* module/system/vm/traps.scm (trap-at-procedure-ip-in-range): Rework not
to call the handler when returning to a frame that was already
entered. So now breaking at foo.scm:1234 doesn't break when returning
to that line.
* module/srfi/srfi-45.scm: New file, containing the reference implementation of
SRFI 45, slightly adapted to use SRFI-9.
* module/Makefile.am (SRFI_SOURCES): Added srfi/srfi-45.scm.

* test-suite/Makefile.am (SCM_TESTS): Add tests/srfi-45.test.
* doc/ref/srfi-modules.texi (SRFI-45): New node and subsection;
essentially a shortended transcript of the SRFI-45 specification.
* module/srfi/srfi-42/ec.scm: New file; reference implementation of
SRFI 42.
* module/srfi/srfi-42.scm: New file; module for SRFI 42.
* module/Makefile.am (SRFI_SOURCES): Add srfi/srfi-42.scm.
(NOCOMP_SOURCES): Add srfi/srfi-42/ec.scm.
* test-suite/tests/srfi-42.test: New file; test suite for SRFI 42.
* test-suite/Makefile.am: SCM_TESTS: Add tests/srfi-42.test.
* module/system/vm/traps.scm (trap-in-procedure): If we are
(re-)entering the procedure from a return, call the enter-proc with
the returnee, not the returner.
(in-range?): Tighten up a bit.
(program-sources-before-retire): New helper, like program-sources but
indexed before instructions are retired instead of after.
(program-sources-by-line): Use program-sources-before-retire so that
we can break on instructions by source line *before* those
instructions are executed.
As module/oop/goops/stklos.scm, the available compatibility is
superficial only, so it isn't worth documenting.
* doc/ref/goops.texi (STKlos Compatibility): Removed.
* doc/ref/goops.texi (Defining New Classes): Move `Class Definition
Internals' and `Customizing Class Definition' notes to the
metaobject protocol section.
* module/system/vm/trap-state.scm (add-trap-at-source-location!):
* module/system/vm/traps.scm (trap-at-source-location): Rename "line"
argument to "user-line", indicating that the line is one-based instead
of zero-based. Decrement the line before handing off to
source-closures-or-procedures and source->ip-range.
* module/system/vm/program.scm (source:line-for-user): New exported
procedure, returns a 1-indexed line, suitable for presentation to a
user.
(write-program): Use source:line-for-user when making fallback names.
* module/system/vm/coverage.scm (coverage-data->lcov):
* module/language/assembly/disassemble.scm (source->string):
* module/system/repl/debug.scm (print-frame): Use source:line-for-user.
* libguile/stackchk.h: Include private-options.h if we are building
guile.
* libguile/vm.c (scm_c_vm_run): Check for C stack overflow before
entering the engine.
Fixes an error when running ./configure:
./configure: line 31873: text: command not found
* configure.ac: Change "text" to "test", in libltdl-related code.
* libguile/eval.c:
* libguile/debug.c (scm_debug_opts): Move here, from eval.c. Change
SCM_BACKTRACE_P to 1, initially.
* libguile/private-options.h: Make all options vars private.
* doc/ref/api-debug.texi (Programmatic Error Handling): Rename from
"Debug on Error". Reorganize subsections according to when the error
is handled.
* doc/ref/api-options.texi: Adapt xref.
* doc/ref/api-debug.texi (Debug on Error): Move debug options here (for
now). Leave debug-options-interface undocumented.

to the sections where the options documentation is now. Update the
options example transcript.
* doc/ref/api-options.texi (Debugger options):
* doc/ref/repl-modules.texi (Readline Options): Use 'help instead of
'full (they are entirely equivalent right now). Update output to show
options in the right order.
* doc/ref/api-evaluation.texi (Scheme Read): Fold all reader options
docs into this section. Undocument read-options-interface.
(Scheme Write): New section for `write' and `display', and the print
options. print-enable/print-disable are not documented, as there are
no boolean print options. print-options-interface is likewise
undocumented.
* doc/ref/api-options.texi: Remove discussion of options in
general. Move read options to Scheme Read, and print options to Scheme
Write.
* doc/ref/api-io.texi (Reading): Link to Scheme Read.
(Writing): Move write and display to Scheme Write, and link there.
* doc/ref/srfi-modules.texi:
* doc/ref/api-debug.texi:
* doc/ref/api-data.texi: Update xrefs.
* libguile/private-options.h (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P):
* libguile/read.c (scm_read_opts): Remove unused elisp-vectors option,
and the elisp-strings option (which allowed \( and \) escapes in
strings).
(scm_read_string): Remove the elisp-strings case.
* doc/ref/api-options.texi (Reader options): Update, and update wording
of the case-insensitive bit.
