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 in...

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

...ease_interface() often caused my driver process to go into uninterruptible sleep and never wake up (it could not even be killed with "kill -KILL"). I had to reboot each time to be able to attach another driver. I commented out this call, which seems to be useless anyway. 4) nut-cvs-patch-NUMPATH-2005-08-24 ---------------------------------------- This patch extends the function hid_lookup_usage() so that path names can also be looked up by numerical values. This is just a convenience - it allows one to put stuff like "UPS.PowerConverter.ff860024" in the apc-hid.h while testing d...
