* * configure: Added check to detect POSIX sleep function.Kaz Kylheku2013-11-271-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * eval.c (eval_init): Register new open_tail function as intrinsic. * match.c (complex_snarf, complex_stream): Update calls to make_stdio_stream and make_pipe_stream to take fewer arguments. (match_files): Support a stream object as a data source specification in place of a string. * parser.l (parse_reset): Update call to make_stdio_stream to take fewer arguments. * stream.c: Inclusion of <unistd.h> made properly conditional. (struct stdio_handle): pid member defined as pid_t only if we have fork functionality, otherwise defined as int. (tail_get_line, tail_get_char, tail_get_byte): New static functions. (tail_ops): New static structure. (make_stdio_stream_common): New static structure. (make_stdio_stream, make_pipe_stream): These functions lose the input and output parameters, which ended up never used. Reimplemented in terms of new common function. (make_tail_stream): New function. (make_pipevp_stream): Reimplemented in terms of new common function. (open_file, open_command): Simplified by removal of useless local variables and their computation, which used to be extra arguments to make_stdio_stream and make_pipe_stream. (open_tail): New function. (stream_init): Calls to make_stdio_stream updated. * stream.h (make_stdio_stream, make_pipe_stream): Declarations updated. (make_tail_stream, open_tail): Declared. * txr.c (txr_main): Calls to make_stdio_stream updated.

* * Makefile (clean): depends on conftest.cleanKaz Kylheku2013-10-281-2/+1
| | | | | | | | (conftest.clean): New target. * configure: Use "make conftest.clean" to clean up conftest stuff. Note that there was a bug here: brace expansion was used, but the shell is /bin/sh, so conftest.err wasn't being removed.
* Ouch! Turns out the code base has numerous unintendedKaz Kylheku2013-10-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | deviations from C90, like mixed declations and statements. GCC doesn't diagnose these without the --pedantic flag. * configure: GCC's --ansi flag should be spelled -ansi. * lib.c (split_str, obj_print): Reorder declaration before statements. (make_sym): Fix similar problem by eliminating a statement. (funcall1, funcall2, funcall3, funcall4): Use assignment to initialize local array with non-constant elements. This is actually good for performance because we only initialize those parts of the array that we use. * lib.h (struct func): Change functype member to unsigned, since enum-typed bitfields are a GCC extension. * match.c (ml_all, mf_all): Use assignments to initialize local struct with non-constants. (do_txeval, v_collect): Slightly revise unwinding macrology with help of new macros to avoid mixing declarations and statements. (spec_bind): Removed spurious semicolon from macro expansion. (v_gather): Reorder two lines to avoid mixed decls and statements. (match_filter): Move declaration of ret a few lines up, ahead of statements. * unwind.c (uw_pop_until): New function. * unwind.h (uw_pop_until): Declared. (uw_mark_frame, uw_fast_return): New macros.
* * configure: Change to header block comment generated in config.hKaz Kylheku2013-10-231-1/+1

* Fixes for configuring and building in a separate directory.Kaz Kylheku2012-04-201-6/+5
| | | | | | | | | | * configure: MPI is now extracted and patched in the build directory, not in the source directory. * Makefile (CFLAGS): Refer to mpi headers relative to current directory, not $(top_srcdir). (repatch): Run MPI repatching steps in correct directory. (clean): Remove extracted MPI from build directory.

