Mike added this already, please make sure to not add it twice :-)

(It still allows older as well, so "Also match" maybe?)

Did you make sure all of these are correct and expected?  Are the
testcases still strict enough, or should you add -mno-pcrel to the
options, instead?  Or maybe test both -mpcrel and -mno-pcrel?  Etc.

You also add a "p?", is that expected?  Should be in the changelog
then :-)

Even better is to not put the instruction names in the filename, but
heh, maybe that would be too simple ;-)
