* module/rnrs/exceptions.scm (&guile): New condition type.
(guile-condition-converters): New variable.
(convert-guile-condition, default-guile-condition-converter,
set-guile-condition-converter!, guile-common-conditions,
guile-lexical-violation-converter, guile-syntax-violation-converter,
guile-assertion-violation-converter, guile-system-error-converter,
guile-undefined-violation-converter, guile-error-converter,
guile-implementation-restriction-converter): New procedures.
(with-exception-handler): Catch all exceptions, not just R6RS
exceptions. Convert native Guile exceptions to R6RS conditions,
preserving the original Guile exception information in the &guile
condition object.
(raise): If the condition includes a &guile condition, use 'throw' to
throw the original native guile exception instead of raising an R6RS
exception.
* test-suite/tests/r6rs-exceptions.test ("guile condition conversions"):
Add tests.
* test-suite/tests/cross-compilation.test: Rename from asm-to-bytecode,
and remove the bits testing assembly->bytecode but keep the
cross-compilation things.
* test-suite/Makefile.am: Adapt.
* module/ice-9/session.scm (procedure-arguments): Add an rtl-program?
case.
* module/system/vm/debug.scm (arity-arguments-alist): Use the order that
session.test expects.
* test-suite/tests/session.test ("procedure-arguments"): Adapt tests
with keywords for the new starting-with-the-procedure numbering of
locals.
* test-suite/tests/coverage.test ("instrumented-source-files"): Adapt to
new expectation that all files loaded on the system will be present in
the source information.
* test-suite/tests/coverage.test ("procedure-execution-count"): Adapt
test to new behavior of procedure-execution-count of an unseen
procedure: zero, not false.
* test-suite/tests/coverage.test ("line-execution-counts"): Fix test for
even/odd? in letrec. The test profiles the execution of even?, not
the letrec, so the last line is in fact not reached.
* libguile/uniform.h:
* libguile/uniform.c (scm_uniform_vector_element_type_code): New
interface, returns a type code as an integer.
* module/system/vm/assembler.scm (<uniform-vector-backing-store>)
(simple-vector?, uniform-array?, statically-allocatable?)
(intern-constant, link-data, link-constants): Support uniform arrays,
and punt on vectors aren't contiguous from 0. Support for general
arrays will come later.
* test-suite/tests/rtl.test ("load-constant"): Add tests.
* libguile/foreign.c: Convert to using RTL stubs. Because RTL code has
different GC characteristics than objcode -- it's mostly assumed that
RTL code will never go away -- we go ahead and pre-generate code for
100 arguments. This is actually less memory than the stack VM code,
and doesn't require any relocations at load-time: bonus! We'll cross
the >=100 args bridge if we ever come to it.
(get_foreign_stub_code) New function.
(scm_i_foreign_arity): New helper, like scm_i_primitive_arity.
(cif_to_procedure): Rework to make RTL programs.
* libguile/foreign.h: Declare scm_pointer_to_scm and
scm_scm_to_pointer. Declare new internal helpers.
* libguile/gsubr.c (create_subr): Refactor to set the flags when the
object is allocated.
* libguile/instructions.h: Define SCM_PACK_RTL_12_12.
* libguile/programs.c (scm_i_rtl_program_minimum_arity): Dispatch to
scm_i_foreign_arity if the procedure has the FOREIGN flag.
* libguile/programs.h (SCM_F_PROGRAM_IS_FOREIGN)
(SCM_PROGRAM_IS_FOREIGN): New interfaces.
* test-suite/tests/foreign.test ("procedure->pointer"): Add a test for
foreign arities.
* libguile/gsubr.c: Define RTL stubs instead of stack VM stubs.
(SUBR_STUB_CODE, get_subr_stub_code): Adapt to return a uint32_t*
pointer instead of a SCM value.
(create_subr): Create RTL procedures instead of stack VM procedures.
For RTL procedures, the function pointer, name, and generic address
pointer go inline to the procedure, as free variables.
(scm_i_primitive_arity, scm_i_primitive_call_ip): New helpers.
(scm_c_make_gsubr, scm_c_define_gsubr, scm_c_make_gsubr_with_generic)
(scm_c_define_gsubr_with_generic): Adapt to create_gsubr being renamed
to create_subr.
Remove gsubr test code.
* libguile/gsubr.h (SCM_PRIMITIVE_P, SCM_PRIMITIVE_GENERIC_P): Only RTL
programs can be primitives now.
(SCM_SUBRF, SCM_SUBR_NAME, SCM_SUBR_GENERIC): These fields are now in
the RTL free variables, not the object table.
* libguile/programs.c (scm_i_rtl_program_name):
(scm_i_rtl_program_documentation):
(scm_i_rtl_program_properties):
(scm_i_rtl_program_minimum_arity): Implement these appropriately for
primitives, which lack debugging information.
(scm_primitive_p, scm_primitive_call_ip): New helpers.
* libguile/snarf.h: Remove static allocation for subrs. Since there is
nothing to allocate besides the program itself, which needs runtime
relocation, static allocation is not a win.
