Yes, helper.c is compiled with the global register variables and the code is 
called directly from the op_xxx functions, but one needs the global register 
variables to access global data, these contain the required environment for 
the emulation. AFAIK helper2.c is used by the CODE_COPY branch on i386 with 
even stronger restrictions, but I may be wrong here.
