There is an incorrect conditional compilation requirement that
<nl_types.h> be present for DAY_1 to be defined. This doesn't
agree with the LSB and causes make check to fail on Cygwin.
* libguile/i18n.c [HAVE_NL_TYPES_H]: modify conditional compilatiion
* libguile/expand.c (expand_letrec_helper): Factor out common code.
(expand_letrec): Use expand_letrec_helper.
(expand_letrec_star): New primitive syntax: letrec*.
* libguile/memoize.c (memoize): Add memoizer support for in-order letrec
(letrec*).
* module/ice-9/psyntax.scm (build-letrec): Another arg, `in-order?'.
(chi-body): Adapt to build-letrec change. We don't yet use letrec* for
internal definitions.
(letrec): Adapt to build-letrec change.
(letrec*): New expander.
* module/ice-9/psyntax-pp.scm: Regenerated.
* libguile/expand.h (SCM_EXPANDED_LETREC_IN_ORDER_P)
(SCM_MAKE_EXPANDED_LETREC): Add a new field to letrec, in-order?. Will
be used to support letrec*.
* libguile/expand.c (LETREC, expand_named_let, expand_letrec): Adapt
code.
* module/language/elisp/compile-tree-il.scm (compile-pair):
* module/ice-9/psyntax.scm (build-named-let, build-letrec): Pass #f for
in-order? to `make-letrec'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/language/tree-il.scm: Add letrec-in-order? accessor.
(parse-tree-il, unparse-tree-il): Parse and unparse an in-order?
letrec as `letrec*'.
(tree-il->scheme): Serialize letrec*.
* libguile/numbers.c (scm_integer_expt): Validate the first arg as a
number.
(scm_expt): Delegate to scm_integer_expt iff x is exact. Fixes
fractions.test, which I broke recently
* test-suite/tests/numbers.test ("integer-expt"): Add test for
(integer-expt #t 0).
* libguile/hashtab.c: Re-arrange functions to avoid the need for
pre-declaring character arrays with no length. Fixes compilation on
Compaq C V6.3-025. Thanks to Jay Krell for the report.
* module/ice-9/psyntax.scm (chi-install-global, chi-macro)
(eval-local-transformer): Now that we handle module hygiene through
syntax objects, there is no more need to record the current module
when installing syntax transformers.
* module/ice-9/psyntax-pp.scm: Regenerated (trickily).
* libguile/_scm.h: Bump objcode version for macro representation change.
* libguile/macros.c (scm_macro_transformer): Adapt to change in macro
representation.
* libguile/vm-i-scheme.c (ALIGNED_P): New macro.
(BV_FIXABLE_INT_REF, BV_INT_REF, BV_FLOAT_REF, BV_FIXABLE_INT_SET,
BV_INT_SET, BV_FLOAT_SET): Check the alignment of the pointer instead
of checking "i % size == 0". This fixes bus errors on
`sparc64-linux-gnu'.
* libguile/vm.c: Include <alignof.h>.
* libguile/foreign.c (scm_i_foreign_call): Fix the computation of
ARG_SIZE wrt. alignment. Arrange so that the address ARGS[i] is
aligned, rather than checking whether OFF is aligned. Have the RVALUE
be at least word-aligned, which fixes calls to `char'-returning
functions on `armv5tel-*-linux-gnueabi'.
* libguile/_scm.h (struct scm_aligned_cell)[__GNUC__]: New type.
(union scm_aligned_cell)[!__GNUC__]: New type.
(scm_t_aligned_cell): New type.
* libguile/vm.c (vm_dispatch_hook): Use it.
* libguile/read.c (scm_read_shebang): New function;
(scm_read_sharp): Call scm_read_shebang on '!', which delegates to
scm_read_scsh_block_comment as necessary.
* test-suite/tests/reader.test ("R6RS lexeme comment", "partial R6RS
lexeme comment"): New tests.

`vp->stack_limit' when possible.
* libguile/vm.c (VM_STACK_RESERVE_SIZE): New macro.
* test-suite/lib.scm (exception:vm-error): New variable.
* test-suite/tests/eval.test ("stack overflow"): New test prefix.
* libguile/expand.c (expand_lambda_star_case): Harmonize with tree-il,
expanding keywords to (aok? (kw name gensym) ...), not
(aok? (kw . index) ...).
* libguile/memoize.c (memoize): Process the (kw name gensym) format into
(kw . index).
* module/ice-9/psyntax.scm (build-lambda-case): Remove a
compile-versus-eval special case.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/eval.scm (primitive-eval):
* libguile/eval.c (scm_c_primitive_eval): Don't expect a memoized
expression -- expect either raw source or an *expanded* expression. We
handle memoization ourselves.
* libguile/expand.c (scm_macroexpand): Settle down into its proper name,
"macroexpand", even as we comment that it is but a fleeting boot
expander.
(scm_macroexpanded_p): New predicate for expanded code.
* libguile/expand.h: Add scm_macroexpanded_p.
* libguile/memoize.c (scm_memoize_expression): Require that the
expression be expanded.
(scm_init_memoize): Don't alias memoize-expression to macroexpand.
* module/ice-9/psyntax-pp.scm:
* module/ice-9/psyntax.scm: Always produce macroexpanded expressions,
and hand them to primitive-eval. No more calls to memoize-expression
here.
* test-suite/tests/optargs.test: Remove some tests, as unfortunately we
have no way to invoke the boot expander after boot.
