This directive is ignored; it is accepted for compatibility with other
MSP 430 assemblers.
Warning: in other versions of the gnu assembler, .file is
used for the directive called .app-file in the MSP 430 support.
.line
This directive is ignored; it is accepted for compatibility with other
MSP 430 assemblers.
.arch
Sets the target microcontroller in the same way as the -mmcu
command line option.
.cpu
Sets the target architecture in the same way as the -mcpu
command line option.
.profiler
This directive instructs assembler to add new profile entry to the object file.
.refsym
This directive instructs assembler to add an undefined reference to
the symbol following the directive. The maximum symbol name length is
1023 characters. No relocation is created for this symbol; it will
exist purely for pulling in object files from archives. Note that
this reloc is not sufficient to prevent garbage collection; use a
KEEP() directive in the linker file to preserve such objects.
