David Given 79fd34dac6 Call atexit handlers properly, avoiding a NPE and seg fault every time a 
program exits.
 2018-09-09 18:51:00 +02:00
David Given fd94e219d4 Remove the attic. 2018-06-23 23:16:22 +02:00
David Given 59dbdea48a Move mktemp to sys; attic getgrent as noone will ever use this. 2018-06-23 23:15:42 +02:00
David Given 3f10299f43 Move the portable time code into core. clock() goes into sys (as it calls 
times()).
 2018-06-23 19:49:29 +02:00
David Given 64ae1d7583 Move time() into sys; change the name of the variable which controls it. 2018-06-23 19:40:50 +02:00
David Given bb78fd158c Move the big gnarly functions like system() and popen() into sys, and make them 
build.
 2018-06-23 19:18:16 +02:00
David Given 6a729b846a Move stdio into (mostly) sys. 2018-06-23 18:54:40 +02:00
David Given af22b7ea85 Change stdio to use atexit() rather than the internal __clean variable; this 
breaks the dependency between exit/atexit and stdio. Buffers are no longer
flushed on abort() (because it's pretty risky). Move the relevant functions
into sys/core.
 2018-06-23 18:35:45 +02:00
David Given f744a21699 All the opendir()/readdir() stuff is obsolete because it's all implemented in 
terms of open() and read(), which isn't how it's done any more; move the
functions into an attic.
 2018-06-23 18:25:26 +02:00
David Given df1cdf7762 Add the sys directory for libc functions which use system calls; move the 
malloc functions in there.
 2018-06-23 18:08:03 +02:00
David Given c4e4505a73 Move the errno functions into core. 2018-06-23 17:52:15 +02:00
David Given 538eefb573 Get em22 working. Remove the leading-underscore system calls from its libsys. 2018-06-23 15:57:57 +02:00
David Given 680b4071b7 Made the two OSX platforms work with the new libc layout. 2018-06-23 12:55:59 +02:00
David Given b727b7affd Make linuxppc work. 2018-06-23 12:41:54 +02:00
David Given b267b56ad9 Made linux68k work; commoned up all the generic linux includes. 2018-06-23 12:35:17 +02:00
David Given 66815ff987 Make linux386 work with the new libc layout. 2018-06-23 12:13:33 +02:00
David Given 32c881474e Create a basic and probably wrong common unistd.h, which replaces the plat one. 
Made this work with cpm (but nothing else yet).
 2018-06-23 11:46:55 +02:00
David Given dd0f959245 Move assert into core. 2018-06-23 11:16:06 +02:00
David Given 5fd8d772fd Move the string-to-float functions into core, after marking them as 
ACKCONF_WANT_FLOAT.
 2018-06-23 11:14:24 +02:00
David Given 94ffa3ba88 libc floating point and stdio floating point can now be turned on and off using 
ACKCONF variables.
 2018-06-23 00:04:14 +02:00
David Given 9bf1d548fc Rearrange the libc config files, ready for adding new options. 2018-06-22 23:43:15 +02:00
David Given c0276416d8 Move some more libc functions into core. 2018-06-22 22:20:02 +02:00
David Given d1cdb07719 Realise that the libc core can safely call other libc core functions, even if 
they're not defined in the core: so putw() can call stdio stuff, for example.
So the earlier concept of pureness isn't necessary. Rename accordingly.
 2018-06-21 23:24:23 +02:00
David Given 62025c92bd The ctype functions are pure. 2018-06-21 23:06:29 +02:00
David Given d9d7ffe0d7 The maths library is pure. 2018-06-21 23:00:33 +02:00
David Given f9c059812b Moved the setjmp functions into the new pure directoy. 2018-06-21 22:55:42 +02:00
David Given 32f47b1d24 Move the pure locale functions into the new pure directory. 2018-06-21 22:54:25 +02:00
David Given b9d2f353d9 Move the pure stdlib functions into the new pure directory. 2018-06-21 22:52:31 +02:00
David Given 4dbdb7d8d5 Rethink the libc layout. 2018-06-21 22:47:02 +02:00
David Given 83e1b2ad94 Move the str and mem functions into the new src/core. 2018-06-21 22:39:08 +02:00
David Given 93f39e4bbf Run libcc.ansi through clang-format. 2018-06-21 22:33:47 +02:00
David Given 13e195d19f Warning fixes. 2018-06-17 15:42:26 +02:00
David Given 7eaa235fd1 Bodge the ancient em monitor library into building as a libsys for the em22 
plat. It's completely untested, but it builds and makes e.out executables.
 2018-06-13 21:44:25 +09:00
David Given d623440c77 Add the core of a simple em22 platform. Unfortunately it doesn't work; the old 
em libmon vanished decades ago (or never existed), and also ass appears to have
a different idea of what the em opcodes are to everything else and gets
confused.
 2018-06-10 20:25:48 +09:00
David Given b85c25e4e5 Fix resource leak. 
Closes: #75

