well, not that i know of, but it should work almost as is. most of these
are actually differences between the HP assembler and the GNU assembler,
rather than differences between SOM and ELF.

shouldn't need the labels, the assembler recognizes these. but you need
to put % in front of all the register names in order for the GNU
assembler to accept the input. (ldo 0x40(%sp),%sp, etc)
