* tests: implicitly generate empty .expected files.Kaz Kylheku2021-04-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Makefile (%.expected): New implicit rule. Whenever a test requires a .expected file, if it is missing, we create an empty one. This file will be treated as an intermediate by GNU Make, which means that it will be deleted when make terminates. * tests/012/compile.tl: Some of the .tl files no longer have an .expected file, so we have to test for that in the catenating logic. * tests/008/call-2.expected, * tests/008/no-stdin-hang.expected, * tests/011/macros-3.expected, * tests/011/patmatch.expected, * tests/012/aseq.expected, * tests/012/ashwin.expected, * tests/012/compile.tl, * tests/012/cont.expected, * tests/012/defset.expected, * tests/012/ifa.expected, * tests/012/oop-seq.expected, * tests/012/parse.expected, * tests/012/quasi.expected, * tests/012/quine.expected, * tests/012/seq.expected, * tests/012/struct.expected, * tests/012/stslot.expected, * tests/014/dgram-stream.expected, * tests/014/in6addr-str.expected, * tests/014/inaddr-str.expected, * tests/014/socket-basic.expected, * tests/015/awk-fconv.expected, * tests/015/split.expected, * tests/015/trim.expected, * tests/016/arith.expected, * tests/016/ud-arith.expected, * tests/017/ffi-misc.expected, * tests/018/chmod.expected: Empty file deleted.
* build: calm restless yacc.Kaz Kylheku2021-04-081-6/+1
| | | | | | | | | | * Makefile (%.tab.c %.tab.h): Remove the trick of keeping the old y.tab.h file if it has not changed. This was once a good idea, but now that we have a proper grouped targets pattern rule which knows that y.tab.h depends on and is produced from parser.y, the trick causes y.tab.h to be perpetually out of date due to its old time stamp, and so yacc is run on every build.
* M1: Fix sed issue.Kaz Kylheku2021-03-241-1/+5
| | | | | | | | | | | | | | | | | The MacOS sed doesn't accept semicolon termination for commands involving defining labels or branching to labels. This is not a new issue, but it is revealed on newer MacOS because the sed now complains about unused labels. In the sed command ':x; /whatever/ { ...; tx }', everything after the initial : is interpreted as a label. * Makefile (DEPGEN): Split the sed command's syntax up into logical lines using multiple -e commands, applying some formatting with indentation to try to keep it readable. It looks like multiple -e options just glue together to make a program, as if they were lines of code; one -e can define a label referenced by another, and even the closing brace can be treated as a separate command.
* build: use yacc pattern rule with "y" as stem.Kaz Kylheku2021-03-221-9/+1
| | | | | | | | | | | | | | | | Thanks to a recent discussion in the GNU Make mailing list about some issue related to grouped patterns, I hit upon the realization that the rule y.tab.h y.tab.c: parser.y has a common stem, y, which can be exploited to write a pattern rule. This is only active in maintainer mode; in user mode, the y.tab.h and y.tab.c are separately produced from .shipped files. * Makefile (y.tab.h): Eliminate rule which detects a removed y.tab.h. (y.tab.c): Delete rule, replacing with new rule. (%.tab.c %.tab.h): New pattern rule, which groups the targets together.
* tests: fix retest logic for parallel operation.Kaz Kylheku2021-03-161-7/+5
| | | | | | | | | I'm giving up and just using a recursive make invocation for the "retest" target. * Makefile (retest): Depend on nothing. Remove the tst directory and invoke make tests recursively. (tests.clean): Target removed.
