[sdcc-devel] Commit: q bunch of ds390 code generator improvements

[Kevin V. <ke...@vi...>]

I just enabled a whole bunch of optimizations in the ds390 code
generator (I've been sneakily checking them in #ifdef'd out for the
past several days). Now that it passes all my tests, it's time to
turn 'em on (Johan, thanks for the calculator test case; you wouldn't
believe how many bugs that caught. Or maybe you would!)

Anyway, this is yet another big hairy checkin (the last one for some
time, I hope). So if your code goes to hell, try removing the #define
LAZY_DPS_OPT in ds390/gen.c. If that fixes your problem, please let
me know.

By the way, this gets us up to 416 dhry/sec on a TINI. ANd I'm much
less ashamed of the generated code.
 
        Peace,
                Kevin
