2012-06-13sched: fix latency of memory dependence chain edges for consistency.Andrew Trick
For store->load dependencies that may alias, we should always use TrueMemOrderLatency, which may eventually become a subtarget hook. In effect, we should guarantee at least TrueMemOrderLatency on at least one DAG path from a store to a may-alias load. This should fix the standard mode as well as -enable-aa-sched-mi". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158380 91177308-0d34-0410-b5e6-96231b3b80d8

POWER4 is a 64-bit CPU (better matched to the 970). The g3 is really the 750 (no altivec), the g4+ is the 74xx (not the 750). Patch by Andreas Tobler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158363 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-12Now that Reassociate's LinearizeExprTree can look through arbitrary expressionDuncan Sands
topologies, it is quite possible for a leaf node to have huge multiplicity, for example: x0 = x*x, x1 = x0*x0, x2 = x1*x1, ... rapidly gives a value which is x raised to a vast power (the multiplicity, or weight, of x). This patch fixes the computation of weights by correctly computing them no matter how big they are, rather than just overflowing and getting a wrong value. It turns out that the weight for a value never needs more bits to represent than the value itself, so it is enough to represent weights as APInts of the same bitwidth and do the right overflow-avoiding dance steps when computing weights. As a side-effect it reduces the number of multiplies needed in some cases of large powers. While there, in view of external uses (eg by the vectorizer) I made LinearizeExprTree static, pushing the rank computation out into users. This is progress towards fixing PR13021. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158358 91177308-0d34-0410-b5e6-96231b3b80d8
