* stat: support high resolution time stamps.Kaz Kylheku2019-10-291-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | * configure (have_sys_stat): New variable. Set to y when our test detects <sys/stat.h>. New test added for the presence of high resolution time stamps in struct stat. If we have these, we #define HAVE_STAT_NSEC 1 in config.h. * share/txr/stdlib/path-test.tl (path-newer): Compare nanosecond parts of the modification time if the seconds are equal, improving the resolution of the test. * sysif.c (atime_nsec_s, mtime_nsec_s, ctime_nsec_s): New symbol variables. (stat_to_struct): If nanosecond resolution is available, set the new nanosecond slots from the three tv_nsec fields in struct stat. Otherwise, set the new slots to zero. (sysif_init): Initialize the new symbol variables. Add the three new slots to the stat struct. * sysif.c (atime_nsec_s, mtime_nsec_s, ctime_nsec_s): Declared. * txr.1: Documented new atime-nsec, mtime-nsec and ctime-nsec slots of stat structure. Added note to path-newer mentioning high resolution support.

* configure: memalign fixes.Kaz Kylheku2019-10-251-1/+23
| | | | | | | | | | | | | | | | | | | | | This fixes build problems on Mac OS and Solaris due to the introduction of the use of memalign. * configure: After detecting that __EXTENSIONS__ is required on Solaris and adding that to lang_flags, we must call gen_config_make so that it becomes available to subsequent configure tests. On Solaris, memalign is just in <stdlib.h>, so let's test for that first, then test for a memalign in <malloc.h>, and in that case add HAVE_MALLOC_H into config.h. Also, fixing two bugs here. Firstly, the memalign test used inverted logic, causing HAVE_MEMALIGN to be defined on platforms that don't have it. Secondly, the dummy while loop that is just supposed to be a control structure for forward breaks turned infinite due to a missing break at the bottom. * lib.c: if HAVE_MALLOC_H is defined and nonzero, then include <malloc.h>.
* gc: align objects more strictly.Kaz Kylheku2019-09-121-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In this commit, we ensure that objects in the heap are aligned to at east eight byte boundaries (the minimum alignment from most malloc implementations on 32 and 64 bit systems). If possible, we align objects to a multiple of their size, sizeof (obj_t), which is 16 bytes on 32 bit platforms and 32 bytes on 64 bit platforms. We do this by making the object array the first field of the heap structure, and by allocating it with an aligned allocator function, if possible. * configure: detect memory alignment function: either memalign (preferred) or else posix_memalign (ugly duckling). We conditionally add either HAVE_MEMALIGN or HAVE_POSIX_MEMALIGN into config.h. * gc.c (OBJ_ALIGN): New macro. (struct heap, heap_t): Put the block member first, so objects are aligned with the containing heap. (in_heap): If the pointer is not aligned to a multiple of OBJ_ALIGN, it can't be a heap object; return zero. If allocations of the heap are aligned, then we don't need the additional alignment check in the loop body; if the pointer lands in the array, then the earlier OBJ_ALIGN check assures us it must be aligned. If we have only malloc alignment, we must do the check; the pointer could be to an address divisible by 8 which is in the middle of an obj_t. * lib.c: If HAVE_MEMALIGN is true, then include <malloc.h> so we have it declared. (memalign): If HAVE_POSIX_MEMALIGN is true, this static function is defined; it's compatible with the Glibc memalign. If HAVE_MEMALIGN and HAVE_POSIX_MEMALIGN are false, then memalign is defined as a malloc wrapper which doesn't align. (chk_malloc_gc_more): Use memalign instead of malloc. If aligned allocation is available, this will cause the heap to be aligned to a multiple of the object size.

| | | | | | | | | | | | | | | | | * configure: In several config tests, test HAVE_SUPERLONG_T, HAVE_LONGLONG_T and HAVE_SYS_WAIT with #if. * lib.c: Test HAVE_GETENVIRONMENTSTRINGS with #if. * lib.h: Test HAVE_DOUBLE_INTPTR_T with #if. * mpi/mpi.c: Likewise. * mpi/mpi.h: Likewise. * socket.c: Test HAVE_GETADDRINFO with #if in three places. * stream.c: Test HAVE_SYS_WAIT and HAVE_SOCKETS with #if.

* bugfix: c_num won't convert most negative value.Kaz Kylheku2019-05-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | This bug causes a problem particularly in FFI. THe conversion of an integer to the FFI int type begins by conversion via c_num to the cnum type, which is at least as wide as int. Alas, the INT_MIN value (e.g. #x-80000000 on 32 bits) will not convert! Fixing this has a ripple effect. We alter the INT_PTR_MIN constant to include this value. This causes the derived NUM_MIN to also include the extra negative value, extending the fixnum range by one value. Everything seems to be okay. * configure: Decrease value of INT_PTR_MIN and DOUBLE_INTPTR_MIN constants by one to include the most negative two's complement value. * ffi.c (make_ffi_type_enum): We must not subtract 1 from INT_PTR_MIN here any more. * mpi.c (mp_in_range): If the bignum is negative, then extend the range check by one value, so that we don't reject the most negative two's complement value.

