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

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

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.

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.

6ce2495aeb Store the EM code up front and build the basic block graph *before* 
generating the IR code. Lots more IR code.

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.

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.

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.
