* include/lightning.h, include/lightning/jit_private.h,
lib/jit_names.c, lib/lightning.c: Add initial support
for the new jit_va_start, jit_va_arg, jit_va_arg_d, and
jit_va_end interfaces. The jit_va_start call is supposed
to return a va_list compatible pointer, but not yet
decided if it will be "declared" stdarg compatible,
as for now only x86 support has been added (and should
be compatible), but issues may arise on other backends.
* check/lightning.c: Add wrappers to call the new jit_va_*
interfaces.
* lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
jit_va_* for x86.
* lib/jit_x86-sz.c: Add fields, but not yet fully updated,
as this is an intermediate commit.
* lib/jit_aarch64-sz.c, lib/jit_aarch64.c,
lib/jit_alpha-sz.c, lib/jit_alpha.c,
lib/jit_arm-sz.c, lib/jit_arm.c,
lib/jit_hppa-sz.c, lib/jit_hppa.c,
lib/jit_ia64-sz.c, lib/jit_ia64.c,
lib/jit_mips-sz.c, lib/jit_mips.c,
lib/jit_ppc-sz.c, lib/jit_ppc.c,
lib/jit_s390-sz.c, lib/jit_s390.c,
lib/jit_sparc-sz.c, lib/jit_sparc.c: Prepare for the
new jit_va_* interfaces. Not yet implemented, and will
cause an assertion if used.
* check/va_list.tst: Simple early test case, that works
on x86_64, x32, ix86, cygwin, and cygwin64.
* module/language/cps/intset.scm (make-atomic-reference)
(get-atomic-reference, set-atomic-reference!): New functions.
(*branch-size-with-edit*, *edit-index*): New constants.
(<transient-intset>): New data type.
(new-branch, clone-branch-and-set): Adapt to set edit field.
(transient-intset, persistent-intset): New exports.
(intset-add!): New interface, supporting "transient" intsets.
(intset-ref, intset-next, intset-prev, intset-fold, intset-fold2):
Work with transients.
* module/language/cps/intmap.scm (make-atomic-reference):
(get-atomic-reference, set-atomic-reference!): New helpers.
(*branch-size-with-edit*, *edit-index*): Branches now have a trailing
field, an atomic reference to their owner.
(<transient-intmap>): New record type. A mutable intmap.
(new-branch): Set the "edit" field on the branch.
(clone-branch-and-set): No editor for this field.
(assert-readable!, writable-branch): New helpers.
(transient-intmap, persistent-intmap): New exported functions.
(intmap-add!): New function.
(intmap-next, intmap-prev, intmap-ref): Work on transient intmaps.
(intmap-fold): Persist the intmap before folding over it.
* module/language/cps/intmap.scm (*branch-bits*): Switch to 32-way
branching. Marginally faster on lookup, and creation costs can be
amortized via using the transient interface. Marginal speedup for
assembler.scm compilation.
* module/language/cps/intmap.scm (meet-error): New helper.
(intmap-add, intmap-union, intmap-intersect): The "meet" argument is
optional and defaults to meet-error.
* module/language/cps.scm ($rec): Replace $letrec with $rec, which is an
expression, not a term. This means that the names bound by the letrec
appear twice: once in the $rec term, and once in the continuation.
This is not very elegant, but the situation is better than it was
before. Adapt all callers.
* doc/ref/compiler.texi (CPS in Guile): Incomplete documentation
updates. I'll update these later when the IL settles down.
* module/ice-9/eval.scm (primitive-eval): Factor out primitive=?
helper. Simplify compile-top-call. Add compile-top-branch for
primcall branches, so the compiler can see the specialized branch
operator.
* module/ice-9/eval.scm (primitive-eval): Lazily compile lambda bodies.
Special-case calls to top-level or module variables, and recognize
some of those calls as primcalls. In that case, emit closures with
the primcalls.
* module/language/cps/compile-bytecode.scm (optimize, compile-bytecode):
Marginally improve bootstrap memory usage by not retaining stale
copies of already-rewritten terms.
* libguile/libguile-2.2-gdb.scm (vm-frame-function-name): Don't default
to the address, as we will have better identifying info via the file
name.
(vm-frame-source): New helper.
(compile-time-cond): For some reason "else" matching wasn't working;
punt and use expressions.
(snarfy-frame-decorator): Rename from decorator, and adapt to new
version of Guile frame filter patch.
(vm-frame-filter): Adapt to frame filter changes, and fill in source
info.
* libguile/arrays.c (scm_i_print_array): Print the dimension whenever
the array is a true scm_tc7_array.
* test-suite/tests/arrays.test: Check that non-vector 1D arrays print as
expected.
* include/lightning.h, include/lightning/jit_private.h,

lib/jit_sparc-cpu.c, lib/jit_sparc.c,
lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new
jit_allocar(offs, size) interface, that receives
two integer registers arguments, allocates space
dynamically in the stack, returns the offset in
the first argument, and uses the second argument
for the size in bytes of the memory to be allocated.
* check/allocar.ok, check/allocar.tst: New files
implementing test cases for the new jit_allocar
interface.
* check/Makefile.am, check/lightning.c: Update for
the new test case and interface.
* doc/body.texi: Add documentation of the new
interface.
* include/lightning/jit_x86.h, lib/jit_x86-cpu.c,
lib/jit_x86-x87.c: No longer make st(7) available.
Need to keep one x87 slots empty to avoid exceptions.
This has the side effect of no longer needing the
hackish emms instruction before a function call.
* libguile/libguile-2.2-gdb.scm (make-scm-pretty-printer-worker):
(%scm-pretty-printer): Refactor to avoid printing all struct / array
fields by hinting these as arrays. The resulting print is not as
faithful to the original data, but that's probably OK.
These features depend on a patch to GDB that has not been merged yet.
If GDB doesn't support the annotator/filter interface, the code have no
effect.
* libguile/libguile-2.2-gdb.scm (compile-time-cond): New helper.
(snarfy-frame-annotator): Simple annotator that gives subr names for
snarfed gsubrs.
(vm-frame-filter): New filter that interleaves Scheme frames with C
frames on the stack when the user asks for a backtrace.
* libguile/libguile-2.2-gdb.scm: Update to work with Guile 2.2 stacks.
Represent the VM stack as a SRFI-41 stream, which will work better
with the frame filter interface. Add support for getting the vm
frame's function name, if possible.
* lib/lightning.c: Remove the jit_regno_patch bitfield
register fields before actual emit, as it is only really
used before emit, otherwise, on special conditions it
may consider live registers as dead during code emit.
* lib/jit_x86-cpu.c, lib/jit_x86-sse.c, lib/jit_x86-x87.c:
Correct encoding of ldxr* stxr* in the x32 abi. If the
displacement register is negative, it would generate
a 64 bit instruction with a 32 bit unsigned displacement.
* check/ranger.tst, check/ranger.ok: New files, implementing
a test case for negative loads and stores. This is range.tst
converted to use registers instead of immediate offsets.
check/Makefile.am: Update for the new test case.
* module/ice-9/psyntax.scm (resolve-identifier): There is a case where a
syntax object can resolve to itself. Prevent an infinite loop in that
case by continuing to resolve by name.
* module/ice-9/psyntax-pp.scm: Regenerate.
* test-suite/tests/syncase.test ("infinite loop bug"): Add a test.
