Thanks for answering. I didn't know about missing support for push/pop
directives. ☺

pas2js does not parse the asm block, so it has no idea what it uses.

You already alerted me (via mantis) about this compiler behavior regarding
asm blocks, but the compiler should provide some option to disable it in
specific units without disabling the entire compiler optimization.

Hm... thanks for suggesting, but I'll not use it. 😀 I'm looking for
optimizations, this workaround would grows the code.

It would be nice some keyword (e.g: *volatile*), directive and/or some
special comment like "{%no-optimize}" to disable the optimization in
specific unit parts. Any unconditional compiler behavior that removes
things from the programmer code maybe will cause serious problems in large
applications. Just my 2 cents.
