* module/system/vm/debug.scm (find-program-sources): If there is no
source location before the low-pc of the procedure we're grovelling
for, we were skipping the source loc info. Fix that.
* module/system/vm/program.scm (write-program): Get source info for
anonymous RTL functions.
(program-sources, program-sources-pre-retire): Provide program
counters relative to the beginning of the procedure.
* libguile/programs.c (scm_program_sources): Define as %program-sources,
and let Scheme export the program-sources proper.
(scm_program_source): Call out to Scheme.
* module/system/vm/program.scm: Convert to use match instead of pmatch.
Adapt existing callers.
(program-sources, program-source): New Scheme implementations of these
functions.
(program-sources-pre-retire): Add RTL program case.
* module/system/vm/debug.scm (<source>, source-pre-pc)
(source-post-pc, source-file, source-line, source-column)
(source-line-for-user): New data type for source location
information.
(find-source-for-addr, find-program-sources): New procedures to get
source location information for a particular address.
* module/system/vm/dwarf.scm (die-line-prog):
(line-prog-advance, line-prog-scan-to-pc): New public interfaces,
allowing clients to interpret the "statement programs" from
.debug_line DWARF sections.
(<meta>, elf->dwarf-context): Record the bounds of the .debug_line
section.
* module/web/client.scm (sanitize-request): Add a Content-Length
header if a body if given, even if the body is empty.
* module/web/server.scm (sanitize-response): Add a Content-Length
header if a body if given, even if the body is empty.
* module/srfi/srfi-9.scm: Add 2013 copyright date.
* test-suite/tests/srfi-9.test: Adapt to recent error reporting
improvements to procedures defined by 'define-tagged-inlinable'.
* module/ice-9/boot-9.scm (define-inlinable): Improve error reporting
when procedures defined using 'define-inlinable' are applied to the
wrong number of arguments.
* module/srfi/srfi-9.scm (define-tagged-inlinable): Improve error
reporting when procedures defined using 'define-tagged-inlinable' are
applied to the wrong number of arguments.
* module/language/tree-il/compile-cps.scm: New module implementing CPS
conversion of Tree-IL.
* module/Makefile.am:
* module/language/tree-il/spec.scm:
* module/language/cps/spec.scm: Integrate CPS in the build and language
system.
* module/scripts/disassemble.scm (disassemble): Update to work with
RTl (and only RTL, as that's the future).
* module/system/vm/debug.scm (for-each-elf-symbol): New public
interface.
(debug-context-from-image): New helper.
(find-debug-context): Use the helper.
* module/system/vm/disassembler.scm (disassemble-image): New public
interface.
* module/system/vm/assembler.scm (link-data): Give stringbufs the
"shared" flag already, so we don't attempt to set it at runtime. Give
.data sections the SHF_WRITE flag.
* module/system/base/compile.scm (compile-file): Pass #:to-disk? as an
option to indicate that the result will be being loaded from disk.
Perhaps a linker might want to page-align in that case.
* module/language/elisp/compile-tree-il.scm (process-options!): Accept
and ignore the #:to-file compiler option.
* module/language/tree-il/primitives.scm (maybe-simplify-to-eq): Wrap
within another lambda, binding the primitive name. If there are less
than two arguments, expand to constant #t. If there are more than two
arguments, convert into a conjunction of binary applications.
(expand-chained-comparisons): New procedure.
(*primitive-expand-table*): Add entries for (< <= = >= > eq?).
* module/ice-9/curried-definitions.scm (cdefine, cdefine*): Simplify,
and improve error reporting by making the patterns more strict.
(define-public): Fix bug in generated 'export' form.
* module/ice-9/boot-9.scm (module-add!): Check that the symbol argument
is actually a symbol.
(define-public): Expand into 'define' in such a way that curried
definitions will immediately fail.
* module/Makefile.am: match.go depends on match.upstream.scm.
* module/ice-9/match.scm (error): Accept any number of arguments.
* module/ice-9/match.upstream.scm (match-next): Call 'error' in non-tail
context, and include the value that failed to match in the call.
* module/language/tree-il/primitives.scm (define-primitive-expander):
Use 'match-lambda*' instead of 'case-lambda' for pattern matching.
(*primitive-expand-table*): In primitive expanders for '+', '*', '-',
'/', 'logior', and 'logand', assume conventional left-to-right
associativity.
* libguile/instructions.c (FOR_EACH_INSTRUCTION_WORD_TYPE): Allow for
five-word instructions, and for new instruction word types.
* libguile/vm-engine.c (RETURN_ONE_VALUE): Instead of returning the
value in the fixed part of the call frame, return it in the same place
multiple-value returns go: from slot 1.
(BR_ARITHMETIC): Allow arithmetic tests to be negated.
(rtl_vm_engine): Change calling convention to use the same location
for single and multiple-value returns. Renumber all instructions.
(halt, halt/values): Fold into a single instruction (halt).
(call): Take the location of the procedure instead of the location of
the call frame. Also take the number of args, and reset the sp before
jumping to the procedure, so as to indicate the number of arguments.
(call/values): Remove, as the new calling convention has RA == MVRA.
(tail-call): Require the procedure to be shuffled down already, and
take "nlocals" as an arg instead of "nargs".
(receive, receive-values): New instructions, for receiving returned
values from calls.
(return-values): Rename from return/values. Remove "values".
(alloc-frame): Rename from reserve-locals.
(reset-frame): New instruction.
(drop-locals): Remove.
(br-if-=, br-if-<, br-if-<=): Allow these instructions to be
negatable.
(br-if->, br-if->=): Remove. Probably a bad idea, given NaN.
(box-ref): Don't bother trying to do a reverse lookup -- the
toplevel-box, module-box, and resolve instructions should handle
that.
(resolve): Add arg to check that the variable is bound.
(toplevel-box, module-box): New instructions, replacing toplevel-ref,
toplevel-set, module-ref, and module-set.
* libguile/vm.c (rtl_boot_continuation_code, rtl_values_code): Adapt to
instruction set changes.
* module/Makefile.am: Make the assembler and disassembler dependent on
vm-operations.h.
* module/system/vm/assembler.scm:
* module/system/vm/disassembler.scm: Adapt to instruction changes and
new instruction word kinds.
* test-suite/tests/rtl.test: Adapt to instruction set changes.
* module/language/tree-il/peval.scm (peval): Remove abort optimization;
the CPS compiler will do much better here, and it is complicating
things in the meantime.
