* libguile/r6rs-ports.c (cbp_mark): A closed port will have had its
stream destroyed, so don't dereference the stream in that case. Patch by
Mike Gran.
* module/ice-9/psyntax.scm (source-wrap): Use decorate-source, for
clarity.
(syntax-type): When turning the RHS of (define (foo) ...) into a
lambda, decorate the resulting lambda expression with source
information, as the RHS later goes to chi-expr, which receives no
source information. Perhaps that is a bug. In any case, fixes some
source location lossage, reported by Jao.
* module/ice-9/psyntax-pp.scm: Regenerated.
* libguile/filesys.h:
* libguile/filesys.c (scm_canonicalize_path): New function,
canonicalize-path.
* module/system/base/compile.scm (compiled-file-name): Canonicalize the
filename so that compiling e.g. ../foo.scm doesn't compile to
~/.guile-ccache/1.9/../foo.scm.
* Makefile.am: Add rule to make a ChangeLog at dist-time. The rule comes
from coreutils.
* build-aux/gitlog-to-changelog: New helper script, from gnulib.
This allows, e.g., ",c #u8(1 2 3)" at the REPL to actually work instead
of failing to decode `load-array'.
* module/language/assembly/decompile-bytecode.scm (decode-bytecode):
Account for the `load-array' instruction, which is followed by a
bytevector instead of a string. We should find a more elegant way to
do that.
* libguile/read.c (scm_read_bytevector): New function.
(scm_read_sharp): Add `v' case for bytevectors.
* test-suite/lib.scm (exception:read-error): New variable.
* test-suite/tests/bytevectors.test ("Datum Syntax"): New test set.
* libguile/bytevectors.c (bytevector_equal_p): New function.
* test-suite/tests/bytevectors.test ("2.3 Operations on Bytes and
Octets")["equal?"]: New test.
* NEWS: Update, but only partially. I wanted to push out this
incomplete, not yet organized draft for review, if anyone had
comments. I'll pick it up tomorrow morning.
* THANKS: Add Juhani, whose last name changed?
This patch uses the AC_LIB_LINKFLAGS macro, provided by Gnulib's
havelib module, to provide --with-gmp-prefix and
--with-readline-prefix configure options. Many thanks to Bruno Haible
for suggesting and explaining this to me.
* configure.in (top level): Add AC_LIB_LINKFLAGS(gmp).
* guile-readline/configure.in (AC_CONFIG_AUX_DIR): Change to
../build-aux, to share the main build-aux directory and so avoid
having to distribute multiple copies of config.rpath.
(top level): Add AC_LIB_LINKFLAGS(readline).
* lib/Makefile.am, m4/gnulib-cache.m4: Regenerated by gnulib-tool for
new import of the `havelib' module.
* module/ice-9/boot-9.scm (define-private): Remove apocyphal comment. The
FIXME would really be to remove `define-private', though...
* module/ice-9/optargs.scm (defmacro*, defmacro*-public): Fix these
macros. Thanks to Dale Smith for the report.
* libguile/eval.c (scm_debug_opts): Up the default stack limit by a
factor of 4. Psyntax expansions currently bounce back and forth between
the VM and the interpreter, due to `map'. (Hopefully that won't be the
case in the future, when have map in scheme, and we get an inliner.)
Anyway when expanding a big nested expression, as for example in
(language ecmascript compile-ghil) -- the pmatch code ends up being
super-nested -- we can consume loads o stack.
So given that on desktop machines, where rlimit is likely to be unset,
default rlimits are around 8 or 10 MB or so, let's bump up our default
limit to 640KB (on 32-bit). Should be enough for anyone.
See http://thread.gmane.org/gmane.lisp.guile.devel/8599/focus=8662 for
more info. Thanks to Mark H. Weaver for the diagnosis!
* module/ice-9/boot-9.scm (define-option-interface): Fix (debug-options
'full), along with other options. Thanks to Mark Weaver for the tip.
* THANKS: Update, though many more names need to be added.
* module/language/ecmascript/compile-ghil.scm (comp): Just use pmatch,
not ormatch. Now with syncase running over everything, it doesn't
matter.
* module/ice-9/boot-9.scm (false-if-exception): Avoid saving stacks
inside false-if-exception. There's probably a more general solution to
this, though. Fixes getting bogus backtraces sometimes.
* module/Makefile.am (ECMASCRIPT_LANG_SOURCES): Reorder things so that
spec comes last.
* module/language/elisp/README: New file containing some notes.
* module/language/elisp/compile-tree-il.scm: New file with compilation code.
* module/language/elisp/spec.scm: Updated language definition.
