2005-11-28Random sampling (aka Arnold and Ryder) profiling. This is still ↵Andrew Lenharth
preliminary, but it works on spec on x86 and alpha. The idea is to allow profiling passes to remember what profiling they inserted, then a random sampling framework is inserted which consists of duplicated basic blocks (without profiling), such that at each backedge in the program and entry into every function, the framework chooses whether to use the instrumented code or the instrumentation free code. The goal of such a framework is to make it reasonably cheap to do random sampling of very expensive profiling products (such as load-value profiling). 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

2005-11-11Add support for a cycle counter intrinsic. As basically all processors haveAndrew Lenharth
this and have it in about the same form, I think this makes sense. on X86, you do a RDTSC (64bit result, from any ring since the P5MMX) on Alpha, you do a RDCC on PPC, there is a sequence which may or may not work depending on how things are setup by the OS. Or something like that. Maybe someone who knows PPC can add support. Something about the time base register. on Sparc, you read %tick, which in some solaris versions (>=8) is readable by userspace on IA64 read ar.itc So I think the ulong is justified since all of those are 64bit. Support is slighly flaky on old chips (P5 and lower) and sometimes depends on OS (PPC, Sparc). But for modern OS/Hardware (aka this decade), we should be ok. I am still not sure what to do about lowering. I can either see a lower to 0, to gettimeofday (or the target os equivalent), or loudly complaining and refusing to continue. I am commiting an Alpha implementation. I will add the X86 implementation if I have to (I have use of it in the near future), but if someone who knows that backend (and the funky multi-register results) better wants to add it, it would take them a lot less time ;) TODO: better lowering and legalizing, and support more platforms git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24299 91177308-0d34-0410-b5e6-96231b3b80d8
