Hi all,

  A question about vtable contents.  Once a vtable
entry is resolved using DoPrestub, sometimes those
vtable entries point to jump instructions, sometimes
call instructions, sometimes actual ecall code, and
some special cases for things like string allocation.

  My question is, sometimes ecall code is pointed to
directly by a vtable entry and sometimes the entry
points to a call instruction that calls the ecall
code.  What determines whether a vtable entry points
to ecall code directly or a jump instruction or a call
instruction.

thanks,

John
