* module/Makefile.am: Add language/sassy.scm. Probably EXTRA_DIST the
dependant files, too.
* module/language/sassy.scm: New file, the sassy loader. Sassy is
originally R5RS code that loads a number of files. I've converted that
toplevel file to be a Guile module that *includes* the subfiles, so
that it all gets compiled together. It's a pretty bad hack though,
because what I should be doing is including them relative to the
sassy.scm source location, but we don't know that at expansion time.
Something to fix.
really bad hack in it so that it will compile correctly -- p
* module/language/sassy/: All the sassy files and some changelog
information. All of these files are LGPLv2.1+, so they can be included
in Guile.
* test-suite/standalone/sassy/tests/: Add the sassy unit tests.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-sassy: Hook the sassy unit tests up to our
test suite.

* test-suite/tests/compiler.test ("psyntax")["redefinition", "compile in
current module", "compile in fresh module"]: Use `begin' to enforce
evaluation order. Thanks Andy!
|
|
* module/ice-9/boot-9.scm (module-name): When making MOD non-anonymous,
bind it in the `(%app modules)' name space.
* test-suite/tests/compiler.test ("psyntax")["compile in current
module", "compile in fresh module"]: New tests.
* test-suite/tests/modules.test ("foundations")["modules don't remain
anonymous"]: New test.
|
|
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (chi-top)[define-form]: If a same-named
imported variable exists, take its value instead of `#f'.
* test-suite/tests/compiler.test ("psyntax")["redefinition"]: New tests.
|
|
* doc/ref/compiler.texi:
* doc/ref/vm.texi: Update for recent changes.
* module/language/assembly/disassemble.scm (disassemble-load-program):
Don't print nops, they are distracting.
|
|
* module/language/tree-il/compile-glil.scm (compile-glil): Compute
warnings before optimizing, as unreferenced variables will be
optimized out.
* libguile/_scm.h: Fix C99 comment.
* module/language/tree-il/fix-letrec.scm (partition-vars): Also analyze
let-bound vars.
(fix-letrec!): Fix a bug whereby a set! to an unreffed var would be
called for value, not effect. Also "fix" <let>-bound lambda
expressions -- really speeds up pmatch.
* test-suite/tests/tree-il.test ("lexical sets", "the or hack"): Update
to take into account the new optimizations.

This requres the creation of a new type
scm_t_string_failed_conversion_handler to replace libunistring's
enum iconveh_ilseq_handler.

make-keyword and make-symbol as appropriate.
* module/language/tree-il/compile-glil.scm (flatten): When compiling a
ref to a primitive (not a call), first see if the primitive is

fallback path.
|
|
* libguile/_scm.h (SCM_OBJCODE_COOKIE): Move the objcode cookie define
here, so that load.c can use it. This is a private header.
* libguile/load.c (FALLBACK_DIR): Include the objcode cookie in the
fallback path. Should fix problems when objcode changes incompatibly
during the 1.9 series.
* libguile/objcodes.c: Adapt to SCM_OBJCODE_COOKIE move.
This should fix http://article.gmane.org/gmane.lisp.guile.devel/9059.

%string-dump and %symbol-dump are modified to return assocation lists
of string and symbol attributes instead of printing to stderr. They
are no longer conditional on SCM_DEBUG.

This adds full Unicode strings as a datatype, and it adds some
minimal functionality. The terminal and port encoding is assumed
to be ISO-8859-1. Non-ISO-8859-1 characters are written or
input as string character escapes.
The string character escapes now have 3 forms: \xXX \uXXXX and
\UXXXXXX, for unprintable characters that have 2, 4 or 6 hex digits.
The process for writing to strings has been modified. There is now a
function scm_i_string_start_writing that does the copy-on-write
conversion if necessary.
To compile strings that may be wide, the VM storage of strings and
string-likes has changed.
Most string-using functions have not yet been updated and may break
when used with wide strings.