* libguile/Makefile.am:
* libguile/init.c:
* libguile/expand.c:
* libguile/expand.h: Add new expander. The idea is that macroexpansion
is one thing, and whether to compile or interpret the result of that
is another thing.
* libguile/memoize.c: Adapt to expand as necessary, and then memoize
expanded source without worrying about syntax errors.
* module/ice-9/eval.scm (make-general-closure): Allow alt clauses to not
possess the full make-general-closure arity.
* libguile/memoize.c (patch_case_lambda, scm_m_case_lambda)
(scm_m_case_lambda_star): Add memoizers for case-lambda and
case-lambda*.
(unmemoize): Unmemoize lambdas with multiple arities.
* libguile/eval.c (prepare_boot_closure_env_for_apply):
(prepare_boot_closure_env_for_eval): Adapt to return both body and
env, so that case-lambda clauses can be selected appropriately.
(eval, boot_closure_apply): Adapt callers.
* module/ice-9/eval.scm (make-general-closure): Support multiple
arities.
* libguile/memoize.c (scm_m_lambda_star): Define lambda* in the
pre-psyntax env, and make it memoize lambda* expressions.

(error_invalid_keyword, error_unrecognized_keyword): New helpers.
(prepare_boot_closure_env_for_apply): Flesh out application of boot
closures with "full" arity.
(prepare_boot_closure_env_for_eval): Punt to
prepare_boot_closure_env_for_eval for the full-arity case.
* module/ice-9/eval.scm (make-fixed-closure): Rename from `closure', and
just handle fixed arities, where there is no rest argument..
(make-general-closure): New helper, a procedure, that returns a
closure that can take rest, optional, and keyword arguments.
(eval): Adapt to call make-fixed-closure or make-general-closure as
appropriate.
* test-suite/tests/optargs.test ("lambda* inits"): Test the memoizer as
well.
* libguile/memoize.c (scm_m_lambda, memoize_named_let)
(scm_memoize_lambda, unmemoize)
* libguile/eval.c (eval, prepare_boot_closure_env_for_apply)
(prepare_boot_closure_env_for_eval, boot_closure_apply):
* module/ice-9/eval.scm (primitive-eval): Change the format for memoized
lambda expressions, so as to allow, in the future, case-lambda* to be
supported by the evaluator.
* libguile/memoize.h:
* libguile/memoize.c (scm_memoize_begin, scm_memoize_if,
scm_memoize_lambda, scm_memoize_let, scm_memoize_quote,
scm_memoize_define, scm_memoize_with_fluids, scm_memoize_call,
scm_memoize_lexical_ref, scm_memoize_lexical_set,
scm_memoize_toplevel_ref, scm_memoize_toplevel_set,
scm_memoize_module_ref, scm_memoize_module_set): New functions, public
to Scheme but private to C. For use by psyntax, in the future.
* libguile/memoize.h:
* libguile/memoize.c (MAKMEMO_APPLY): Take the proc and args separately.
(scm_tc16_memoizer, SCM_MEMOIZER_P, SCM_MEMOIZER): New smob type, for
"syntax" like @apply that have normal evaluation order.
(memoize_env_ref_macro, memoize): Refactor to handle "memoizers"
generically.
Reorganize the list of SCM_SYNTAX forms.
Move @apply, @dynamic-wind, @call-with-current-continuation,
@call-with-values, @prompt handling down to be generic "memoizer" data
types.
(scm_memoizer_p, scm_memoizer): New functions, exposed to Scheme. Will
be used by psyntax.
* libguile/eval.c (scm_c_primitive_eval):
* module/ice-9/eval.scm (primitive-eval): Rely on the expander to
produce a memoized expression. If the expression is already memoized,
just pass it through (the equivalent of the old "noexpand" hack).
* libguile/memoize.c (scm_init_memoize): Initialize `memoize-expression'
as the initial binding of `macroexpand'.
* libguile/modules.c (scm_module_transformer): Before modules are
booted, look for `macroexpand', not `%pre-modules-transformer'.
* module/ice-9/boot-9.scm: No more %pre-modules-transformer. Loading
psyntax extends `macroexpand'.
(make-module): `macroexpand' is the default transformer.
* module/ice-9/psyntax.scm: No more `noexpand'.
(top-level-eval-hook, local-eval-hook): Instead of annotating with
noexpand, memoize the expression before handing it to primitive-eval.
(macroexpand): No more noexpand hack -- in its place we have another
hack, to memoize the result when running in eval mode.
* module/ice-9/psyntax-pp.scm: Regenerated.
* libguile/struct.c (scm_is_valid_vtable_layout): New private layout
validating function.
(scm_i_struct_inherit_vtable_magic): Do a more proper layout
validation, and don't abort.
* libguile/vm-i-system.c (assert-nargs-ee/locals): New instruction, a
combination of assert-nargs-ee and reserve-locals in the case in which
nreq and nlocs can both be represented in 8 bits.
* module/language/glil/compile-assembly.scm (glil->assembly): Add
compiler case.
* doc/ref/vm.texi (Function Prologue Instructions): Update docs.
* libguile/vm-engine.h (CHECK_OVERFLOW, CHECK_UNDERFLOW): Add
SCM_UNLIKELY blocks. Fix off-by-one error in CHECK_UNDERFLOW.
(PRE_CHECK_UNDERFLOW): New macro, for checking underflow before
accessing the current sp.
(POP): Use PRE_CHECK_UNDERFLOW.
