I find it "advanced".

It shows a few of my imaginations around a specific software development task.

Not really. - I would like to achieve the automatic selection of a few
compilation settings by a for loop which I reduced in the shown example
to one element.

I am looking for a "convenient" way to get assembler source files from
the preferrred C compiler for some software build configurations.
I hope that I can avoid the switching of compilation results in the source
file directory hierarchy so that an occasional disassembly by a tool
like "objdump" could be compared.
