binutils-gdb/gas/config/xtensa-istack.h
Bob Wilson 7c430684d0 * config/xtensa-istack.h (TInsn): Replace dwarf2_line_info with an
unsigned line number.  Do not include "dwarf2dbg.h".
	* config/tc-xtensa.c (md_pseudo_table): Remove entry for "loc".
	(xtensa_dwarf2_directive_loc, xtensa_dwarf2_emit_insn): Delete.
	(xg_build_to_insn, xg_build_token_insn): Update TInsn uses.
	(md_assemble): Use as_where instead of dwarf2_where.
	(xg_assemble_vliw_tokens): Use unsigned line numbers instead of
	dwarf2_line_infos.  Change to call new_logical_line followed by
	dwarf2_emit_insn.
