Hi all, I was looking at the StructRetPromotion pass this morning and noticed it doesn't look at a function's linkage at all. Since it changes the signature of the function, I would say it should only change internal functions, like ArgumentPromotion does for example. Is there some implicit check I'm missing, or should an explicit c...

On this topic, you should look at the StructRetPromotion pass (lib/Transforms/IPO/StructRetPromotion.cpp). This pass does exactly the opposite of what you propose: It transforms return pointers in the first parameter to first class returns. This pass only operates on internal functions, though, so it does not have to deal with ABI issues. If you want to...

However, I'm not sure what replaces that struct of two doubles by a single i128. I think ScalarReplAggregrates is capable of doing such packing, but it only operates on local variables, not return...

Many of you are probably wondering about the status of the 2.3 release. Unfortunately, this release has been very difficult and the list of regressions very high. The list has finally dwindled down to the following regressions: Linux/x86: SingleSource/Benchmarks/CoyoteBench/fftbench [ JIT Codegen, JIT] MultiSource/Applications/minisat/minisat [CBE] Darwin/x86:
