  • a12181748b Make ass and int built with clang --- surprisingly easy. David Given 2018-06-09 21:18:50 +09:00
  • 59b383afd0 Make the em interpreter build --- again, lots of warnings, so it probably won't work on clang. I have no idea whether it runs or not as building a e.out program is quite hard and needs a special platform. David Given 2018-06-09 21:13:31 +09:00
  • d10a594c04 Get ass running --- it's very K&R and almost certainly won't build on clang, but it works on gcc. David Given 2018-06-09 14:10:45 +09:00
  • ae3074cd9a
         Merge pull request #93 from davidgiven/dtrg-pc86-2 David Given 2018-06-08 21:40:25 +09:00
  • 19cd42124f Rearrange the tests into sets; allow plats to skip sets; pc86 and linux68k now skip the tests which use floating point instructions (as their emulators don't support them). David Given 2018-06-08 15:59:04 +09:00
  • b94199aba7

  • 396795105f Beat the 68k simulator into enough shape that at least *some* of the tests pass. David Given 2018-06-06 22:39:43 +09:00
  • 4b26f75d23 Hang on, the 68k is big-endian --- I'm extracting words (and bytes) from longs incorrectly. David Given 2018-06-06 12:49:21 +09:00
  • 2cf39be752 Get the emulator to the point where it'll start to run code; it then fails, because the version of Musashi I imported doesn't support floating point... David Given 2018-06-05 23:17:22 +09:00

  • c6b9446722 Check in the x86emu-based emulator. Sadly, just like the 8086tiny-based emulator, FPU instructions aren't supported. David Given 2018-06-04 16:19:45 +09:00
  • d908f9cfb2 Modify the pc86 test harness to use 8086tiny instead of qemu. Sadly, some tests fail. David Given 2018-06-03 15:13:43 +02:00
  • 0eb89d5d95 Add a clean copy of the Musashi emulator. David Given 2018-06-05 17:04:47 +09:00
  • 3f049a4c29 Basic mid now throws an error on out-of-bounds parameters rather than returning an uninitialised pointer (and crashing). David Given 2018-06-05 09:53:56 +09:00
  • 9dede01efe Fix bogus test. David Given 2018-06-05 09:41:31 +09:00

  • 911ce7ceb5 Crudely tweak some of the prototypes to please clang, which is pickier about K&R C than gcc is. David Given 2018-06-02 21:31:18 +02:00

  • be32d258cb Don't need ed any more in the travis configuration. David Given 2018-06-02 18:08:55 +02:00
  • 05ddefad65 Adopt a copy of Minix 2's ed; this allows the ACK's antiquated ed scripts to run with a minimum of tweaking. Rewriting them for modern ed looks really hard. David Given 2018-06-02 18:02:51 +02:00

  • ebba76e08f Don't read INSTR(l) after oldline(l) frees it. George Koehler 2018-03-11 20:10:13 -04:00
  • 4cb4bdc85f There are two places where names are added to the global symbol table; one via the -U command line option, and one via file scanning. Turns out only the second would increment the number of global names, so adding names with -U would cause names found via scanning to fall off the end of the list! This wouldn't cause linker errors because fixups don't use the list, but would cause the generated symbol table in the output to be incorrect. David Given 2018-03-11 12:37:23 +01:00
  • d5a9f1541a lchar() needs to return the character written. (This happens by magic on 386, but no on PPC.) See #72. David Given 2018-03-11 11:00:35 +01:00
