1) What if I have two different ARCH, like ARM7tdmi + ARM-Cortex?
Or worse - ARM + DSP on the same target?
2) What if GDB already knows about my threads?
3) GDB assumes a single address space for all threads - *MAYBE* true for
*SOME* multi-core cpu. But - not all multi-cores have common address
space. ie: Blackfin BF561 - has 2 cores, shares external SDRAM but -
each core has its own private on chip SRAM that is not accessible by the
other core, also the two cores are non-cache coherent.
