* New function: rlink.Kaz Kylheku2023-09-231-0/+20
| | | | | | | | | | | | | | | This uses the linkat function to implement a variant of link which resolves the source object if it is a symlink. * configure: test for linkat. * sysif.c (link_wrap_common): New static function, used by both link_wrap and rlink_wrap.

* configure: fix: _TIME_BITS is tied to _FILE_OFFSET_BITSKaz Kylheku2023-08-121-29/+69
| | | | | | | | | | | | | | This problem was reported by Void Linux package maintainer adigitoleo. * configure: in glibc, _TIME_BITS and _FILE_OFFSET_BITS are not independent. You cannot make the former 64 if the latter isn't. I'm rewriting the test to check for these together, in all combinations. We succeed if we detect a combination that makes both time_t and off_t 64 bits. If we don't find such a combination then we at least enable 64 bit off_t alone or 64 bit time_t alone, if we encountered an option which does that.

* strings: take advantage of malloc_usable_sizeKaz Kylheku2022-10-061-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On platforms which have the malloc_usable_size function, we don't have to store the allocated size of an object; malloc provides us the allocated size (which may be larger than we requested). Here we take advantage of this for strings. And since we don't have to store the string allocated size any more, we use that field for something else: storing the hash code (for seed zero). This can speed up some hashing operations. * configure (have_malloc_usable_size): New variable. Configure test for have_malloc_usable size. We have to try several header files, too. We set the configure variable HAVE_MALLOC_USABLE_SIZE, and possibly HAVE_MALLOC_H or HAVE_MALLOC_NP_H. * lib.h (struct string): If HAVE_MALLOC_USABLE_SIZE is true, we define a member called hash insetad of alloc. Also, we change alloc to cnum. * lib.c: Include <malloc_np.h> if HAVE_MALLOC_NP_H is defined. (string_own, string, string_utf8, mkstring, mkustring, init_str, string_extend, string_finish, string_set_code, string_get_code, length_str, replace_str, chr_str_set): Fix code for both cases. On platforms with malloc_usable_size, we have the allocated size from malloc, so we don't have to retrieve it from the object or store it. Any operations which mutate the string must reset the hash field to zero; zero means "hash has not been calculated". * hash.c (equal_hash): Just retrive a string's hash value, if it is nonzero, otherwise calculate, cache it and return it. * gc.c (mark_obj): The alloc member of struct string is a machine integer now; no need to mark it.
* configure: bogus line preventing errors being shown.Kaz Kylheku2022-09-201-1/+0
| | | | | | | * configure: when the compiler is not found to be sane, we used to print the errors. But in a 2014 commit, the stray line "conftest && true" was left behind, whose termination status is false, and which thus causes an exit.
* configure: add missing "$@" to early reconfigure.Kaz Kylheku2022-09-191-1/+1
| | | | | | | | | * configure: the reconfigure script is generated twice; once before going through the configuration, with a notice indicating configuration did not complete, and then again after configuration. The first instance is missing the "$@" argument, preventing ./reconfigure being used with arguments after an interrupted configure run.
* android: pointer tagging countermeasure.Kaz Kylheku2022-09-171-0/+5
| | | | | | | | | | | | | | | | | | | | We strip Android's pointer tag from our heap pointer while we own it, then put it back at free time. * configure (android_target): New variable. Set this to y in the test where we detect Android. When setting CONFIG_NAN_BOXING, also set CONFIG_NAN_BOXING_STRIP_TAG if on Android. * gc.c (struct heap): New member, tag. (more): When tag stripping is enabled, clear the top 16 bits of the pointer coming from malloc, and keep those bits in heap->tag. This gets rid of Android's tag. (sweep): When releasing a heap block with free, we must put the tag back into the pointer, from heap->tag.

