◆ ConstantTSC
| bool llvm::xray::XRayFileHeader::ConstantTSC |
Whether the CPU that produced the timestamp counters (TSC) move at a constant rate.
Definition at line 38 of file XRayRecord.h.
Referenced by llvm::xray::FDRTraceWriter::FDRTraceWriter(), and llvm::xray::readBinaryFormatHeader().
◆ CycleFrequency
| uint64_t llvm::xray::XRayFileHeader::CycleFrequency = 0 |
The number of cycles per second for the CPU that produced the timestamp counter (TSC) values.
Useful for estimating the amount of time that elapsed between two TSCs on some platforms.