* build: cautiously allow parallel builds.Kaz Kylheku2021-03-011-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Over two years ago, I disabled parallel building with a .NOTPARALLEL: directive in the Makefile, due to some rules that depended on order of updates of their prerequisites. Today the situation is better. It looks like there are just a few rules that have to be fixed, all in the area of executing tests. Let us not enable that by default, though, to protect downstream users from themselves. Some operating system distribution builds optimistically run make -j N on all the packages, and then have to deal with sporadic breakages when some of those packages have parallel build bugs. We can prevent TXR from ever being implicated in such a breakage by turning off parallel building even if make -j requests it. There will now be a ./configure --parallelmake option to allow parallel builds, off by default. The --maintainer configuration mode will flip that default; configuring in maintainer mode will enable parallel builds, unless explicitly disabled with --no-parallelmake. * Makefile (.NOTPARALLEL): Conditionally assert, if parallelmake is false. (tst/tests/014/dgram-stream.ok, tst/tests/014/socket-basic.ok): Enforce order between these two tests. They clash in their use of network ports so cannot run at the same time. (test.clean): test.clean must finish executing before tests; enforce order. * configure (parallelmake, parallelmake_given): New variables. (help text): Add parallelmake option to help. (gen_config_make): Generate the parallelmake make variable into config.make. New script section, defaulting parallelmake to y in maintainer mode.
* txr: pattern function calls are non-matching.Kaz Kylheku2021-02-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch causes TXR to treat calls to verticatl functions, as well as the @(call) directive to be considered non-matching directives, so that opening the data source is deferred. This allows included .txr files to call the funtions that they define, without the side effect of standard input being read. * match.c (open_data_source): Function refactored to reduce duplication. c->data is checked first, and if it is not t, nothing is done, making the function cheaper in the frequent case. The non_matching_dir condition changes. We now check that the first element of the first spec is a non-nil symbol. If it has a function binding as a vertical function, then that is considered non_matching. (dir_tables_init): Treat @(call) as a non-matching directive. * Makefile (tst/tests/008/no-stdin-hang.ok): Add -n argument for non-interactive, which will cause stdin to be read in that test case if there is a regression in this change. If make tests is run in a terminal, this will hang make tests. * tests/no-stdin-hang.txr: New file. * tests/no-stdin-hang.expected: New file.
* @(rebind): bugfix: don't clobber right side variable.Kaz Kylheku2021-01-301-0/+1
| | | | | | | | | | | | | | | | | | | | | * Makefile (tst/tests/000/binding.ok): Pass -B to txr for this new test. * match.c (v_rebind): Fix gaping copy-and-paste bug here, which causes rebind to take on the behavior of local/forget; it takes all symbols that appear as its arguments from the environment and produces an environment in which they don't exist. What we want is to remove the left variables from the environment, and since that is a nested pattern, the right way to do that is to flatten it. Bug reported by Frank Schwidom. * tests/000/binding.txr: New file. * tests/000/binding.expected: New file. * txr.1: Improve documentation of @(rebind), also making improvements in @(set) documentation.
* build: add rule for updating .shipped material.Kaz Kylheku2021-01-241-0/+3
| | | | * Makefile (%.shipped): New pattern rule.
* build: support linker flags/libs separation.Kaz Kylheku2021-01-141-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Our build system lumps all linker options together. The correct way is that linker flags are separated info flags and libs. Also, we respond to the LDFLAGS variable but ignore LDLIBS which is incorrect. Other issues are fixed. All that is fixed here. * Makefile (TXR_CFLAGS): Interpolate $(CFLAGS) last, so that options coming from CFLAGS can override previous options. (TXR_LDFLAGS): Interpolate $(LDFLAGS) last; same reason. (TXR_LDLIBS): New variable. (LINK_PROG): Put $(TXR_LDFLAGS) with the options, before the -o, and put $(TXR_LDLIBS) at the end. * configure (conf_ldlibs, platform_ldlibs): New variables. (usage text): Document platform-ldlibs and adjust documentation of platform-ldflags. (gen_config_make): Generate PLATFORM_LDLIBS and CONF_LDLIBS now needed by Makefile. (mainline): Adjusts various recipes to use conf_ldlibs instead of conf_ldflags, or in some cases both. In the case of libffi where we use pkg-config, we use the special pgk-config options to separately extract the flags and libs. We use EXTRA_LDLIBS instead of EXTRA_LDFLAGS in some conftest invocations, as necessary.

