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.
