David Given b2ddf12473 Some more opcodes. 2016-10-15 11:22:40 +02:00
David Given bb17aea73a You can now mark a register as corrupting a certain register class; calls work,
or at least look like they work. The bad news is that the register allocator
has a rare talent for putting things in the wrong register.

David Given bb53a7fb51 Fix stupid issue where hop output registers were being overwritten, leading to
invalid SSA form.

David Given 98fe70a7de Output register equality constraints work. 2016-10-14 22:17:02 +02:00
David Given 216ff5cc43 Make loads and stores in the table nicer; fix a place where it looked like it
was working but only accidentally.
2016-10-12 23:12:53 +02:00
David Given f06b51c981 Keep track of register types as well as attributes --- the type being how we
find new registers when evicting values. Input constraints work (they were
being ignored before). Various bug fixing so they actually work.
2016-10-12 22:58:46 +02:00
David Given 4723a1442f Add code to remove unused phis, converting to pruned SSA form, to avoid
confusing the register allocator later.
2016-10-12 21:50:12 +02:00
David Given df239b3f90 Don't allow the same IR to be added to the sequence list more than once
(sometimes happens because op_dup, but makes no sense).
2016-10-12 00:45:36 +02:00
David Given 96dffd2007 Clean up the allocator a bit, in preparation for making it lots more
complicated; no semantic changes.
2016-10-11 23:17:30 +02:00
David Given 668cccdff1 A few more opcodes. 2016-10-11 00:29:18 +02:00
David Given 2be1c51885 A little fiddling with store instructions. The PowerPC is not friendly to
iburg.
2016-10-11 00:23:35 +02:00
David Given e93c58dc8d Refactored the way hops are rendered; add support for emitting code (although
with no prologue or epilogue yet).
2016-10-11 00:12:11 +02:00
David Given 92bd1ac5f4 Register allocator now gets all the way through all of my test file without
crashing (albeit with register moves and swaps stubbed out). Correct code? Who
knows.
2016-10-10 23:19:46 +02:00
David Given a4d06d1795 D'oh, need multiple passes over the edge splitter in order to properly find all
cases.
2016-10-10 23:18:37 +02:00
David Given fac12aae32 Calculate phi congruency groups; use them to solve the
importing-hreg-from-the-future problem (probably poorly).
2016-10-09 22:04:20 +02:00
David Given 23c3575f0f The register allocator now makes a spirited attempt to honour register
attributes when allocating. Unfortunately, backward edges don't work (because
the limited def-use chain stuff doesn't work across basic blocks). Needs more
thought.
2016-10-09 15:09:34 +02:00
David Given 38de688c5a Floating point promotion was broken since the IR float change. Fix. 2016-10-09 15:08:03 +02:00
David Given 36cddd6afb Add some more opcodes; rearrange the registers to be more PowerPC-friendly. 2016-10-09 14:45:13 +02:00
David Given cfe5312fcc Predicates can now take numeric arguments. The PowerPC predicates have been
turned into generic ones (as they'll be useful everywhere). Node arguments for
predicates require the '%' prefix for consistency. Hex numbers are permitted.
2016-10-09 12:32:36 +02:00
David Given d75cc0a663 Basic register allocation works! 2016-10-08 23:32:54 +02:00
David Given 637aeed70a Only allocate an output vreg if the instruction actually wants one. 2016-10-08 12:15:21 +02:00
David Given 2198db69b1 Instruction predicates work now. 2016-10-08 11:35:33 +02:00
David Given 9ebf731335 Minor cleanup. 2016-10-08 11:07:28 +02:00
David Given 9db902314b Fix bug where pushes were being placed in the wrong blocks. 2016-10-08 10:21:24 +02:00
George Koehler 65c2a8a0ae Remove stackadjust and stackoffset() from ncg.
This feature has never been used since its introduction, more than 3
years ago, in David Given's commit c93cb69 of May 8, 2013.  The commit
was for "PowerPC and M68K work".  I am not undoing the entire commit.
I am only removing the stackadjust and stackoffset() feature.

This commit removes the feature from my branch kernigh-linuxppc.  This
removal includes the mach/proto/ncg parts.  The default branch already
removed most of the feature, but kept the mach/proto/ncg parts.  That
removal happened in commit 81778b6 of May 13, 2013 (which was a merge;
git diff af0dede 81778b6).  The branch dtrg-experimental-powerpc
merged the default branch but without the removal.  That merge was
commit 4703db0f of Sep 15, 2016 (git diff 8c94b13 4703db0).  My branch
kernigh-linuxppc is off branch dtrg-experimental-powerpc, so I can no
longer get the removal by merging default.

