Hi,
Recently I ran the coremark on HiFive1 board, https://www.sifive.com/products/hifive1/
With GCC, my test result is 2.66, the official data is 2.73. They are very close.
With LLVM built from https://git.llvm.org/git/llvm.git 02bcd70eea, the test result is 1.79, about 2/3 of the GCC result.
At the same time, I found similar comparison here: http://www.diva-portal.se/smash/get/diva2:1114115/FULLTEXT02.pdf In this Thesis, the LLVM dhrystone result is not good.
Are these results reasonable? Do you have internal test result? thanks a lot.
