Low Level optimization "to the last" will often touch the ASM-Level and depends on the compiler version.
Therefore these posts contain disassembly listings from PB 8.03 generated code.
As another version of the compiler (newer or older) may generate different code, I decided to make clear that these posts are based on PB 8.03. The most easy way to do this is to make an own sub-board for the optimization theme.