* build: Android support.Kaz Kylheku2020-12-231-0/+6
| | | | | | | | | | * Makefile (conftest.android): New helper target for testing for Android toolchain, via presence of __ANDROID__ preprocessor symbol, similarly to how we detect Darwin. * configure: New test for Android. This is mutually exclusive agains Darwin. On Android, we add some necessary feature selection macros to the compiler command line.
* configure: replace nm-based trick for sizesKaz Kylheku2020-10-091-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | The trick of declaring static arrays whose size is the value of an integer is not working with newer gcc 10 on Cygwin, because that compiler is rearranging the order of the arrays and adding padding. Basically, the writing on the wall is that this is not a good approach. I'm switching to a different approach. By initializing a suitable C structure (which contains character arrays) in a particular way, we can create a .o file in which a shell script is embedded. We can pull out the shell script and evaluate it to get the sizes of types. * Makefile (conftest.syms): Rule removed. (conftest.clean): Don't remove conftest.syms. * configure (conftest_syms, read_syms): Functions removed. (LANG, LC_ALL): New environment variables. This is needed because we are using tr to process a binary file; we can't have it trying to decode multi-byte characters. (mainline): Use new trick for obtaining variables like SIZEOF_INT.
* time: move time functions out of lib.c into time.c.Kaz Kylheku2020-10-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Makefile (OBJS): Add new time.o. * eval.c (eval_init): Registration of time functions is removed from here; it is done in time_init now, in time.c. * hash.c: Must #include "time.h" now. * lib.c (time_s, time_local_s, time_utc_s, time_string_s, time_parse_s, year_s, month_s, day_s, hour_s, min_s, sec_s, dst_s, gmtoff_s, zone_s): Variable definitions removed. These are now in time.c. Also declared in time.h.

Now in time.h. * rand.c: Must #include "time.h" now. * time.c: New file. * time.h: New file.
* configure: only detect lex in maintainer mode.Kaz Kylheku2020-09-241-2/+2
| | | | | | | | | * Makefile (lex.yy.c): Move rule into maintainer conditional. * configure: Describe maintainer variable in help text. Move lex check into maintainer conditional. * lex.yy.c.shipped: New file.
* configure: detect yacc only in maintainer mode.Kaz Kylheku2020-09-241-7/+1
| | | | | | | | | | | * Makefile (YACC_FLAGS): Removed. We don't need these because we won't be trying to get newer Bison to behave like older Bison. (y.tab.c): Drop reference to $(YACC_FLAGS). * configure: Entire yacc-detecting section is conditional on the maintainer Boolean variable. If the yacc program is detected as Bison, check for version 2.5 and fail if not found.
* parser: commit Bison-2.5-generated code.Kaz Kylheku2020-09-241-11/+8
| | | | | | | | | | | | | * Makefile (BS_LIC_FROM, BS_LIC_TO): Variables removed. (y.tab.c): Remove all filtering hacks. Don't remove the license from y.tab.c. Don't remove yyparse declaration from y.tab.h. Provide a pattern rule for producing any missing file X from X.shipped. That's how y.tab.c and y.tab.h get produced from y.tab.c.shipped and y.tab.h.shipped, respectively, in user mode. * y.tab.c.shipped, y.tab.h.shipped: New files, generated using Bison 2.5.
* new: maintainer mode.Kaz Kylheku2020-09-241-0/+4
| | | | | | | | | | | | | | | | | | There is now a ./configure --maintainer mode which establishes a variable called maintainer in config.make, with a y value. The initial use for maintainer mode will be that the Yacc parser (the y.tab.c and y.tab.h) files will no longer be regenerated whenever the parser.y file is newer. In the following commit, I will add a generated parser. * Makefile (y.tab.h, y.tab.c): These rules are now only enabled in maintainer mode via an ifeq. * configure (maintainer): New variable. (gen_config_make): Generate maintainer make variable definition in config.make.
