Random sampling (aka Arnold and Ryder) profiling. This is still 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.

store <4 x float> %tmp2, <4 x float> *%a

_foo:

scalars.

Add an initial hack at legalizing GlobalAddress into the appropriate nodes

on Darwin to remove smarts from the isel. This is currently disabled by

tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
needed to be added to the .td file. However, we can currently emit stuff like
this: :)
li r2, lo16(L_x$non_lazy_ptr)
lis r3, ha16(L_x$non_lazy_ptr)
lwzx r2, r3, r2
