b1576e2c77 Add support for negative constants in external initialisers. 2016-12-31 19:43:03 +00:00

a01523a893 Allow programs to override binit() (so they can register their own modules). 2016-12-31 17:39:51 +00:00

c3e1ef1064 B patch table names shouldn't be in the B symbol namespace. 2016-12-31 00:14:28 +00:00

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.

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.

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.

4485d89b23 Hook the B compiler up to the compiler driver. 2016-11-27 20:48:07 +01:00

5bce5fc4da Change the extension used by Basic files for .b to .bas, to avoid conflicts 
with B.

707585b67d Perform initial (i.e. feature complete and compiling, but not necessarily 
working) port of the B compiler to EM.

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!

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.

e9fe1d70a6 Fix (or at least, work around) an issue with library order. Make sure the Basic 
error symbols are actually defined.

fd91851005 Add enough return types to the K&R C that the ACK builds (on Linux) using clang 
now.

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.

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.

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.

612e38f1c6 Remove the old make-based build system, plus some big chunks of horribly 
obsolete protomake build system.

856eb120b3 Add files which got missed in the initial build pass. 2016-08-20 14:04:17 +02:00

4d24666432 Move util/data into modules/src/em_data, for consistency with the other 
modules.

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.

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).

a200a2fb53 Replaced the funky and hard-to-compile ACK malloc with a much smaller 
and simpler one stolen from K&R. libc builds now.

variables.

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.

363d13cc2f C preprocessor; tabgen; now the pc86 boot.s builds using the ack 
toolchain.

2770a83837 More programs, more libraries. src/modules build files are now saner. 2016-07-23 00:30:31 +02:00
