George Koehler 9ec2918e14 In ncgg, increase MAXREGS from 80 to 200.
I need this to add more registers to powerpc.

David Given 80cb6ba927 Eliminate the RELOH2 relocation, as it never worked --- the address would be
calculated incorrectly because of overflow errors.

Replace it with an extended RELOPPC relocation which understands addis/ori
pairs; add an la pseudoop to the assembler which generates these and the
appropriate relocation. Make good.

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.

David Given 612e38f1c6 Remove the old make-based build system, plus some big chunks of horribly
obsolete protomake build system.

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.

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 4d24666432 Move util/data into modules/src/em_data, for consistency with the other
modules.

David Given 262c5fedcf Biggish refactor to break cycles; my build rules were full of them. cpm builds,
which requires top and topgen.

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.

David Given 363d13cc2f C preprocessor; tabgen; now the pc86 boot.s builds using the ack

David Given 2d2497c318 ackbuilder rules files now require absolute paths in external variables
(otherwise commands which change directory don't work).

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.

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.
