New Revision: 172369

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=172369
Log:
	* dwarf2out.c (struct dw_cfi_struct): Remove member dw_cfi_next.
	(dw_cfi_ref): Add DEF_VEC_P and some DEF_VEC_ALLOC_Ps.
	(cfi_vec): New typedef.
	(struct dw_fde_struct): Make dw_fde_cfi a cfi_vec. Replace
	dw_fde_switch_cfi with an integer dw_fde_switch_cfi_index.
	(cie_cfi_vec): New static variable.
	(cie_cfi_head): Delete.
	(add_cfi): Accept a cfi_vec * as first argument. All callers and
	declaration changed. Use vector rather than list operations.
	(new_cfi): Don't initialize the dw_cfi_next field.
	(add_fde_cfi): Allocate cie_cfi_vec if necessary. Use vector
	rather than list operations.
	(lookup_cfa): Use vector rather than list operations.
	(output_cfis): New argument upto. Accept a cfi_vec rather than
	a dw_cfi_ref list head as argument. All callers changed.
	Iterate over the vector using upto as a maximum index.
	(output_all_cfis): New static function.
	(output_fde): Use vector rather than list operations. Use the
	new upto argument for output_cfis rather than manipulating a
	list.
	(dwarf2out_begin_prologue): Change initializations to match
	new struct members.
	(dwarf2out_switch_text_section): Initialize dw_fde_switch_cfi_index
	from the vector length rather than searching for the end of a list.
	Use output_all_cfis.
	(convert_cfa_to_fb_loc_list): Use vector rather than list operations.
