Subject: fix integer negates to use the proper type for the zero vectors,
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0a00ed98f1d0734bc5bc699f58852144aa54195a;p=oota-llvm.git

fix integer negates to use the proper type for the zero vectors,
this also depends on the new "bitconvert dropping" behavior just
added to tblgen.