George Koehler 75ae957c75 Don't check ferror(fp) when reading fp. 
If feof(fp) or ferror(fp) was set, then our libc returned EOF for all
later reads without trying to read.  Our libc now behaves like BSD
(and probably Illumos and musl) by checking only feof(fp).  For
difference, glibc doesn't check feof(fp).

I described the difference between our libc and BSD libc in
https://sourceforge.net/p/tack/mailman/message/35430300/

George Koehler 54028e403e Delete unused misc/getpw.c from libc. 
@hexcoder- reported in https://github.com/davidgiven/ack/issues/57
that our getpw() has bugs.

I don't fix these bugs, because Illumos and Linux manual pages say
that getpw() is obsolete.  The function can overflow its buffer, so it
is never safe to use.  Our libc did not build getpw().
 2017-10-28 14:25:39 -04:00
George Koehler 0a2dfd650d Delete malloc.h and tgmath.h from libc. 
This malloc.h might get confused with the private malloc.h in our
libc.  C programs should #include <stdlib.h> for malloc().

This tgmath.h has no useful content, and never worked because
complex.h is missing.

Touch build.lua (by deleting some whitespace) so the *.h globs see
the deletions.
 2017-10-28 14:24:35 -04:00
George Koehler b00a2c906d Build fdopen(), hypot(), putenv() in libc. 
These functions are in POSIX; hypot() is in C99.  Also build cabs()
because it rides with hypot(), but don't declare cabs() in any header
file, because our compiler can't parse C99 "double complex" type.

Touch build.lua so it sees that .c files moved.
 2017-10-28 13:33:57 -04:00
David Given c569ca15d8 Clean up how the language libraries refer to plat headers; they should be using 
the +pkg forms of the rules and getting the headers via the paths in descr,
rather than depending on the +headers version.
 2016-12-05 21:05:24 +01:00
David Given 9481487e3d Implement calloc() (accidentally got dropped with the malloc rewrite). 2016-11-23 22:16:25 +01:00
George Koehler 08f9869a63 Remove unused defines from lang/cem/libcc.ansi/math/localmath.h 
This undoes part of bfeb736, and returns to using DBL_MAX_EXP and
DBL_MIN_EXP from float.h.

Add a dependency on math/localmath.h and other local header files so
libc is rebuilt when those headers change.
 2016-11-06 15:49:47 -05:00
George Koehler 19ca28e22f Undo commit bfeb736 for lang/cem/libcc.ansi/headers/float.h 
This restores the correct values of DBL_MAX, DBL_MIN_EXP, and related
constants.  This fixes some range checks within libc, causing
atof("-36e90") and atof("1.44e-288") to return the correct values.
 2016-11-06 15:01:25 -05:00
David Given f67c98e239 Distributions are a pain --- let's not bother any more. Instead, we just tag 
the repository and download a complete snapshot, old and ancient stuff and all.
 2016-09-02 23:00:38 +02:00
David Given 612e38f1c6 Remove the old make-based build system, plus some big chunks of horribly 
obsolete protomake build system.
 2016-09-02 22:17:51 +02:00
David Given 856eb120b3 Add files which got missed in the initial build pass. 2016-08-20 14:04:17 +02:00
David Given b549980af2 Wasn't exporting the plat headers; refactor to make this a little cleaner. 2016-08-14 11:01:36 +02:00
David Given a200a2fb53 Replaced the funky and hard-to-compile ACK malloc with a much smaller 
and simpler one stolen from K&R. libc builds now.
 2016-08-11 00:30:32 +02:00
David Given 3ce4e53aa9 Most of libc builds now (missing malloc). 2016-08-08 23:55:47 +02:00
