* module/language/cps/intset.scm (intset-add!): If the root is a
branch but isn't editable, be sure to actually update the transient
intset's root to store the writable root.
The tentative plan is to replace CPS with CPS2, and to rename CPS2 to
CPS. We will add a pass to compile tree-il to CPS2, then work from
the top down to replace the CPS compiler passes.
* module/language/cps2.scm:
* module/language/cps2/compile-cps.scm:
* module/language/cps2/renumber.scm:
* module/language/cps2/utils.scm: New files.
* module/Makefile.am: Add new files to build.
* module/language/cps/intmap.scm (intmap->alist, print-intmap)
(print-transient-intmap): New functions.
Install the new functions as printers for <intmap> and <transient-intmap>.
* module/language/cps/intset.scm (make-atomic-reference)
(get-atomic-reference, set-atomic-reference!): New functions.
(*branch-size-with-edit*, *edit-index*): New constants.
(<transient-intset>): New data type.
(new-branch, clone-branch-and-set): Adapt to set edit field.
(transient-intset, persistent-intset): New exports.
(intset-add!): New interface, supporting "transient" intsets.
(intset-ref, intset-next, intset-prev, intset-fold, intset-fold2):
Work with transients.
* module/language/cps/intmap.scm (make-atomic-reference):
(get-atomic-reference, set-atomic-reference!): New helpers.
(*branch-size-with-edit*, *edit-index*): Branches now have a trailing
field, an atomic reference to their owner.
(<transient-intmap>): New record type. A mutable intmap.
(new-branch): Set the "edit" field on the branch.
(clone-branch-and-set): No editor for this field.
(assert-readable!, writable-branch): New helpers.
(transient-intmap, persistent-intmap): New exported functions.
(intmap-add!): New function.
(intmap-next, intmap-prev, intmap-ref): Work on transient intmaps.
(intmap-fold): Persist the intmap before folding over it.
* module/language/cps/intmap.scm (*branch-bits*): Switch to 32-way
branching. Marginally faster on lookup, and creation costs can be
amortized via using the transient interface. Marginal speedup for
assembler.scm compilation.
* module/language/cps/intmap.scm (meet-error): New helper.
(intmap-add, intmap-union, intmap-intersect): The "meet" argument is
optional and defaults to meet-error.
* module/language/cps.scm ($rec): Replace $letrec with $rec, which is an
expression, not a term. This means that the names bound by the letrec
appear twice: once in the $rec term, and once in the continuation.
This is not very elegant, but the situation is better than it was
before. Adapt all callers.
* doc/ref/compiler.texi (CPS in Guile): Incomplete documentation
updates. I'll update these later when the IL settles down.
* module/ice-9/eval.scm (primitive-eval): Factor out primitive=?
helper. Simplify compile-top-call. Add compile-top-branch for
primcall branches, so the compiler can see the specialized branch
operator.
* module/ice-9/eval.scm (primitive-eval): Lazily compile lambda bodies.
Special-case calls to top-level or module variables, and recognize
some of those calls as primcalls. In that case, emit closures with
the primcalls.
* module/language/cps/compile-bytecode.scm (optimize, compile-bytecode):
Marginally improve bootstrap memory usage by not retaining stale
copies of already-rewritten terms.
* libguile/libguile-2.2-gdb.scm (vm-frame-function-name): Don't default
to the address, as we will have better identifying info via the file
name.
(vm-frame-source): New helper.
(compile-time-cond): For some reason "else" matching wasn't working;
punt and use expressions.
(snarfy-frame-decorator): Rename from decorator, and adapt to new
version of Guile frame filter patch.
(vm-frame-filter): Adapt to frame filter changes, and fill in source
info.
* libguile/arrays.c (scm_i_print_array): Print the dimension whenever
the array is a true scm_tc7_array.
* test-suite/tests/arrays.test: Check that non-vector 1D arrays print as
expected.
* libguile/libguile-2.2-gdb.scm (make-scm-pretty-printer-worker):
(%scm-pretty-printer): Refactor to avoid printing all struct / array
fields by hinting these as arrays. The resulting print is not as
faithful to the original data, but that's probably OK.
These features depend on a patch to GDB that has not been merged yet.
If GDB doesn't support the annotator/filter interface, the code have no
effect.
* libguile/libguile-2.2-gdb.scm (compile-time-cond): New helper.
(snarfy-frame-annotator): Simple annotator that gives subr names for
snarfed gsubrs.
(vm-frame-filter): New filter that interleaves Scheme frames with C
frames on the stack when the user asks for a backtrace.
* libguile/libguile-2.2-gdb.scm: Update to work with Guile 2.2 stacks.
Represent the VM stack as a SRFI-41 stream, which will work better
with the frame filter interface. Add support for getting the vm
frame's function name, if possible.
* module/ice-9/psyntax.scm (resolve-identifier): There is a case where a
syntax object can resolve to itself. Prevent an infinite loop in that
case by continuing to resolve by name.
* module/ice-9/psyntax-pp.scm: Regenerate.
* test-suite/tests/syncase.test ("infinite loop bug"): Add a test.
* libguile/goops.h (SCM_VTABLE_FLAG_GOOPS_STATIC): Reserve the fourth
GOOPS flag to indicate that a class has static slot allocation.
* libguile/goops.c (scm_init_goops_builtins): Define
vtable-flag-goops-static for goops.scm.
* module/oop/goops.scm (class-has-statically-allocated-slots?): New
helper.
(build-slots-list): Instead of the ad-hoc checks for <class> or
<slot>, use the new helper.
(initialize): Accept #:static-slot-allocation? keyword.
* module/system/foreign-object.scm (make-foreign-object-type): Declare
foreign object classes as having static slot allocation.
* test-suite/tests/goops.test ("static slot allocation"): Add tests.
* libguile/goops.c (is_accessor_method, scm_compute_applicable_methods):
Fix regression from 51f66c9120 (2009).
Accessor methods are added on each subclass on which the slot is
present; therefore if a subclass doesn't have a method, then the
methods doesn't apply. Truly fixes#17355, unlike
583a23bf10.
* module/oop/goops.scm (compute-cmethod, compute-getter-method)
(compute-setter-method): Revert earlier changes.
* test-suite/tests/goops.test ("accessor slots"): Update for new
expectations, in agreement with Guile 1.8.
* module/oop/goops/compile.scm: Inline into goops.scm, leaving a
compatible interface stub behind.
* module/oop/goops/dispatch.scm: Don't import (oop goops compile), to
break circularities.
* module/oop/goops.scm: Move (oop goops util) include up to the top, and
import (ice-9 match).
(compute-cmethod): Move here from compile.scm. Add a special case for
accessor methods, so as to fix bug #17355.
(compute-getter-method, compute-setter-method): #:procedure slot is
now generic.
* test-suite/tests/goops.test ("accessor slots"): New test.
