Fixes <http://bugs.gnu.org/18299>.
Reported by Frank Terbeck <ft@bewatermyfriend.org>.
* module/language/tree-il/analyze.scm (format-string-argument-count):
Add case for ~p.
* test-suite/tests/tree-il.test ("warnings")["format"]("~p", "~p, too
few arguments", "~:p", "~:@p, too many arguments", "~:@p, too few
arguments"): New tests.
* module/language/cps/types.scm (&all-types): Represent true and false
as separate bits, so that #f can be removed from types on true
branches. Adapt all users.
* module/language/cps/type-fold.scm (&scalar-types):
(fold-and-reduce): Adapt to boolean type representation change.
* lib/jit_aarch64-cpu.c, lib/jit_aarch64-fpu.c,
lib/jit_arm-cpu.c, lib/jit_arm-vfp.c,
lib/jit_hppa-cpu.c, lib/jit_hppa-fpu.c,
lib/jit_ia64-cpu.c, lib/jit_ia64-fpu.c,
lib/jit_mips-cpu.c, lib/jit_mips-fpu.c,
lib/jit_ppc-cpu.c, lib/jit_ppc-fpu.c,
lib/jit_s390x-cpu.c, lib/jit_s390x-fpu.c,
lib/jit_s390x.c, lib/jit_sparc-cpu.c,
lib/jit_x86-cpu.c, lib/jit_x86-sse.c,
lib/jit_x86-x87.c: Review generation of all branch
instructions and always adds the jit_class_nospill
bitfield for temporary registers that cannot be spilled
because the reload would be after a conditional jump; the
patch only adds an extra assertion. These conditions do
not happen on documented lightning usage, but can happen
if one uses the not exported jit_get_reg and jit_unget_reg
calls and cause enough register starvation.
* lib/jit_alpha.c: Correct wrong bitmask of most argument
float register arguments, that were being set as callee
save instead of argument registers class.
* lib/jit_arm-sz.c: Regenerate table of known maximum
instruction sizes for the software float fallback,
that implements "virtual" float registers in the stack
and operations as calls to libgcc.
* size.c: Correct typo in the generated jit_arm-sz.c file.
Based on a patch by Eli Zaretskii <eliz@gnu.org>.
* libguile/i18n.c (copy_string_or_null): New static function.
(scm_nl_langinfo): Use 'copy_string_or_null' to copy the result from
'nl_langinfo' and 'nl_langinfo_l' before the next call and before
releasing the locale mutex.
* test-suite/tests/coding.test (with-temp-file): Instead of
hard-coding "/tmp" as the temporary directory, use $TMPDIR or
$TEMP from the environment, and fall back on "/tmp" if none of
those 2 is defined.
* doc/ref/api-utility.texi (Object Properties)[make-object-property]:
Clarify that object-properties cannot be reliably applied to numbers.
Signed-off-by: David Kastrup <dak@gnu.org>
* include/lightning/jit_alpha.h, lib/jit_alpha-cpu.c,
lib/jit_alpha-fpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c:
New files implementing a lightning Alpha port. Thanks
to Trent Nelson and snakebit.net staff for providing access
to an Alpha system.
* check/float.tst, check/lightning.c, configure.ac,
include/lightning.h, include/lightning/Makefile.am,
include/lightning/jit_private.h, lib/Makefile.am,
lib/jit_disasm.c, lib/jit_size.c, lib/lightning.c:
Minor changes to adapt for the new Alpha port.
* lib/lightning.c: Always mark JIT_RET and JIT_FRET as
live in a function epilog. This is required because
on some ports a complex sequence, allocating one or more
registers, may be required to jump from a ret* to the
epilog, and the lightning api does not have annotations
to know if a function returns a value, or the type of
the return value.
* module/ice-9/boot-9.scm (add-to-load-path): Remove argument from
%load-path (if it exists) before pushing. This also means that the
`elt' will always be at the front of %load-path.
* lib/jit_memory.c: Do not call free on NULL pointers.
* include/lightning/jit_private.h, lib/jit_note.c,
lib/lightning.c: Add a wrapper to memcpy and memmove
to not actually call those functions with a zero size
argument, and likely also a null src or dst.
* include/lightning/jit_private.h, lib/jit_disasm.c,
lib/lightning.c: Remove the global jit_progname variable.
It was being only used in jit_init_debug, that is called
from init_jit, so, just pass an argument.
* module/language/cps/simplify.scm (redominate): Add micropass to
rewrite the scope tree to reflect the dominator tree. Will enable
better eta reduction.
* module/language/cps/slot-allocation.scm (allocate-slots): For
continuations of $call, $callk, and $values with multiple
predecessors, recalculate the set of live slots. Fixes miscompilation
of ice-9/futures.scm:process-future!, broken since the previous patch,
now that $kreceive continuations can have multiple predecessors.
* module/language/cps/renumber.scm (compute-new-labels-and-vars):
(compute-tail-path-lengths, sort-conts): Arrange to visit successors
in such a way that if branches are unsorted, the longest path length
will appear first. This keeps loop bodies together.
Suggested by Dale P. Smith.
* module/system/base/target.scm (cpu-endianness): Add cases for
"arm.*eb", "^aarch64.*be", and "aarch64". Change "arm" case to
"arm.*".
(triplet-pointer-size): Allow underscore as in 'aarch64_be'.
* test-suite/tests/asm-to-bytecode.test ("cross-compilation")["armeb-unknown-linux-gnu",
"aarch64-linux-gnu", "aarch64_be-linux-gnu"]: New tests.
* libguile/bitvectors.c (scm_bit_count_star): Fix typo introduced in
2005 refactor (!) in which the second arg was erroneously taken from
the first arg.
* test-suite/tests/bitvectors.test: Add test.
* doc/ref/api-compound.texi: Fix doc example for u32vector selector.
Reported by Sylvain Beucler <beuc@beuc.net>.
* configure.ac: Check for 'pthread_cancel'.
* libguile/threads.c (scm_cancel_thread): Conditionalize on
!SCM_USE_PTHREAD_THREADS || defined HAVE_PTHREAD_CANCEL.
* test-suite/tests/threads.test (require-cancel-thread): New procedure.
("timed joining fails if timeout exceeded", "join-thread returns
timeoutval on timeout", "cancel succeeds", "handler result passed to
join", "can cancel self"): Use it.
Reported by Sylvain Beucler <beuc@beuc.net>.
* module/system/base/target.scm (cpu-endianness): Add case where CPU is
"arm".
* test-suite/tests/asm-to-bytecode.test ("cross-compilation")["arm-unknown-linux-androideabi"]:
New test.
* module/language/cps/type-fold.scm (fold-and-reduce): Don't require
types to check out; it could be that the reduced expression can
exhibit the same type-check effects. Reduce for all continuations,
even $kreceive. Pass dfg to reducer.
(mul): Check types.
(logbit?): New reducer.
* libguile/load.c (scm_i_mirror_backslashes): New function.
(scm_init_load_path): Call it to produce MS-Windows file names
with forward slashes.
(FILE_NAME_SEPARATOR_STRING): Define as "/" on all platforms.
* libguile/load.h (scm_i_mirror_backslashes): Add prototype.
* libguile/init.c (scm_boot_guile): Call scm_i_mirror_backslashes
on argv[0].
* libguile/filesys.c (scm_getcwd): Call scm_i_mirror_backslashes
on the directory name returned by getcwd.
* test-suite/tests/ports.test ("file name separators"): New test.
