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.

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.

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.

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.

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.

88fb231d6e Better constraint syntax; mcgg now passes register usage information up to mcg;

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

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.

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).

21898f784a We're going to need some type inference after all, I think. Let's do a little

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.

0d246c0d73 Much better handling of fragments (no run-time code needed to distinguish them

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).

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.

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.

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.

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.

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

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.

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

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.

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.
