Does anyone have any experience of what can be profiled in the profiled guided optimisations?<br><br>One of the problems with some of the string routines is that you can write pretty neat fast routines that<br>work well for long strings - but most of the calls actually pass short strings and the overhead of the<br>
fast routine means that for most cases you are slower than you would have been with a simple routine.<br><br>If Profile Guiding could spot that a particular callsite to say strlen() was often associated with strings<br>of at least &#39;n&#39; characters we could call a different implementation.<br>
