David Given ed67d427c9 Replaced the block splicer with a trivial block eliminator (which rewrites 
jumps to blocks which contain only a jump). Don't bother storing the bb graph
in the ir nodes; we can find it on demand by walking the tree instead ---
slower, but much easier to understand and more robust. Added a terrible map
library.

David Given f8bbf9e87d Each pass now lives in its own source file; much cleaner. 2016-09-23 21:07:16 +02:00
David Given 9077baa850 Add a bodged in algorithm for converting basic block communication from stacked 
variables to SSA. Also add dead block removal and block splicing. IR code is
much better now.
 2016-09-22 23:19:29 +02:00
David Given 6a74cb2e11 Tracing cleanup. Simplified the IR code. Some more opcodes. 2016-09-22 00:15:48 +02:00
David Given 4546dd5f22 Massive grammar overhaul and refactor. Hacked in support for predicates, where 
instructions can be turned on and off based on their parameters. New lexer
using a lexer. Now quite a lot of the way towards being a real instruction
selector.
 2016-09-21 00:43:10 +02:00
David Given 36d7d1ee4e Create hacky fake basic blocks for data fragments, used to track which 
instruction labels descriptor blocks refer to; this allows csa and csb to know
where they're going.
 2016-09-20 00:19:39 +02:00
David Given dcba03646b Treebuilder now gets to the bottom of my test file, merrily generating 
(probably horribly broken) IR.
 2016-09-19 23:30:41 +02:00
David Given 6ce2495aeb Store the EM code up front and build the basic block graph *before* 
generating the IR code. Lots more IR code.
 2016-09-19 23:06:59 +02:00
David Given 176cd7365c Archival checking of the half-written IR treebuilder. 2016-09-18 23:24:54 +02:00
David Given 24380e2a93 Abstract out the EM reader; skeleton of the tree builder. 2016-09-18 00:02:16 +02:00
David Given 2eee391aef Basic skeleton of em parser. 2016-09-17 22:21:47 +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 856eb120b3 Add files which got missed in the initial build pass. 2016-08-20 14:04:17 +02:00
David Given 204f932ed2 Raspberry Pi backend now builds. 2016-08-20 12:40:13 +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 38fa6941d5 linux68k builds now. 2016-08-14 11:34:18 +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 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 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 88bd7ce126 Remove defunct pmfiles.

 2016-06-03 13:56:50 +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.

David Given c5018d7088 64-bit-ify (adhoc varargs are evil). 2015-03-23 00:07:59 +01:00
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 
(these were causing problems due to the enumeration values having changed).
