David Given 91c75f81b5 Call cmps rather than cmpu for bge... make cmps and cmpu rsts. Apply various 
other tiny optimisations.
 2019-02-15 00:38:39 +01:00
David Given 2924ce8ffa Use nicely optimised helper tools to do signed comparisons of words. Star Trek 
goes from 40452 to 39890 bytes.

i80: fix pathological behaviour in asp
 2019-02-14 00:13:41 +01:00
David Given 8eaa11ac72 Turns out that every time the compiler tried to do a stack retraction with asp, 
it would flush registers onto the stack. This stops it doing this. Star Trek
goes from 40779 to 40452 bytes.

i80: use helper functions for stack access
 2019-02-13 22:56:18 +01:00
David Given 6e3ba8e9a0 Merge from default. 2019-02-13 22:46:00 +01:00
David Given 79a38ecc08 Instead of using parameterised rsts for stack access, add a huge swathe of 
automatically built helper tools. Star Trek goes up from 40243 to 40779 bytes,
but should be a lot faster.

David Given f70659f460 Don't do weird things if files starting with a hyphen exist in the build 
directory.

David Given 8200f041c2 Fix issue with logical operations and small signed constants which turned out 
to affect multiple platforms.

i80: fix bad code in comparisons
 2019-02-12 22:29:01 +01:00
David Given f4b45f1ed7 Fix bad code generation due to not correctly flushing the stack before 
comparisons.

Bugfix of compilation on gcc 4.8
 2019-02-12 21:51:46 +01:00
carl 664338aa49 Fix compilation issue on C90 compilers (gcc 4.8 was failing to compile with default flags) - updated following comment. 2019-02-13 00:17:45 +08:00
David Given 360e1525ae Replace the non-working Z80 style signed comparison sign adjustment with 
something which actually works on the 8080. Sadly, Star Trek is up to
40243 bytes again.

i80: fix signed comparisons
 2019-02-11 21:09:52 +01:00
David Given f1b128baeb Signed comparisons now work correctly; sadly, Star Trek increases from 39656 to 
39726 bytes. Note that the emulator doesn't set P/V correctly and all the tests
fail. Testing in z80ex works fine.

i80: more code generator improvements
 2019-02-10 19:45:00 +01:00
David Given fca54ccc1b Improve subtractions, using dad and inline constants where possible. Shrinks 
Star Trek from 39740 to 39656 bytes.
 2019-02-10 19:40:48 +01:00
David Given 7d34cd7407 Simplify simple comparisons and use inlie constants where possible. Reduces 
Star Trek from 39771 to 39740 bytes.
 2019-02-10 19:22:43 +01:00
David Given 35d1f36ca4 Use pop rather than inx;inx to retract the stack; consumes a register but 
halves the number of calls. Reduces Star Trek from 39976 to 39771 bytes.
 2019-02-10 18:57:20 +01:00
David Given b34ff2bdec Teach the i80 code generator how to do left shifts by using dad hl; prevents it 
from calling out to .sli2 for simple shifts. Shrinks Star Trek from 40055 bytes
to 39976.

David Given 63fa647bc9 freopen() appears to be problematic on OSX; as it's only ever used to rewind 
files, replace with rewind().

don't work on OSX very well.
