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.
