416b13fd76 Start factoring out the hardware op code. 2016-09-25 23:29:59 +02:00
David Given
39aa672422 Sort of keep track of registers and register classes. Start walking the 
generated instruction tree --- holy cow, they look like instructions!

bde5792b1a Collapse several rule arrays into one; actually generate the array properly. 2016-09-25 17:14:54 +02:00

67eb21d428 Rename struct insn to struct em (throughout). 2016-09-25 12:29:03 +02:00
David Given
9f78e0b36b Rethink the way patterns are mapped to rules; generate emitters (probably 
badly).

7c028bdd45 We now record the code fragments to be emitted by each rule. 2016-09-25 00:21:46 +02:00

717b77dd0a Instruction selection is so important the file needs a longer name. 2016-09-24 22:50:53 +02:00

629e0ddfc6 Some instruction selection is now happening. 2016-09-24 22:46:08 +02:00

c8fcbe282a More grammar changes. 2016-09-24 19:03:55 +02:00
David Given
2acc4ed29d IR codes are now owned by mcgg; ir terminals are inserted into the table during 
compilation (so you can refer to them).

1516657907 Crudely bolt on mcgg to mcg itself. 2016-09-24 17:20:40 +02:00

6643d39b2c Fix some late-night typo bugs. 2016-09-24 01:09:32 +02:00
David Given
bb9aa030a5 Procedure compilation now happens after the entire EM file has been read in (so 
that we can look inside data blocks which might be defined in the future...
sigh, csa and csb). csa and csb no longer generate invalid IR.

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.

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.

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.

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.

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

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

856eb120b3 Add files which got missed in the initial build pass. 2016-08-20 14:04:17 +02:00

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

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

0d77cb8279 We can build our first C file. 2016-08-07 21:56:53 +02:00

b50dc4214a Add check for undefined variables. Find undefined variables. Fix undefined 
variables.

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.

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.

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.
