binutils* dwarf.c (struct State_Machine_Registers): Add view field. (reset_state_machine): Reset view. (process_extended_line_op): Reset view when appropriate. (display_debug_lines_raw): Increment or reset view when appropriate. Print nonzero views. Support print view resets, disabled by default. (display_debug_lines_decoded): Likewise. Disambiguate op_code tests, enabling printing of end_sequence. * testsuite/binutils-all/dw2-1.W: Add nonzero views. * testsuite/binutils-all/dw2-3.W: Likewise. * testsuite/binutils-all/dw2-3gabi.W: Likewise. * testsuite/binutils-all/dw5.W: Add end sequence lines. * testsuite/binutils-all/i386/compressed-1a.d: Add nonzero views. * testsuite/binutils-all/libdw2-compressedgabi.out: Likewise. * testsuite/binutils-all/objdump.W: Likewise. * testsuite/binutils-all/objdump.WL: Add end sequence lines. * testsuite/binutils-all/x86-64/compressed-1a.d: Add nonzero views. gas * doc/as.texinfo (.loc): Document view support. * dwarf2dbg.c (unused): Check offset of next in struct line_entry.
