expr.c (do_store_flag): Expand vector comparison by building an appropriate VEC_COND_EXPR.
2011-09-29 Artjoms Sinkarovs <artyom.shinkaroff@gmail.com>
* expr.c (do_store_flag): Expand vector comparison by
building an appropriate VEC_COND_EXPR.
* c-typeck.c (build_binary_op): Typecheck vector comparisons.
(c_objc_common_truthvalue_conversion): Adjust.
* tree-vect-generic.c (do_compare): Helper function.
(expand_vector_comparison): Check if hardware supports
vector comparison of the given type or expand vector
piecewise.
(expand_vector_operation): Treat comparison as binary
operation of vector type.
(expand_vector_operations_1): Adjust.
* gcc.c-torture/execute/vector-compare-1.c: New testcase.
* gcc.c-torture/execute/vector-compare-2.c: Likewise.
* gcc.dg/vector-compare-1.c: Likewise.
* gcc.dg/vector-compare-2.c: Likewise.
