I'll be interested in seeing the improvements. As a reference, this is what I get in an Intel 6700K when I compare gcc 5.4 (Ofast flto) vs published Intel results. 23x in libquantum, and over 40% in many benchmarks. I think that it is mostly from AoS vs SoA and loop transformations. 5.4 OfastICCperlbench12.9812.100.93bzip27.647.851.03gcc12.3011.000.89mcf14.0821.781.55gobmk8.308.981.08hmmer9...

Hi Tobias- The loop fusion you mention is the one in libquantum/cpu2006 ? Or something else in cpu2017 ? -Thx Dibyendu -----Original Message----- From: llvm-dev [mailto:llvm-dev-bounces at lists.llvm.org] On Behalf Of Tobias Grosser via llvm-dev Sent: Wednesday, August 16, 2017 10:10 AM To: renau at uncore.io; llvm-dev at lists.llvm.org Subject: Re: [llvm-dev] Heroic LLVM optimizations Hi

cmake is a big dependency, but it doesn't seem to have many dependencies itself. They say it's just a C++ compiler and a make (not necessarily gnu). Probably there are one or two more than that :-) A shell, for a start; git or tar/gzip etc. The current *nix source tarball is 6.4 MB gzipped. Just for fun I grabbed it and tried building on four machines: - 3.4 GHz i7 3770 with Ubuntu
