No, they are not.  Perhaps the patch that added them

        * tree-inline.c (inlinable_function_p): Improve heuristics
        by using a smoother function to cut down allowable inlinable 
size.
        * param.def: Add parameters max-inline-insns-single,
        max-inline-slope, min-inline-insns that determine the exact
        shape of the above function.
        * param.h: Likewise.

should be reverted until this is fixed.  (-fmax-inline-insns was broken 
at
the same time so that it no longer works to increase the size limit.)
