optabs.c (expand_vector_binop): Don't store using a SUBREG smaller than UNITS_PER_WORD...
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.
