8a880580dc Reduced the size of the moveinit subroutine. 
Made other changes that were recommended by Oliver.
* Changed its name from move_init to moveinit.
* Used self-modifying code in the subroutine.
* The INIT segment doesn't need to be optional (it's used by the start-up file).

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.

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.

94eb2a2ed7 Some fine tuning of the mouse driver interface harmonization. 2014-01-17 21:09:15 +01:00
Oliver Schmidt
4065cb1983 Harmonized interface between mouse drivers and callbacks. 
The Apple2 doesn't have sprites so the Apple2 mouse callbacks place a special character on the text screen to indicate the mouse position. In order to support the necessary character removing and redrawing the Apple2 mouse driver called the Apple2 mouse callbacks in an "unusual way". So far so (sort of) good.

However the upcoming Atari mouse driver aims to support both "sprite-type" mouse callbacks as well as "text-char-type" mouse callbacks. Therefore the interface between mouse drivers and callbacks needs to be extended to allow the mouse callbacks to hide their different types from the mouse driver.

The nature of this change can be seen best by looking at the Apple2 file modifications. The CBM drivers and callbacks (at least the current ones) don't benefit from this change.

Greg King
e63bf1cde1 Used a library-reference method to calibrate lightpen drivers. 
The mouse reference is a pointer.  If it's NULL, the driver uses a default.  If it's non-NULL, then it points to a function that the driver can call.  That function will adjust the driver's calibration value.  It could ask the user to adjust the pen; or, it could read a file that holds a value from a previous calibration.

Application writers can choose how it's done: a function that's provided by the library, a custom function, or nothing.

619b215260 Added library reference em_libref to EMD interface. 
Occasionally dynamically drivers suffer from not being to refer to
content in the C library. Therefore I added a mechanism to allow
a C library for a certian target to define a symbol that will be
handed over to dynamic drivers for that target. Then the drivers
can use their refernce to that symbol to access content in the C
library.

4aa00e84e1 Removed tgi_load() and all corresponding infrastructure. The idea behind tgi_load() was to be able to describe a TGI mode in a target-neutral way by resolution and colordepth. However it turned out that there arn't any cc65 targets sharing any resolution. As a result the only working target-independent approach for a TGI program is to call tgi_loaddriver(tgi_stddrv); and then look up the resolution provided - and to adapt to that resolution.

routine for all other CBM systems. CBM510/610 do also have a TOD clock, so a
similar function as in the C64 could be used ...
