Hi, I'm getting a "random" build failure related to AArch64 when building with cmake. The build is running with -j32 so it seems that there is some dependency issue that causes the build to fail when things build in a certain order. Is anyone else seeing this problem? paul 3008 make[2]: *** No rule to make target `lib/Target/AArch64/AArch64GenDAGISel.inc', needed by `lib/Target/AArch64/Utils/CMakeFiles/LLV...

Note that I had two other processes running, so 2 cores were unavailable throughout the -j32 build. I did not use CMake but the standard autoconf + Makefile build.

CMake introduces more parallelism and it would be great to see how much impact it makes. If you can, please run the cmake build with -j32, just to compare with the `make' build. If you simply ran `configure && time make' for the autoconf build, that builds the Debug+Asserts mode. For replicating it on cmake, run mkdir build-directory && cd build-directory cmake -DCMAKE_BUILD_TYPE=Debug path/to/llvm/source/ro...

So I just started looking into LLVM and I was wondering how to install the LLVM tools suite. (Such as the llvm-as or lli commands in the terminal described here: http://llvm.org/docs/CommandGuide (http://llvm.org/docs/CommandGuide/)). I have downloaded LLVM, Clang, the test suite, and have run the build and make commands. I have looked around on the website but I have not found a sufficient
