999d57401c Added a version of memset() that uses the HuC6280's TII instruction to get more speed. 2015-11-06 23:59:19 -05:00

8180ac20d3 Added code to handle the special case of a zero-length move. 
Added more tests of memcpy() and memmove().

Greg King
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.
* 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).

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.
