Reduce verbiage of lit.local.cfg files We can just split targets_to_build in one place and make it immutable. llvm-svn: 210496 2014-06-10 06:42:55 +08:00			`if not 'PowerPC' in config.root.targets:`
[LoopVectorizer] Count dependencies of consecutive pointers as uniforms For the purpose of calculating the cost of the loop at various vectorization factors, we need to count dependencies of consecutive pointers as uniforms (which means that the VF = 1 cost is used for all overall VF values). For example, the TSVC benchmark function s173 has: ... %3 = add nsw i64 %indvars.iv, 16000 %arrayidx8 = getelementptr inbounds %struct.GlobalData* @global_data, i64 0, i32 0, i64 %3 ... and we must realize that the add will be a scalar in order to correctly deduce it to be profitable to vectorize this on PowerPC with VSX enabled. In fact, all dependencies of a consecutive pointer must be a scalar (uniform), and so we simply need to add all consecutive pointers to the worklist that currently detects collects uniforms. Fixes PR19296. llvm-svn: 205387 2014-04-02 10:34:49 +08:00			`config.unsupported = True`
