Hi, All: I am trying to extend EarlyCSE.cpp to do more commoning of GEP instruction, it requires a hashtable with two keys, I defined typedef ScopedHashTable<DoubleKey, std::pair<Value *, unsigned>, DenseMapInfo<Value *>, LoadMapAllocator> LoadHTType; I declared a DoubleKey struct similar to CallValue but with two Value * member, However I have problem to implement getTombstoneKey() because I don'...

I think that extending MachineCSE to do a simple dominator tree walk with llvm::ScopedHashTable would make sense. Status register bits should be handled just like any other physreg. On x86, this is a def of EFLAGS physreg for example. On PPC, the condition code register is actually a vreg iirc. -Chris

Hi, I might just be doing something stupid, but when I do $ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-2.8 -DCMAKE_BUILD_TYPE=Release .. $ sudo make install I don't get the expected headers in /usr/local/llvm-2.8/include/llvm It is simply an empty directory. What am I doing wrong? This is on Mac OS X, CMake 2.8+ Kind regards, Samuel
