[sdcc-devel] New register allocator for hc08

[Philipp K. K. <pk...@sp...>]

Dear users of the hc08 port,

Erik and me have been working on some improvements in the hc08 code
generation and register allocator. The work can be found in the
optralloc-hc08 branch:

svn co
https://sdcc.svn.sourceforge.net/svnroot/sdcc/branches/optralloc-hc08/sdcc
sdcc-ohc08

All regression tests pass for me, and in the regression tests I
currently see a code size reduction of about 6% compared to sdcc from
trunk. You might want to try this branch and see if it improves code
size for you, if compilation speed is ok, and if there are any bugs.

After some more testing and polishing this work will probably make it to
trunk, and then appear in the 3.2.0 or 3.3.0 release.

Philipp
