David Given 7ae888b754 Hacky workaround the way the Modula-2 compiler generates non-standard sized 
loads and saves. More opcodes; simplified table using macros.
 2016-10-22 10:48:22 +02:00
David Given f851ab83af Better (and more correct) floating point conversions; fif; various new opcodes. 2016-10-22 00:48:26 +02:00
David Given 4db402f229 Add (pretty crummy) support for register aliases and static pairs of registers. 
We should have enough functionality now for rather buggy 8-bit ints and
doubles. Rework the table and the platform.c to match.
 2016-10-21 23:31:00 +02:00
David Given d6984d60ac Add parsing support for register aliases. 2016-10-20 21:47:28 +02:00
David Given e4fec71f9c Lots more opcodes; better eviction behaviour; better register moves. Lots more 
PowerPC stuff (some working).
 2016-10-19 23:29:05 +02:00

David Given 6a06ce798b Add missing header that was causing builds to fail on Travis. 2016-10-16 17:58:01 +02:00
David Given 9504aec2bd Function termination gets routed through an exit block; we now have prologues 
and epilogues. mcgg now exports some useful data as headers. Start factoring
out some of the architecture-specific bits into an architecture-specific file.
 2016-10-15 18:38:46 +02:00
David Given 5ad3aa8595 Add a pile of new instructions used by Pascal; I'm going to need to think about 
how locals and the local base are handled.
 2016-10-15 13:07:59 +02:00
David Given 517120d0fb Allow asm names for registers which are different from the friendly names shown 
in the tracing (because PowerPC register names are just numbers).
 2016-10-15 11:42:47 +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.
 2016-10-15 01:15:08 +02:00
David Given 98fe70a7de Output register equality constraints work. 2016-10-14 22:17:02 +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 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 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 2198db69b1 Instruction predicates work now. 2016-10-08 11:35:33 +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 7f901aa4d0 We're not using 'allocates' any more; clean up. 2016-10-06 21:33:43 +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 92502901a7 Better management of register data. Add struct hreg. 2016-10-05 21:00:28 +02:00
David Given 8d4186130d Oops --- hadn't updated the nts array for the new child order. 2016-10-04 21:32:28 +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).

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 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.

David Given 3a973a19f3 Move fatal(), warning() and aprintf() into the new data module (because they're

David Given b32883b013 More properly keep track of register classes. 2016-09-29 22:32:43 +02:00
David Given b27758b7de Error check fragment rules which don't emit anything. 2016-09-29 22:14:11 +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 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

 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 bcc74ba18d Stupid stringlist is stupid. Use a proper data structure, properly abstracted 
out (so other things can use it).
 2016-09-25 12:18:39 +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 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).

David Given 1516657907 Crudely bolt on mcgg to mcg itself. 2016-09-24 17:20:40 +02:00
David Given 13132128a1 Parameters are parsed with getopt. Simplify, constify. 2016-09-24 16:59:49 +02:00
David Given 434eafd35d Change the predicate stuff to use costs instead; now you can use when clauses 
on leaves. Remove an iburg premature optimisation (required for above).
 2016-09-24 13:33:59 +02:00
David Given d96ceea08a Lots of exploratory new grammar for instruction definitions and string and 
fragment emission (none of which is hooked up to anything yet).
 2016-09-24 13:08:17 +02:00
David Given 960259f0b0 Add support for labelled tree nodes. 2016-09-24 12:11:30 +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.

George Koehler 9db305b338 Enable the Hall check again, and get powerpc to pass it. 
Upon enabling the check, mach/powerpc/ncg/table fails to build as ncgg
gives many errors of "Previous rule impossible on empty stack".  David
Given reported this problem in 2013:
  https://sourceforge.net/p/tack/mailman/message/30814694/

Commit c93cb69 commented out the error in util/ncgg/cgg.y to disable
the Hall check.  This commit enables it again.  In ncgg, the Hall
check is checking that a rule is possible with an empty fake stack.
It would be possible if ncg can coerce the values from the real stack
to the fake stack.  The powerpc table defined coercions from STACK to
{FS, %a} and {FD, %a}, but the Hall check didn't understand the
coercions and rejected each rule "with FS" or "with FD".

This commit removes the FS and FD tokens and adds a new group of FSREG
registers for single-precision floats, while keeping FREG registers
for double precision.  The registers overlap, with each FSREG
containing one FREG, because it is the same register in PowerPC
hardware.  FS tokens become FSREG registers and FD tokens become FREG
registers.  The Hall check understands the coercions from STACK to
FSREG and FREG.  The idea to define separate but overlapping registers
comes from the PDP-11 table (mach/pdp/ncg/table).

