9.29.4 MSP 430 Machine Directives

.file
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.
