David Given 8b8910595a Add proper support for negative constants in external initialisers. 2017-01-01 17:56:53 +00:00
David Given 049aff9f33 Remove the negative-constant code from the compiler; I think it's going to 
break a=-1 (with no spaces). Backed out changeset dead3363ac7d.
 2017-01-01 17:44:55 +00:00
David Given 374e7a1c57 Add support for the ~ operator. 2017-01-01 17:40:06 +00:00
David Given b1576e2c77 Add support for negative constants in external initialisers. 2016-12-31 19:43:03 +00:00
David Given a01523a893 Allow programs to override binit() (so they can register their own modules). 2016-12-31 17:39:51 +00:00
David Given 803b81e3f4 Add support for the xor operator. 2016-12-31 17:36:12 +00:00
David Given c3e1ef1064 B patch table names shouldn't be in the B symbol namespace. 2016-12-31 00:14:28 +00:00
David Given fa02a855e8 Fix issue where !x was actually calculating !!x. 2016-12-31 00:14:04 +00:00
David Given ebd424e7f1 First draft of the B module code; a module name can now be specified as a 
compiler flag, which is used to set the name of the patch table. The compiler
now understands C preprocessor line directives. Extend the standard library
somewhat.
 2016-12-29 17:10:21 +00:00
David Given e50f4be710 Merge from default. 2016-12-26 19:44:48 +00:00
David Given 04e54d6cb1 Run lang/basic/lib through clang-format. 2016-12-12 21:16:32 +01:00
David Given a53b51001b Ansify function definitions. 2016-12-12 21:15:25 +01:00
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 bbcc08a6b6 Fix putchar() return value. 2016-11-28 21:38:46 +01:00
David Given 9f34262f95 Implement enough libb to make 'Hello, world!' work. 2016-11-27 22:05:15 +01:00
David Given b9665c7c99 Fix some basic showstopping bugs; compilation now works up to failing to find 
the libb standard library.
 2016-11-27 21:08:14 +01:00
David Given 4485d89b23 Hook the B compiler up to the compiler driver. 2016-11-27 20:48:07 +01:00
David Given 5bce5fc4da Change the extension used by Basic files for .b to .bas, to avoid conflicts 
with B.
 2016-11-27 20:38:33 +01:00
David Given 707585b67d Perform initial (i.e. feature complete and compiling, but not necessarily 
working) port of the B compiler to EM.
 2016-11-27 20:28:19 +01:00
David Given cfc723250f Initial EM-ification; start threading word size stuff through the code. 2016-11-27 11:58:59 +01:00
David Given a69045c0e4 Import aap@github's B compiler. 2016-11-27 11:37:25 +01:00
David Given 3e69d1185a Fix a whole lot more stray prototypes. 2016-11-24 21:47:40 +01:00
David Given b8a2935f2b Fix more invalid prototypes of stdlib functions; build dependency fix. 2016-11-24 21:26:05 +01:00
David Given c084f9f224 Remove the Mark() and Release() procedures from the Pascal compiler and 
standard library, because they never worked and come from an achingly old
version of the Pascal specification. Fix the implementations of New() and
Dispose() to use the standard C memory allocator rather than rolling their own
(also in C). Write test!
 2016-11-24 20:35:26 +01:00
David Given 9481487e3d Implement calloc() (accidentally got dropped with the malloc rewrite). 2016-11-23 22:16:25 +01:00
David Given 745eb8f17b Now _errsym and _erlsym are defined in the standard library, don't define them 
in the program.
 2016-11-16 21:13:00 +01:00
David Given e9fe1d70a6 Fix (or at least, work around) an issue with library order. Make sure the Basic 
error symbols are actually defined.
 2016-11-13 13:28:09 +01:00
David Given 4d7c27391f Merge. 2016-11-10 22:06:08 +01:00
David Given fd91851005 Add enough return types to the K&R C that the ACK builds (on Linux) using clang 
now.
 2016-11-10 22:04:18 +01:00
David Given 57cb99ade1 Remove sys_time in favour of directly calling time(). 2016-11-09 21:52:04 +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 4d24666432 Move util/data into modules/src/em_data, for consistency with the other 
modules.
 2016-08-14 14:09:38 +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 262c5fedcf Biggish refactor to break cycles; my build rules were full of them. cpm builds, 
which requires top and topgen.
 2016-08-14 01:39:40 +02:00
David Given e0b8bd221d Pascal runtime library now builds. 2016-08-13 13:07:19 +02:00
David Given e770d09dc8 Pascal compiler builds. 2016-08-13 13:03:06 +02:00
David Given 00c67fcc0e Modula-2 runtime library now builds. 2016-08-13 12:43:44 +02:00
David Given dbf8332bf0 Fixed a small bug where two line number directives next to each other wouldn't 
be parsed properly (the second one would be treated as Modula-2 syntax).
 2016-08-13 12:21:16 +02:00
David Given 8e869b56e7 The Modula-2 compiler now builds. 2016-08-13 00:02:21 +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
David Given b50dc4214a Add check for undefined variables. Find undefined variables. Fix undefined 
variables.
 2016-08-05 00:01:55 +02:00
David Given 5e84be70fd Massive ackbuilder refactor --- cleaner and more expressive. Lists 
are automatically flattened (leading to better build files), and the
list and filename functions are vastly more orthogonal.
 2016-08-04 23:51:19 +02:00
David Given b2bb4ce3b2 Builds libend (the simplest library). Becoming obvious I need to rework the way 
ackbuilder deals with lists.
 2016-07-30 00:39:22 +02:00
David Given 363d13cc2f C preprocessor; tabgen; now the pc86 boot.s builds using the ack 
toolchain.
 2016-07-29 00:22:49 +02:00
David Given 2770a83837 More programs, more libraries. src/modules build files are now saner. 2016-07-23 00:30:31 +02:00
David Given 1fdc69fb97 cemcom.ansi now builds. 2016-07-19 23:43:14 +02:00
David Given 2d2497c318 ackbuilder rules files now require absolute paths in external variables 
(otherwise commands which change directory don't work).
 2016-07-18 23:16:27 +02:00
David Given bcf3408e36 More stuff builds; almost the C compiler now. 2016-07-14 23:54:13 +02:00

George Koehler 7ef9b79c11 Merge deletion of many undead files. 2012-09-23 15:31:16 -04:00
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.

See http://sourceforge.net/mailarchive/message.php?msg_id=29823032
 2012-09-20 22:26:32 -04:00
George Koehler 800d4ae032 Fix cemcom.ansi for 64-bit hosts. 
Hosts with sizeof(arith) == sizeof(long) == 8 need to set full_mask[1]
through full_mask[8].  Because MAXSIZE == 8, we only had full_mask[0]
through full_mask[7].  This fix declares arith full_mask[MAXSIZE + 1]
and prevents a fatal error: "array full_mask too small for this machine"
