4716083f3f Fixed a signed char shift optimization so that it won't be used on signed int also. 
(It would lose significant bits from the high byte.)

377f31d085 Fixed soft80 shutdown. 
A call to $FDA3 cannot be used because it re-enables the BASIC ROM. If a large program (such as Contiki's webbrowser80) has destructor code or data "behind" that ROM, then the program might crash when it tries to quit gracefully. Changing that code to set CIA2_PRA works well enough.

Add PC Engine-specific substitutes for memcpy() and memmove().
 2015-10-24 17:10:25 +02:00
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.

Greg King
8e9bf4d419 Changed the way that ld65 handles bad offset/start segment attributes, and reports memory area overflows. 
1. Offset/start attributes within a memory area are ignored after an overflow.
2. If a previous segment ends past an offset/start address, then that address is not used.
3. Short map files were generated for memory overflows; now, they are generated for bad offset/start addresses, too.

67cd0c2197 Added .asize and .isize pseudo variables 
These pseudo variables will return the size of the accumulator/index
in bits.

For the 65816 instruction set .ASIZE/.ISIZE will return either 8 or 16,
depending on the current size of the operand in immediate addressing
mode.

For all other CPU instruction sets, .ASIZE/.ISIZE will always return 8.

For example:

	; Reverse Subtract with Accumulator
	; A = memory - A
	.macro rsb param
		.if .asize = 8
			eor	#$ff
		.else
			eor	#$ffff
		.endif
		sec
		adc	param
	.endmacro
