[llvm-dev] Using Multiple Sanitizers on one program

Hi LLVM people,

Not sure whether this is the best place to ask this.

Given the source of a program, I would like to detect both uninitialized
reads and out-of-bounds memory accesses. The latter can be done with the
Address Sanitizer (ASan) and the first using the Memory Sanitizer (MSan).

Is there a way to use both at the same time? The --fsanitize option only
seems support one of these. What is the reason for this restriction?

Kind regards,
Nathan
