I'm having issues of my compiler, and JIT execution, of LLVM IR being rather slow. It's accounting for the vast majority of my full compilation time.  I'm trying to figure out why this is happening, since it's becoming an impediment.  (Note: by slow I mean about 3s of time for only about 2K of my front-end code, 65K lines of LLVM-IR) Using valgrind I see some functions which seem

Are you using static linking, -DBUILD_SHARED_LIBS, or -DLLVM_LINK_LLVM_DYLIB?

Greetings! I have been building llvm-3.6.x, 3.7.1 and 3.7.2 with (glibc-2.12.1, binutils-2.24, gcc-4.9.2) almost same set if CMake flags. However while building LLVM-3.8.0 using same CMake flags I am observing projects/libcxx/include/cmath errors... ...'::signbit' has not been declared ...'::fpclassify' has not been declared ...'::isfinite' has not been declared ...

Hi, Could you share how you compile IR and which version of JIT you use (Orc, MCJIT)? Could it be that you are using interpreter instead of actual JIT? Cheers, Alex. > On 5.

[Sorry about the crosspost. Since this is a clang build question but the build is invoked from the top-level LLVM directory I'm not sure where the question should go.] I've got a clang build against libstdc++ on Linux but I would really like one built against libc++/libc++abi. In other words I'd like to rebuild clang/llvm with clang using libc++ and libc++abi on Linux. I looked at

Just to follow-up, I'm now encountering this as well. I'm doing this on Linux. It seems that when linking with the most-recently built clang, the unit tests are taking a while to complete. It's notably not using more than 1 thread, and if using `lld` I would have expected the linker to still be running in parallel. I'm doing this on a debug build, so that might help narrow it

If your cut-n-paste is accurate, you seem to be missing a closing quote for CMAKE_CXX_LINK_FLAGS. hth... don On Jul 8, 2015 2:22 AM, "David A.
