David Given 3474e20274 Deal with malformed mes instructions emitted by ego. 2016-10-01 23:13:39 +02:00
David Given a3cfe6047f More rigorous dealing of IR groups; no need for is_generated and is_root any 
more (but now passes are required to set IR roots properly when changing
instructions).
 2016-10-01 22:58:29 +02:00
David Given 21898f784a We're going to need some type inference after all, I think. Let's do a little 
for now and see how it goes.
 2016-10-01 19:10:22 +02:00
David Given 91e277e046 Predicates work; we now have prefers and requires clauses. Predicates must be 
functions. Not convinced that semantic types are actually working --- there are
still problems with earlier statements leaving things in the wrong registers.
 2016-10-01 13:56:52 +02:00
David Given 4a3a9a98dc It doesn't really make a lot of sense to have BURG nonterminal names different 
to register classes, so combine them. Refactor the map code.
 2016-10-01 12:17:14 +02:00
David Given 3a973a19f3 Move fatal(), warning() and aprintf() into the new data module (because they're 
really useful).
 2016-09-30 19:10:30 +02:00
David Given 0d246c0d73 Much better handling of fragments (no run-time code needed to distinguish them 
from registers) and better handling of individual hops within a paragraph ---
no more ghastly hacks to try and distinguish the input from the output.
 2016-09-29 22:06:04 +02:00
David Given a0131fdb47 You know what, the type inference stuff is a complete red herring. What this 
actually needs is a more intelligent register allocator. So, remove the type
inference.
 2016-09-29 19:58:02 +02:00
David Given 4572f1b774 Actually, I don't need vregs: hops work just as well. Particularly if I 
restructure things so that I don't need to walk the blasted ir / burg tree
every time I look at an instruction.
 2016-09-27 23:38:47 +02:00
David Given e77c5164cf Fleshed out hops and vregs. The result is almost looking like code now --- 
uncanny.
 2016-09-27 00:19:45 +02:00
David Given f552c9c7c6 Move map into the data module. 2016-09-26 23:03:04 +02:00
David Given c4b8e00ae2 Revamp the array module not to use nasty macros any more. Slightly more verbose 
to use, but definitely cleaner.
 2016-09-26 22:48:58 +02:00
David Given 3671892c34 Move the array library into the data module. 2016-09-26 22:24:49 +02:00
David Given cc176e5183 Keep more data around about ir instructions. Implement a half-baked type 
inference routine to propagate information about floats up the tree, so we know
whether to put floats into special registers as early as possible.
 2016-09-26 22:12:46 +02:00
David Given 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!
 2016-09-25 22:17:14 +02:00
David Given bde5792b1a Collapse several rule arrays into one; actually generate the array properly. 2016-09-25 17:14:54 +02:00
David Given 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).
 2016-09-25 11:49:51 +02:00
David Given 7c028bdd45 We now record the code fragments to be emitted by each rule. 2016-09-25 00:21:46 +02:00
David Given 717b77dd0a Instruction selection is so important the file needs a longer name. 2016-09-24 22:50:53 +02:00
David Given 629e0ddfc6 Some instruction selection is now happening. 2016-09-24 22:46:08 +02:00
David Given 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).
 2016-09-24 18:31:35 +02:00
David Given 1516657907 Crudely bolt on mcgg to mcg itself. 2016-09-24 17:20:40 +02:00
David Given 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.
 2016-09-24 01:04:00 +02:00
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.
 2016-09-23 23:59:15 +02:00
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 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 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 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.

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 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.

hardware platform.
