improved error message for compile-whole-program and
compile-whole-library when a top-level expression is discovered while
processing a wpo file.

- fixed failure to install examples for tarball installs
Mf-install.in
- improved packaging support:
replaced bintar script with bintar directory and make file;
tarballs are created via "make create-tarball" and are placed in
the workarea's bintar directory. added rpm directory and make
file for creating RPMs via "make create-rpm". added pkg directory
and make file for creating OSX packages via "make create-pkg".
bintar (removed), bintar/Makefile (new), rpm/Makefile (new),
pkg/Makefile (new), pkg/rmpkg (new), workarea, checkin, newrelease,
Makefile.in, Makefile-workarea.in.
original commit: fdff97d15cd827eb8fbef200c0f495a4bfaefff3
added fix for whole program/library compilation bug with help from
@owaddell who originally reported the problem in issue 386. this bug
arises from the way the parts of the combined library, and their
binary dependencies, are invoked when one of the constituent libraries
is invoked. consider, for example, a combined library that contains
(A) and (B), where (B) depends on a binary library (C). depending on
the sort order of (A) and (B), which may be unconstrained in the
partial ordering established by library dependencies, invoking (A) may
result in the invoke code for (B) being run first, without (B) ever
being explicitly invoked. this can result in bindings required from
(C) by the invoke code in (B) to be unbound. even in the case where
(A) comes before (B) in the topological sort, if they are combined
into the same cluster, (B)'s invoke code will be run as part of
invoking (A). the solution is two part: first we extend the invoke
requirements of the first library in the cluster to include the binary
libraries that precede it in the topological sort and add a dependency
on the first library in the cluster to all of the other libraries in
the cluster. this means no matter which library in the cluster is
invoked first, it will cause the first library to be invoked, in turn
ensuring the binary libraries that precede it are invoked. when there
are multiple clusters, a dependency is added from each cluster to the
first library in the cluster that precedes it. this ensures that
invoking a library in a later cluster first, will still cause all of
the dependencies of the previous clusters to be invoked. ultimately,
these extra dependencies enforce an ordering on the invocation of the
source and binary libraries that matches the topological sort, even if
the topological sort was under constrained. to maintain the property
that import requirements are a superset of the invoke and visit
requirements, we also extend the import requirements to include the
extended invoke requirements. the import requirements are also added
to the dependency graph to further constrain the topological sort and
ensure that we do not introduce artificial cycles in the import graph.

on p to account for the procedure? check at optimize-level 2.
cpletrec.ss
- fixed bug in check-prelex-flags: was hardwiring $cpcheck-prelex-flags
"after" argument to 'uncprep rather than passing along its argument.
compile.ss
- commented out local definition of sorry! so that problems detected
by $cpcheck-prelex-flags actually result in a raised exception.

InstallPrefix, since it didn't and can't play well with the
generated config.h. Instead removed InstallPrefix entirely so
it isn't an attractive hazzard.

controversial, unless I damaged something in the process of integrating
them with other recent changes. the user's guide and release notes
have been updated as well to reflect the changes of interest to end
users.
- the body of load-library is now wrapped in a $pass-time with
to show the time spent loading libraries separately from the time
spent in expand.
syntax.ss
- interpret now plays the pass-time game
interpret.ss
- added compile-time-value? predicate and
compile-time-value-value accessor
syntax.ss, primdata.ss,
8.ms, primvars.ms, root-experr*
- $pass-stats now returns accurrate stats for the currently timed
pass.
7.ss
- compile-whole-program and compile-whole-library now propagate
recompile info from the named wpo file to the object file
to support maybe-compile-program and maybe-compile-library in
the case where compile-whole-{program,library} overwrites the
original object file.
compile.ss,
7.ms, mat.ss, primvars.ms
- replaced the ancient and unusable bintar with one that creates
a useful tarball for binary installs
bintar
- generated Mf-install InstallBin (InstallLib, InstallMan) now
correctly indirects through InstallPrefix if the --installbin
(--installlib, --installman) configure flag is not present.
src/configure
- removed definition of generate-procedure-source-information
patch.ss
- guardian tconc cells are now allocated in generation 0 in the hope
that they can be released more quickly.
gc.c
- added ftype-guardian syntax: (ftype-guardian A) creates a new
guardian for ftype pointers of type A, the first base field (or
one of the first base fields in the case of unions) of which must
be a word-sized integer with native endianness representing a
reference count. ftype pointers are registered with and retrieved
from the guardian just like objects are registered with and
retrieved from any guardian. the difference is that the garbage
collector decrements the reference count before resurrecting an
ftype pointer and resurrects only those whose reference counts
become zero, i.e., are ready for deallocation.

