The recent patch to tree-nested.c:
2015-11-26 Pierre-Marie de Rodat <dero...@adacore.com>
PR debug/53927
* tree-nested.c (finalize_nesting_tree_1): Append a field to
hold the frame base address.
* dwarf2out.c (gen_subprogram_die): Generate for
DW_AT_static_link a location description that computes the value
of this field.
broke PTX, as it tried to use argp for the CFA. Fixed thusly. Also tidied up a
few bits of nvptx.h while I was there.

* config/nvptx/nvptx.h (FIRST_PARM_OFFSET): Add void cast.
(FRAME_POINTER_CFA_OFFSET): Define.
(struct nvptx_args): Use 'tree' type.
(INIT_CUMULATIVE_ARGS): Remove unnecessary do...while.
