Guile Emacs Lisp previously kept macros in a separate macro slot; now
macros are stored as macro objects in the function slot for
compatibility with other implementations.
* module/language/elisp/compile-tree-il.scm (macro-slot): Remove.
(is-macro?): Check that the argument is a symbol. Now-unnecessary
check removed in `compile-tree-il'.
(macro?, define-macro!, get-macro): Store macro definitions in the
function slot, not in a separate macro slot.
* module/language/elisp/runtime.scm (built-in-macro): Wrap the macro
function in a macro object (i.e., cons the symbol `macro' onto it).
* module/language/elisp/runtime/function-slot.scm: Move contents to
"subrs.scm". Re-export function and macro definitions instead of
defining functions directly in this module.
* module/language/elisp/runtime/macro-slot.scm: Move contents to
"macros.scm" and remove.
* module/language/elisp/runtime/macros.scm: New file containing macro
definitions from "macro-slot.scm".
* module/language/elisp/runtime/subrs.scm: New file containing function
definitions from "function-slot.scm".

* module/language/ecmascript/tokenize.scm (syntax-error): Reorder args
to throw vals in the right order.

variable names"): New test.
["unused-toplevel"]("special variable names"): New test.
* module/language/tree-il/analyze.scm (format-analysis): Don't warn on
non-literal format string if the format string is a lexical ref to a
variable named "fmt". A slight hack, but effective :)
* module/system/repl/command.scm (display-stat): Rename the format
string to "fmt".
* module/language/tree-il/analyze.scm (&syntax-error): New variable.
(format-string-argument-count): Throw to &SYNTAX-ERROR when a syntax
error in a format string is encountered.

"unexpected ~]"): New tests.
["unterminated ~{...~}"]: New test.
* module/language/tree-il/analyze.scm (format-analysis): Add new
sub-warnings: `wrong-port', `wrong-format-string',
`non-literal-format-string', and `wrong-num-args'.
* module/system/base/message.scm (%warning-types)[format]: Handle
them.
* test-suite/tests/tree-il.test ("warnings")["wrong port arg",
"wrong format string", "non-literal format string",
"wrong number of args"]: New tests.
* module/language/tree-il/analyze.scm (format-string-argument-count):
Return two values, the minimum and maximum number of arguments.
Add support for most of `format' escapes, including conditionals.
(format-analysis): Adjust accordingly.
* module/system/base/message.scm (%warning-types)[format]: Take two
arguments, MIN and MAX, instead of EXPECTED. Display warning
accordingly.
* test-suite/tests/tree-il.test ("warnings")["format"]("~%, ~~, ~&, ~t,
~_, and ~\\n", "~{...~}", "~{...~}, too many args", "~@{...~}",
"~@{...~}, too few args", "~(...~)", "~v", "~v:@y", "~*", "~?",
"complex 1", "complex 2", "complex 3"): New tests.
("conditionals"): New test prefix.
* libguile/vm-i-scheme.c (symbol?, vector?): New
instructions. Renumbered the rest.

* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
* module/ice-9/psyntax.scm (binding-type, binding-value): Define using

(*interesting-primitive-names*, *effect-free-primitives*)
(*effect+exception-free-primitives*): Add symbol? and vector?
inlines.

* module/language/tree-il.scm (tree-il->scheme): Expand out to letrec*,
as it doesn't matter, and this avoids a let when running through the
evaluator.
* module/ice-9/boot-9.scm (make-struct/no-tail): Define a version of
this function. Because during optimization we resolve make-struct to
make-struct/no-tail, we need an implemented make-struct/no-tail if we
are to be able to run scheme made from tree-il->scheme.
* module/language/tree-il/compile-glil.scm (*primcall-ops*): Remove
variable-set case, as there is no "variable-set!" primitive.
(flatten): Add a special hack for variable-set!. Ugly, I know.

* module/language/tree-il/compile-glil.scm (flatten): Add support for
compiling letrec* in its unoptimized form.
* module/language/tree-il/fix-letrec.scm (simple-expression?):
Parameterize, so that letrec* will not treat `(car x)' as primitive
(because it could raise an exception).
(partition-vars): Lump unreferenced vars in with complex vars, when
compiling letrec*.
(fix-letrec!): No need to evaluate inits within a let for letrec*.
* module/language/tree-il/primitives.scm
(effect+exception-free-primitive?): New predicate, like
effect-free-primitive?, but excludes accessors that could raise
exceptions.
* 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*.

(parse-tree-il, unparse-tree-il): Parse and unparse an in-order?
letrec as `letrec*'.

make-prompt-tag as interesting and effect-free.

case for inlining conditional expressions.

(borrow-core-vtables, <tree-il>): When tree-il loads, override the
printers for macroexpanded structures.
* 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.
* module/language/tree-il.scm (<tree-il>): Rename `vars' fields of
<let>, <letrec>, <fix>, and <lambda-case> to `gensyms'. For clarity,
and to match <lexical-ref>.
* module/language/tree-il.scm:
* module/language/tree-il/analyze.scm:
* module/language/tree-il/compile-glil.scm:
* module/language/tree-il/fix-letrec.scm:
* module/language/tree-il/inline.scm: Update all callers.
* module/system/base/language.scm (<language>): Remove the `version'
field from languages. It just wasn't useful.
* module/language/assembly/spec.scm:
* module/language/brainfuck/spec.scm:
* module/language/bytecode/spec.scm:
* module/language/ecmascript/spec.scm:

* module/language/objcode/spec.scm:
* module/language/scheme/spec.scm:
* module/language/tree-il/spec.scm:
* module/language/value/spec.scm: Remove #:version from all language
definitions. Shorten some language names (e.g. "Guile Scheme" ->
"Scheme").
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump for make-struct
change.
* libguile/struct.c (scm_i_alloc_struct): Use scm_words instead of
scm_gc_malloc to simplify the code and inline the call to GC_MALLOC.

make-struct/no-tail to make-struct.
* module/language/tree-il/primitives.scm (define-primitive-expander):
Allow a conditional branch of #f to aboirt inlining.
(make-struct): Expand into make-struct/no-tail in the case that
tail-size is 0.
* libguile/vm-i-scheme.c (make-struct): Adapt to always assume tail-size
is 0. Inline allocation if possible. Don't decrement the SP past live
objects on the stack, which could cause GC to miss references. Use the
NULLSTACK macro.
* libguile/procprop.h (scm_sym_arity): Deprecate. I didn't move it to
deprecated.h though, because that might have some boot implications --
though I didn't check.
* libguile/procprop.c (scm_procedure_properties)
(scm_set_procedure_properties_x, scm_procedure_property)
(scm_set_procedure_property_x): Deprecate access to a procedure's
arity via procedure-properties. Users should use
procedure-minimum-arity.
* module/ice-9/channel.scm (eval):
* module/ice-9/session.scm (arity):
* module/language/tree-il/analyze.scm (validate-arity): Fix up instances
of (procedure-property x 'arity) to use procedure-minimum-arity.
* libguile/programs.h:
* libguile/programs.c (scm_program_name): Remove. procedure-name is
sufficient.

procedure-name.
* module/ice-9/documentation.scm (object-documentation): Just use
procedure-documentation, without special cases for programs.
