as far as i know,  in master branch gc shape is used by default, and stenciling is used if unified is enable?  i guess we use gc shape in 1.18 and change to stenciling in 1.19 by using unified, or maybe we will implement gc shape in  unified before 1.19 release?

Yes, 1.18 uses gcshape. For 1.19, if we switch to the unified IR, the
current plan is that we will implement some form of gcshape in that
code.
