-/// This function reads the CPUs internal Time-Stamp Counter. This counter is
-/// used to get a precise timestamp. It differs from the usual POSIX
-/// `clock_gettime` in that (without additional computing) it can be only used
-/// for relative time measurements. The Linux kernel uses the TSC internally to
-/// implement `clock_gettime` when the clock source is set to TSC.
-///
-/// The TSC is implemented as a register in the CPU that increments its value
-/// with a constant rate. The behavior of the TSC initially was to increment the
-/// counter on each instruction. This was then changed to the current behavior
-/// (>= Pentium 4) that increments the TSC with a constant rate so that CPU
-/// frequency scaling doesn't affect the measurements.
-///
-/// The TSC is guaranteed that it won't overflow in 10 years and because it is
-/// mostly implemented as a 64bit register it doesn't overflow even in 190 years
-/// (see Intel manual).
-///
-/// One issue of the TSC is that it is unique for each logical CPU. That means
-/// that if a context switch happens between two `ReadTSC` calls it could mean
-/// that the counters could have a very large offset. Thankfully, the counters
-/// are reset to 0 at each CPU reset and the Linux kernel synchronizes all of
-/// the counters. The synchronization can be seen here (`tsc_verify_tsc_adjust`
-/// and `tsc_store_and_check_tsc_adjust`):
-/// https://github.com/torvalds/linux/blob/master/arch/x86/kernel/tsc_sync.c

-/// All claims here were taken from sections 17.17 and 2.8.6 of the Intel 64 and
-/// IA-32 Architectures Software Developer's Manual.
-///
-/// Here we use the RDTSCP instruction instead of the RDTSC instruction because
-/// the RDTSCP instruction forces serialization of code execution in the CPU.
-/// Intel recommends the usage of the RDTSCP instruction for precision timing:
-/// https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/ia-32-ia-64-benchmark-code-execution-paper.pdf
-///
-/// Inline assembly MUST NOT be used because the compiler won't be aware that
-/// certain registers are being overwritten by the RDTSCP instruction. That is
-/// why we use the builtin command.
