i386: Generate standard floating point scalar operation patterns
Standard floating point scalar operation patterns for combiner, which
preserve the rest of the vector, look like
(vec_merge:V2DF
(vec_duplicate:V2DF (reg:DF 87))
(reg/v:V2DF 85 [ x ])
(const_int 1 [0x1])]))
and
(vec_merge:V2DF
(vec_duplicate:V2DF
(op:DF (vec_select:DF (reg/v:V2DF 85 [ x ])
(parallel [ (const_int 0 [0])]))
(reg:DF 87))
(reg/v:V2DF 85 [ x ])
(const_int 1 [0x1])]))
This patch adds and generates such standard floating point scalar
operation patterns for +, -, *, /, > and <.
Tested on x86-64.
