a40b3134f4 fix clobbering of A when restoring X or Y from stack 2020-12-22 04:52:46 +01:00

928611eb20 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)
