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.
 2016-10-01 12:17:14 +02:00
David Given 3a973a19f3 Move fatal(), warning() and aprintf() into the new data module (because they're

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.

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 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.

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 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 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 
and pointers were the same size).

 2007-02-24 02:01:57 +00:00

prototyping syscalls itself.

exactly equivalent and standard strchr() and strrchr() functions instead.
 2006-07-23 20:01:02 +00:00
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.
