Subject: [PowerPC] Don't return false from PPC::isVSLDOIShuffleMask
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c0c10f20a20f281b79adf4b9cf995c5144338078;p=oota-llvm.git

[PowerPC] Don't return false from PPC::isVSLDOIShuffleMask

PPC::isVSLDOIShuffleMask should return -1, not false, when the shuffle
predicate should be false.

Noticed by inspection; no test case (yet).