This commit also removes F0 from the FREG group.  This is my attempt
to keep F0 off the fake stack, because one of the stacking rules uses
F0 as a scratch register (FSCRATCH).
 2016-09-18 15:08:55 -04:00
George Koehler 9ec2918e14 In ncgg, increase MAXREGS from 80 to 200. 
I need this to add more registers to powerpc.

George Koehler ff4a7e3d2a Merge branch 'default' into kernigh-linuxppc 2016-09-17 18:15:54 -04:00
David Given 80cb6ba927 Eliminate the RELOH2 relocation, as it never worked --- the address would be 
calculated incorrectly because of overflow errors.

Replace it with an extended RELOPPC relocation which understands addis/ori
pairs; add an la pseudoop to the assembler which generates these and the
appropriate relocation. Make good.

George Koehler b1d1b5e1f8 Fix bugs with memory allocation in ego. 
cf/cf_loop.c and share/put.c tried to read the next pointer in an
element of a linked list after freeing the element.  ud/ud_copy.c
tried to read beyond the end of the _defs_ array: it only has
_nrexpldefs_ elements, not _nrdefs_ elements.

These bugs caused core dumps on OpenBSD.  Its malloc() put _defs_ near
the end of a page, so reading beyond the end crossed into an unmapped
page.  Its free() wrote junk bytes and changed the next pointer to
0xdfdfdfdfdfdfdfdf.

David Given f67c98e239 Distributions are a pain --- let's not bother any more. Instead, we just tag

obsolete protomake build system.
 2016-09-02 22:17:51 +02:00
David Given 2b6d251dec Fix a fun bug where, every now again, ego would get its temporary files mangled 
and generate invalid calls to the optimisers.

Previously ego would generate a temporary file template that looked like
/tmp/ego.A.BB.XXXXXX, call mktemp() on it to randomise the XXXXXX, and then
replace A and BB with data.

However, it used strrchr to find the A and B. Which would fine, except when
mktemp produced an A or a B in the randomised part...

This code was written on 4 March 1991. I was 16.

David Given 2a95b1c5e3 Forgot to check a file in. 2016-08-22 22:45:32 +02:00
David Given 5bae29a00c ego now builds and is used. 
This needed lots of refactoring to ego --- not all platforms have ego descr
files, and ego will just crash if you invoke it without one. I think originally
it was never intended that these platforms would be used at -O2 or above.

Plats now only specify the ego descr file if they have one.

George Koehler c8fdcff960 Some fixes for aelflod and aslod. 
Copy rhead() and rsect() from aslod to aelflod, so aelflod can work
for machine with 64-bit long.

In aelflod, fix ELF header so file(1) no longer reports "corrupted
section header size".
 2013-04-24 19:57:23 -04:00
George Koehler 0fc7fd5d33 Prevent segfault when trying to print an error message. 
Use <stdarg.h> to pass arguments correctly, as ack/util/util.c
already uses <stdarg.h> the same way.

David Given 4349d702fa Change from using platform-specific types to stdint platform-independent types 
when reading the structure header.

George Koehler e7c79415b5 Prevent division by zero in aslod. 
rhead() and rsect() had assumed sizeof(long) == 4, but OpenBSD/amd64
has sizeof(long) == 8.  The problem revealed itself when sect->os_lign
became zero, and align() divided by zero.
 2012-09-21 22:51:12 -04:00
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.

George Koehler 96ea0a5903 Fix more functions in util/ack for 64-bit hosts. 
This continues the fix from changeset aabde0589450.  We must use
va_list to forward the arguments, because some of the arguments might
be 64-bit pointers.  A pointer does not fit in an int.
 2012-09-07 16:28:10 -04:00
David Given 6ea172d0d9 Fix a 64-bitness issue (removed some untyped K&R C code that assumed ints

dtrg 05d3be79cd Removed a really unpleasant test for whether a pointer points at a string 
constant or not by comparing it with 'end', which presumably points at
the top of the BSS. In fact, on Linux it evaluates to NULL, and on OSX it
doesn't exist at all, so it appears to be unnecessary.
 2006-07-23 19:38:13 +00:00
dtrg 345f4c8978 Modified to avoid creating a zero-length iargs array, which some compilers 
(OSX) do not create a symbol for.
