[llvm-commits] Compile time improvement patches on the way
Gurd, Preston
preston.gurd at intel.com
Wed Jan 23 15:18:52 PST 2013
One of our colleagues has spent some time profiling llvm, with the aim of reducing compile time. To that end, he has come up with a set of 11 patches, which collectively reduce the compile time of a set of benchmarks by between 14 and 16 percent, as is shown in the table below my signature.
Although one of the patches has since been rendered obsolete by changes to the llvm trunk, we plan to submit the remainder, on a commit after review basis, in the next several days.
If you happen to have expertise in the areas affected by a given patch, your review would be much appreciated!
