Re: [cc65] How to force a read from a memory mapped register w/o volatile

The above meant non-inline assembler. Regarding inline assembler
http://www.cc65.org/doc/cc65-9.html
says:

"Note: Inline assembler statements are subject to all optimizations
done by the compiler. There is currently no way to protect an inline
assembler statement from being moved or removed completely by the
optimizer. If in doubt, check the generated assembler output, or
disable optimizations."
