While this is likely not exactly what you want....
assembler directives -- doc @
http://www.xgc.com/manuals/gcc-erc32-ug/p4node59.html
laptop:~$ cat f.s
.arch msp430x110
.text
.org 0xE000
nop
.end
ok....
msp430-gcc -c f.s -o f.out
this will compile. If you want to link and load, then it will look for
a entry point, main.
to convert from elf to hex (intel hex)
msp430-objcopy -O ihex f.out f.hex
hope this helps... my program ... this was large. If you want to link
and load, then you likely need to define an entry point.
