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: add 8085 instruction support
 2019-02-11 21:35:16 +01:00
David Given e8994afdf0 Apply Alan Cox's patch to add the 8085 extended instructions to the i80 
assembler.

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 c95d5db372 Replace mkstemp() with the more modern and safer and simpler tmpfile(). 2019-02-10 14:36:15 +01:00
David Given 63fa647bc9 freopen() appears to be problematic on OSX; as it's only ever used to rewind 
files, replace with rewind().

David Given c8c48221b3 Second try at removing common symbols. 2019-02-10 13:11:03 +01:00
David Given 8a7077d5a9 Change the way external symbols are defined to avoid COMMON symbols, which 
don't work on OSX very well.