* Makefile: stray tabs.Kaz Kylheku2020-09-241-1/+1
| | | | | * Makefile (lex.yy.c): Remove tabs that are being used for alignment instead of spaces.
* New tests for chmod.Kaz Kyheku2020-02-071-0/+2
| | | | | | | | | | | | | | | | The chmod fixes in the previous several commits were caught by this. * Makefile (tst/tests/018/chmod.ok): Set up TXR_ARGS for this test to give it the location of the temporary file to use as the object for testing permissions. (tst/tests/018): Disable TXR_DBG_OPTS for new directory. * tests/018/chmod.tl: New file. * tests/018/chmod.expected: Likewise. * tests/perm.tl: Likewise.
* build: drop config.log in favor of reconfigureKaz Kyheku2020-01-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | The configure command line is now turned into an executable script called reconfigure which can be invoked to repeat the config. * Makefile (distclean): Whether in a configured or state or not, try to remove reconfigure. In the configured state, don't remove config.log. (If distclean is invoked when not configured, the config.* pattern will remove config.log). * configure: rewrite the logic which turns the command line into text. It is now robust against spaces, quotes and meta-charaters. Moreover, the printed representation is chosen according to good heuristics to minimize unnecessary quoting and escaping. The config line is written into an executable script called reconfigure. This is now done twice; it is done immediately, so that we save the command line even if the configure subsequently fails. A comment is added to reconfigure indicating that configure didn't succeed. Then after a successful run through the tests, we save it again, without the cautionary comment. Help texts updated.
* build: deal with the mess of new Bison warnings.Kaz Kylheku2020-01-101-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | Newer versions of Bison produce spurious warnings in Yacc mode about %pure-parser being not POSIX conforming and also deprecated. Plus some strange fluff about "fix-its" that can be applied if option --update is specified. Let's detect at configure time whether the Yacc program being used is actually Bison 3.0 or greater, and if so, give it some flags to shut up these warnings. * Makefile (YACC_FLAGS): New variable, conditionally set based on yacc_is_newer_bison, also new variable, that being generated into config.make. (y.tab.c): Invoke $(TXR_YACC) with $(YACC_FLAGS). (conftest.yacc-version): New phony target for running Yacc with --version, out of the configure script. * configure (yacc_is_newer_bison): New variable. (gen_config_make): Generate yacc_is_newer_bison make variable. New test for whether Yacc is Bison. If so, and the version is >= 3.0, sets the yacc_is_newer_bison variable to y.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Binary search tree nodes are being added as a basic heap data type. The C type tag is TNOD, and the Lisp type is tnode. Binary search tree nodes have three elements: a key, a left child and a right child. The printed notation is #N(key left right). Quasiquoting is supported: ^#N(,foo ,bar) but not splicing. Because tnodes have three elements, they they fit into TXR's four-word heap cell, not requiring any additional memory allocation. These nodes are going to be the basis for a binary search tree container, which will use the scapegoat tree algorithm for maintaining balance. * tree.c, tree.h: New files. * Makefile (OBJS): Adding tree.o. * eval.c (expand_qquote_rec): Recurse through tnode cells, so unquotes work inside #N syntax. * gc.c (finalize): Add TNOD to no-op case in switch; tnodes don't require finalization. (mark_obj): Traverse tnode cell. * hash.c (equal_hash): Add TNOD case. * lib.c (tnode_s): New symbol variable. (seq_kind_tab): New entry for TNOD, mapping to SEQ_NOTSEQ.

| | | | | | | | | | | | | | | | | * Makefile (OBJS): New object file, chksums/md5.o. * chksum.c (sha256_ensure_buf): Renamed to chksum_ensure_buf and made generic so MD5 code can borrow it. (sha256_stream, sha256): Call chksum_ensure_buf instead of sha256_ensure_buf, passing in new length and hash name parameters. (md5_stream_impl, md5_buf, md5_str): New static functions. (md5_stream, md5): New functions. (chksum_init): Register md5-stream and md5 intrinsics. * chksum.h (md5_stream, md5): Declared. * chksums/md5.c, chksums/md5.h: New files.

