similar to: [LLVMdev] How to use clang -intergrated-as to compile cross-(os/target) assembly file.

I don't think we should attempt to mangle symbols declared in assembly source files. If you're writing assembly, you will need to handle ABI portability, including the _ prefix on win32 x86. clang will run the C preprocessor for you if you use the .S file suffix (case matters).

I'm so close to having LLVM build on PowerPC. If there's any PowerPC experts, help? Lines like this: outs() << "[" << format("%2d", i) << "]" << "(sec " << format("%2d", int16_t(symbol->SectionNumber)) << ")" << "(fl 0x" <<

I found that access llvm-mc from clang driver is impossible, and I want to use llvm-mc to compile assembly files, how to do that?

Does this give correct results for special floats (0, infs)? We tried to improve (for single floats) x86 rcp in llvmpipe with newton-raphson, but unfortunately not being able to give correct results for these two cases (without even more additional code) meant it got all disabled in the end (you can still see that code in the driver) since the problems are at least as bad as those due to bad

This is parallel to the pre-SM50 change which does this. Adjusts the shuffles / quadops to make the values correct relative to lane 0, and then splat the results to all lanes for the final move into the target register.

Unfortuantely we don't know if a particular load is a real 2d image (as would be a cube face or 2d array element), or a layer of a 3d image. Since we pass in the TIC reference, the instruction's type has to match what's in the TIC (experimentally). In order to properly support bindless images, this also can't be done by looking at the current bindings and generating appropriate

Retrieving the high 32 bits of a signed multiply is rather annoying. It appears that the simplest way to do this is to compute the absolute value of the arguments, and perform a u32 x u32 -> u64 operation. If the arguments' signs differ, then negate the result. Since there is no u64 support in the cvt instruction, we have the perform the 2's complement negation "by hand".

Alpine linux is a distribution that uses musl libc instead glibc. Here are my steps to reproduce: On Alpine linux, download LLVM, Clang, LLD 6.0.0 from releases.llvm.org, and build them from source. $ clang -c hello_world.c $ ld.lld --gc-sections -m elf_x86_64 -o hello_world /usr/lib/gcc/x86_64-alpine-linux-musl/6.4.0/../../../../lib/Scrt1.o

I have managed to compile llvm and clang against musl, but it behaves really strange: At first I tried to launch the compiler with musl dynamic loader: $ LD_LIBRARY_PATH=/path/to/musl/lib /path/to/musl/lib/ld-musl-x86_64.so.1 /path/to/llvm/bin/clang -v clang version 4.0.0 (https://github.com/llvm-mirror/clang 40adebeca0f99006d407508653c2cbd270a1a51c) (https://github.com/llvm-mirror/llvm

Can you add `--reproduce=repro` to lld command line? That generates repro.tar in your current directory which contains all input files. And then please compress and upload it somewhere so that we can take a look.

After re-cmaking and rebuilding everything from scratch, I'm seeing failures in MCJIT. It this something known or expected? I build LLVM/clang with pre-packaged clang-3.7.0, with "-stdlib=libc++". Example failure: /w/bld/org/./bin/lli -remote-mcjit -mcjit-remote-process=/w/bld/org/./bin/lli-child-target /w/src/llvm.org/test/ExecutionEngine/MCJIT/remote/eh.ll -- Exit Code:

Hi Lang, I am on Ubuntu 14.04. I am building ToT: llvm, clang, polly, lld, compiler-rt, libcxx, libcxxabi. The build compiler is: clang+llvm-3.7.0-x86_64-linux-gnu-ubuntu-14.04 The failures show up during "make check-all". My cmake command was: cmake -G 'Unix Makefiles' -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/w/c/org -DLLVM_TARGETS_TO_BUILD:STRING=all
