I think there are 2 problems in emit_store_flag,
1 minor and 1 major.

the minor: subtarget is declared twice; so debugging is difficult.

the major: the call to compare_from_rtx at line 2802 could invert
the comparison; so icode should be reset using the comparison code
of comparison.  I wrote my MD file using the example in the docu-
mentation. So the compare_from_rtx, in fact, actually stores both 
operands with an order which doesn't corespond to the old code.
I know I can fix the problem if I store the new code and compare
it with the old one during the generation of the comparison
pattern; but it is better to fix the problem in the emit_store_flag
function.