| | | | | | | | | | | | * Makefile (OBJS): Add chksums/crc32.o. * chksum.c (crc32_stream, crc32): New functions. (chksum_init): Register crc32-stream and crc32 intrinsic functions. * chksums/crc32.c, chksums/crc32.h: New files. * txr.1: Documented.
* * Makefile (OBJS): New objects chksum.o and chksums/sha256.o.Kaz Kylheku2019-06-231-1/+1
| | | | | | | | | | * chksum.c, chksum.h, chksums/sha256.c, chksums/sha256.h: New files. * lib.c (init): Call chksum_init. * txr.1: Documented. * LICENSE: Add SHA-256 copyright notice.
* Makefile: non-configured distclean removes tlo's.Kaz Kylheku2019-06-121-1/+1
| | | | | | * Makefile (distclean): distclean target for not-configured state removes .tlo files by wildcard, including the old .tlo2 files that we used to generate once.
* build: allow $(pwd)/configure to work.Kaz Kylheku2019-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | When the build is being done in the source directory, allow the configure script to be executed via path names other than just ./configure, such as an absolute path. Some distros use this. * configure (build_in_srcdir): New variable. (inode): New function. Rather than checking whether "$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.
* build: remove nonexistent config option.Kaz Kylheku2019-02-261-2/+2
| | | | | | * Makefile (dbg/%-win.o, opt/%-win.o): Don't pass CONFIG_WIN_MAIN=1 preprocessor symbol; it's not referenced anywhere, and never has been.
* build: get rid of .tlo2 files.Kaz Kylheku2019-02-081-12/+3
| | | | | | | | | | | | | | | After the defvar bugfix in the previous commit, the only differences between .tlo and .tlo2 files are the names of a few gensyms here and there. In other words, they are identical code; therefore, there is no point in compiling them. * Makefile (STDLIB_TLOS2): Variable removed. (%.tlo2): Implicit rule removed. (stage1 stage2): Phony targets removed. (all): Directly depends on $(STDLIB_TLOS) without stage1 intermediary. (clean-tlo): Don't remove $(STDLIB_TLOS2).
* install: broken when using separate build dir.Kaz Kylheku2019-01-251-2/+1
| | | | | | | | * Makefile (install): Drop the $(top_srcdir) prefix from share/txr/stdlib materials. This fails for the .tlo files which are only found in the build directory, not the source directory. The .txr and .tl files are found in both, thanks to symlinks; for those it works either way.
* mpi: remove unused mplogic module.Kaz Kylheku2019-01-181-1/+1
| | | | * Makefile (MPI_OBJ_BASE): remove mplogic.o.

* bugfix: LDFLAGS not pulled in.Kaz Kylheku2018-12-121-1/+1
| | | | | * Makefile (TXR_LDFLAGS): Fix use of wrong assignment operator which clobbers the previous assignment of $(LDFLAGS).
* More reasonable fallback for self path.Kaz Kylheku2018-05-041-2/+4
| | | | | | | | | | | | | | | | * Makefile (opt/txr.o, dbg/txr.o): Set up TXR_REL_PATH preprocessor symbol on command line which specifies the hard installation path derived from the configure prefix. * txr.c (get_self_path): The fallback implementation simply returns TXR_REL_PATH. This will work if in fact the executable is installed at that path. What it means is that the build of TXR which uses this fallback get_self_path will not support relocation: the installation cannot be moved to another directory, yet still find its supporting files. This is better than what we are replacing: not working even in the original installation directory, if not invoked by an absolute path.
