David Given 5111556d14 Got the emulator to the point where we're hitting the first major emulation bug 
(the calloc test hangs).
 2018-06-14 05:53:39 -07:00
David Given 853af4c4dd Some code runs (up to needing setcr0). 2018-06-14 04:41:21 -07:00
David Given b71145f79d Implement a non-functional skeleton of the PowerPC emulator (with, hopefully, 
most of the instruction decode done).

Merge pull request #99 from davidgiven/dtrg-ass 
Bodge together a buildable em22 plat for use with int.
 2018-06-14 10:08:17 +09:00
David Given 519eef933c Merge from trunk. 2018-06-13 21:47:25 +09:00
David Given 31c2ba3f94 File cleanup. 2018-06-13 21:47:08 +09:00
David Given 7eaa235fd1 Bodge the ancient em monitor library into building as a libsys for the em22 
plat. It's completely untested, but it builds and makes e.out executables.
 2018-06-13 21:44:25 +09:00
David Given 13a7abdd69 Rename a function to avoid a clash with an em system call. 2018-06-13 21:34:14 +09:00
David Given 670c7ce96f After finding the em_table documentation, move it somewhere where other people 
can find it.
 2018-06-13 20:58:44 +09:00
David Given 15161ebb35 Remember to always link the libsys and libend. 2018-06-13 20:57:31 +09:00
David Given 7f2ca76663 Expose our custom Lua interpreter to the build system so utility scripts can be 
written in it.

Merge pull request #98 from davidgiven/dtrg-m68k 
Fix sub-word-size type conversions for m68020.
 2018-06-12 14:24:32 +02:00
David Given 3892b7e0e6 Remove bogus conversion from test which was causing failure; you're not allowed 
to do cui or ciu with sizes smaller than a word.
 2018-06-12 21:04:27 +09:00
David Given 6ae38887a7 It appears that the parameter to lol technically has to be word aligned; having 
a non-word aligned parameter is illegal (but most of the toolchain accepts it).
So, word align data structures for em22.

George Koehler a000c62808 Get moncalls.c to compile on OpenBSD. 
Remove some declarations (not all correct) and #include <errno.h>,
<time.h>, and <unistd.h> to get the correct declarations.

Disable mount(2), umount(2), and stime(2) because BSD (around
4.3BSD-Reno) lost compatibility with these Unix v7 functions.
 2018-06-10 19:05:42 -04:00
George Koehler 250777d1ca Rename setmode() to set_mode() to avoid BSD prototype. 
4.4BSD added a non-standard function setmode() to <unistd.h>; its
prototype is not compatible.
 2018-06-10 19:04:51 -04:00
George Koehler 6f9e418f94 Remove extra #include <stdio.h> to fix uint 
From my request at https://github.com/kstenerud/Musashi/pull/31

There was a conflict between Musahi's uint and OpenBSD's uint:

    $ cc -o m68kmake m68kmake.c
    $ ./m68kmake
    $ cc -DM68K_COMPILE_FOR_MAME=0 -c m68kcpu.c

George Koehler 5404dace3a Stop using <X11/Xfuncproto.h> from x86emu. 
The code included <X11/Xfuncproto.h> only for _X_ATTRIBUTE_PRINTF,
which tells some compilers to check the printf format string.  Remove
so ACK doesn't need any X11 headers.

Some machines don't have the X11 headers, or they need a flag like
-I/usr/X11R[67]/include to find them.

Merge pull request #95 from davidgiven/dtrg-b 
Fix occasional weird behaviour causing compilation failures in b.
 2018-06-10 21:22:26 +09:00
David Given 4a249b1bdb Merge. 2018-06-10 20:26:10 +09:00
David Given d623440c77 Add the core of a simple em22 platform. Unfortunately it doesn't work; the old 
em libmon vanished decades ago (or never existed), and also ass appears to have
a different idea of what the em opcodes are to everything else and gets
confused.
 2018-06-10 20:25:48 +09:00
David Given cebb238036 Merge. 2018-06-10 18:09:18 +09:00
David Given 003799f898 Fix table underrun when looking up the character class of the EOF character, 
-1.

Merge pull request #94 from davidgiven/dtrg-ass 
Get int and ass building.
 2018-06-09 22:44:24 +09:00
David Given e7124f3e3f File cleanup. 2018-06-09 21:21:28 +09:00
David Given a12181748b Make ass and int built with clang --- surprisingly easy. 2018-06-09 21:18:50 +09:00
David Given 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.
 2018-06-09 21:13:31 +09:00
David Given d10a594c04 Get ass running --- it's very K&R and almost certainly won't build on clang, 
but it works on gcc.

Merge pull request #93 from davidgiven/dtrg-pc86-2 
Rearrange the tests; don't run unsupported tests on emulators which don't support them.
 2018-06-08 21:40:25 +09:00
David Given 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).

Merge pull request #92 from davidgiven/dtrg-pc86-2 
Replace the qemu pc86 emulator with a custom x86emu-based one.

Merge pull request #91 from davidgiven/dtrg-m68k 
Add a Musashi-based 68020 emulator; use it to run the linux68k tests.
 2018-06-07 13:48:06 +09:00
David Given b9c0e1d964 Dummied out some more system calls --- more tests pass. 2018-06-07 13:12:15 +09:00
David Given 2682c125e0 More real ELF loading and brk handling; more tests pass. 2018-06-07 13:03:36 +09:00
David Given 396795105f Beat the 68k simulator into enough shape that at least *some* of the tests pass. 2018-06-06 22:39:43 +09:00
David Given 4b26f75d23 Hang on, the 68k is big-endian --- I'm extracting words (and bytes) from longs 
incorrectly.
 2018-06-06 12:49:21 +09:00
David Given 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...
 2018-06-05 23:17:22 +09:00
David Given a8802c934b Enable tests for linux68k. 2018-06-05 23:16:34 +09:00
David Given 5034ed1c39 Crudely beat the standard Masushi simulator into working in the ACK framework. 2018-06-05 17:45:00 +09:00
David Given 3f049a4c29 Basic mid now throws an error on out-of-bounds parameters rather than returning 
an uninitialised pointer (and crashing).

Fixes: #54

Fixes: #90
 2018-06-05 09:20:46 +09:00
David Given c6b9446722 Check in the x86emu-based emulator. Sadly, just like the 8086tiny-based 
emulator, FPU instructions aren't supported.
 2018-06-04 16:19:45 +09:00
David Given d908f9cfb2 Modify the pc86 test harness to use 8086tiny instead of qemu. Sadly, some tests fail. 2018-06-03 15:13:43 +02:00
David Given 0eb89d5d95 Add a clean copy of the Musashi emulator. 2018-06-05 17:04:47 +09:00
