Hi, The test-suite expects to be built standalone but it looks like you have it in the same tree as LLVM. You'll need to remove it.

With reference to the following thread: http://lists.llvm.org/pipermail/llvm-dev/2016-January/094100.html I am having the same issue. First I did a git pull of all the relevant directories and then doing a cmake: cmake -DLLVM_ENABLE_DOXYGEN=ON -DLLVM_ENABLE_WERROR=OFF -DLLVM_TARGETS_TO_BUILD="X86" ../llvm and followed by make: [ 22%] Built target LLVMVectorize [ 25%] Built target

I think we've just forgotten to update that part of the instructions. Having the test-suite at projects/test-suite was harmless to the old autoconf and LLVM 3.7.x's cmake builds because it didn't actually cause the test-suite to be built. The CMakeLists.txt that have been added to the test-suite now cause it to be built by LLVM's build system which introduces the build failure. We

Hi, cross-compiling LLVM on the ppc64 architecture fails with: make[1]: *** No rule to make target `../build/llvm-r204075/BuildTools/Debug+Asserts/bin/llvm-tblgen', needed by `../build/llvm-r204075/lib/IR/Debug+Asserts/Intrinsics.gen.tmp'. Stop. make[1]: *** Waiting for unfinished jobs.... this fails for me for r204075 (today) and r203443. Configuration details: $LLVMPATH/configure

Hi, I am new to LLVM and I find TableGen language really cryptic. The reference manual to the language is not helpful either. I can look at the existing .td file and reverse engineer but I am looking for a detailed manual. Specifically, I have below questions: 1. What is a basic syntax for writing a dag? From the lang ref manual I can see that its something like operator followed by ArgList which

Hi all, my name is Elior Malul, and Intel employee, and it is the first time I'm writing to the llvm-dev community. The purpose of that mail is a 'recon-mission' on a small tblgen feature I think might prove itself useful. I would like to add a built-in types 'pair'. Pair is a compound type with two template argument: pair<ty1, ty2>; The idea is to add a literal for that

My platform is RedHat Enterprise 5, as shown below: [wuxi at ppidellsc1420 lib]$ uname -a Linux ppidellsc1420 2.6.18-8.el5 #1 SMP Fri Jan 26 14:15:21 EST 2007 i686 i686 i386 GNU/Linux and I install gcc-4.2.3, as shown below: [wuxi at ppidellsc1420 lib]$ g++ -v Using built-in specs.

Oh, so it looks like I hit a bit of a wall there :-) I’ll take a look thanks. That bug talks about R_ARM_THM_CALL which I assume are thumb related.

Very interesting, thanks! 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

I've successfully used Peter's patches to get past those relocation errors.

The bottom of the bug has the revision numbers (e.g. D34035). That one corresponds to e.g. https://reviews.llvm.org/D34035 There's also https://reviews.llvm.org/D34634 which contains all of Peter's patches, but it's not going to rebase cleanly once the individual patches start going in.
