| * | Add thread local fluids...* libguile/fluids.h (struct scm_dynamic_state): Add thread_local_values
table. Thread locals are flushed to a separate thread-local table.
The references are strong references since the table never escapes the
thread.
(scm_make_thread_local_fluid, scm_fluid_thread_local_p): New
functions.
* libguile/fluids.c (FLUID_F_THREAD_LOCAL):
(SCM_I_FLUID_THREAD_LOCAL_P): New macros.
(restore_dynamic_state): Add comment about precondition.
(save_dynamic_state): Flush thread locals.
(scm_i_fluid_print): Print thread locals nicely.
(new_fluid): Add flags arg.
(scm_make_fluid, scm_make_fluid_with_default, scm_make_unbound_fluid):
Adapt.
(scm_make_thread_local_fluid, scm_fluid_thread_local_p): New
functions.
(fluid_set_x): Special flushing logic for thread-locals.
(fluid_ref): Special cache miss logic for thread locals.
* libguile/stacks.c (scm_init_stacks):
* libguile/throw.c (scm_init_throw): %stacks and %exception-handler are
thread-locals.
* libguile/threads.c (guilify_self_2): Init thread locals table.
* test-suite/tests/fluids.test ("dynamic states"): Add test.
* doc/ref/api-control.texi (Fluids and Dynamic States): Add link to
Thread-Local Variables.
* doc/ref/api-scheduling.texi (Thread Local Variables): Update with real
thread-locals.
* NEWS: Update.

| * | Cheaper fluid-ref cache...* libguile/cache-internal.h (struct scm_cache_entry): Add needs_flush
member.
(scm_cache_evict_1): Clear needs_flush on newly evicted entry.
(scm_cache_insert): Propagate needs_flush to new entry.
* libguile/fluids.c (restore_dynamic_state): Mark all restored entries
as needing a flush.
(save_dynamic_state): Only cons on "needs_flush" entries to the
resulting dynamic state. The result is the same as before but
avoiding the refq on the weak table.
(fluid_set_x): Propagate needs_flush down to the cache.
(fluid_ref): When adding entry to cache, use needs_flush==0.
(scm_fluid_set_x, scm_fluid_unset_x, scm_swap_fluid, swap_fluid): Use
needs_flush==1.

function.
* libguile/fluids.c (saved_dynamic_state_ref): New helper.
(scm_fluid_ref): Fix docstring.
(scm_fluid_ref_star): New function allowing access to previous values
for a fluid.

* libguile/fluids.h: Add scm_fluid_ref_star and scm_dynamic_state_ref.
* libguile/stacks.c (scm_stack_id): Adapt to %stacks not being a chain.
* libguile/throw.c (catch, throw_without_pre_unwind): Adapt to
%exception-handlers not being a chain.
* module/ice-9/boot-9.scm (catch, dispatch-exception): Instead of having
%exception-handlers be a chain, use fluid-ref* to access the chain
that is in place at the time the exception is thrown. Prevents
unintended undelimited capture of the current exception handler stack
by a delimited "catch".
(%start-stack): Similarly, don't be a chain.
* module/system/repl/debug.scm (frame->stack-vector):
* module/system/repl/error-handling.scm (call-with-error-handling):
* module/ice-9/save-stack.scm (save-stack): Adapt to %stacks not being a

tests.

| * | Reimplement dynamic states...There are two goals: one, to use less memory per dynamic state in order
to allow millions of dynamic states to be allocated in light-weight
threading scenarios. The second goal is to prevent dynamic states from
being actively mutated in two threads at once. This second goal does
mean that dynamic states object that escape into scheme are now copies
that won't receive further updates; an incompatible change, but one
which we hope doesn't affect anyone.

Enlarge from 32 kB to 512 or 1024 kB, depending on word size. Reduces

| * | Remove with-fluids; replaced by with-fluid* and inlined push-fluid primops...* libguile/vm-i-system.c (push-fluid, pop-fluid):
* doc/ref/vm.texi (Dynamic Environment Instructions): Rename wind-fluids
to push-fluid, and unwind-fluids to pop-fluid. They now only work on
one fluid binding at a time.
* module/ice-9/boot-9.scm (with-fluid*): Implement in Scheme in terms of
primcalls to push-fluid and pop-fluid.
(custom-throw-handler, catch, with-throw-handler): Use with-fluid*
instead of with-fluids, as with-fluids is no longer available before
psyntax is loaded.

