similar to: llvm cross compilation issue

I need to build libLLVM (individual static libraries are fine at the moment) using mingw-w64 cross compilers, i686-w64-mingw32-gcc and (separately) x86_64-w64-mingw32-gcc. I'd like this to work from both Linux and Cygwin build environments. With autotools, this worked fine: ../configure --host=i686-w64-mingw32 and that's it (with mingw32-gcc-c++ installed on Fedora 23, also works fine on

Would you mind tweaking Android.cmake so that I can override the location of the C compiler? The current version forces me to use the just-built-clang and that the new build directory be in a sibling directory.

Okay, dropping gcc 4.4.3 makes sense. How do you feel about using clang 3.2 (and the upcoming 3.3) instead of tip-of-the-trunk clang? It looks like everything works great, but that you just need to make those UB tests 'unsupported' since they fail with "libclang_rt.ubsan was built without __int128 support".

I'm an idiot and sent to llvm-commits instead of llvm-dev. Fixing.

I think this issue is that we were not using the INTERCEPTOR macros to define these functions. The following patch seems to work for me to get the build linking again, however, I cannot test -- when I run check-asan, I get: 2> lit.py: lit.common.cfg:59: fatal: Invalid llvm_tools_dir config attribute: 'E:/llvm/2013/$(Configuration)/bin' ~Aaron On Thu, Oct 23, 2014 at 1:20 PM, Aaron

Hello, I have a working GCC toolchain and wanted to use LLVM tooling instead. Following the instructions on the website I set up my build directory and have lld as an internal project under tools/. I'd like to make use of lld in stage 2 of the build and thought -DLLVM_ENABLE_LLD was the correct option to pass. However, adding this options makes the configure step fail, complaining that the

A few days ago, I tried to change the optimization flag from -O0 to -O2 to speed up the execution of the application on Ubuntu/ARM 14.04 32 bit. When I compiled the source code with -O2 flag instead of -O0 flag, I could not run the application normally by getting always the segmentation fault. Here is debugging information with GDB command in case of that. As you can see, we could not execute

(kcc, george: sorry for the re-send, the first was from a non-list email address) My configuration for building the fuzzers in the LLVM tree doesn't seem to work any more (possibly as of moving libFuzzer to compiler-rt, but there have been a few other changes in the last week or so that may be related). I'm building with a fresh top-of-tree clang and setting -DLLVM_USE_SANITIZER=Address

I can replicate the problem on Linux with mkdir foo && cd foo cmake -DLLVM_TARGETS_TO_BUILD=X86 ../llvm I'll investigate a bit.
