* libguile/vm-engine.c (fluid-set!): Fix name of opcode to correspond
with name of Tree-IL primitive. Fixes compilation of fluid-set! to
actually use the fluid-set! opcode.

* module/language/cps/compile-bytecode.scm (compile-function): Add
fluid-set! case.
* module/system/vm/assembler.scm: Update export name for
emit-fluid-set!.
* module/system/vm/assembler.scm (simple-uniform-vector?): array-length
fails for rank 0 arrays; fix the shape condition.
* test-suite/tests/arrays.test: Test reading of #0f64(x) in compilation
context.
* doc/ref/vm.texi (Inlined Atomic Instructions): New section.
* libguile/vm-engine.c (VM_VALIDATE_ATOMIC_BOX, make-atomic-box)
(atomic-box-ref, atomic-box-set!, atomic-box-swap!)
(atomic-box-compare-and-swap!): New instructions.
* libguile/vm.c: Include atomic and atomics-internal.h.

effects analysis needed.
* module/language/cps/reify-primitives.scm (primitive-module): Add case
for (ice-9 atomic).
* module/language/tree-il/primitives.scm (*effect-free-primitives*):
(*effect+exception-free-primitives*): Add atomic-box?.
* module/system/vm/assembler.scm: Add new instructions.
* test-suite/tests/atomic.test: Test with compilation and
interpretation.
* libguile/tags.h (scm_tc7_smob):
* module/system/base/types.scm (%tc7-smob): Tweak this value, just to
prove that it can be done. Remove scary comment.
* m4/mkstemp.m4: Remove.
* lib/mkstemp.c: Remove.
* lib/mkostemp.c: New file.
* m4/mkostemp.m4: New file.
* lib/Makefile.am:
* m4/gnulib-cache.m4:
* m4/gnulib-comp.m4: Remove mkstemp module, replace with mkostemp.
* libguile/fports.h:
* libguile/fports.c (scm_i_mode_to_open_flags): Factor out helper to
parse mode string to open flags.
(scm_open_file_with_encoding): Use the new helper.
* libguile/filesys.c:
(scm_i_mkstemp): Adapt to take optional second argument, being a mode
string. Use mkostemp.
(scm_mkstemp): Backwards compatible shim that calls scm_i_mkstemp.
* doc/ref/posix.texi:
* NEWS: Update.
* module/system/base/compile.scm (call-with-output-file/atomic): Pass
"wb" as mode, to cause O_BINARY to be added on MinGW.
* doc/ref/vm.texi (Top-Level Environment Instructions): Update
documentation.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump, sadly.
* module/system/vm/assembler.scm (*bytecode-minor-version*): Bump.
* libguile/vm-engine.c (define!): Change to store variable in dst slot.
* module/language/tree-il/compile-cps.scm (convert):
* module/language/cps/compile-bytecode.scm (compile-function): Adapt to
define! change.
* module/language/cps/effects-analysis.scm (current-module): Fix define!
effects. Incidentally here was the bug: in Guile 2.2 you can't have
effects on different object kinds in one instruction, without
reverting to &unknown-memory-kinds.
* test-suite/tests/compiler.test ("regression tests"): Add a test.
* module/system/base/compile.scm (call-with-output-file/atomic): Use the
permissions of the source file, if available, as the permissions of
the compiled file. Fixes#18477.
* module/system/vm/assembler.scm (immediate-bits): Fix a bug whereby
compiling to a 32-bit target from a 64-bit host would treat all
integers whose representation fit into 32 bits as immediates. This
would result in integer constants between #x20000000 and 0x3fffffff
being residualized in such a way that they would be loaded as negative
numbers.
* doc/ref/guile.texi: Add 2016 to user-visible copyright notice.
* module/ice-9/command-line.scm (version-etc): Bump 'copyright-year' to
2016.
* module/system/repl/common.scm (*version*): Add 2016 to the range of
copyright years.
* module/ice-9/command-line.scm (version-etc): Bump 'copyright-year' to
2015.
* module/system/repl/common.scm (*version*): Add 2015 to the range of
copyright years.
* module/system/base/types.scm (cell->object): Use 'get-bytevector-n'
instead of 'get-bytevector-all', so that the zero-length case does not
return EOF.
* module/statprof.scm: Remove most of the commentary, as it was
duplicated in the manual and was getting out of date.
(stats): Remove self-secs-per-call and cum-secs-per-call fields as
they can be computed from the other fields.
(statprof-call-data->stats): Adapt.
(statprof-stats-self-secs-per-call):
(statprof-stats-cum-secs-per-call): New functions.
(statprof-display/flat): Don't print the seconds-per-call fields, as
we are no longer stopping the clock around call counters. Anyway
these times were quite misleading.
(with-statprof): Deprecate. It took its keyword arguments at the
beginning; very complicated! Better to use the `statprof' function.
(`statprof' was introduced after `with-statprof' and then
`with-statprof' was adapted to use it.)
* doc/ref/statprof.texi (Statprof): Port this documentation away from
the automatically generated text and update it for the new interfaces
like #:display-style.
* module/system/base/syntax.scm (record-case): Remove comment that
referenced with-statprof. Add comment indicating that record-case
should be replaced.
* doc/ref/scheme-using.texi (Profile Commands): Update to mention
keyword arguments and to link to the statprof documentation.
* module/system/repl/debug.scm (print-locals): Adapt to
frame-binding-ref change.
* module/system/vm/frame.scm (<binding>): Add `frame' field.
(available-bindings): Capture the frame.
(binding-ref, binding-set!): New functions, accessing a local variable
value directly from a frame.
