- Only every single dsp, and an increasing number of otherwise conventional
and/or vector extended architectures targeted to improve the support for
the same? (not to mention corresponding modular and/or specific algorithm
addressing mode support, which may ideally be the target of optimized code
mapping to improve performance, which correspondingly would ideally
require their generic definition)
(But acknowledge these machines tend not to be targeted as the CPU of a PC,
if that is the intended focus of GCC)
