...sure. Could this be pointing to something I'm doing wrong in my LLVM setup, or is it just slow? I'm reasonably certain I'm compiling LLVM in optimized mode, but for reference, this is my build line:     cmake .. -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_EH=ON -DLLVM_ENABLE_RTTI=ON -DLLVM_REQUIRES_RTTI=ON -DLLVM_ENABLE_CXX1Y=ON -DLLVM_LINK_LLVM_DYLIB=ON -DLLVM_ENABLE_FFI=ON -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_OPTIMIZED_TABLEGEN=ON -DCMAKE_INSTALL_PREFIX="/opt/llvm/install" The overall time split, from valgrind, between shared libraries in my code is:     80.48%, libLLVM-6.0.so     8.8...

...can try building LLVM with CXXFLAGS=-frtti configure .... CXXFLAGS=-frtti make ... I'm not sure if CXXFLAGS takes precedence over the hard-coded -fno-rtti in the makefiles, though. With the cmake build, you can try as above (but replacing `configure' with `cmake') or, better: cmake -DLLVM_REQUIRES_RTTI=ON ... rest of cmake args ... Adding an option for enabling RTTI on the cmake build is trivial. Dunno about the `configure' build. You can try filing a feature request on Bugzilla.

Hi Fellows, The goal is to find the induction variable for a loop, where the induction variable increments with the multiplication, division or shift operations, like this one: sz = 8; do { ... ... sz = sz / 2; } while (sz) Is SCEV capable of detecting the induction variable 'sz' in this case? The code snippet I am using to solve the problem is for each basic-block in a

Hi all, I am having some some trouble with LLVM 3.8... I built it with GCC 4.8.2 with cmake and no special CXX/C flags. That means in case of GCC that RTTI is switched on, I believe. However, building my MCJIT application against the just built LLVM and linking results in: libqdp.a(qdp_llvm.o):(.rodata._ZTIN4llvm8FCmpInstE[_ZTIN4llvm8FCmpInstE]+0x10): undefined reference to `typeinfo for
