The GNU assembler (generally) doesn't optimize assembly files.  It just
translates them from textual form into the ELF object file format.

No; each C compiler will generate different assembly, and therefore a
different object file.  But, for the same assembly code, both the GNU
and ARM assembler are quite likely to generate the same object code.  In
any case, you can mix object code from the GNU and ARM compilers in a
single application, if you adhere to the ABI requirements.