David Given described the stackadjust feature in
  https://sourceforge.net/p/tack/mailman/message/30814691/

The instruction stackadjust would add a value to the offset, and the
function stackoffset() would return this offset.  One would use this
to track sp - fp, then omit the frame pointer by not keeping fp in a
register.
2016-10-07 20:52:13 -04:00
David Given 4e49830e09 Overhaul of everything phi related; critical edge splitting now happens before
anything SSA happens; liveness calculations now look like they might be
working.
2016-10-08 00:21:23 +02:00
David Given ee93389c5f Refactor the cfg and dominance stuff to make it a lot nicer. 2016-10-06 21:34:21 +02:00
David Given d20b63dc94 The register allocator is really a pass, so arrange the code like one. 2016-10-05 23:55:38 +02:00
David Given 87e004e4a9 Warning fix. 2016-10-05 23:55:04 +02:00
David Given 21034c0d65 No, dammit, for register allocation I need to walk the blocks in *dominance*
order. Since the dominance tree has changed when I fiddled with the graph, I
need to recompute it, so factor it out of the SSA pass. Code is uglier than I'd
like but at least the RET statement goes last in the generated code now.
2016-10-05 23:52:54 +02:00
David Given d95c75dfd7 Allowing an input filename on the command line makes debuggers happy. (Then we
don't need to redirect stdin.)
2016-10-05 23:24:29 +02:00
David Given 88fb231d6e Better constraint syntax; mcgg now passes register usage information up to mcg;
mcg can track individual hop inputs and outputs (needed for live range
analysis!); the register allocator now puts the basic blocks into the right
order in preparation for live range analysis.
2016-10-05 22:56:25 +02:00
David Given 7a6fc7a72b Made sure that all files end in vim magic. 2016-10-05 21:07:29 +02:00
David Given 92502901a7 Better management of register data. Add struct hreg. 2016-10-05 21:00:28 +02:00
David Given ac62c34e19 Add a pass to do critical edge splitting. 2016-10-04 23:42:00 +02:00
David Given 8fedf5a0a8 Added support for the op_bXX conditional branch instructions. 2016-10-04 23:28:16 +02:00
David Given 249855ed23 Fix the horror of the startup code; now uses getopt and stuff and the debug
flags can be set as an option.
2016-10-04 22:36:01 +02:00
David Given ac063a6f54 Remove unused variable (reduce memory usage by 1/10). 2016-10-04 22:35:08 +02:00
David Given c6f576f758 Bodge in enough phi support to let the instruction generator complete on basic
programs.
2016-10-04 21:58:31 +02:00
David Given e13ff5be31 Don't allocate new vregs for REG and NOP --- a bit hacky, but suppresses stray
movs very effectively.
2016-10-04 21:29:03 +02:00
David Given bd28bddb92 Massive rewrite of how emitters and the instruction selector works, after I
realised that the existing approach wasn't working. Now, hopefully, tracks the
instruction trees generated during selection properly.
2016-10-04 00:16:06 +02:00
David Given 68f98cbad7 Instruction selection now happens on a shadow tree, rather than on the IR tree
itself. Currently it's semantically the same but the implementation is cleaner.
2016-10-03 20:52:36 +02:00
David Given 288ee56203 Get quite a long way towards basic output-register equality constraints (needed
to make special nodes like NOP work properly). Realise that the way I'm dealing
with the instruction selector is all wrong; I need to physically copy chunks of
tree to give to burg (so I can terminate them correctly).
2016-10-02 23:25:54 +02:00
David Given 3aa30e50d1 Come up with a syntax for register constraints. 2016-10-02 21:51:25 +02:00
David Given c079e97492 Perform SSA conversion of locals. Much, *much* better code now, at least
inasmuch as it looks better before register allocation. Basic blocks now know
their own successors and predecessors (after a certain point in the IR
processing).
2016-10-02 17:50:34 +02:00
David Given 79d4ab1d96 Add zrl opcode. Keep track of local sizes as well as offsets. 2016-10-02 16:08:46 +02:00
David Given bf73fcdb64 Add inl and del opcodes. 2016-10-02 14:44:21 +02:00
David Given b298c27c63 Refactor mcg.h as it's getting a bit big; keep track of register variables. 2016-10-02 00:30:33 +02:00
David Given 06059233da Make betterer. 2016-10-01 23:41:45 +02:00
David Given 65e75be42d Fix edge case where leftover pushes would occasionally cause infinite loops in
the analysis.
2016-10-01 23:41:35 +02:00
David Given 73d7e89c32 Show expression trees correctly. 2016-10-01 23:41:03 +02:00
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

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

Add ackbuilder support for C preprocessor files and yacc.

David Given 07453d184a Top, topgen, aelflod. Moved the libraries back into the platform-specific
directories --- wrangling descr files was too hard. C programs can be built
for cpm, pc86, linux386, linux68k!

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.

dtrg fc44fe2185 Properly handles files ending in a partial line. 2008-03-20 22:50:50 +00:00
dtrg 663f4f2fb5 Cleaned up a bit and made work with the new platform architecture. 2007-04-29 23:03:24 +00:00
dtrg daee8da3c4 yacc source files are now run through the ANSI C preprocessor, not the K&R one. 2007-04-21 22:55:59 +00:00
dtrg b611731ec3 Updated .distr files for the new release. 2007-02-25 12:51:55 +00:00
dtrg 5c5f711cbb Done a major overhaul of the way target include files are installed and
how platform libraries are built. The ARCH pm variable has now been
renamed PLATFORM (which is more accurate) and a different ARCH
variable added, which represents the CPU family rather than the
hardware platform.

dtrg db0b628497 Removed a definition of 'struct label' as 'label_t', as it clashes with
a common Posix extension on BSD systems.
