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.

David Given b85c25e4e5 Fix resource leak.

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that getpw() is obsolete.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().

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.

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.

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.

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.

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.

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.

George Koehler 0131ca4d46 Delete 689 undead files.
These files "magically reappeared" after the conversion from CVS to
Mercurial.  The old CVS repository deleted these files but did not
record *when* it deleted these files.  The conversion resurrected these
files because they have no history of deletion.  These files were
probably deleted before year 1995.  The CVS repository begins to record
deletions around 1995.

These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted.  There is no way to fix
this, because the CVS repository provides no dates of deletion.

dtrg 5c5f711cbb Done a major overhaul of the way target include files are installed and
how platform libraries are built. The ARCH pm variable has now been
renamed PLATFORM (which is more accurate) and a different ARCH
variable added, which represents the CPU family rather than the
hardware platform.
