Instrumentation Options (Using the GNU Compiler Collection (GCC))

MEDS：增强型内存错误检测Sanitizer

• -fsanitize=address：Enable AddressSanitizer. The option cannot be combined with -fsanitize=thread or -fsanitize=hwaddress.
• -fsanitize=hwaddress：Enable Hardware-assisted AddressSanitizer. The option cannot be combined with -fsanitize=thread or -fsanitize=address, and is currently only available on AArch64.
• -fsanitize=thread：Enable ThreadSanitizer. The option cannot be combined with -fsanitize=address, -fsanitize=leak.
• -fsanitize=leak：Enable LeakSanitizer. The option cannot be combined with -fsanitize=thread. 
• -fsanitize-recover[=opts]：Enabling this option for a sanitizer component causes it to attempt to continue running the program as if no error happened.
• -mno-omit-leaf-frame-pointer：Keep the frame pointer in a register for leaf functions. 
• -fno-omit-frame-pointer：Keep the frame pointer for all functions, which might make debugging harder.

 

cmake 同时启用asan和tsan：

-DCMAKE_C_FLAGS="-g -O2 -fno-omit-frame-pointer -fsanitize=address -fsanitize=thread -fno-sanitize-recover=all"
-DCMAKE_CXX_FLAGS="-g -O2 -fno-omit-frame-pointer -fsanitize=address -fsanitize=thread -fno-sanitize-recover=all "

 

启动时的选项

export ASAN_OPTIONS=halt_on_error=0:malloc_context_size=100:log_path=./asan.log
export TSAN_OPTIONS=log_path=./tsan.log

export ASAN_OPTIONS=halt_on_error=0:malloc_context_size=100:detect_leaks=0:verbosity=1:log_path=./asan_raw.log
