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.

David Given df1cdf7762 Add the sys directory for libc functions which use system calls; move the
malloc functions in there.

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 5fd8d772fd Move the string-to-float functions into core, after marking them as
ACKCONF_WANT_FLOAT.

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.

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 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.

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.

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.

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
David Given 0d77cb8279 We can build our first C file. 2016-08-07 21:56:53 +02:00
