GCC won`t emit my instriction

["Alex Hill via gcc-help" <gcc-help@gcc.gnu.org>]

I need to reduce amount of branches in code. There is exist benchmark called median it have some code like:
    if ( A < B )
            return A = foo[i];
        else
            return B = foo[i];
I wrote a pattern in machine description file *.md to avoid branches:
    (define_insn "smin<GPR:mode>3"
      [
        (set 
          (match_operand:GPR 0 "register_operand" "=r")
            (if_then_else:GPR
          (lt:GPR 
            (match_operand:GPR 1 "register_operand" " r")
            (match_operand:GPR 2 "register_operand" " r"))
        (match_dup 1)
        (match_dup 2)))
      ]
      ""
      "min\t%0,%1,%2"
      [(set_attr "type" "move")
       (set_attr "mode" "<MODE>")]) 
It works in case of simple comparison:
    if ( A < B )
            return A ;
        else
            return B;
GCC emit:
    min a0,a0,a1    # 9 smindi3 [length = 4]
    ret # 21    simple_return   [length = 4]
But if i try same, but with indexed variable( array ): it won`t works:
    if ( A < B )
            return A = foo[i];
        else
            return B = foo[i];
GCC emit:
    blt a0,a1,.L5   # 11    *branch_orderdi [length = 4]
    sd  a1,8(a2)    # 18    *movdi_64bit/4  [length = 4]
    mv  a0,a1   # 8 *movdi_64bit/1  [length = 4]
    ret # 34    simple_return   [length = 4]
    .L5:
    sd  a0,8(a2)    # 13    *movdi_64bit/4  [length = 4]
    ret # 28    simple_return   [length = 4]
I need to GCC emit something like this:
    min a0,a0,a1    # 9 smindi3 [length = 4]
    sd  a0,8(a2)    # 18    *movdi_64bit/4  [length = 4]
    ret # 34    simple_return   [length = 4]
I appreciate any help, and i desperate to find a desicion, i tried to look into GIMPLE to change conditions of MIN_EXPR, but there is no(almost) any documentation, and sources are VERY puzzling((


Kind regards Alex Hill.
