Description scott CLA 2010-05-27 18:37:47 EDT 
Presently (in v3.3.0B2 code gen) there are many reset boot options provided in boot.c:

_c_int00()
_c_int00_noargs()
_c_int00_noinit()
_c_int00_noexit()
_c_int00_noinit_noexit()
_c_int00_mpu_init()
_c_int00_noargs_mpu_init()
_c_int00_noinit_mpu_init()
_c_int00_noexit_mpu_init()
_c_int00_noinit_noexit_mpu_init()

These different options allow saving small amounts of memory space for very small programs.  Depending upon build switches, the linker will select the optimum variant.  

We currently modify boot.c to add Startup reset function hooks to some of these variants.  Rather than add this hook to all appropriate variants of _c_int00*, we should consider removing all but the _c_int00() and _c_int00_mpu_init() variants.  The linker will default to one of these two variants if the others are not present.
