the counters are not initialized.

(make-cont-folder): New macro, generates an n-ary folder.
(compute-max-label-and-var): New function, uses make-cont-folder.

* module/language/cps/elide-values.scm:
* module/language/cps/reify-primitives.scm:
* module/language/cps/specialize-primcalls.scm: Use let-fresh instead of
let-gensyms, and wrap in a with-fresh-name-state as needed.
* module/language/tree-il/compile-cps.scm: Remove hack to avoid
importing let-gensyms from (language tree-il).

exact integers as labels.
(link-debug): Explicitly mark low-pc as being an "addr" value.
* test-suite/tests/signals.test: Update setitimer tests to sloppily
match both times -- it seems that the interval can also be sloppy on
some platforms, sadly.
* test-suite/standalone/test-out-of-memory (*limit*): Reduce limit to 50 MB.
Adapt vector test to avoid exceeding maximum vector size on 32-bit
systems.
* libguile/gc.c (scm_oom_fn, scm_init_gc): Install an out-of-memory
handler that raises an unwind-only out-of-memory exception.
(scm_gc_warn_proc, scm_init_gc): Install a warning proc that tries to
print to the current warning port, if the current warning port is a
file port.
(scm_gc_after_nonlocal_exit): New interface. Should be called after a
nonlocal return to potentially collect memory; otherwise allocations
could try to expand again when they should collect.
* libguile/continuations.c (scm_i_make_continuation):
* libguile/eval.c (eval):
* libguile/throw.c (catch):
* libguile/vm.c (scm_call_n): Call scm_gc_after_nonlocal_exit after

* libguile/init.c (scm_init_standard_ports): Init the current warning
port.
* module/ice-9/boot-9.scm: Remove definitions for current-warning-port.
Instead, steal it from the boot objtable with port-parameterize!.
This is a follow-up to e26ab06.
* libguile/print.c (scm_simple_format): Pass 1 to
SCM_VALIDATE_OPORT_VALUE, for 'destination'.
* test-suite/tests/format.test ("simple-format"): Add test.
Fixes <http://bugs.gnu.org/17044>.
Reported and diagnosed by Xin Wang <dram.wang@gmail.com>.
* module/rnrs/io/simple.scm (open-input-file, open-output-file): Pass
missing buffer-mode argument to open-file-{input,output}-port.
Previously, (native-transcoder) was incorrectly passed as the
buffer-mode argument, so no transcoder was provided, thus creating a
binary port.
* libguile/srfi-4.c (DEFINE_SRFI_4_C_FUNCS): Fix bad assumption that
width was a byte width. Thanks very much to Barry Fishman for the
report, and to Daniel Llorens for tracking it down.
* test-suite/standalone/Makefile.am (test_srfi_4_CFLAGS):
* test-suite/standalone/test-srfi-4.c: Add test.
* module/texinfo.scm (read-char-data): Preserve newlines in @example and
similar environments in the case when the next line starts with an @.
* test-suite/tests/texinfo.test ("test-texinfo->stexinfo"): Add a test.
* doc/ref/api-data.texi (Symbol Read Syntax): Mention the 'r7rs-symbols'
print option, and provide example code to enable both the read and
print options. Add 'r7rs-symbols' to the concept index.
* module/ice-9/boot-9.scm (for-each):
* module/srfi/srfi-1.scm (for-each): Re-implement one-list case using an
explicit check for list? instead of the tortoise-hare thing. Seems to
be faster!
* module/system/repl/error-handling.scm (call-with-error-handling): Add
#:report-keys kwarg, so that unwind-only exceptions (stack-overflow in
particular) get reported.
* doc/ref/api-debug.texi (Pre-Unwind Debugging): Add documentation for
#:report-keys kwarg of call-with-error-handling.
(Stack Overflow): New subsubsection.
(Debug Options): Remove discussion of stack overflow.
* libguile/throw.c (throw_without_pre_unwind): Newline after the
unwind-only warning.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-stack-overflow: New test to handle
mmap/malloc failure.
* doc/body.texi: Write detailed description and examples for
jit_get_memory_functions, jit_set_memory_functions,
jit_get_code, jit_set_code, jit_get_data and jit_set_data.
* include/lightning.h, include/lightning/jit_private.h,
lib/lightning.c: Implement the new jit_set_data() interface,
and the new jit_get_data() helper. Like jit_set_code(),
jit_realize() should be called before jit_set_data().
The most common usage should be jit_set_data(JIT_DISABLE_DATA
| JIT_DISABLE_NOTE), to force synthesize any float/double
constant in the stack and not generate any debug information.
* lib/jit_note.c: Minor change to debug note generation as
now it uses an alternate temporary data buffer during constants
and debug generation to accommodate the possibility of the user
setting an alternate data buffer.
* lib/jit_hppa-fpu.c, lib/jit_s390x.c, lib/jit_s390x-cpu.c,
lib/jit_s390x-fpu.c, lib/jit_sparc.c, lib/jit_sparc-fpu.c,
lib/jit_x86-sse.c, lib/jit_x86-x87.c: Implement jit_set_data.
* lib/jit_hppa-sz.c, lib/jit_sparc-sz.c, lib/jit_x86-sz.c,
lib/jit_s390x-sz.c: Update for several instructions that now
have a different maximum length due to jit_set_data.
* lib/jit_mips-fpu.c: Implement jit_set_data, but missing
validation on n32 and n64 abis (and/or big endian).
* lib/jit_mips-sz.c: Update for changes in o32.
* lib/jit_ppc-fpu.c: Implement jit_set_data, but missing
validation on Darwin PPC.
* lib/jit_ppc-sz.c: Update for changes in powerpc 32 and
64 bit.
* lib/jit_ia64-fpu.c: Implement untested jit_set_data.
* TODO: Add note to list ports that were not tested for the
new jit_set_data() feature, due to no longer having access
to them.
* check/nodata.c: New file implementing a simple test exercising
several different conditions created by jit_set_data().
* check/check.nodata.sh: New file implementing a wrapper
over the existing *.tst files, that runs all tests without
using a data buffer for constants; only meaningful (and
enabled) on architectures that used to store float/double
constants on a read only data buffer.
* configure.ac, check/Makefile.am: Update for the new test
cases.
* check/lightning.c: Implement the new "-d" option that
sets an internal flag to call jit_set_data() disable
constants and debug, that is, using only a pure code
buffer.
* libguile/vm.h:
* libguile/vm.c (default_max_stack_size, initialize_default_stack_size):
Remove the default stack limit. In this way, programs run from the
command line or outside of the REPL will have no soft stack limit.
(make_vm): Change `max_stack_size' field to be a stack of limits and
handlers.
(current_overflow_size, should_handle_stack_overflow)
(reset_stack_limit, wind_overflow_handler, unwind_overflow_handler)
(vm_expand_stack): If the stack surpasses a user-set limit, call the
user-specified handler within its outer stack limit.
(call-with-stack-overflow-handler): New interface.
* module/system/vm/vm.scm: Export call-with-stack-overflow-handler.
* libguile/Makefile.am (install-data-local): Rename to...
(install-data-hook): ... this. This guarantees that the rule runs
after libguile-2.0.so has been installed.
* libguile/Makefile.am (gen-scmconfig.$(OBJEXT)): When cross-compiling,
pass -DCROSS_COMPILING=1.
(c-tokenize.$(OBJEXT)): Likewise.
* libguile/c-tokenize.lex (%top): Include <config.h> only when
CROSS_COMPILING is undefined.
* libguile/gen-scmconfig.c: Likewise.