|
* module/language/tree-il/analyze.scm (analyze-lexicals): Rework to
actually determine when a fixed-point procedure may be allocated as a
label.
* module/language/tree-il/compile-glil.scm (emit-bindings): Always emit
a <glil-bind>. Otherwise it's too hard to pair with unbindings.
(flatten-lambda): Consequently, here we only `bind' if there are any
vars to bind. This doesn't make any difference, given that lambdas
don't have trailing unbind instructions, but it does keep the GLIL
output the same for thunks -- no extraneous (bind) instructions. Keeps
tree-il.test happy.
(flatten): Some bugfixes. Yaaay, it works!!!
|
|
* module/language/tree-il/compile-glil.scm (flatten-lambda, flatten):
Implement compilation of label-allocated lambda expressions. Quite
tricky, we'll see if this works when the new analyzer lands.
|
|
* module/language/tree-il/analyze.scm: Add some more comments about
something that will land in a future commit: compiling fixpoint
lambdas as labels.
(analyze-lexicals): Reorder a bit, and add a label alist to procedure
allocations. Empty for now.
* module/language/tree-il/compile-glil.scm (flatten): Adapt to the free
variables being in the cddr of the allocation, not the cdr.
|
|
* libguile/vm-i-scheme.c (vector-ref, vector-set): Sync registers if we
call out to C.
* module/language/tree-il/compile-glil.scm (flatten-lambda): Add an
extra argument, the self-label, which should be the gensym under which
the procedure is bound in a <fix> expression.
(flatten): If we see a call to a lexical ref to the self-label in a
tail position, rename and goto instead of goto/args, which will tear
down the frame -- or will, in the future. It's a primitive form of
loop detection.
* module/language/tree-il/primitives.scm (zero?): Expand to (= x 0).
|
|
* module/Makefile.am (SOURCES): Reorganize so GHIL is compiled last,
along with ecmascript.
* module/language/scheme/spec.scm: Remove references to GHIL, as it's
bitrotten and obsolete..
* module/language/tree-il.scm (make-tree-il-folder): Rework so that we
only have down and up procs, and call down and up on each element.
* module/language/tree-il/analyze.scm (analyze-lexicals): Fix a thinko
handling let-values.
* module/language/tree-il/fix-letrec.scm: Actually implement fixing
letrec. The resulting code will perform better, but violations of the
letrec restriction are not detected. This behavior is allowed by the
spec, but it is undesirable. Perhaps that will be fixed later.
* module/language/tree-il/inline.scm (inline!): Fix a case in which
((lambda args foo)) would be erroneously inlined to foo. Remove empty
let, letrec, and fix statements.
* module/language/tree-il/primitives.scm (effect-free-primitive?): New
public predicate.
|
|
* module/srfi/srfi-11.scm (let-values): In the one-clause case, avoid
going through temporary variables.
* module/language/tree-il/inline.scm (inline!): Add another case:
(call-with-values (lambda () ...) (lambda ... ...) -> let-values.
* module/language/tree-il/compile-glil.scm (flatten): Fix a bug
compiling applications in "vals" context.
* module/language/tree-il/analyze.scm (analyze-lexicals): Fix a couple
bugs with let-values and rest arguments.
|
|
* module/language/tree-il.scm (tree-il-fold): Fix for let-values case.
(make-tree-il-folder): New public macro, makes a multi-valued folder
specific to the number of seeds that the user wants.
* module/language/tree-il/optimize.scm (optimize!): Reverse the order of
inline! and fix-letrec!, as the latter might expose opportunities for
the former.
* module/srfi/srfi-11.scm (let-values): Reimplement in terms of
syntax-case, so that its expressions may reference hygienically bound
variables. See the NEWS for the rationale.
(let*-values): An empty let*-values still introduces a local `let'
binding contour.
* module/system/base/syntax.scm (record-case): Yukkkk. Reimplement in
terms of syntax-case. Ug-ly, but see the NEWS again: "Lexical bindings
introduced by hygienic macros may not be referenced by nonhygienic
macros."
|
|
* libguile/vm-i-system.c (fix-closure): New instruction, for wiring
together fixpoint procedures.
* module/Makefile.am (TREE_IL_LANG_SOURCES): Add fix-letrec.scm.
* module/language/glil/compile-assembly.scm (glil->assembly): Reindent
the <glil-lexical> case, and handle 'fix for locally-bound vars.
* module/language/tree-il.scm (<fix>): Add the <fix> tree-il type and
accessors, for fixed-point bindings. This IL construct is taken from
the Waddell paper.
(parse-tree-il, unparse-tree-il, tree-il->scheme, tree-il-fold)
(pre-order!, post-order!): Update for <fix>.
* module/language/tree-il/analyze.scm (analyze-lexicals): Update for
<fix>. The difference here is that the bindings may not be assigned,
and are not marked as such. They are not boxed.
(report-unused-variables): Update for <fix>.
* module/language/tree-il/compile-glil.scm (flatten): Compile <fix> to
GLIL.
* module/language/tree-il/fix-letrec.scm: A stub implementation of
fixing letrec -- will flesh out in a separate commit.
* module/language/tree-il/inline.scm: Fix license, it was mistakenly
added with LGPL v2.1+.
* module/language/tree-il/optimize.scm (optimize!): Run the fix-letrec!
pass.
|
|
* module/Makefile.am (TREE_IL_LANG_SOURCES):
* module/language/tree-il/inline.scm: Add a brain-dead inliner, to
inline ((lambda () x)) => x.
* module/language/tree-il/optimize.scm (optimize!): Invoke the inliner.
|
|
* libguile/vm-i-scheme.c: Add add1 and sub1 instructions.
* module/language/tree-il/compile-glil.scm: Compile 1+ and 1- to add1
and sub1.
* module/language/tree-il/primitives.scm (define-primitive-expander):
Add support for `if' statements in the consequent.
(+, -): Compile (- x 1), (+ x 1), and (+ 1 x) to 1- or 1+ as
appropriate.
(1-): Remove this one. Seems we forgot 1+ before, but we weren't
compiling it nicely anyway.
* test-suite/tests/tree-il.test ("void"): Fix expected compilation of (+
(void) 1) to allow for add1.
|
|
* configure.ac: Rework gmp and unistring checks to use
AC_LIB_HAVE_LINKFLAGS, so that the compilation checks run with the
right -L/-l flags.
* libguile/Makefile.am (libguile_la_LIBADD): Adapt to need to add
$(LIBGMP) and $(LIBUNISTRING) here.
Hopefully this solves
http://article.gmane.org/gmane.lisp.guile.bugs/4288.
|
|
* configure.ac:
* guile-readline/configure.ac: Rename from configure.in, as recommended
by the autoconf manual.
|
|
* libguile/numbers.c (mem2decimal_from_point, mem2ureal, mem2complex):
Fix a number of cases where, for invalid numbers, we could read past
the end of the buffer. This happened in e.g. "1.0+", "1/" and "1.0f".
But I couldn't figure out how to test for these, given that the
behavior depended on the contents of uninitialized memory in the
reader buffer. We'll just have to be happy with this.
Thanks to Kjetil S. Matheussen for the report.
