0.8.18.24.alpha64-3.11:
"You're just practice."

Test-motivated-fixes:
* Add lifetime constraints on some bignum vops so the register
allocator doesn't overwrite the arguments;
* Tweak error-code finding code in alpha-arch.c; make cosmetic
32->64-bit changes while we're at it (did this ever work?
It doesn't look like it could have.).

Tests now pass up to float.pure.lisp.

Add :CIX-guarded VOPs for integer-length, just for kicks.

0.8.18.25.alpha64-3.10:
"It's been a while."

* src/code/debug-int.lisp: remove #!-alpha cruft and 32-bit-isms;
* src/compiler/alpha/insts.lisp: fix part of disassembler printing;
* src/assembly/alpha/arith.lisp: fix GENERIC-*;
* src/code/print.lisp: use "new" bignum printer so that other
people besides me could build this version and have it print
bignums properly;
* src/runtime/cheneygc.c: misc declaration fixes.

Current status: builds, dies in tests/arith.pure.lisp with a
bignum error (bignum multiply vops are probably not working
correctly, since reading bignums gives some curious results).

0.8.18.25.alpha64-3.9:
"Victory is mine."

(1+ most-positive-fixnum) => 1152921504606846976

Can build a few files in warm load, errors out somewhere in
the compiler, probably because float support still needs
a little work in some places (although I cannot find anyplace
where the compiler would be terribly concerned with the
quality of the floating-point code...does PCL use FP?).

* revert GC changes to correspond with jsnell's GC changes
for 64-bitness;
* src/runtime/print.h: remove lowtag_Names, as it is now
autogenerated by GENESIS;
* src/compiler/alpha/arith.lisp: fix thinko bug in ADD-WITH-CARRY
so that bignum operations work properly;
* src/compiler/alpha/float.lisp: fix some sign-extension issues,
since LDL already sign-extends the result;
* src/compiler/generic/vm-tran.lisp: port over COUNT fixes from
mainline.

0.8.18.25.alpha64-3.8:
"I only dog paddle."

* src/code/unix.lisp, src/runtime/wrap.c: change 'wrapped_stat'
structure in Lispland and C-land to use the proper types for
Tru64. This change will probably render SBCL unbuildable on
32-bit platforms unless 64-bit FFI types have been implemented
on said platform;
* src/runtime/alpha-assem.S: the offset saved by call_into_c must
be a fixnum (and is on other RISCy platforms because instructions
are 4 bytes and fixnums are 4-byte aligned--not so on the Alpha).
Make it so;
* src/code/{bit-bash,host-alieneval}.lisp: remove bogus alpha
conditionalization. This change fixes the "Unaligned access"
errors present on Tru64;
* src/compiler/alpha/{float,array}.lisp: modify float vops and
float array reffers for a 64-bit Lisp where N-WORD-BYTES != 4;
* src/compiler/alpha/parms.lisp: change storage classes for
64-bitness;
* src/compiler/alpha/insts.lisp: tweak instructions a bit, add
SEXTL instruction macro--which doesn't work and I'm not quite
sure why;
* src/compiler/macros.lisp: modify some array reffers to be
marginally more efficient (not enabled by default because
SEXT{B,W} are not necessarily implemented in hardware on all
Alpha implementations)

Build status: builds into cold-init, dies in
INTEGER-DECODE-DOUBLE-FLOAT, presumably due to the new float
vops accessing the wrong bits of DOUBLE-FLOATs. Said float vops
look right, though (they always do).

0.8.18.25.alpha64-3.7:
"The rest is trivial."

Minor changes:
* tools-for-build/ldso-stubs.lisp: untabify and update OSF/1
stub for a dynamically-linked world;
* src/runtime/alpha-assem.S: s/stl/stq/ (again, *sigh*)
* src/assembly/alpha/arith.lisp: optimize GENERIC-+/GENERIC--;
* src/compiler/generic/{interr,vm-type,vm-typetran}.lisp,
src/code/{pred,interr}.lisp: update with new 64-bit types and
add back specialized typechecks for {UN,}SIGNED-BYTE-32, on
the suspicion that they will be needed for the FFI.

Current status: plods forward until first GC (even with setting
up the pretty-printer, woohoo!), where it dies mysteriously
during scavenging. crhodes suggesting reverting the patches
made earlier to GC, as jsnell thoroughly 64-bitized the GC
for the x86-64 port; have to try that and see if that does
anything.

Various messages are blathered across the console about
unaligned accesses during setup of the pretty-printer; those
should be investigated...

"A day at the beach."

Small but important fixes:
* src/compiler/alpha/array.lisp: characters are 32 bits wide;
* src/compiler/alpha/call.lisp: fix LISTIFY-REST-ARGS VOP so that
the compiler will properly translate %LISTIFY-REST-ARGS;
* src/compiler/alpha/arith.lisp: invert MOVE argument order to
fix SIGNIFY-DIGIT.

0.8.18.25.alpha64-3.5:
"Try pushing that button there...No, how about that one?"

Commit 64-bit aware version of alpha-assem.S and perform several
minor cleanups on src/runtime/ files.

One can now start the built SBCL, but it errors out after
trying to USE-PACKAGE (hits undefined_tramp).

0.8.18.24.alpha64-3.4:
"Brick by brick, my friend. Brick by brick."

