At run-time, timing values are obtained by statistical sampling. Sampling is done by probing the target program's program counter at regular intervals using operating system interrupts (programmed via profil(2) or setitimer(2) syscalls). The resulting data is not exact, rather a statistical approximation. The amount of error is usually more than one sampling period. If a value is n times the sampling period, the expected error in the value is the square root of n sampling p… WebCurrently the LLVM Compiler Infrastructure supports the pro ling of pro- grams by placing counters in the code and reading the resulting pro ling data during consecutive compilations. But these counters are placed with a na ve and ine cient algorithm that uses more counters than necessary.
