    Test case for DW_OP_GNU_implicit_pointer support
    
    * testsuite/systemtap.base/implicitptr.c: New file.

commit 1220de76265ef75bbd208e89ddc24713202b3955
Author: Roland McGrath <roland@redhat.com>
Date:   Tue Jul 27 04:55:48 2010 -0700

    loc2c internal reorganization and DW_OP_GNU_implicit_pointer handling
    
    * loc2c.c (struct location_context): New type.
    (struct location): New member context points to that.
    Add pointer variant with .type = loc_implicit_pointer.
    (alloc_location): Take just context pointer as argument.
    (FAIL): Use context pointer.
    (new_context): New function.
    (translate_constant): New function, broken out of ...
    (c_translate_constant): ... here.  Call it.
    (new_synthetic_loc): Don't take pool argument, origin->context has it.
    (lose): Take new argument LEN, overall length of LEXPR.
    Don't mention the offset into LEXPR if LEXPR is NULL or I is past LEN.
    (translate): Take context argument instead of pool, addrbias.
    Handle DW_OP_GNU_implicit_pointer.
    (location_from_address): Take context argument instead of pool, fail,
    fail_arg, emit_address, dwbias, attr, address, fb_attr, cfa_ops.
    (location_from_attr): New function.
    (translate_offset): New function, broken out of ...
    (location_relative): ... here.  Call it.
    Take context argument instead of pool, dwbias, attr, address.
    (c_translate_location): Use new_context.
    (c_translate_argument): Likewise.
    (emit_base_fetch): Diagnose for loc_implicit_pointer.
    (emit_base_store): Likewise.
    (c_translate_addressof, c_translate_array): Likewise.
    (discontiguify): Likewise.  Take context argument instead of pool.
    (c_translate_pointer): Handle loc_implicit_pointer.
    (c_translate_array_pointer): Likewise.
    (c_emit_location): Likewise.
