Create new data frame with conditional sums
Dear Jason,
I do not think that the solution based on aggregate offered by GPT was
correct. That quasi-solution only aggregates for every individual level.
As I understand, you want the cumulative sum. The idea was proposed by
Bert; you need only to sort first based on the cutoff (e.g. using an
ordered factor). And then only extract the last value for each level. If
Pct is unique, than you

I just checkout release_38 branches of llvm, clang and polly and built
it on and x86 Ubuntu with cmake:
CMAKE_BUILD_TYPE="Debug"
CMAKE_INSTALL_PREFIX="$HOME/toolchain/install/llvm-3.8"
LLVM_TARGETS_TO_BUILD="X86"
cmake -G "Unix Makefiles" \
-DBUILD_SHARED_LIBS="ON" \
