Re: [cc65] Optimizer removing embedded asm

Hi Dan,

> The -O flag seems to be optimizing away certain asm("")-style lines

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.

Optimizations can be disabled via pragma - however only on function
scope, here's an example:
