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.

George Koehler b9b3428e01 Build (but don't use) libfp for cpm. 
This library is for software floating point.  The i80 back end has
never implemented floating point, and might not be ready for libfp.
This commit only builds libfp without using it.

I edit first/build.lua and plat/build.lua to allow `ack -c.s`, then
use FP.script to edit the assembly code.  I edit FP.script so it
writes the edited assembly code to stdout, not to the input file.

Merge pull request #69 from kernigh/kernigh-stdc 
use libc assert, strcmp; declare more functions; fewer clang warnings
 2017-11-19 12:00:40 +01:00
George Koehler ac4cbd735e Use libc assert(); fix dependencies; unbreak isduo(). 
Switch from custom assert() to libc assert() in mach/proto/as.
Continue to disable asserts if DEBUG == 0.

This change found a problem in the build system; comm2.y was missing
depedencies on comm0.h and comm1.h.  Add the missing dependencies to
the cppfile rule.  Allow the dependencies by modifying cppfile in
first/build.lua to act like cfile if t.dir is false.

Now that comm2.y gets rebuilt, I must fix the wrong prototype of
yyparse() in comm1.h.

I got unlucky as induo() in comm5.c was reading beyond the end of the
array.  It found an operator "= " ('=' then space) in the garbage, so
it returned a garbage token number, and "VAR = 123" became a syntax
error.  Unbreak induo() by terminating the array.

George Koehler 96e23b3a0f Show tests that @@TIMEDOUT. 
A `set -e` in testdriver.sh caused it to exit early and hide the
output of a @@TIMEDOUT test, so I never saw the @@TIMEDOUT marker.
Then build.lua added a @@FAIL marker.

David Given fd10cf7ac2 Merge from trunk. 2017-08-06 10:42:16 +02:00
David Given 1ea46f6afe Actually tell the user which tests failed. 2017-01-15 22:26:09 +01:00
David Given 3fe285f8f8 Fix some shell issues that would occasionally cause hangs if no tests failed. 2016-12-05 21:06:38 +01:00
David Given 353e2d2842 Typo fix. 2016-12-02 00:18:44 +01:00
David Given 213def9666 Don't fail to build if all tests are skipped. 2016-12-02 00:14:40 +01:00
David Given 3aa0487289 UI tweaks to the test summary. 2016-12-02 00:10:33 +01:00
David Given 467709ff38 Report skipped, failed and timed out tests. 2016-12-02 00:00:31 +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
David Given b5980af06f Linker groups don't work on OSX; go back to the hacky way of simply specifying 
the inputs multiple times, which seems to work.
 2016-11-24 21:03:27 +01:00
David Given e9fe1d70a6 Fix (or at least, work around) an issue with library order. Make sure the Basic 
error symbols are actually defined.
 2016-11-13 13:28:09 +01:00
David Given 84ee75ec07 Merge from default. 2016-11-11 20:17:54 +01:00
David Given e7eb563ee9 Disable gethostid() in the build system Lua; it's unused and doesn't work on 
Haiku.
 2016-11-11 20:16:43 +01:00
David Given 694d1e2deb Merge from default. 2016-10-30 15:59:44 +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 479a4efa4f Use a self-hosted Lua instead of the system one. 2016-10-16 20:07:54 +02:00
David Given 56e13e24e0 Cleanup some stray files. 2016-09-03 19:22:38 +02:00
David Given 1b8df04e58 Add modeline, fix formatting. 2016-09-03 19:17:09 +02:00
David Given de2f99dc1a More documentation. 2016-09-03 19:01:47 +02:00
David Given ea4142daee First half of the ackbuilder documentation. 2016-09-03 01:04:16 +02:00
David Given ff9bf5b08a Makefiles are now slightly less inaccurate. Does actually seem to do sensible 
incremental builds now. I loathe make.
 2016-09-03 00:20:11 +02:00
David Given f67c98e239 Distributions are a pain --- let's not bother any more. Instead, we just tag 
the repository and download a complete snapshot, old and ancient stuff and all.
 2016-09-02 23:00:38 +02:00
David Given 612e38f1c6 Remove the old make-based build system, plus some big chunks of horribly 
obsolete protomake build system.
 2016-09-02 22:17:51 +02:00
David Given 08823a172c filenamesof() an installable now returns all installed files, not just the ones 
at the top level (necessary to make a lot of the dependency stuff work when
using tools which depend on installables).
 2016-08-21 21:55:21 +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 23e8d5af5a Wildcards are allowed to match no files now. 2016-08-20 12:40:00 +02:00
David Given 46bd70380c Filename variables now get passed into ackbuilder on the command line. 2016-08-15 00:47:08 +02:00
David Given 53f043ff40 Backport to Lua 5.1 (because 5.2 on Travis doesn't have luaposix...). 2016-08-14 22:52:57 +02:00
David Given fb2a42a2db installables need to depend on their source files... 2016-08-14 11:25:47 +02:00
David Given 10746f8b97 Add cycle detection, because it was ruining my day. Allow targets to be stored 
in a file called build-<target>.lua to allow better dividing up of build rules
(to break cycles).
 2016-08-14 01:38:36 +02:00
David Given b592c88bdf replace() gets confused if you give it a singleton list as its parameter. 2016-08-12 00:19:30 +02:00
David Given c213602a02 Target lists can now have keyed items ({["foo"] = "+target"); this is 
used by both installable and by clibrary{} to allow headers to be
installed into subdirectories.
 2016-08-08 23:55:23 +02:00
David Given 0d77cb8279 We can build our first C file. 2016-08-07 21:56:53 +02:00
David Given b50dc4214a Add check for undefined variables. Find undefined variables. Fix undefined 
variables.
 2016-08-05 00:01:55 +02:00
David Given 5e84be70fd Massive ackbuilder refactor --- cleaner and more expressive. Lists 
are automatically flattened (leading to better build files), and the
list and filename functions are vastly more orthogonal.
 2016-08-04 23:51:19 +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.
 2016-07-29 00:22:49 +02:00
David Given c6292642c6 Fix a nasty dependency bug where filenamesof() on installables wouldn't 
return any of the installable files (which meant installables were
never considered as dependencies).
 2016-07-29 00:22:22 +02:00
David Given f9c77fca03 Replace the hacky cflags variable with an equally hacky but vastly 
more useful magic vars variable.
 2016-07-27 00:10:15 +02:00
David Given cdeea836f2 Replaced the fairly complex environment code with a much simpler 
emitter object.
 2016-07-26 23:43:31 +02:00
David Given a8a9d1bbfa yacc, ncgg; platform ncg builds now. 2016-07-26 23:35:30 +02:00
David Given bff5c4019c Baby steps towards building a platform --- make the assembler work. 
Add ackbuilder support for C preprocessor files and yacc.
 2016-07-24 00:50:02 +02:00
David Given 2770a83837 More programs, more libraries. src/modules build files are now saner. 2016-07-23 00:30:31 +02:00
David Given 05e3cf286f Saner clibrary dependency and header handling. 2016-07-19 23:42:56 +02:00
David Given b7720c298b Error out if a template expansion returns nil (as it's normally an error). 2016-07-19 23:42:42 +02:00
David Given 2d2497c318 ackbuilder rules files now require absolute paths in external variables 
(otherwise commands which change directory don't work).