* system/vm/program.scm: Fix up various arity-related things for
primitives, which don't use ELF arity info.
* test-suite/tests/eval.test ("stack involving a primitive"): Add an
XFAIL until we get just one VM.
* module/language/tree-il/peval.scm (peval): Fix a bug whereby inlined
function applications with default argument initializers were putting
the initializers in the wrong scope.
* test-suite/tests/peval.test ("partial evaluation"): Add a test.
* test-suite/tests/rtl-compilation.test ("contification"): Add
contification test where non-recursive call is not in tail position
relative to the letrec.
* 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.
* 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/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'.
* 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.
Fixes <http://bugs.gnu.org/15100>.
Reported by Göran Weinholt <goran@weinholt.se>.
* libguile/bytevectors.c (INTEGERS_TO_LIST): Enforce the R6RS
requirement that SIZE divides the bytevector length.
* test-suite/tests/bytevectors.test: Add test. Remove tests that
assumes that this "divides" check is not enforced.
Partially fixes <http://bugs.gnu.org/15100>.
Reported by Göran Weinholt <goran@weinholt.se>.
* libguile/bytevectors.c (INTEGERS_TO_LIST): Make sure SIZE isn't 0.
Allow SIZE to be greater than the bytevector length, for consistency
with allowing extra bytes at the end when the bytevector length is
non-zero. Use scm_from_size_t instead of scm_from_uint.
* test-suite/tests/bytevectors.test: Add tests. Remove a test that
checks for an exception when SIZE is greater than the bytevector
length.
* test-suite/tests/peval.test ("partial evaluation"): Adapt tests to the
fact that arithmetic operators are now expanded into binary ops with
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.
* libguile/numbers.c (scm_numerator, scm_denominator): Handle signed
zeroes and infinities in accordance with the corresponding R6RS flonum
procedures.
* module/rnrs/arithmetic/flonums.scm (flnumerator, fldenominator):
Remove special handling of infinities.
* test-suite/tests/numbers.test (numerator, denominator): Add tests.
Convert existing tests to use 'pass-if-equal'.
* test-suite/tests/r6rs-arithmetic-flonums.test (flnumerator): Fix
broken test of (flnumerator -0.0).
* libguile/strports.c (scm_mkstrport): Use UTF-8; ignore
%default-port-encoding. Rename 'str_len' and 'c_pos' to
'num_bytes' and 'c_byte_pos'. Interpret 'pos' argument
as a character index instead of a byte index.
* module/ice-9/boot-9.scm (%cond-expand-features): Add srfi-6 to the
list of core features.
* module/srfi/srfi-6.scm (open-input-string, open-output-string): Simply
re-export these, since the core versions are now compliant.
* doc/ref/api-io.texi (String Ports): Remove text that describes
non-compliant behavior of string ports with regard to encoding.
* doc/ref/srfi-modules.texi (SRFI-0): Add srfi-6 to the list of
core features.
(SRFI-6): Remove text that mentions non-compliant behavior of
core string ports.
* module/ice-9/format.scm (format):
* module/ice-9/pretty-print.scm (truncated-print):
* module/rnrs/io/ports.scm (open-string-input-port,
open-string-output-port):
* test-suite/test-suite/lib.scm (format-test-name):
* test-suite/tests/chars.test ("combining accent is pretty-printed",
"combining X is pretty-printed"):
* test-suite/tests/ecmascript.test (eread, eread/1):
* test-suite/tests/rdelim.test:
* test-suite/tests/reader.test (read-string):
* test-suite/tests/regexp.test:
* test-suite/tests/srfi-105.test (read-string): Don't set
%default-port-encoding before creating string ports.
* benchmark-suite/benchmarks/ports.bm (%latin1-port): Use
'set-port-encoding!' to set the string port encoding.
(%utf8/ascii-port, %utf8/wide-port, "rdelim"): Don't set
%default-port-encoding before creating string ports.
* test-suite/tests/r6rs-ports.test ("lookahead-u8 non-ASCII"): Don't set
%default-port-encoding before creating string ports.
("put-bytevector with UTF-16 string port", "put-bytevector with
wrong-encoding string port"): Use 'set-port-encoding!' to set the
string port encoding.
* test-suite/tests/print.test (tprint): Use 'set-port-encoding!' to set
the string port encoding.
("truncated-print"): Use 'pass-if-equal'.
* test-suite/tests/ports.test ("encoding failure leads to exception",
"%default-port-encoding is honored", "peek-char [latin-1]", "peek-char
[utf-8]", "peek-char [utf-16]"): Remove tests.
("%default-port-encoding is ignored", "peek-char"): Add tests.
("suitable encoding [latin-1]", "suitable encoding [latin-3]",
"wrong encoding, error", "wrong encoding, substitute",
"wrong encoding, escape"): Use 'set-port-encoding!' to set the
string port encoding.
("%default-port-encoding, wrong encoding"): Rewrite to use
a file port instead of a string port.
* libguile/vm-engine.c (push_frame, call): Separate out push_frame from
call, and expect the caller to arrange the proc and arguments.
* test-suite/tests/rtl.test ("call"): Update tests.
