David Given ab7002c0ee All the Linux include directories are the same, so common them all out into a 
single one, like OSX.

Merge pull request #96 from kernigh/kernigh-emu-1 
Fixes to build emulators, ass, int on OpenBSD
 2018-06-20 22:30:01 +02:00
David Given 698613cd7d Turns out that the compiler needs access to the libpc headers too; refactor 
into a separate target to avoid build loops and make it work.
 2018-06-18 22:17:38 +02:00
David Given 11854f4dfe Ansify and warning fix. 2018-06-17 22:30:27 +02:00

Merge pull request #102 from davidgiven/dtrg-powerpc 
Add a PowerPC simulator for running the tests.
 2018-06-17 11:45:26 +02:00
David Given 89e8956bb2 Fix edge case in rlwnm when the mask is 32 bits wide. All tests now pass. 2018-06-17 11:00:01 +02:00
David Given 7ec9f54679 Turns out that andi and andis only have . forms. Fixed; another test passes. 2018-06-17 10:43:39 +02:00
David Given 78eaf836be Turns out I was returning values from syscalls in the wrong register; fixed. 
More tests pass.
 2018-06-17 10:22:20 +02:00
David Given ab660a44e9 Lots of floating point, bugfixes, and system calls. Most of the tests pass now. 2018-06-17 09:24:01 +02:00
David Given 67efbb5f7f Do a bit of floating point stuff; added brk(); fixed a horrible bug where 
stores with 16-bit displacements were storing the register number and not the
contents of the register.
 2018-06-16 22:55:23 +02:00
David Given 5d7cdd2c67 Fix a setcr0 bug which was trashing the condition register; some system 
calls are now implemented. A few tests more-or-less pass (but crash on
exit).

Merge pull request #100 from kernigh/kernigh-pdp 
Two fixes for ack -mpdpv7
 2018-06-15 15:40:24 +09:00
George Koehler 5db312a1c0 Prevent crash in isatty() 
The existing code allocated 2 bytes (char*), but gtty() needs 6 bytes
(struct sgttyb), so isatty() smashed the stack and corrupted its
return address, probably causing SIGBUS or SIGSEGV.

Fix by switching to TIOCGETD, which needs 2 bytes.  TIOCGETD isn't in
the manual for tty(4), but does appear in
https://minnie.tuhs.org//cgi-bin/utree.pl?file=V7/usr/sys/dev/tty.c

This fixes hilo_c.pdpv7 and hilo_mod.pdpv7 in simh-pdp11.
 2018-06-15 00:48:29 -04:00
George Koehler 5de5611c24 Use 2-byte alignment in pdpv7 to prevent SIGBUS. 
Change the alignment in C structs (wa, pa, sa, and so on) from 1 to 2
bytes.  This prevents the SIGBUS when PDP-11 Unix V7 catches the
misalignment.  This fixes hilo_p.pdpv7 in simh-pdp11.

Change ALIGN to document that sections have 2-byte alignment.  This
change should have no effect, because the sections only contain 2-byte
values.

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).
 2018-06-14 03:07:36 -07:00
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 15161ebb35 Remember to always link the libsys and libend. 2018-06-13 20:57:31 +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 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.
 2018-06-10 16:00:23 -04:00
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 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).
 2018-06-08 15:59:04 +09:00
David Given 1d4ddb939d Merge from trunk. 2018-06-08 00:05:50 +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 5034ed1c39 Crudely beat the standard Masushi simulator into working in the ACK framework. 2018-06-05 17:45:00 +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 0eb89d5d95 Add a clean copy of the Musashi emulator. 2018-06-05 17:04:47 +09:00
David Given 9132641100 Add the pc86emu skeleton. 2018-06-03 08:24:21 -07:00