* libguile/frames.h:
* libguile/frames.c (scm_frame_stack_pointer): New function.
* module/system/repl/debug.scm (print-registers): New function, prints
out registers.
* module/system/repl/command.scm (registers): New debugging
meta-command.
(inspect): Not a stack-command, a normal meta-command.
* libguile/script.c (scm_compile_shell_switches): Select the debugging
VM in the cases that we previously would select deval -- when running
interactively without --no-debug, or otherwise with --debug.
* libguile/vm.c: Default to the regular engine.
(scm_c_set_vm_engine_x): Remove requirement for the VM to have no
pending computations.
Patch accepted upstream:
<http://lists.gnu.org/archive/html/guile-devel/2010-09/threads.html#00114>.
* module/ice-9/match.upstream.scm (match-two): Add support for `..1'.
* test-suite/tests/match.test ("matches")["list ..1", "list ..1, with
predicate"]: New tests.
("doesn't match")["list ..1", "list ..1, with predicate"]: New tests.
* module/srfi/srfi-27.scm: New file; implementation of SRFI 27 in terms
of the existing random number generator.
* module/Makefile.am (SRFI_SOURCES): Add srfi/srfi-27.scm.
* test-suite/tests/srfi-27.test: New file; minimal test suite for SRFI 27.
* test-suite/Makefile.am (SCM_TESTS): Add tests/srfi-27.test.
* doc/ref/srfi-modules.texi: Add subsection on SRFI-27 based
on the specification.
* libguile/vm.h (scm_c_vm_run): Make internal.
* libguile/vm.c (vm_default_engine): New static global variable.
(make_vm): Set vp->engine based on
(scm_vm_apply): Remove in favor of call-with-vm.
(scm_thread_vm, scm_set_thread_vm_x): Remove these, as they did not
have a well-defined meaning, and were dangerous to call on other
threads.
(scm_the_vm): Reinstate previous definition.
(symbol_to_vm_engine, vm_engine_to_symbol)
(vm_has_pending_computation): New helpers.
(scm_vm_engine, scm_set_vm_engine_x, scm_c_set_vm_engine_x): New
accessors for VM engines.
(scm_c_set_default_vm_engine_x, scm_set_default_vm_engine_x): New
setters for the default VM engine.
(scm_call_with_vm): New function, applies a procedure to arguments in
a context in which a given VM is current.
* libguile/eval.c (eval, scm_apply): VM dispatch goes through
scm_call_with_vm.
* test-suite/tests/control.test ("the-vm"):
* module/system/vm/coverage.scm (with-code-coverage): Use call-with-vm.
* module/system/vm/vm.scm: Update exports.
* test-suite/vm/run-vm-tests.scm (run-vm-program):
* test-suite/tests/compiler.test ("current-reader"): Just rely on the
result of make-program being an applicable.
* test-suite/tests/eval.test ("stack overflow"): Add a note that this
test does not test what it should.
The `mpz_t' associated with a bignum would never be freed, so an
expression like `(while #t (expt 2 5000))' would quickly lead to memory
exhaustion.
* libguile/numbers.c (finalize_bignum): New function.
(make_bignum): Register it as a finalizer for P.
* libguile/numbers.c (make_bignum): New function.
(scm_i_mkbig, scm_i_long2big, scm_i_ulong2big, scm_i_clonebig,
scm_i_dbl2big, scm_i_mpz2num): Use it.
* libguile/_scm.h (scm_aligned_cell, scm_t_aligned_cell): Remove. The
whole approach was misguided as the compiler can't guarantee absolute
alignment on the stack.
* libguile/vm.c (vm_dispatch_hook): Take care of FRAME's alignment
explicitly so that it's correct even if the current stack frame isn't
8-byte aligned (as can be the case on i686--the SysV i386 ABI just
says that the stack is word-aligned.)
The characters U+0007 to U+000D have non-hex forms for their
escapes when in written strings.
* libguile/print.c (write_character): use non-hex escapes
* test-suite/tests/reader.test (write R6RS string escapes): adjust test
* doc/ref/goops.texi (Defining New Classes): Remove "fixme" text
(saying we should have something that we in fact already have). A
few minor edits throughout.
(Basic Class Definition): Move content up into `Defining New
Classes'.
(Class Options): Move after `Slot Options' (because slot options are
more important). Remove doc of the #:environment option, since I
believe it's now fictitious.
(Slot Options): Reorder the options so that the most commonly used
ones come first.
* doc/ref/goops.texi (Metaobjects and the Metaobject Protocol): Remove
para about GOOPS classes belonging to the usual Scheme namespace.
Interest doesn't justify the space that it takes.
