So far the gnu_vector test was limited to "static" aspects of GDB's
vector support, like evaluating vector-valued expressions. This patch
enriches the test and adds checks for GDB's vector ABI support as well.
The new checks particularly verify inferior function calls with vector
arguments and GDB's handling of vector return values.
The test now attempts to compile for the target's "native" architecture,
such that a hardware vector ABI is used if available.
Since GDB has no vector ABI support for x86 and x86_64 targets, most of
the new checks are KFAILed there.
gdb/testsuite/ChangeLog:
* gdb.base/gnu_vector.c: Include stdarg.h and stdio.h.
(VECTOR): New macro. Use it...
(int4, uint4, char4, float4, int2, longlong2, float2, double2):
...for these typedefs.
(int8, char1, int1, double1): New typedefs.
(struct just_int2, struct two_int2): New structures.
(add_some_intvecs, add_many_charvecs, add_various_floatvecs)
(add_structvecs, add_singlevecs): New functions.
(main): Call add_some_intvecs twice.
* gdb.base/gnu_vector.exp: Drop GCC version check; just attempt
the compile and exit upon failure. Try compiling for the "native"
architecture. Test inferior function calls with vector arguments
and vector return value handling with "finish" and "return".
gdb/ChangeLog
* valarith.c (value_vector_widen): New function for replicating a
scalar into a vector.
(value_binop): Use value_vector_widen to widen scalar to vector
rather than casting, this better matches gcc C behaviour.
* valops.c (value_casst): Update logic for casting between vector
types, and for casting from scalar to vector, try to match gcc C
behaviour.
* value.h (value_vector_widen): Declare.
* opencl-lang.c (opencl_value_cast): New opencl specific casting
function, handle special case for casting scalar to vector.
(opencl_relop): Use opencl_value_cast.
(evaluate_subexp_opencl): Use opencl_value_cast instead of
value_cast, and handle BINOP_ASSIGN, UNOP_CAST, and UNOP_CAST_TYPE
in order to use opencl_value_cast.
gdb/testsuite/ChangeLog
* gdb.base/gnu_vector.c: New variable for use in tests.
* gdb.base/gnu_vector.exp: Update and extend tests to reflect
changes in scalar to vector casting and widening.
* gdb.python/py-type.c: New variables for use in tests.
* gdb.python/py-type.exp: Update vector related tests to reflect
changes in scalar to vector casting and widening.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.

* c-typeprint.c (c_print_type): Don't print a space for vector
types, this is handled within the suffix.

structs / unions containing vectors.
