David Given 74d166ef9a Get the pdp7 plat working; remove the leading-underscore syscalls. 2018-06-23 15:18:26 +02:00
David Given 3e40374297 Made the rpi platform work with the new libc layout. 2018-06-23 13:05:27 +02:00
David Given dbb2062d03 Made pc86 work with the new libc. 2018-06-23 12:59:40 +02:00
David Given 680b4071b7 Made the two OSX platforms work with the new libc layout. 2018-06-23 12:55:59 +02:00
David Given b727b7affd Make linuxppc work. 2018-06-23 12:41:54 +02:00
David Given b267b56ad9 Made linux68k work; commoned up all the generic linux includes. 2018-06-23 12:35:17 +02:00
David Given 66815ff987 Make linux386 work with the new libc layout. 2018-06-23 12:13:33 +02:00
David Given 32c881474e Create a basic and probably wrong common unistd.h, which replaces the plat one. 
Made this work with cpm (but nothing else yet).
 2018-06-23 11:46:55 +02:00
David Given b21c099a57 Get the em libc working again: remove the modula-2 termcap library, as it's a 
straight copy of the libc one and having two symbols defined at once gets ass
upset.
 2018-06-22 23:17:14 +02:00
David Given c0276416d8 Move some more libc functions into core. 2018-06-22 22:20:02 +02:00
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 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.
 2018-06-09 14:10:45 +09:00
David Given a8802c934b Enable tests for linux68k. 2018-06-05 23:16:34 +09:00
David Given 5d292a0a36 Typo fix. 2018-06-02 21:48:18 +02:00
David Given 5a886787d3 Honour CFLAGS set in the Makefile. 2018-06-02 21:30:52 +02:00
George Koehler 4a3b7be795 Use ack -mcpm -fp for mandelbrot.c, startrek.c 
Add a variable %{ackldflags} so I can pass `-fp`.  This change seems
to cause the build to relink every ackprogram, because the link now
needs to use %{ackldflags} even if the flags are empty.

mandelbrot_c_cpm runs in YAZE-AG; startrek_c_cpm doesn't run because
it doesn't fit in the 16-bit address space.

David Given 4b5a7fee14 Made the cgg and the cg code generator work; use this to beat the PDP/11 
backend into shape. It now generates binaries --- no idea whether they work or
not.

David Given 5f6a773649 Turn of qemuppc for now; it's crashing on Travis builds. 2017-08-06 13:48:01 +02:00
David Given e50f4be710 Merge from default. 2016-12-26 19:44:48 +00:00
David Given 62edb90641 Convert the inn test to work with the test library and not import InOut; it now 
runs on qemuppc again. Reenable qemuppc tests.
 2016-12-11 23:06:37 +01:00
David Given 67e7d226ad Disable qemuppc tests; turns out qemu-system-ppc won't load more than the first 
4kB of a kernel...
 2016-12-06 22:06:17 +01:00
David Given 3cce93586f Merge branch 'pr-osx' of https://github.com/kernigh/ack into kernigh-pr-osx 2016-12-05 20:14:54 +01:00
David Given 07e654d6e3 Merge from default. 2016-12-02 00:25:50 +01:00
David Given 8c99e2b7ad Run all tests, even the ones which fail, and emit a test summary right at the 
end of the build (and fail then).
 2016-12-01 23:03:30 +01:00
George Koehler ecdfb61c9d Merge branch 'default' into kernigh-osx 
This brings in David Given's PowerPC changes, including the addition
of the modern code generator (mcg) for PowerPC.

Resolve minor conflicts in top build.lua and util/led/main.c

David Given cfc723250f Initial EM-ification; start threading word size stuff through the code. 2016-11-27 11:58:59 +01:00
David Given 98c761d5c0 Enable tests for linux386 via qemu-i386. 2016-11-26 11:58:02 +01:00
David Given cf33bd6cc4 Enable tests for linuxppc via qemu-ppc. 2016-11-26 11:56:17 +01:00
David Given 8a58614aef Rework the tests to run on pc86; lots of test fixes for the brk() test, which 
was nearly useless; lots of fixes to qemuppc and pc86 sbrk(), which was broken;
change the pc86 console to echo output to the serial port (needed for running
tests on qemu).
 2016-11-26 11:23:25 +01:00
David Given 6a4f465f53 Add a rather bodged test framework for the qemuppc plat, which only runs if the 
qemu-system-ppc emulator is installed.
 2016-11-13 13:37:22 +01:00
David Given 48e74f46fc Add the very experimental qemuppc plat, intended to generate minimal images 
which can be emulated using qemu (for, hopefully, a test suite). Currently it
generates images which won't run because there's no RAM.
 2016-11-12 19:20:58 +01:00
David Given 5f0164db62 Bolt mcg into the PowerPC backend. It doesn't build yet, but it is generating 
*some* code.
 2016-10-17 00:06:06 +02:00
David Given d539389e81 Merge in the unfinished PowerPC branch. 2016-10-16 22:38:27 +02:00
George Koehler 02fb480217 Commit a preview of osx386 and osxppc as new platforms. 
These produce Mach-o executables for Mac OS X on Intel or PowerPC
processors.  Our code generator for PowerPC (mach/powerpc) still has
bugs.  Some examples seem to run, but startrek crashes.  Our code
generator for Intel (mach/i386) is better.

There is a problem with job control.  If you run paranoia or startrek,
then suspend the job (^Z) and resume it ('fg' in bash), then read(2)
might fail with EINTR.

David Given 45a950571d Mostly add support for the experimental and largely broken linuxppc platform. 
(Doesn't quite build.)

David Given 5bae29a00c ego now builds and is used. 
This needed lots of refactoring to ego --- not all platforms have ego descr
files, and ego will just crash if you invoke it without one. I think originally
it was never intended that these platforms would be used at -O2 or above.

Plats now only specify the ego descr file if they have one.
 2016-08-21 22:01:19 +02:00
David Given 1a7b4f8729 Build the examples when doing a normal build; this exercises the compiler as a 
whole and is one step further towards a proper test suite.
 2016-08-20 14:05:24 +02:00
David Given 204f932ed2 Raspberry Pi backend now builds. 2016-08-20 12:40:13 +02:00
David Given a42939df50 LED builds now. 2016-08-14 14:40:01 +02:00

David Given f253b6a169 linux386 builds. Also, forgot to turn back on the language runtimes. 2016-08-14 10:37:55 +02:00
David Given 262c5fedcf Biggish refactor to break cycles; my build rules were full of them. cpm builds, 
which requires top and topgen.
 2016-08-14 01:39:40 +02:00
David Given e770d09dc8 Pascal compiler builds. 2016-08-13 13:03:06 +02:00
David Given 8e869b56e7 The Modula-2 compiler now builds. 2016-08-13 00:02:21 +02:00
David Given 7c60c27302 The Basic compiler works now. 2016-08-12 00:19:51 +02:00
David Given 0d77cb8279 We can build our first C file. 2016-08-07 21:56:53 +02:00
David Given b2bb4ce3b2 Builds libend (the simplest library). Becoming obvious I need to rework the way 
ackbuilder deals with lists.
 2016-07-30 00:39:22 +02:00
David Given 363d13cc2f C preprocessor; tabgen; now the pc86 boot.s builds using the ack 
toolchain.
