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.
