* module/language/cps/dfg.scm (variable-free-in?): Rename from
variable-used-in?, to match CWCC language.
(variable-bound-in?): New interface.
* module/language/cps/contification.scm (contify): Adapt caller. Add
more comments.
* libguile/numbers.c (left_shift_exact_integer): Fix edge case where
N is -1 and count is SCM_I_FIXNUM_BIT-1 to return the most negative
fixnum. Previously this result was returned as a bignum.
* test-suite/tests/numbers.test (ash): Add tests.
* 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.
* libguile/numbers.c (scm_ash): Fix (ash -1 SCM_I_FIXNUM_BIT-1) to
return a fixnum instead of a bignum.
* test-suite/tests/numbers.test (ash): Add tests.
* test-suite/tests/dwarf.test: New test, testing that source location
information survives the round-trip through the compiler, back out to
the (system vm debug) interfaces.
* 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.
* libguile/ports.c (scm_ungetc_unlocked): Inline the conversion from
codepoint to bytes for UTF-8 and latin-1 ports. Speeds up a
numbers-reading test case by 100% (!).
* 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.
* libguile/vm-engine.c (return-values): Remove NVALUES operand.
Don't reset the frame.
* test-suite/tests/rtl.test ("cached-toplevel-set!"): Adapt to the fact
that 'return-values' has no operand now, and that 'reset-frame' must
be done first.