(frame-binding-ref, frame-binding-set!): Remove. As these are very
low-level debugging interfaces introduced in 2.0, never documented,
and quite tied to the VM, we feel comfortable making this change.
(frame-call-representation): Adapt to available-bindings change.
(frame-environment, frame-object-binding): Adapt to binding-ref
interface change.
* doc/ref/vm.texi (Stack Layout): Mention that slots can be re-used.
Update disassembly in example.
* doc/ref/api-debug.texi (Frames): Remove documentation for
frame-local-ref, frame-local-set!, and frame-num-locals. Replace with
documentation for frame-bindings, binding accessors, and binding-ref /
binding-set!.
* libguile/frames.h (scm_frame_num_locals, scm_frame_local_ref)
(scm_frame_local_set_x): Remove. As long as we are changing the
interface in a backward-incompatible way, we might as well remove
these.
* libguile/frames.c (scm_frame_num_locals, scm_frame_local_ref)
(scm_frame_local_set_x, scm_init_frames_builtins, scm_init_frames):
Arrange to make frame-local-ref et al private to frames.scm.
* module/system/vm/frame.scm: Load scm_init_frames_builtins extensions.
(frame-instruction-pointer-or-primitive-procedure-name): New public
function.
(frame-binding-ref, frame-binding-set!): Allow binding objects as
vars.
* module/system/repl/debug.scm (print-locals): Pass binding directly to
frame-binding-ref.
* module/statprof.scm (sample-stack-procs, count-call): Use new
frame-instruction-pointer-or-primitive-procedure-name function.
* module/system/vm/assembler.scm (define-byte-order-swapper): New
helper.
(byte-swap/2!, byte-swap/4!, byte-swap/8!): New functions.
(link-data): Swap bytes in uniform vectors on foreign byte orders.
* module/system/vm/assembler.scm (immediate-bits): Rename from
immediate?, and return the bits. Take asm argument so that we measure
what's an immediate not on the host but for the target. Adapt all
callers.
(write-immediate): Take bits instead of SCM object. Adapt callers.
(write-placeholder): New helper, to write bits for #f. Adapt callers
that wrote #f to use write-placeholder.
* module/system/vm/assembler.scm: Change define encoders for all of the
kinds of instructions and have the emit-foo procedures call the common
encoders. No change to public interface. This decreases the amount
of generated code in the assembler.
* libguile/vm-engine.c (BR_U64_SCM_COMPARISON): New helper.
(br-if-u64-<=-scm, br-if-u64-<-scm, br-if-u64-=-scm)
(br-if-u64->-scm, br-if-u64->=-scm): New instructions, to compare an
untagged u64 with a tagged SCM. Avoids many u64->scm operations.
* module/language/cps/compile-bytecode.scm (compile-function):
* module/language/cps/effects-analysis.scm:
* module/language/cps/type-fold.scm:
* module/system/vm/assembler.scm:
* module/system/vm/disassembler.scm (code-annotation, compute-labels):
* module/language/cps/primitives.scm (*branching-primcall-arities*): Add
support for new opcodes.
* module/language/cps/specialize-numbers.scm
(specialize-u64-scm-comparison): New helper.
* module/language/cps/specialize-numbers.scm (specialize-operations):
Specialize u64 comparisons.
* module/language/cps/types.scm (true-comparison-restrictions): New helper.
(define-comparison-inferrer): Use the new helper. Add support for
u64-<-scm et al.
* module/system/vm/assembler.scm (check-urange, check-srange): New
helpers.
(pack-u8-u24, pack-u8-s24, pack-u1-u7-u24, pack-u8-u12-u12):
(pack-u8-u8-u16, pack-u8-u8-u8-u8): Use the new helpers. Not only
makes the code nicer but also reduces register pressure.
* module/system/vm/assembler.scm (<asm>): Instead of writing words into
a list of fixed-size buffers, use a growable vector.
(expand, emit): Instead of assuming that there is enough space for
only one word, check that there is space for the entire instruction at
the beginning.
* libguile/vm-engine.c (logsub): New op.
* module/language/cps/effects-analysis.scm (logsub):
* module/language/cps/types.scm (logsub):
* module/system/vm/assembler.scm (system): Add support for the new op.
* module/language/tree-il/compile-cps.scm (canonicalize):
Rewrite (logand x (lognot y)) to (logsub x y).
* libguile/vm-engine.c (bv-s8-ref, bv-s16-ref, bv-s32-ref, bv-s64-ref):
Unbox index and return unboxed S32 value.
(bv-s8-set!, bv-s16-set!, bv-s32-set!, bv-s64-set!): Unbox index and
take unboxed S32 value.
(bv-u8-ref, bv-u16-ref, bv-u32-ref, bv-u64-ref)
(bv-s8-set!, bv-s16-set!, bv-s32-set!, bv-s64-set!): Likewise, but
with unsigned values.
(bv-f32-ref, bv-f32-set!, bv-f64-ref, bv-f64-set!): Use memcpy to
access the value so we don't have to think about alignment. GCC will
inline this to a single instruction on architectures that support
unaligned access.
* libguile/vm.c (vm_error_out_of_range_uint64)
(vm_error_out_of_range_int64): New helpers.
* module/language/cps/slot-allocation.scm (compute-var-representations):
All bytevector ref operations produce untagged values.
* module/language/cps/types.scm (define-bytevector-accessors): Update
for bytevector untagged indices and values.
* module/language/cps/utils.scm (compute-constant-values): Fix s64
case.
* module/language/tree-il/compile-cps.scm (convert): Box results of all
bytevector accesses, and unbox incoming indices and values.
