	gcc/testsuite  : ChangeLog 
	gcc/testsuite/gcc.c-torture/execute: simd-1.c simd-2.c 

Log message:
	gcc:
	* optabs.c (expand_vector_binop): Don't store using a SUBREG smaller
	than UNITS_PER_WORD, unless this is little endian and the first unit
	in this word.  Let extract_bit_field decide how to load an element.
	Force arguments to matching mode.
	(expand_vector_unop): Likewise.
	
	* simplify-rtx.c (simplify_subreg): Don't assume that all vectors
	consist of word_mode elements.
	* c-typeck.c (build_binary_op): Allow vector types for BIT_AND_EXPR,
	BIT_ANDTC_EXPR, BIT_IOR_EXPR and BIT_XOR_EXPR.
	(build_unary_op): Allow vector types for BIT_NOT_EPR.
	* emit-rtl.c (gen_lowpart_common): Use simplify_gen_subreg for
	CONST_VECTOR.
	* optabs.c (expand_vector_binop): Try to perform operation in
	smaller vector modes with same inner size.  Add handling of AND, IOR
	and XOR.  Reject expansion to inner-mode sized scalars when using
	OPTAB_DIRECT.  Use simplify_gen_subreg on constants.
	(expand_vector_unop): Try to perform operation in smaller vector
	modes with same inner size.  Add handling of one's complement.
	When there is no vector negate operation, try a vector subtract
	operation.  Use simplify_gen_subreg on constants.
	* simplify-rtx.c (simplify_subreg): Add capability to convert vector
	constants into smaller vectors with same inner mode, and to
	integer CONST_DOUBLEs.
	
	gcc/testsuite:
	* gcc.c-torture/execute/simd-1.c (main): Also test &, |, ^, ~.
	* gcc.c-torture/execute/simd-2.c (main): Likewise.