* Makefile: use order-only between early and late tlo-s.Kaz Kylheku2018-04-291-1/+1
| | | | | | | | | * Makefile: make STDLIB_EARLY_TLOS order-only prerequisites of STDLIB_LATE_TLOS, rather than conventional prerequisites. This means that the early tlo-s are built or rebuilt before the late ones, but there is no other dependency expressed: an update of early tlo-s doesn't force late tlo-s to be out-of-date and updated also.
* build: fix failure due to .tlo compilation order.Kaz Kylheku2018-04-261-0/+6
| | | | | | | | | | | | | On newer GNU Make versions, $(wildcard ...) doesn't sort its results, and so we compile .tlo files in an arbitrary order. For the most part, this is fine. However, there is a complicated circular dependency involving the error.tl file requiring it to be compiled first. * Makefile (STLIB_EARLY_PATS, STDLIB_EARLY_TLOS, STDLIB_LATE_TLOS): New variables. Use these to express a dependency which causes error.tlo to be built first.
* build: remove dubious license header from y.tab.c.Kaz Kylheku2018-04-161-0/+10
| | | | | | | | | | | | | | | | | | | | | | | The GNU Bison parser has a GPL header in the parser skeleton which gets copied to the generated parser. The GPL asserts that the entire file falls under the GPL (but as a special exception, it may be used in any manner whatsoever in a program, as long as it isn't used as the skeleton of a parser generator). The GPL assertion is false; the file is not entirely derived from the skeleton but contains code directly copied from parser.y, as well as tables generated from parser.y's original grammar. Since we are definitely not using this as a parser skeleton for a parser generator and are thus allowed to do whatever we want such as compiling this into proprietary object files, I'm removing the copyright header as a build step. You never know; someone could package up a built directory of TXR containing a Bison-generated y.tab.c, and then it looks like there is a GPL-ed file in the project. * Makefile (CM): New variable, needed for interpolating literal commas into macro calls. (BS_LIC_FROM, BS_LIC_TO): New variables. (y.tab.c): Filter y.tab.c to remove GPL comment.
* Makefile: bugfix: shell quoting issue in macro.Kaz Kylheku2018-04-161-1/+1
| | | | | | | | | | * Makefile (SH): The $(1) macro argument is substituted into a shell '...' quote. It may contain single quotes itself, so these have to be mapped to the famous '\'' sequence. Currently, only one SH call has '...' syntax in it: one in the y.tab.c rule which calls sed -e '/yyparse/d'. That works anyway, and the quotes could be removed from it; but let's fix the SH macro.
* build: compiling Lisp requires ./txr to exist.Kaz Kylheku2018-04-121-2/+2
| | | | | | | | * Makfile (%.tlo, %.tlo2): We take advantage of Gmake's order-only prerequisites to express this dependency. This means that .tlo and .tlo2 files are not considered outdated when $(PROG) is newer; it only ensures that $(PROG) cannot be missing when a .tlo or .tlo2 must be updated.
* build: prevent make parallelization.Kaz Kylheku2018-04-121-0/+2
| | | | | | * Makefile: add .NOTPARALLEL: special target. This Makfile doesn't support parallel builds; it relies on left-to-right execution of prerequisites in some places.
* build: don't rebuild tlo's all the time.Kaz Kylheku2018-04-071-2/+2
| | | | | | | | * Makefile (%.tlo, %.tlo2): Drop dependency on $(TXR). Of course, the dependency is strictly correct, but most changes to TXR are irrelevant. Moreover, not all relevant dependencies are in place anyway; if we change compile.tl, only the compile.tlo is recompiled.
