search for: schedgraph

I want to create a simple map from a Value to the instruction that defines it. Such a map is present inside SchedGraph, but I need it in a much simpler context. If I got it right, I create a new AnalysisGroup, and write a pass that implements it. What kind of pass should I derive it from? The mapping only makes sense within a function, so FunctionPass seems to be the right choice ... is that correct? The document...

...crazy testing out different options... At the end, unmangling the differences in what linker was searching and what was present in the libraries, I found that the problem is that we have something like this... Value.h struct Value { bla bla bla } and around in the other files: SlotCalculator.h SchedGraph.h <big snip> class Value; The linker complains about the different parameters types, and raise an unresolved external symbol. I can resolve the iussue a) turning the original struct Value { ... } in class Value { public: .... } b) turning all the class Value; into struct Value; The same...

I just updated to RELENG_7 from 6.2 and I'm running into some really annoying issues with jerky mouse movement and skipping sound. This seems to be similar to: Re: SCHED_4BSD in RELENG_7 disturbs workflow This happens both with 4BSD and ULE. I seems to happen when I'm compiling ports and a new cc/bzip2/sh process fires off (I'm just watching top), I'll get the skip/freezeup.

> What specific information do you need? All my experiments eventually analyze or transform the data dependence graph, which takes into account both registers and aliasing information. Because there is already a built-in support for graphs, I hoped there is also built-in support for data dependence graphs. That would allow, for example, to display them naturally with dot utility.