* module/ice-9/compile-psyntax.scm: Pretty-print psyntax-pp.scm, given
that we are going to compile it anyway.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/Makefile.am (ice-9/psyntax-pp.scm): Don't try autocompiling when
making psyntax-pp.scm.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (chi-top): Only affect the compile-time
environment if modules have booted.
* module/language/tree-il.scm: Rename let-exp and letrec-exp to let-body
and letrec-body. Add <let-values>, a one-expression let-values that
should avoid the needless creation of two closures in many common
multiple-value cases. We'll need to add an optimization pass to the
compiler to produce this form, though, as well as rewriting lambdas
into lets, etc.
I added this form instead of adding more special cases to the
call-with-values compile code because it's a useful intermediate form
-- it will allow the optimizer to perform constant folding across more
code.
* module/language/tree-il.scm (parse-tree-il, unparse-tree-il)
(tree-il->scheme, post-order!, pre-order!): Adapt to let/letrec body
renaming, and let-values.
* module/language/tree-il/analyze.scm (analyze-lexicals): Adapt for
renaming, and add cases for let-values.
* module/language/tree-il/compile-glil.scm (flatten): Add a new context,
`vals', used by let-values code for the values producer. Code that
produces multiple values can then jump to the let-values MV return
address directly, instead of trampolining into a procedure. Add code to
compile let-values.
* libguile/vm-i-scheme.c (FUNC2): Use a signed value for the intermediate
result here. Not sure what the effect is, though.
* module/ice-9/psyntax.scm (chi-top): Toplevel definitions ensure that
variables are defined in the current module. Fixes the specific case of
guile-lib's md5.scm, which redefines + -- this code is needed so that
we don't incorrectly open-code +.
* module/language/tree-il/primitives.scm (resolve-primitives!): I think
there were some cases in which vars and names would not resolve
properly here. Fix those.
* doc/ref/vm.texi (Loading Instructions): Remove references to
load-integer and load-unsigned-integer -- they're still in the VM but
will be removed at some point.
(Data Control Instructions): Add make-int64 and make-uint64.
* libguile/vm-i-loader.c (load-unsigned-integer): Allow 8-byte values.
But this instruction is on its way out, yo.
* libguile/vm-i-system.c (make-int64, make-uint64): New instructions.
* module/language/assembly.scm (object->assembly): Write out make-int64
and make-uint64 instructions, using bytevectors to do the endianness
conversion.
(assembly->object): And pretty-print them back, for disassembly.
* module/language/glil/compile-assembly.scm: Don't generate load-integer
/ load-unsigned-integer instructions.
Thanks to Greg Troxel for reporting, and Barry Fishman for the
explanation and fix.
* test-suite/tests/popen.test ("open-input-pipe"): Use shell function
`read' with an explicit argument, as apparently not all shells
support read with no argument.
* module/ice-9/psyntax.scm (syntax-type): Remove `external-macro', not
used any more. Take an extra arg, `for-car?', indicating that we're
checking on the type of a form in the car position. In the case that
the expression is a pair, do a full recursion on the car, which allows
us to catch the fact that the car of the following form is a macro:
((@ (ice-9 optargs) let-optional) ...)
and thus the form itself should be macroexpanded.
But, since we want to distingush `lambda' from `(lambda ...)', just as
we have global and global-call, we have core to the new `core-form'.
(chi-top, chi, chi-expr, chi-body, set!): Adapt to changes to
syntax-type.
* module/rnrs/bytevector.scm (rnrs):
* libguile/bytevectors.h:
* libguile/bytevectors.c (scm_uniform_array_to_bytevector): New function.
* libguile/unif.h:
* libguile/unif.c (scm_from_contiguous_typed_array): New function.
* libguile/vm-i-loader.c (load-array): New instruction, for loading byte
data into uniform vectors. Currently it copies out the data, though in
the future we could avoid that.
* module/language/assembly.scm (align-code): New exported function,
aligns code on some boundary.
(align-program): Use align-code.
* module/language/assembly/compile-bytecode.scm (write-bytecode): Support
the load-array instruction.
* module/language/glil/compile-assembly.scm (dump-object): Dump uniform
arrays. Neat :)
* libguile/vm-i-system.c (long-object-ref, long-toplevel-ref)
(long-toplevel-set): Add new instructions, for accessing the object
table with a 16-bit offset. HTMLprag defines a test program that has
more than 256 constants, necessitating this addition.
* doc/ref/vm.texi: Mention the new instructions.
* module/language/glil/compile-assembly.scm: Emit long refs for object
tables bigger than 256 entries.
