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. + 2002-07-02 Kaveh R. Ghazi <ghazi@caip.rutgers.edu> * c-parse.in (parsing_iso_function_signature): New variable. |
