libc++ cross-compile linux-armv7 and math function problems
Hello Dimitry and thanks for your answer.
I am pretty sure it does indeed support long double. It's configured with
vfpv3-d16 - but I noticed that c++config.h in gcc has _GLIBCXX__HAS_FABSL
and friends are undefined. I think I need to look deeper at the
configuration of our toolchain.
long double support is required in libc++ then I gather?

[LLVMdev] Can libc++ build for arm cross compiler?
Hi cschen,
It seems that libunwind (the one included in libcxxabi) is mandatory at the
moment. Use the second build command instead:
$ CROSS_COMPILING=arm ENABLE_LIBUNWIND=1 ./scripts/compile-all.sh

Yeah, it would help to know more specifics about where you're getting stuck.

libcxx build error.
Hi,
I am trying to build llvm 3.4.2 on Centos 6.6. I am getting this below
build error , while building the libcxx. I followed the build procedure
based of http://clang.llvm.org/get_started.html. I cannot move to a higher
version, Since we need to develop on CentOS 6.6 and LLVM 3.4.2 ,is the
last version that supports gcc 3.4.2. Starting from LLVM 3.5.0, there has
been a huge jump to gcc 4.7.0.
I am just sta...

Hi Galina,
It seems that our libcxx bots are now triggering builds for any changes to llvm:
http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-aarch64-linux/builds/2434
Should I file a bug report for this?
Thanks,

I think what she is referring to was that the build seemed to be triggered
by a commit to a project that shouldn't trigger builds on a libcxx bot
(i.e. the change was in llvm).
I have a somewhat orthogonal but related question. In the past, commits to
compiler-rt did not trigger builds on llvm/clang/sanitizer bots. Has this
behaviour been rectified with the move to github? I am really sorry if you
already answered this question and I ju...
