Hi
I am using SanitizerCoverage feature supported by clang to get the basicblock coverage.
my tested binaries are spec cpu2006. I compiled the binary with the option COPTIMIZE = -O0 -fsanitize=address -fsanitize-coverage=bb -flto -fno-strict-aliasing -std=gnu89 -gdwarf-3
After the compiling process is end. I run the 400.perlbench. with the command ASAN_OPTIONS=coverage=1 ./perlbench. However, the AddressSanitizer detect the global buffer overflow and I could not run the perlbench properly.
Is there anything wrong or I missed some configurations? I just want to compile the binaries with instrumented coverage information so that I can calculate the bb coverage. Many Thanks
