| | | | | | | | | | | | | | | * Makefile (PROG): Removing ./ prefix from variable name; adding it to invocations of $(PROG) in some rules. (txr.o): Pass several strings as macros on the command line: TXR_REL_PATH, EXE_SUFF and PROG_NAME. * configure (bindir, datadir, mandir): These variables become just relative paths from the prefix. * txr.c (sysroot): Use the TXR_REL_PATH, EXE_SUFF and PROG_NAME preprocessor symbols defined on the command line to avoid hard-coding strings like "bin/txr" and "bin/txr.exe" which actually should reflect the value of the bindir variable.
* * txr.c (get_self_path): Fix spelling of GetModuleFileName.Kaz Kylheku2014-06-102-3/+17
| | | | | | Add missing parentheses in expression. (sysroot_init): On Windows, filter progpath to change backslashes to forward slashes.

(get_self_path, sysroot_helper, sysroot, sysroot_init): New static functions. Sysroot creates a stdlib variable. (main): Initialize progname_u8 value, and call sysroot_init.

(extract): Print bindings or "false" if opt_print_bindings is true. * stream.c (output_produced): Variable removed. (stdio_put_string, stdio_put_char, stdio_put_byte): Remove update of output_produced. * stream.h (output_produced): Declaration removed. * txr.1: Documentation updated. * txr.c (txr_main): Option 'b' does nothing. 'B', 'l', 'a', and '--lisp-bindings' set opt_print_bindings to 1. * txr.h (opt_nobindings): Declaration removed. (opt_print_bindings): Declared. * unwind.c (uw_throw): When exiting due to a query error or file error, print false when opt_print_bindings is true.

| | | | | | | | | | | | | | | | | | | | | | | | | | namely that empty strings and vectors are not nil. The nullify function is introduced. It is also exposed to users, as is the existing make_like function. * eval.c (mapcarv, mappendv, lazy_mapcar, lazy_mapcarv): Use nullify to handle non-list inputs correctly. (eval_init): Registering make_like and nullify as intrinsics. * lib.c (copy_list, to_seq, list_collect_nconc, list_collect_append, reverse, lazy_appendv_func, lazy_appendv, ldiff, memq, memql, memqual, remq, remql, remqual, remove_if, keep_if, rem_lazy_rec, remq_lazy, remql_lazy, remqual_lazy, remove_if_lazy, keep_if_lazy, countqual, countql, countq, count_if, some_satisfy, all_satisfy, none_satisfy, do_chain, chainv, do_and, andv, do_or, orv, cat_vec, assoc, assql, mapcar, mapcon, mappend, sort, multi_sort, find, find_if, posqual, posql, posq, pos, pos_if, set_diff, search): Use nullify for correctness. Some functions fixed so return sequence matches type of input sequence. (nullify): New function. * lib.h (nullify): Declared. * txr.1: Documented nullify and ake-like.

| | | | | numbers if they are defined. In a newer flex, they are prefixed by YY_.
* * configure (lang_flags): Removing -D_BSD_SOURCEKaz Kylheku2014-06-052-2/+52
| | | | | | | | | | | | from lang_flags. Adding a test for determining which flag reveals BSD functions. This is due to the braindamaged way feature selection macros work on FreeBSD. There is no way to say "give me only the functions from a certain version of the Unix spec, plus traditional BSD functions", so we have to resort to using the internal symbol __BSD_VISIBLE. Also, changing the detection test for daemon function to the pointer-based approach.
* * configure (lang_flags): drop -D_POSIX_C_SOURCE=199309L.Kaz Kylheku2014-06-042-1/+6

