Subject: Make a std::vector a SmallVector<*, 32> like the other vectors in the same
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=443997de8b0eb538aac833390358f30c952f85fc;p=oota-llvm.git

Make a std::vector a SmallVector<*, 32> like the other vectors in the same
function. This seems to be about a 1.5% speedup of -scalarrepl on test-suite
with SPEC2000 and SPEC2006.
