David Given d1cdb07719 Realise that the libc core can safely call other libc core functions, even if 
they're not defined in the core: so putw() can call stdio stuff, for example.
So the earlier concept of pureness isn't necessary. Rename accordingly.

Merge pull request #103 from davidgiven/dtrg-warnings 
Fix a lot of warnings.
 2018-06-18 22:31:35 +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
David Given 5784f5fabe Run C files through clang-format. 2018-06-17 16:11:29 +02:00
David Given 9ede428e3c Use cproto to extract all the prototypes. 2018-06-17 16:10:57 +02:00
David Given 9947e7ac63 Added a pc.h to contain libpc prototypes; some ansification. 2018-06-17 15:54:18 +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).

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:

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.

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.
