  • 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 2019-02-13 22:45:22 +01:00
  • f70659f460 Don't do weird things if files starting with a hyphen exist in the build directory. David Given 2019-02-13 22:42:05 +01:00

  • 664338aa49 Fix compilation issue on C90 compilers (gcc 4.8 was failing to compile with default flags) - updated following comment. carl 2019-02-13 00:17:45 +08:00
  • 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. David Given 2019-02-12 11:57:37 +01:00

  • 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. David Given 2019-02-11 20:46:06 +01:00

  • 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. David Given 2019-02-10 18:57:20 +01:00
  • 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 2019-02-10 18:44:47 +01:00

  • ac856f3b09 The approach I was taking to csa and csb turns out not to work --- critical edge splitting can cause new basic blocks to be added to the graph, but while the graph itself gets properly rewritten the descriptor tables can't be updated to take these into account, so they end up pointing at the wrong blocks.