* build: allow $(pwd)/configure to work.Kaz Kylheku2019-04-291-1/+12
| | | | | | | | | | | | | | | | | | | | | When the build is being done in the source directory, allow the configure script to be executed via path names other than just ./configure, such as an absolute path. Some distros use this. * configure (build_in_srcdir): New variable. (inode): New function. Rather than checking whether "$source_dir" is ".", we test whether they are the same inode. If they are the same, we now also set the build_in_srcdir variable in addition to generating the usual warning. (gen_config_make): Propagate the build_in_srcdir into config.make. * Makefile: use the build_in_srcdir variable from config.make to determine whether we are building in the source directory, rather than relying on top_srcdir being blank.

* float: turn out-of-range calculations into exceptions.Kaz Kylheku2019-03-121-0/+27
| | | | | | | | | | | | | | | On platforms that have the C99 fpclassify, we can use it to banish infinity and NaN representations. If such a thing arises, we throw an exception rather than producing an object that prints as #<bad-float>. * configure: add detection for fpclassify. * lib.c (bad_float): New inline function and macro. (flo): If the argument is other than zero, a normal value or a subnormal, then throw an exception. We thereby refuse to admit such objects into our numeric object system.

* configure: problems with 128 bit integer detection.Kaz Kylheku2019-01-261-10/+11
| | | | | | | | | | | * configure: we can't assume that we can just edit "int" to "uint" in forming the superulong_t type. Let's consolidate the detection of the signed and unsigned superlong. Only if both are available, then emit material into config.h, along with a single constant: HAVE_SUPERLONG_T. * mpi/mpi-types.h: Don't refer to removed HAVE_USUPERLONG_T. Change superulong_t to usuperlong_t.
* Extend infrastructure for double_intptr_t.Kaz Kylheku2019-01-251-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We support an unsigned version of the type, and add functions for converting between Lisp values and both types. * arith.c (bignum_dbl_uipt): New function, unsigned companion to existing bignum_dbl_ipt. (c_dbl_num, c_dbl_unum): New functions. * arith.h (bignum_dbl_uipt, c_dbl_num, c_dbl_unum): Declared. * configure (superulong_t, SIZEOF_DOUBLE_INTPTR, DOUBLE_INTPTR_MAX, DOUBLE_INTPTR_MIN, DOUBLE_UINTPTR_MAX, double_uintptr_t): New definitions going into config.h. * lib.h (dbl_cnum, dbl_ucnum): New typedefs: double-sized analogs of cnum and ucnum. * mpi/mpi.c (mp_set_double_uintptr, mp_get_double_uintptr, mp_get_double_intptr): New functions. (s_mp_in_big_range): New static function. (mp_in_double_intptr_range, mp_in_double_uintptr_range): New functions. * mpi/mpi.h (mp_set_double_uintptr, mp_get_double_intptr, mp_get_double_uintptr, mp_in_double_intptr_range, mp_in_double_uintptr_range): Declared.
* Fix some instances of 4 bytes = 32 bits assumption.Kaz Kylheku2019-01-231-4/+10
| | | | | | | | | | | | | | | | | * hash.c (equal_hash, eql_hash, cobj_eq_hash_op, hash_hash_op): Multiply object size by CHAR_BIT and switch on number of bits, rather than bytes. * sysif.c (off_t_num): Likewise. * arith.c, ffi.c, itypes.c, rand.c: In numerous #if directive, fix size tests from bytes to bits. * configure: in the test that detects integer types, and in the test for enabling large file offsets, detect one more variable from the system: the value of CHAR_BIT. This turns into SIZEOF_BYTE. We use that value instead of a hard-coded 8.

* configure: improvements related to int_ptr_t.Kaz Kylheku2019-01-181-9/+3
| | | | | | | | | | | | | | * configure: We remove the uintptr variable and do not generate the HAVE_UINTPTR_T constant in config.h. This is always 1, and not actually tested anywhere. In situations when uintptr is not established, intptr is also not established and the configure script fails. We simply assume that for whatever type we detect as inptr_t, we can derive the unsigned type. (INT_PTR_MAX): We define this a bit differently; instead of interpolating into the expression the underlying C type, we use the int_ptr_t typedef that the previous lines of config.h establish. (UINT_PTR_MAX): New constant introduced in config.h.
