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).

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).

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
George Koehler ce5faba919 Remove .linenumber and .filename; use hol0 and hol0+4. 
We need this because some .e files in lang/ are using 'loe 0' and 'lae
4' to load the line number from hol0 and filename from hol0+4.
 2016-09-30 13:40:36 -04:00
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
George Koehler e22c8881e7 Add a rule for sdl ldl $1==$2 to work around a bug. 
In our powerpc table, sdl fails to kill the old value of the local.
This is a bug, because a later ldl can load the old value instead of
the newly stored value.  By rewriting "sdl 0" "ldl 0" as "dup 8" "sdl
0", the newly added rule works around the bug, but only when the ldl
is immediately after the sdl.

This rule improves code that uses double-precision floating point.
The output of printf("%f", 6.0) in C changes from all zero digits to
"6000000" but still doesn't print the decimal point.  The result of
atof("-123.456") becomes correct.  In startrek, I can now move the
Enterprise, but I still can't fire phasers without crashing the game.

We already have a rule for stl lol $1==$2.  We had two copies of the
rule, so I am deleting the second copy.
 2016-09-30 11:50:50 -04:00
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
George Koehler 6ae415d48b Rewrite fef 8 in powerpc assembly. 
In EM, fef splits a float into exponent and fraction.  The old C code,
given an infinite float, got stuck in an infinite loop.  The new
assembly code doesn't loop; it extracts the IEEE exponent.
 2016-09-29 15:52:54 -04:00
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
George Koehler a71eee3914 For "pat ass", move fake stack to real stack before adjusting SP. 
This fixes code that tried to "addi SP, SP, 4" to drop a value that
was in a register, not on the real stack.

Add a rule to optimize "asp 4" (which becomes "loc 4" "ass") when
the value being dropped is already in a GPR.
 2016-09-28 00:13:35 -04:00
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
George Koehler 1e3dde915a Remove the "invalid" stacking rule. 
When ncg fell back on this rule, it did emit the string "invalid" in
the assembly code and caused a syntax error in the assembler.

Adjust the stacking rules so we can stack LOCAL, CONST, and LABEL
without falling back on the "invalid" rule, and so we can stack them
when we have no free register except the scratch register.
 2016-09-27 16:46:11 -04:00
David Given e77c5164cf Fleshed out hops and vregs. The result is almost looking like code now --- 
uncanny.

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.

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 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
George Koehler 5b69777647 Rename our pseudo-opcode 'la' to 'li32'. 
GNU as has "la %r4,8(%r3)" as an alias for "addi %r4,%r3,8", meaning
to load the address of the thing at 8(%r3).  Our 'la', now 'li32',
makes an addis/ori pair to load an immediate 32-bit value.  For
example, "li32 r4,23456789" loads a big number.
 2016-09-18 17:03:23 -04:00
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 03b067e1d5 Add the missing .lar4 and .sar4 for powerpc. 
Inspired by the sparc code (mach/sparc/libem/lar.s).  My powerpc code
might still have bugs, but it's enough for examples/hilo.mod to work.

May need to 'make clean' or touch a build.lua file, so ackbuilder can
notice the new lar4.s and sar4.s files and build them.
 2016-09-17 23:55:55 -04:00
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 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 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.
