* doc/ref/compiler.texi: Remove mention of <dynwind>.
* libguile/eval.c (eval): Remove SCM_M_DYNWIND case.
* libguile/expand.c: Remove scm_sym_at_dynamic_wind.
* libguile/memoize.c (do_wind, do_unwind): A couple of hacky subrs. If
we see a wind or unwind primcall, we expand to a call of a quoted subr
value. It works and removes a kind of memoized value from the
interpreter. For the compiler,primcalls to wind and unwind are
handled specially.
(MAKMEMO_DYNWIND): Remove.
(scm_tc16_memoizer): Remove. Yay!
(memoize): Remove speculative lookup for toplevels to see if they are
memoizers: there are no more memoizers. Memoize calls to the wind and
unwind primitives.
(m_dynamic_wind): Remove.
(unmemoize): Remove dynwind case.
(scm_init_memoize): Add wind and unwind local definitions.
* module/ice-9/boot-9.scm (dynamic-wind): Reimplement in terms of "wind"
and "unwind" primitives. These primitives are not exposed to other
modules.
* module/ice-9/eval.scm (primitive-eval): Remove dynwind case.
* module/language/scheme/decompile-tree-il.scm (do-decompile):
(choose-output-names): Remove dynwind cases.
* module/language/tree-il.scm: Remove <dynwind>. Yaaay!
* module/language/tree-il/analyze.scm (analyze-lexicals): Remove dynwind
cases.
* module/language/tree-il/compile-glil.scm (*primcall-ops*): Add wind
and unwind.
(flatten-lambda-case): Remove dynwind case. Yay!
* module/language/tree-il/cse.scm (cse):
* module/language/tree-il/debug.scm (verify-tree-il):
* module/language/tree-il/effects.scm (make-effects-analyzer):
* module/language/tree-il/peval.scm (singly-valued-expression?, peval):
Remove <dywind> cases. Inline primcalls to dynamic-wind. Add
constant folding for thunk?.
* module/language/tree-il/primitives.scm (*interesting-primitive-names*):
Remove @dynamic-wind, and add procedure? and thunk?.
(*effect+exception-free-primitives*): Add procedure? and thunk?.
(*multiply-valued-primitives*): Remove @dynamic-wind.
Remove @dynamic-wind expander.
* test-suite/tests/peval.test ("partial evaluation"): Update tests for
dynwind desugaring.