* * configure: Restructuring configure script to be able to detectKaz Kylheku2012-04-131-51/+65
| | | | | | | | | | nonexistent options. Variable default values are established first, which simplifies the syntax. The scanning loop detects attempts to create configuration variables that do not exist. The var_given convention is folded into the parsing. (If var exists, and var_given exists, and the user specifies var, then var_given is set to y to indicate that the value came from the user.)
* More NetBSD porting.Kaz Kylheku2012-04-101-1/+27
| | | | | | | | | | | | | | | | | | * Makefile (EXTRA_FLAGS): Handy new variable for additional ad-hoc CFLAGS. Needed by a new test in configure. * configure: Check for annoying warnings about char being used as an array subscript when calling the macros from <ctype.h>. If this occurs, suppress it by #undef-ing the macros. (lang_flags): Switching fromm _XOPEN_SOURCE to _XOPEN_SOURCE=2 because this is needed on NetBSD to obtain declarations of popen and pclose. * stream.c (pipe_close): If we don't have the WIFCONTINUED macro, then define it to expand to zero. It's absent on NetBSD and they already seem to have a hack for this because there is a warning about the function not being defined, but then the program links anyway. Let's do it properly and not rely on their hack.
* * configure: Switch from _POSIX_C_SOURCE=2 to _XOPEN_SOURCE.Kaz Kylheku2012-04-101-1/+1
| | | | | | | | We will be relying on the gettimeofday function which only came into POSIX in 2001, but was in Unix long before then. * HACKING: Replace notes about -D_POSIX_C_SOURCE which are not true any more.
* * Makefile (conftest.ccver): New phony target.Kaz Kylheku2012-04-101-20/+31
| | | | | | | * configure: The test for non-working 128 bit integers in the gcc used by NetBSD 5.1 is not good enough to catch the bug. Adding a test which will assume that gcc 4.3.x and lesser does not have working 128 bit types.
* NetBSD port.Kaz Kylheku2012-04-091-69/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | * arith.c (bignum_dbl_ipt): Added missing #if HAVE_DOUBLE_INTPTR_T around function * configure: NetBSD's shell is too pathetic to expand "$@" properly when there are no positional arguments, so I applied the ${@+"$@"} trick. (make): New variable. GNU make might be known only as gmake, so we now detect the command for our own use within the configure script and also for giving the user advice on what command to use for building. Put in a fix so that the attempt to run $make --version does not bail the script under "set -e" if that command terminates unsuccessfully. The check for clashing names has been moved earlier, so that the renaming #define's appear early in config.h (so config.h itself can rely on the renames). The identifier longlong_t has been added to the potential clash list. NetBSD exposes this identifier in spite of -D_POSIX_SOURCE=2, and it clashes with our longlong_t. The tests for integers wider than long long has been modified to actually compile a multiplication of two long-long-s into the wider precision. On the NetBSD system, with gcc 4.1.3, I found that the __int128 type is there, but doesn't actually work; compilation of arith.c bails with an internal compiler error. We now get this internal error at configure time and avoid using the type.
* * arith.c (bignum): Previously static function now exposed as external.Kaz Kylheku2012-04-081-0/+37
| | | | | | | | | | | | | | | | | | | | * arith.h (bignum): Declared. * configure: Added check for tm_gmtoff and tm_tmzone fields being present in struct tm. * eval.c (eval_init): New intrinsic functions: time, time-usec. * lib.c (num): If the cnum is outside of the fixnum range, then construct a bignum. (time_sec, time_sec_usec): New functions. * lib.h (mut): Slight change to macro to eliminate compiler warning. (time_sec, time_sec_usec): Declared. * txr.1: Stub section for time and time-usec. * txr.vim: Highlighting for time and time-usec.
* Fixes to get configure ccname=g++ working on OSX Lion.Kaz Kylheku2012-04-071-36/+57
| | | | | | | | | | | | | | | | * Makefile (conftest.syms): Use -n flag in nm so that the output is not alphabetically sorted, but numerically. We need this to get the symbols ordered by increasing offset. * configure (read_syms): New function. Factors out logic used in two places for reading the output of nm. On OSX Lion, it looks like we do not get symbol sizes but offsets only, when compiling with g++. The symbols are in an S section. When compiling with gcc, we get a common C section with symbol sizes. So the hack is to use the deltas between offsets to get the sizes. The objects had to be re-ordered in decreasing rank so alignment doesn't create padding that will get counted as the size. Interleaved dummy objects of type char should also work.

(gc_set, gc_mutated): New functions. * gc.h (gc_set, gc_mutated): Declared. * hash.c (hash_mark): Changed useless use of vecref_l to vecref. (gethash_f): Use set when assigning through *found since it is a possible mutation. * lib.c (car_l, cdr_l, vecref_l): Got rid of loc macro uses. Using the value properly is going to be the caller's responsibility. (push): push may be a mutation, so use set. (intern): Uset set to mutate a hash entry. (acons_new_l, aconsq_new_l): Use set when replacing *list. * lib.h (PTR_BIT): New preprocessor symbol.

(struct any, struct cons, struct string, struct sym, struct package, struct func, struct vec, struct lazy_cons, struct cobj, struct env, struct bignum, struct flonum): Use obj_common macro to defined common fields. (loc): Macro removed. (set, mut): Macros conditionally defined for real functionality. (list_collect, list_collect_nconc, list_collect_append): Replace mutating operations with set. * match.c (dest_set, v_cat, v_output, v_filter): Replace mutating operations with set. * stream.c (string_in_get_line, string_in_get_char, strlist_out_put_string, strlist_out_put_char): Replace mutating operations with set. * unwind.c (uw_register_subtype): Replace mutating operation with set.

But this was broken, since op_defun was expecting the parameter list to be a proper list containing only bindable symbols, ruling out the use of the consing dot for rest parameter as well as the colon keyword symbol for optional parmeters.