- fixed a bug in automatic recompilation handling of missing include
files specified with absolute pathnames or pathnames starting with
"./" or "..": was erroring out in file-modification-time with a
file-not-found or other exception rather than recompiling.
syntax.ss,
7.ms, root-experr*, patch*
- changed inline vector-for-each and string-for-each code to
put the last call to the procedure in tail position, as was
already done for the library definitions and for the inline
code for for-each.
cp0.ss,
5_4.ms, 5_6.ms
- the compiler now generates better inline code for the bytevector
procedure. instead of one byte memory write for each argument,
it writes up to 4 (32-bit machines) or 8 (64-bit machines) bytes
at a time, which almost always results in fewer instructions and
fewer writes.
cpnanopass.ss,
bytevector.ms
- packaged unchanging implicit reader arguments into a single record
to reduce the number of arguments.
read.ss
- recoded run-vector to handle zero-length vectors. it appears
we're not presently generating empty vectors (representing empty
groups), but the fasl format permits them.
7.ss
original commit: 7be1d190de7171f74a1ee71e348d3e6310392686
- fixed a bug in which instantiating a static foreign-callable code object
fails with an invalid memory reference because the collector has
discarded its relocation information. foreign-callable code objects
are now flagged as "templates", and the collector now refuses to
discard relocation information for code objects marked as templates
when copying them to the static generation.

still usable for bootstrapping)

fix#389 (apply doesn't throw exception when last argument isn't a list)
fold-primref and fold-primref2 ignored app-convention when
attempting to fold certain primitive calls in 'test and 'effect
context and when falling back on the default primitive handler.
We now residualize primitive references if the app-convention
is not 'call. The original fold-primref2 already bypassed the
inline handler when the app-convention was not 'call.

The `dofretu...*` intrinsics used %ac1 without declaring it as a used
registers, which effectively broke register allocation for handling
string/bytevector foreign-call results or callable arguments.
original commit: 993fb9036acad5445319f458fd971b1a1d8e9f84
Add a parameter to constrain the compiler (off by default) to
implement `+`, `*`, and variants as left-associative when given
multiple arguments.

In safe compilation modes, avoid turning an error like
(let ([x (values 1 2)]) x)
or
(car (list (values 1 2)))
into a program that returns multiple values or
(if (list (values 1 2)) 3 4)
into a program that returns without an error.
In addition, refrain from moving an expression from a non-tail
position within a procedure to a tail position, unless the expression
is not only single valued but also gauarnteed not to inspect the
immediate continuation (e.g., using `call/cc` and comparing the result
to a previously captured continuation). This constraint applies even
in unsafe compilation modes, because the intent it to provide some
guarantees about non-tail positions to complement existing guarantees
of tail positions.

Also adds `get-initial-thread`, since threa values are useful with
`compute-size[-increments]`.
Changes the compiler to inline `weak-pair?` and `ephemeron-pair?`,
since that provides better performance for `compute-size-increments`.

When writing a fasl stream, add extra graph points as needed
to limit recursive reading to about 500 non-tail recursions.

Also, for completeness, correct the listing of callee-save registers
in callable return for x86 & x86_64.

- when thread_get_room exhausts the local allocation area, it now
goes through a common path with S_get_more_room to allocate a new
local allocation area when appropriate. this can greatly reduce
the use of global allocation (and the number of tc mutex acquires
in threaded builds) when a lot of small objects are allocated by
C code with no intervening Scheme-side allocation or dirty writes.
