The PIC14 port recognizes the following environment variables:
- SDCC_PIC14_SPLIT_LOCALS
- If set and not empty, sdcc will allocate
each temporary register (the ones called r0xNNNN) in a section of
its own. By default (if this variable is unset), sdcc tries to cluster
registers in sections in order to reduce the BANKSEL overhead when
accessing them.