| * | | the dynamic stack is really a stack now, instead of a list...* libguile/dynstack.h:
* libguile/dynstack.c: New files, implementing the dynamic stack as a
true stack instead of a linked list. This lowers the cost of
dynwinds: frames, winders, prompts, with-fluids, and dynamic-wind.
For the most part, we allocate these items directly on the stack.
* libguile/dynwinds.h:
* libguile/dynwinds.c: Adapt all manipulators of the wind stack to use
interfaces from dynstack.c. Remove heap-allocated winder and frame
object types.
(scm_dowinds, scm_i_dowinds): Remove these. The first was exported,
but it was not a public interface.
* libguile/continuations.c:
* libguile/continuations.h (scm_t_contregs): Continuation objects
reference scm_t_dynstack* values now. Adapt to the new interfaces.
* libguile/control.c:
* libguile/control.h: There is no longer a scm_tc7_prompt kind of object
that can be allocated on the heap. Instead, the prompt flags, key,
and registers are pushed on the dynwind stack. (The registers are
still on the heap.) Also, since the vm_cont will reference the
dynwinds, make the partial continuation stub take just one extra arg,
instead of storing the intwinds separately in the object table.
* libguile/fluids.c:
* libguile/fluids.h: No more with-fluids objects; instead, the fluids go
on the dynstack. The values still have to be on the heap, though.
(scm_prepare_fluids, scm_swap_fluids): New internal functions,
replacing scm_i_make_with_fluids and scm_i_swap_with_fluids.
* libguile/print.c: Remove prompt and with-fluids printers.
* libguile/tags.h: Revert prompt and with-fluids tc7 values to what they
were before they were allocated.
* libguile/vm-i-system.c (partial_cont_call): Just pop the vmcont, the
intwinds will not be passed as a second arg. Rewind the dynamic stack
from within the VM, so that any rewinder sees valid prompt entries.
(call_cc, tail_call_cc): Adapt to pass the dynstack to
scm_i_vm_capture_stack.
(prompt, wind, unwind, wind_fluids, unwind_fluids): Adapt to the new
interfaces.
* libguile/vm.h (scm_i_capture_current_stack): Rename from
scm_i_vm_capture_continuation.
(scm_i_vm_capture_stack): Take a dynstack as an argument.
* libguile/vm.c (vm_reinstate_partial_continuation): Don't wind here, as
that could result in winders seeing invalid prompts.
* libguile/eval.c:
* libguile/root.c:
* libguile/stacks.c:
* libguile/threads.c:
* libguile/threads.h:
* libguile/throw.c: Adapt other users of dynwinds to use the dynstack.

| * | | add SCM_{PACK,UNPACK}_POINTER...* libguile/tags.h (SCM_UNPACK_POINTER, SCM_PACK_POINTER): New macros.
The old SCM2PTR and PTR2SCM were defined in such a way that
round-tripping through a pointer could lose precision, even in the
case in which you weren't interested in actually dereferencing the
pointer, it was simply that you needed to plumb a SCM through APIs
that take pointers. These new macros are more like SCM_PACK and
SCM_UNPACK, but for pointer types. The bit representation of the
pointer should be the same as the scm_t_bits representation.
* libguile/gc.h (PTR2SCM, SCM2PTR): Remove support for (old) UNICOS
pointers. We are going to try tagging the SCM object itself in the

| * | fluids are tc7 objects...If you're wondering what I'm doing, I'm trying to eventually reimplement
smobs in terms of structs, so that applicable smobs can just follow the
applicable struct dispatch path. But to do that I have to get structs
initialized before things that use smobs, which means transforming a
bunch of smobby things to tc7 things. But this transformation is good
for performance anyway, and we currently have a glut of unused tc7s,
so here we go...
* libguile/tags.h (scm_tc7_fluid, scm_tc7_dynamic_state): Fluids (and
dynamic states) now have tc7s.
* libguile/fluids.h: Remove scm_fluids_prehistory, and add internal
scm_i_fluid_print. Update a comment.
* libguile/fluids.c: Update for tc7 representation. Also remove the next
pointers while we're at it, as they aren't used in the new BDW GC.
* libguile/eq.c (scm_equal_p): Remove the hashtable case. Hashtables
could never be equal? before, I don't see why to add stubs doing the
same thing now.
* libguile/print.c (iprin1):
* libguile/gc.c (scm_i_tag_name):
* libguile/evalext.c (scm_self_evaluating_p): Add fluid and
dynamic_state cases.
* libguile/goops.h: Remove scm_class_hashtable; it will be static.
* libguile/goops.c: Make <hashtable> static, and add <fluid> and
<dynamic-state> classes.
* libguile/hashtab.h:
* libguile/hashtab.c: Remove scm_i_hashtable_equal_p.
* libguile/init.c (scm_i_init_guile): Remove call to fluids_prehistory.
