8e8d112029 Added pce-specific substitutes for memcpy() and memmove().
They are smaller and faster because they take advantage of the pce CPU's block-copy instructions.

Also, made a small improvement to the common memmove(), so that it is similar to the pce version.

76a5a72403 Adjusted current working directory initialization on Apple and Atari.
Moving __cwd from BSS into INITBSS does of course ;-) not only impact the CBM targets but all targets with disk I/O support.

Note: Code using `__cwd-1` may trigger an ld65 range error because __cwd may end up at the very begining of a segment. As far as I see this is an ld65 bug which I'm not try to fix - at least here.

0ee9b2e446 Changed run location of INIT segment.
So far the INIT segment was run from the later heap+stack. Now the INIT segment is run from the later BSS. The background is that so far the INIT segment was pretty small (from $80 to $180 bytes). But upcoming changes will increase the INIT segment in certain scenarios up to ~ $1000 bytes. So programs with very limited heap+stack might just not been able to move the INIT segment to its run location. But moving the INIT segment to the later BSS allows it to occupy the later BSS+heap+stack.

In order to allow that the constructors are _NOT_ allowed anymore to access the BSS. Rather they must use the DATA segment or the new INITBSS segment. The latter isn't cleared at any point so the constructors may use it to expose values to the main program. However they must make sure to always write the values as they are not pre-initialized.

8a880580dc Reduced the size of the moveinit subroutine.
Made other changes that were recommended by Oliver.

* Used self-modifying code in the subroutine.
* The INIT segment doesn't need to be optional (it's used by the start-up file).

ee54f7f40c optimized clrscr for size 2015-10-06 19:33:43 +02:00
Greg King
074e10d288 Adapted, to the c64 target, the INIT-segment overlay scheme from the apple2 targets.
When a program starts running, INIT is moved from one place to another place.  Then, INIT's code is executed; and, the first place is re-used for variables.  After the INIT code has finished, the second place can be re-used by the heap and the C stack.  That means that initiation code and data won't waste any RAM space after they stop being needed.

219905c6bc Fix two string output functions' handling of their buffer-size parameter.
That parameter's type is unsigned; but, the functions return an int.  If the size is too big for a signed integer, then return an error code.
If the size is zero, then don't write anything into a buffer (the buffer pointer may be NULL).  But, do format and count the arguments.

3c1cd0d867 Added cmdline support to exec().
The starting point is the CALL2051:REM <cmdline> approach. It uses the BASIC input buffer at $200. ProDOS stores the name of the loaded program at $280 (which we want for argv[0]) leaving us with 128 char buffer. If we run the program via exec() we don't need the CALL2051 but only the REM token (which is just one char). So have a maximum cmdline length of 126 (plus a terminating zero).

There's no specification for ProDOS BIN file cmdline parameters so exec() just supports the CALL2051:REM <cmdline> approach. In contrast ProDOS SYS files allow for a 'startup filename'. A ProDOS filename is short than 126 chars so having exec() general cut the cmdline after 126 chars seems reasonable. If the SYS file we exec() allows for less we cut the cmdline further.

Our 'loader.system' SYS file however allows for an unusually 126 char long "startup filename" as it is targeted towards cc65 BIN porgrams with their 126 cmdline length.

2c975d3642 Create static drivers directly from source files.
Up to now static drivers were created via co65 from dynamic drivers. However there was an issue with that approach:

The dynamic drivers are "o65 simple files" which obligates that they start with the 'code' segment. However dynamic drivers need to start with the module header - which is written to. For dynamic drivers this isn't more than a conceptual issue because they are always contain a 'data' segment and may therefore only be loaded into writable memory.

However when dynamic drivers are converted to static drivers using co65 then that issue becomes a real problem as then the 'code' segment may end up in non-writable memory - and thus writing to the module header fails.

Instead of changing the way dynamic drivers work I opted to rather make static driver creation totally independent from dynamic drivers. This allows to place the module header in the 'data' segment (see 'module.mac').

d6c3bd29ac Renamed JUMPTABLE and cleaned up module.cfg.
This change was suppsed to fix the issue that the former JUMPTABLE is merked as 'ro' while it is actually written to in several scenarios. When drivers are converted using co65 and then compiled into ROMs the JUMPTABLE isn't copied to RAM and therefore the write operations in question fail.

However unfortunately I didn't succeed in changing that :-( Just setting the former JUMPTABLE to 'rw' broke the drivers. So I placed the DATA segment directly after the former JUMPTABLE segment. This made the drivers converted with co65 work again - obviously after changing libsrc/Makefile:235 from '--code-label' to '--data-label'. But the actual dynamic drivers still didn't work as the former JUMPTABLE wasn't placed as the beginning of the loaded file anymore. That effect could be changed by exchanging src/ld65/o65.c:1391 with src/ld65/o65.c:1394 but doing so broke the drivers again :-((

3ef184bdd6 Corrected the default upper limits of some mouse drivers' bounding box.
The upper limits need to be one less than the screen sizes because the minimum co-ordinate is zero instead of one.

1d6000213c Removed references to $TRAVIS from Makefiles.
After all it seems much cleaner to explicitly control the behaviour from the .travis.yml file than to behave differently "under the hood" when detecting a Travis CI build.

e335d2564d Added code that disables C128 BASIC's sprite-motion interrupt-handler.
That lets the mouse drivers control a sprite directly through the VIC's registers.

1c73fa0a00 Moved .PHONY below definitions it refers to.
I must admit that I don't understand why but obviously it is necessary to place .PHONY below the definition of variables it refers to - although those variables are recursively expanded ones! Not doing so made libsrc/Makefile build only three target libraries.

3f0af9b241 Have src/Makefile and libsrc/Make use disjoint work directories.
Building the clean target in src or libsrc should only delete stuff created by the make in those directories. Having both separated allows the Travis CI build to replace the native binaries with cross built binaries while keeping everything else.

44ccb27549 Changed Makefile.inc handling.
It seems more appropriate to trigger the inclusion of Makefile.inc via $TARGET (instead of $SRCDIR). This is btw. more consistent with extzp.s inclusion which is triggered via $TARGET too.

d001a6f1a0 Have _heapmaxavail() work as advertised.
The cc65 doc explicitly states that the return value of _heapmaxavail() can be used as parameter of malloc(). To actually allow for that the size of HEAP_ADMIN_SPACE has to be substracted from the raw size of the largest free heap block.

b477023783 Turn off mouse polling interrupt if the mouse hasn't been moved for
some time. Turn it back on when the mouse is moved again.
Since the polling interrupt runs at a rather high frequency (1kHz),
this saves many processor cycles when the mouse is inactive.

e320fe3db8 Added 'install' target.
The 'install' target primarily aims to support pacaking tools. Therefore...
- It just presumes a "capable" install program to be present.
- There's intentionally no 'uninstall' target.