* configure: fix disabling NaN boxing on 32 bit.Kaz Kylheku2022-09-131-2/+3
| | | | | * configure: actually disable it, don't just print the warning. Warning should say 64 bits required, not 32.
* Implement NaN boxing.Kaz Kylheku2022-09-131-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On platforms with 64 bit pointers, and therefore 64-bit-wide TXR values, we can use a representation technique which allows double floating-point values to be unboxed. Fixnum integers are reduced from 62 bits to 50, and there is a little more complexity in the run-time type checking and dispatch which costs extra cycles. The support is currently off by default; it must be explicitly enabled with ./configure --nan-boxing. * lib.h (NUM_MAX, NUM_MIN, NUM_BIT): Define separately for NaN boxing. (TAG_FLNUM, TAG_WIDTH, NAN_TAG_BIT, NAN_TAG_MASK, TAG_BIGMASK, TAG_BIGSHIFT, NAN_FLNUM_DELTA): New preprocessor symbols. (enum type, type_t): The FLNUM enumeration constant moves to just after LIT, so that its value is the same as TAG_FLNUM. (struct flonum): Does not exist under NaN boxing. (union obj): No fl member under NaN boxing. (tag, is_ptr): Separately defined for NaN boxing. (is_flo): New function under NaN boxing. (tag_ex): New function. It's like tag, but identifies floating-point values as TAG_FLNUM. The tag function continues to map them to TAG_PTR, which is wrong under NaN boxing, but needed in order not to separately write tons of cases in the arith.c module. (type): Use tag_ex, so TAG_FLNUM is handled, if it exists. (auto_str, static_str, litptr, num_fast, chr, c_n, c_u): Different definition for NaN boxing. (c_ch, c_f): New function. (throw_mismatch): Attribute with NORETURN. (nao): Separate definition for NaN boxing. * lib.c (seq_kind_tab): Reorder initializer to follow enum reordering. (seq_iter_rewind): use c_n and c_ch functions, since type checking has been done in those cases. The self parameter is no longer needed. (iter_more): use c_ch on CHR object. (equal): Use c_f accessor to get double value rather than assuming there is a struct flonum representation. (stringp): Use tag_ex, otherwise a floating-point number is identified as TAG_PTR. (diff, isec, isecp): Don't pass removed self parameter to seq_iter_rewind. * arith.c (c_unum, c_dbl_num, c_dbl_unum, plus, minus, signum, gt, lt, ge, le, numeq, logand, logior, logxor, logxor_old, bit, bitset, tofloat, toint, width, c_num, c_fixnum): Extract floating-point value using c_f accessor. Handle CHR type separately from NUM because the storage representation is no longer identical; CHR values have a two bit tag over bits where NUM has ordinary value bits. NUM is tagged at the NaN level with the upper 14 bits being 0xFFFC. The remaining 50 bits are the value. (flo): Construct unboxed float under NaN boxing by taking image of double as a 64 bit value, and adding the delta offset, then casting to the val pointer type. (c_flo): Separate implementation for NaN boxing. (integerp, numberp): Use tag_ex. * buf.c (str_buf, buf_int): Separate CHR and NUM cases, like in numerous arith.c functions. * chksum.c (sha256_hash, md5_hash): Use c_ch accessor for CHR value. * hash.c (equal_hash, eql_hash): Handle CHR separately. Use c_f accessor for floating-point value. (eq_hash): Use tag_ex and handle TAG_FLNUM value under NaN boxing. Handle CHR separately from NUM. * ffi.c (ffi_float_put, ffi_double_put, carray_uint, carray_int): Handle CHR and NUM separately. * stream.c (formatv): Use c_f accessor. * configure: disable automatic selection of NaN boxing on 64 bit platforms, for now. Add test whether -Wno-strict-aliasing is supported by the compiler, performed only if NaN boxing is enabled. We need to disable this warning because it goes off on the code that reinterprets an integer as a double and vice versa.
* configure: config groundwork for NaN boxingKaz Kylheku2022-09-121-0/+28
| | | | | | | | | * configure (nan_boxing, nan_boxing_given): New variables. New help text for nan-boxing option. New test which sets nan-boxing if pointers are 64 bits, and also checks for nan-boxing wrongly being forced on a 32 bit target. Generate CONFIG_NAN_BOXING symbol in config.h.

If gzip is set, and gziplevel is nonzero then encode the level: gzopen will understand it. (open_file): If gzip mode is requested, then open the file using gzopen mode, a new function in gzio.c. The return a gzio stream based on the returned gzip file handle. However, if we are reading, and the gzip stream indicates that it's not decompressing anything, then we close it and open the file using an ordinary stream. (stream_init): Call gzio_init if HAVE_ZLIB is true. This is done here because the module is integrated with stream.c, and also so that lib.c doesn't have to know about HAVE_ZLIB and <zlib.h>.

* configure: bugfix in shell escaping codeKaz Kylheku2022-03-181-1/+1
| | | | | | | | | | | * configure: in the case when the argument contains single quotes, we try to identify the subcase that cannot use double quotes instead. That subcase is not correctly identified: it occurs when there are double quotes, dollar signs **or backslashes**. For instance the data '\ cannot be put into double quotes as "'\" on account of the backslash, which is an active character in double quotes. We also simplify the pattern by using a character class.
* configure: missing tab in shell escaping code.Kaz Kylheku2022-03-181-1/+1
