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

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.

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.

David Given 88bd7ce126 Remove defunct pmfiles.

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.

instead.

David Given 3d5e72e20b Newer versions of GNU Make have a new function which collides with a
variable we're using; change the name of the variable.

David Given e0c121d6e6 Use relocation enumerations rather than hard-coded values for relocation types
