66d939df0d docs about new asm symbol prefixes 2023-12-20 22:37:46 +01:00
Irmen de Jong
6bc079c7b7 more asm symbol prefixing: variables with p8v_, subroutines with p8s_ etc
labels with p8l_ . All this to avoid symbol clashes in the generated assembly code.
Everything got its own distinguishing prefix so we're done with it once and for all and have only 1 breaking change moment.
