Peter Collingbourne a77d9f726a DataFlowSanitizer: Add a debugging feature to help us track nonzero labels. ... Summary: When the -dfsan-debug-nonzero-labels parameter is supplied, the code is instrumented such that when a call parameter, return value or load produces a nonzero label, the function __dfsan_nonzero_label is called. The idea is that a debugger breakpoint can be set on this function in a nominally label-free program to help identify any bugs in the instrumentation pass causing labels to be introduced.