* Changes for FreeBSD 9.Kaz Kylheku2014-06-043-2/+23
| | | | | | | | | * configure: Use pointer-based test for timegm, because -Werror=implicit-function-declaration does not work in the gcc 4.2 used on FreeBSD 9. * parser.l: Check for Flex 2.5.9 and earlier which don't have yylex_destroy. Thanks to Marcus Breiing.
* * configure: Changes for building on Solaris 10 using theKaz Kylheku2014-06-042-7/+18
| | | | | | | | | /usr/bin/xpg4/sh shell. Solaris' /bin/sh does not like test -e. Adding break to the new shell existence testing loop so we use the first shell in the list. Solaris wants _XOPEN_SOURCE=500 to reveal certain functions. Fix breakage in the make utility detection, and also use the $make variable everywhere instead of make.
* * configure: Defend against legacy, non-POSIX /bin/sh implementations.Kaz Kylheku2014-06-042-0/+29
| | | | | | | We boostrap using #!/bin/sh, but try to detect a better shell and re-execute the script with that shell. Furthermore, we now set up the SHELL variable in config.make, so that make uses that shell for executing build recipes.
* * eval.c (eval_lisp1): Function removed.Kaz Kylheku2014-06-032-10/+12
| | | | | | (op_dwim, dwim_locs): Removing silly logic of separately calling eval_lisp1 on the functor, and eval_lisp1_args on its arguments, since lisp1 evaluation treats all position the same way.

The issue being solved here is the accuracy of the gc_set function. The existing impelmentation is too conservative. It has no generation information about the memory location being stored, and so it assumes the worst: that it is a location in the middle of a gen 1 object. This is sub-optimal, creating unacceptable pressure against the checkobj array and, worse, as a consequence causing unreachable gen 0 objects to be tenured into gen 1. To solve this problem, we replace "val *" pointers with a structure of type "loc" which keeps track of the object too, which lets us discover the generation. I tried another approach: using just a pointer with a bitfield indicating the generation. This turned out to have a serious issue: such a bitfield goes stale when the object is moved to a different generation. The object holding the memory location is in gen 1, but the annotated pointer still indicates gen 0. The gc_set function then makes the wrong decision, and premature reclamation takes place. * combi.c (perm_init_common, comb_gen_fun_common, rcomb_gen_fun_common, rcomb_list_gen_fun): Update to new interfaces for managing mutation. * debug.c (debug): Update to new interfaces for managing mutation.

* Generational GC tweaks.Kaz Kylheku2014-03-292-19/+45
| | | | | | | | | | | | | | | | | | * gc.c (make_obj): If we have room in the freshobj array, but are out of objects, then call more. Without this, we don't take proper advantage of this nursing area. (gc): Set the full_gc flag after doing gc, in preparation for next time. If we know full GC is coming, we can adjust some behaviors. Increase the threshold for calling the more() function to be the same as in the non-generational case: less than 3/4 of the size of a heap scavenged. (gc_set): Now does nothing if it is known that a full gc is coming. Also, in the checkobj array overflow case when we invoke gc, there is no point in adding obj to the array, since it must have been promoted to the mature generation. (gc_mutated): Don't bother storing the object in the array if a full GC is coming.

| | | | | | | | | | | | | | | | | | | | | | | | | | | checkobj array (via the mut macro that expands to gc_mutated). The garbage collector assumes that checkobj has only generation 0 objects, which all exist in the freshobj array, which is subject to a sweep. So gen 1 objects in checkobj are never cleaned up properly: they do not have their REACHABLE flag reset, or their generation restored to 1. To fix this, a new array for these objects is introduced separate from checkobj. * gc.c (MUTOBJ_VEC_SIZE): New preprocessor symbol. (mutobj, mutobj_idx): New static array and integer. (mark_obj): Check for REACHABLE flag before checking the full_gc flag and generation, since those cost additional memory accesses. (mark): Mark the objects in the new mutobj array. (sweep): Sweep the objects in the mutobj array. (gc): Reset mutobx_idx to zero after gc. (gc_set): Rearrange logic. In the case that the checkobj array is full and a gc is done to make room, there is no point in adding to the array: the gc pass moves all babies to generation 1, so the object that was passed into the function is no longer a baby. (gc_mutated): Rewrite in terms of mutobj rather than checkobj, fixing the bug. * HACKING: Improved documentation of GC. Describe mut macro and mutobj array.
