The code is organized into 3 parts (2 passes) 1) a linked set of profiling passes, which implement an analysis group (linked, like alias analysis are). These insert profiling into the program, and remember what they inserted, so that at a later time they can be queried about any instruction. 2) a pass that handles inserting the random sampling framework. This also has options to control how random samples are choosen. Currently implemented are Global counters, register allocated global counters, and read cycle counter (see? there was a reason for it). The profiling passes are almost identical to the existing ones (block, function, and null profiling is supported right now), and they are valid passes without the sampling framework (hence the existing passes can be unified with the new ones, not done yet). Some things are a bit ugly still, but that should be fixed up soon enough. Other todo? making the counter values not "magic 2^16 -1" values, but dynamically choosable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24493 91177308-0d34-0410-b5e6-96231b3b80d8
