MaskRay added inline comments.
================ Comment at: llvm/lib/Transforms/Instrumentation/PGOInstrumentation.cpp:623 // Compute Hash value for the CFG: the lower 32 bits are CRC32 of the index -// value of each BB in the CFG. The higher 32 bits record the number of edges. +// value of each BB in the CFG. The higher 32 bits are the CR32 of the numbers +// of selects, indirect calls, mem ops and edges. ---------------- To make sure I understand: we use two CRCs instead of one CRC because we want to extract low/high 32 bits for debugging purposes? Otherwise, we can just use one CRC.
