In practice we find that they fit in 64-bit wide counters are enough for numbering paths within a routine. The amount of instrumentation required is not exponential. For example, every if-condition in a routine will increase the number of paths by X2, but the ins...

This proposal adds support for path profiling [Ball96] to LLVM. Path profiling compactly represents acyclic paths in a directed acyclic graph representation of the control flow graph of a routine. Instrumentation can be added to uniquely identify paths executed at runtime. Path profiles enable precise enumeration of the sequence of basic blocks executed in order for a particular path. Using path

Is it possible to add lines or other user defined graphics to a plot in R that does not depend on the user scale for the plot? For example I have a plot plot(x,y) and I want to add some graphic that is scaled in inches or cm but I do not want the graphic to change when the x-y scales are changed - like a thermometer, scale bar or other symbol - How does one do this? I want to build my own

Hi Peter, I've forwarded your mail to upsdev as it will be of interest for several people that are working on it. As I'm also on vacation (again) for a week and 1/2 as of this evening, I don't think I'll have the time for it before I get back.... I've not yet audited the patches, but these are queued on the Alioth tracker:
