Re: [PATCH] gdb passes and returns incorrect values when dealing with small array on Sparc


    From: Vladimir Mezentsev <vladimir.mezentsev@oracle.com>
    
    gdb has a special type (TYPE_CODE_ARRAY) to support the gcc extension
    (https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html).
    TYPE_CODE_ARRAY is handled incorrectly for both (32- and 64-bit) modes on Sparc machines.
    
    Tested on sparc64-linux-gnu and sparc-solaris (32- and 64-bit mode).
    No regressions.
    
    gdb/ChangeLog:
    2017-05-12  Vladimir Mezentsev  <vladimir.mezentsev@oracle.com>
    
    	* sparc-tdep.c (sparc_structure_return_p)
    	(sparc_arg_on_registers_p): New functions.
    	(sparc32_store_arguments): Use them.
    	* sparc64-tdep.c (sparc64_16_byte_align_p)
    	(sparc64_store_floating_fields, sparc64_extract_floating_fields):
    	Handle TYPE_CODE_ARRAY.


LGTM.  Ok for master?
