George Koehler b1d1b5e1f8 Fix bugs with memory allocation in ego. 
cf/cf_loop.c and share/put.c tried to read the next pointer in an
element of a linked list after freeing the element.  ud/ud_copy.c
tried to read beyond the end of the _defs_ array: it only has
_nrexpldefs_ elements, not _nrdefs_ elements.

These bugs caused core dumps on OpenBSD.  Its malloc() put _defs_ near
the end of a page, so reading beyond the end crossed into an unmapped
page.  Its free() wrote junk bytes and changed the next pointer to
0xdfdfdfdfdfdfdfdf.

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 2b6d251dec Fix a fun bug where, every now again, ego would get its temporary files mangled 
and generate invalid calls to the optimisers.

Previously ego would generate a temporary file template that looked like
/tmp/ego.A.BB.XXXXXX, call mktemp() on it to randomise the XXXXXX, and then
replace A and BB with data.

However, it used strrchr to find the A and B. Which would fine, except when
mktemp produced an A or a B in the randomised part...

This code was written on 4 March 1991. I was 16.
 2016-08-22 23:53:01 +02:00
David Given 2a95b1c5e3 Forgot to check a file in. 2016-08-22 22:45:32 +02:00
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.

David Given a42939df50 LED builds now. 2016-08-14 14:40:01 +02:00
David Given 4d24666432 Move util/data into modules/src/em_data, for consistency with the other 
modules.
 2016-08-14 14:09:38 +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 0d77cb8279 We can build our first C file. 2016-08-07 21:56:53 +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 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 1fdc69fb97 cemcom.ansi now builds. 2016-07-19 23:43:14 +02:00
David Given 2d2497c318 ackbuilder rules files now require absolute paths in external variables 
(otherwise commands which change directory don't work).
 2016-07-18 23:16:27 +02:00
David Given bcf3408e36 More stuff builds; almost the C compiler now. 2016-07-14 23:54:13 +02:00
David Given d805052205 All the amisc binaries now build. 2016-06-19 09:32:45 +02:00
David Given 2af8568cc3 First draft at installables; not very satisfactory. make bugs with multiple 
output targets and parallelism?
 2016-06-16 05:26:44 +02:00
David Given 09554cb324 installable works, although it's a bit kludgy. Change the : separator to + 
because : is special in make and non of the others I could think of would work.
 2016-06-14 07:34:14 +02:00

David Given ef8e6e25e0 Fix a whole pile of issues related to the failed attempt to increase 
the number of types of relocation possible in the object file. (Now,
hopefully, working.)

Also change the object serialiser/deserialiser to never try to read or
write raw structures; it's way safer this way and we don't need the
performance boost any more.

George Koehler c8fdcff960 Some fixes for aelflod and aslod. 
Copy rhead() and rsect() from aslod to aelflod, so aelflod can work
for machine with 64-bit long.

In aelflod, fix ELF header so file(1) no longer reports "corrupted
section header size".
 2013-04-24 19:57:23 -04:00
George Koehler 0fc7fd5d33 Prevent segfault when trying to print an error message. 
Use <stdarg.h> to pass arguments correctly, as ack/util/util.c
already uses <stdarg.h> the same way.
 2012-10-24 13:44:50 -04:00
David Given 4349d702fa Change from using platform-specific types to stdint platform-independent types 
when reading the structure header.
 2012-09-27 11:32:40 +01:00
George Koehler 7ef9b79c11 Merge deletion of many undead files. 2012-09-23 15:31:16 -04:00
George Koehler e7c79415b5 Prevent division by zero in aslod. 
rhead() and rsect() had assumed sizeof(long) == 4, but OpenBSD/amd64
has sizeof(long) == 8.  The problem revealed itself when sect->os_lign
became zero, and align() divided by zero.
 2012-09-21 22:51:12 -04:00
George Koehler 0131ca4d46 Delete 689 undead files. 
These files "magically reappeared" after the conversion from CVS to
Mercurial.  The old CVS repository deleted these files but did not
record *when* it deleted these files.  The conversion resurrected these
files because they have no history of deletion.  These files were
probably deleted before year 1995.  The CVS repository begins to record
deletions around 1995.

These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted.  There is no way to fix
this, because the CVS repository provides no dates of deletion.

 2012-09-20 22:26:32 -04:00
George Koehler 96ea0a5903 Fix more functions in util/ack for 64-bit hosts. 
This continues the fix from changeset aabde0589450.  We must use
va_list to forward the arguments, because some of the arguments might
be 64-bit pointers.  A pointer does not fit in an int.
 2012-09-07 16:28:10 -04:00
David Given 6ea172d0d9 Fix a 64-bitness issue (removed some untyped K&R C code that assumed ints