Various cleanups and a few more port-overs:
* src/compiler/generic/objdef.lisp: remove lots of the ugly
#!+alpha/#!-alpha nonsense; generalize some #!+x86-64 to
consider SB!VM:N-WORD-BITS instead;
* src/compiler/generic/genesis.lisp: some functional cleanups.
write out new file genesis/ldb-print.h so that LDB printing
stands half a chance of working sanely on 64-bit systems;
* src/compiler/alpha/array.lisp: use SB!C::RAW-VECTOR for
%RAW-{REF,SET}-FOO;
* src/compiler/alpha/arith.lisp: use FIXNUM-TAG-MASK where
appropriate;
* src/compiler/alpha/parms.lisp: add back
SB!KERNEL::UNDEFINED-ALIEN-ERROR;
* src/compiler/alpha/type-vops.lisp: remove unused variables;
* src/runtime/print.c: update to use genesis/ldb-print.h and
make a few other cleanups;
* src/runtime/interrupt.c: add back handle_guard_page_triggered;
* src/runtime/Config.alpha-osf1: compile 'sbcl' as a shared
executable (why was this ever disabled?) and enable building
of ldso-stubs.s;
* src/code/target-unithread.lisp: use SAP-REF-WORD when
appropriate.

Builds through make-host-2.sh; fails with 'Unable to obtain
requested swap space' error when executing the newly-built
sbcl, which I know I've seen before, but I don't remember
how I fixed it. :( (on OSF/1, anyway; Linux might do better?)

"That's impossible, even for a computer."

Forgotten fixes and adding back functionality:

take a STACK-ALLOCATED-P parameter;
* src/compiler/alpha/values.lisp: add %%POP-DX and %%NIP-DX;
* src/code/alpha-vm.lisp: instructions on Alpha are 4 bytes long,
not N-WORD-BYTES;
* src/code/cold-init.lisp: update debugging code to be 64-bit
aware;
* src/code/type-init.lisp: precompute 64-bit-friendly types.

0.8.18.25.alpha64-3.2:
"Ah, the bright promise of a disgusting new character!"

Various fixes revealed by make-host-1.sh:
* the backend deals in CHARACTER-{STACK,REG} rather than
BASE-CHAR-{STACK,REG}--change VOPs and VM definition;
* we have :UNSIGNED and :SIGNED modular arithmetic classes
now; make arith.lisp indicate the appropriate class;
* a few misspellings and thinkos in type-vops.lisp.

0.8.18.25.alpha64-3.1:
"Third time's the charm."

Commit an updated version of Christophe and Dan's work on
an Alpha64 port, motivated by Juho's recent work on AMD64.
I forward ported the alpha64_2 branch to 0.8.13.mumble,
and successfully reached the beginning of warm-init.
(1+ MOST-POSITIVE-FIXNUM) returns the right answer. :)

However, given that there has been a lot of work recently on
a 64-bit clean SBCL (and many improvements since 0.8.13.mumble),
doing another forward port seemed like a reasonable idea.
WARNING: I have not tried to build an actual alpha64 sbcl
with this version yet, but I can assure you that the build
did work properly for 0.8.13.x. I may have also forgotten
some files in src/code/ or thereabouts.

Improvements over the alpha64_2 branch:
* several arithmetic assembly VOPs have been rewritten;
* can compile simple DEFUNs;
* calling sequences updated to be closer to PPC.

Things which are known to not work:
* bignums (can't really tell, since printing of bignums is borked);
* unicode;
* linkage-tables;
* probably other things I am forgetting.

0.8.18.25:
Improvements to the statistical profiler.
* Add support for x86-64.
* Time spent in foreign functions was previously attributed to
"elsewhere". Now reported individually for all of them, and
"foreign function __open", "foreign function sin", etc.
* Walk the call stack to a depth of 8 instead of relying only
on the PC and RA from os-context-t (currently only on x86/x86-64).
Thus instead of just knowing that a lot of time is being spent
on (for example) bignum operations, we might find out where
the bignum operations are being initiated.
* Add a column for accrued time to the flat report.
* Add kludgy workaround for invalid frame-pointers in the
os-context-t structure causing segfaults.

Manual build fixes.

* Allow the manual to be built with an sbcl in a non-standard

build a manual without jumping through too many hoops.
* Add a docstring to sb-md5's md5sum-string, to make the
manual happy again.

0.8.18.14:
Merge x86-64-again branch onto HEAD.

Many, many, many 64-bit cleanups in code/, runtime/, compiler/,
compiler/generic/

New SAP-REF-WORD and friends.

Various fixes to the x86-64 backends (and addition of assembly/
and runtime/ files necessary). Implementation of Unicode-related
stuff by CSR. Signed modular arithmetic has not yet been
implemented.

A number of tests fail:
... alien.impure.lisp: enum <-> integer array conversion
... exhaust.impure.lisp: "deferred gubbins"
... float.pure.lisp: float infinities
... foreign.test.sh: "deferred gubbins"

It's possible that this merge will cause alpha32 to break in an
interesting way, probably related to undefined-alien. Needs
debugging. Other architectures have been tested, but of course
it's possible that something has gone wrong.

Though I (CSR) am merging this, the vast majority of the work was
done by Juho Snellman (building on Dan Barlow's initial work to
get it into executing lisp code in cold-init), with guest appearances
by Cheuksan Edward Wang and Vincent Arkesteijn.
