4.5.6 Environment Variables</A>

<P>
The PIC14 port recognizes the following environment variables:
<DL>
<DT><STRONG>SDCC_PIC14_SPLIT_LOCALS<A NAME="3006"></A><A NAME="3007"></A></STRONG></DT>
<DD>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.
</DD>
