BUILT_IN_EH_STUB_OLD, - BUILT_IN_EH_STUB, - BUILT_IN_SET_EH_REGS, + BUILT_IN_EH_RETURN, /* C++ extensions */ BUILT_IN_NEW, -- cgit v1.2.1
