e71e506883 This assert is redundant; not worth an extra #include. 2021-01-18 17:56:40 -05:00

9b92753e0a In theory this should 'execute' up to the first unconditional branch.
Where execution means: do very little.

17c3a3eb4b Seeks to switch to maintaining a bank of performers.
My thinking here is that for really simple processors there'll be 256 or less, meaning that they can be stored by simple uint8_t; for every other processor I can currently think of it'll likely be uint16_t.

Either way, that's a much better outcome than using plain pointers, which on architectures I currently build for will always be 8 bytes. For the simple processors I can get eight times as much into the cache; for the others four times.

I'd failed to configure my new computer appropriately, it seems.
