f470576822 it's now possible to use symbols that are the same name as 6502 instructions 
because these are now prefixed internally before generating assembly.

af6be44676 ir: adding register usage inspections 
fix compiler problems with untrimmed inlined asm, and when only a single return statement is present in a subroutine
 2022-09-30 20:25:00 +02:00

0d4dd385b8 added '%ir' to write inline IR code, '%asm' is now only for real 6502 assembly. 
(%ir is probably only used in the library modules for the virtual machine target)