* stdlib: all code read under sys package.Kaz Kylheku2018-04-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Another part of the preparation for an upcoming change. All library code is now read in the sys package, so any symbols that are interned (local variables and whatnot) are in sys and will not be exposed to user code. We have to overcome some annoyances to achieve this: - We have to stay away from the symbols exp or var, because they are now sys:exp and sys:var with their special meaning. - Instances in which a symbol of the same name exists in both sys and usr present a problem; the plain symbol now is the usr one. For instance rplaca will refer to sys:rplaca, so a small amount of code has to explicitly use usr:rplaca. * Makefile (COMPILE_TL): Change to the sys package before compiling library code. * lisplib.c (lisplib_try_load): Bind *package* to the system package. * share/txr/stdlib/asm.tl, share/txr/stdlib/compiler.tl: Remove in-package macro invocation; we don't need this since all files are loaded or compiled in the sys package. * share/txr/stdlib/build.tl, share/txr/stdlib/cadr.tl, share/txr/stdlib/conv.tl, share/txr/stdlib/doloop.tl, share/txr/stdlib/error.tl, share/txr/stdlib/error.tl, share/txr/stdlib/except.tl, share/txr/stdlib/ffi.tl, share/txr/stdlib/getopts.tl, share/txr/stdlib/getput.tl, share/txr/stdlib/hash.tl, share/txr/stdlib/ifa.tl, share/txr/stdlib/keyparams.tl, share/txr/stdlib/op.tl, share/txr/stdlib/package.tl, share/txr/stdlib/path-test.tl, share/txr/stdlib/place.tl, share/txr/stdlib/pmac.tl, share/txr/stdlib/socket.tl, share/txr/stdlib/stream-wrap.tl, share/txr/stdlib/struct.tl, share/txr/stdlib/tagbody.tl, share/txr/stdlib/termios.tl, share/txr/stdlib/trace.tl share/txr/stdlib/txr-case.tl, share/txr/stdlib/type.tl, share/txr/stdlib/ver.tl, share/txr/stdlib/with-resources.tl, share/txr/stdlib/with-stream.tl, share/txr/stdlib/yield.tl: Deal with the various usr versus sys symbol issues.
* build: support compiling stdlib.Kaz Kylheku2018-04-051-5/+30
| | | | | | | | | | | | * Makefile (STDLIB_SRCS, STDLIB_TLOS, STDLIB_TLOS2): New variables. (COMPILE_TL): New recipe macro. (%.tlo, %.tlo2): New pattern rules. (all): Depend on new stage1 and stage2 targets. (stage1, stage2): New phony targets. (clean): Add clean-tlo dependency. (clean-tlo): New phony target. (install): Install .tlo files also.
* New: virtual machine with assembler.Kaz Kylheku2018-03-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit is the start of compiler work to make TXR Lisp execute faster. In six days of part time work, we now have a register-style virtual machine with 32 instructions, handling exceptions, unwind-protect, lexical closures, and global environment access/mutation. We have a complete assembler and disassembler for this machine. The assembler supports labels with forward referencing with backpatching, and features pseudo-ops: for instance the (mov ...) pseudo-instruction chooses one of three kinds of specific move instruction based on the operands. * Makelfile (OBJS): Add vm.o. * eval.c (lookup_sym_lisp1): Static function becomes external; the virtual machine needs to use this to support that style of lookup. * genvmop.txr: New file. This is the generator for the "vmop.h" header. * lib.c (func_vm): New function. (generic_funcall): Handle the FVM function type via new vm_execute_closure function. In the variadic case, we want to avoid the argument copying which we do for the sake of C functions that get their fixed arguments directly, and then just the trailing arguments. Thus the code is restructured a bit in order to switch twice on the function type. (init): Call vm_init. * lib.h (functype_t): New enum member FVM. (struct func): New member in the .f union: vm_desc. (func_vm): Declared. * lisplib.c (set_dlt_entries_impl): New static function, formed from set_dlt_entries. (set_dlt_entries): Reduced to wrapper for set_dlt_entries_impl, passing in the user package. (set_dlt_entries_sys): New static function: like set_dlt_entries but targetting the sys package. (asm_instantiate, asm_set_entries): New static functions. (lisplib_init): Auto-load the sys:assembler class. * share/txr/stdlib/asm.tl: New file. * vm.c, vm.h, vmop.h: New files.
