Hi Kun Ling & Bergstrom, Thanks a lot for your earlier responses. We did use the benchmarks in llvm testsuite for comparing execution time taken by clang & gcc. It appears that clang is slower than gcc for cases where floating point operations are involved and recursive calls are involved (note that pic/pie was enabled for both gcc as well as clang ). 1) For lag in execution time due to

Hi All, Could anyone point me to some good benchmarking tools to measure the runtime performance of clang compiled C++ applications. Thanks ! - Jyoti -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20131003/3cc029f1/attachment.html>
