Hi Muhui,

If you want just the coverage information you can remove the -fsanitize=address flag from the command line.

Hi If so, is it able to disable this check. All I need is just to get the BB coverage information Regards Muhui Alexander Potapenko <glider at google.com>于2018年9月5日 周三下午6:57写道：

This is a known problem in SPECCPU2006, see https://github.com/google/sanitizers/wiki/AddressSanitizerFoundBugs On Wed, Sep 5, 2018 at 7:36 AM Muhui Jiang via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Hi > > I am using SanitizerCoverage feature supported by clang to get the basicblock coverage. > > my tested binaries are spec cpu2006.

I just want to compile the binaries with instrumented coverage information so that I can calculate the bb coverage.
