Subject: bfin: drop _ASSIGN_BANG
X-Git-Tag: upstream/2.43~63
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1cc4b7d755afd8cce917ca43d2db18a7442b468a;p=platform%2Fupstream%2Fbinutils.git

bfin: drop _ASSIGN_BANG

A few testcases demonstrate that "=!" isn't supposed to be an
individual token, since "= !" is used in a number of places. So far
lexing that to a single token worked because of the scrubber being
overly aggressive in removing whitespace. As that's going to change,
replace uses by separate ASSIGN and BANG.
