auto select correct library to import based on target, instead of having c64- and cx16- prefix variants some programs are now 100% source compatible between C64 and Cx16 targets! import libraries have been rena;med 2020-09-20 21:49:36 +00:00			`%import textio`
Got rid of problematic attempts to save status register after function calls. If you really need it (for instance for if_XX instructions) it's probably better to use a short asmsub wrapper. For function calls, register saves go via stack (to allow nested saves) for simpler cases, registers are saved in a local variable. Fixed too agressive removal of sta-lda sequence if the lda is followed by a branching instruction. Insert missing cmp #0 after functioncall if the value of the A register is needed in a comparison expression (could otherwise test wrong status flag) 2020-12-22 02:35:00 +00:00			`%import diskio`
cx16 registers should come first in subroutine arg list 2020-12-21 23:59:07 +00:00			`;%import floats`

only save A's value if needed for a return value 2020-12-22 04:43:02 +00:00			`sub start () {`
asm-subroutines that ONLY return a value in the Carry or Overflow status register can now be used in an assignment to store that value. 2020-12-22 11:44:03 +00:00			`ubyte qq`

strings and arrays are no longer directly assignable to an UWORD, you need an explicit & (address-of) now 2020-12-03 17:39:32 +00:00			`}`
