Hello everyone:
I'm building libcxx on amd64 ubuntu 14.04 for testing cloud9, but encountered
the following fatal issue that clang caused.
The program arguments are as follows:
/home/bruce/Cloud9_Root/src/third_party/llvm-build/Release+Asserts/bin/clang
-cc1 -triple x86_64-unknown-linux-gnu -e
Since clang segfaults, it could be a bug in clang.
I am not a clang expert, but I'd suggest trying to remove some of the
compiler flags and observe if the output changes. Or you could try to
use a different version of clang/llvm. And then file a bug for clang if
you can reproduce the crash.

Hi bruce,
which version of clang are you actually using? Could you please paste output of
clang -v here?
Could you please also paste full output of clang (including reproducer files if
any)?
Thank you.

Hi,
just tested the clang eBPF backend. Very cool thing :)
But I've noticed that the codegen creates really odd things which I
cannot explain from my understanding of the ISA. My test is attached
and was compiled via:
clang -O2 -target bpf -x c -c ebpf_opimizer_problems.o -o
ebpf_opimizer_probl

First thing is the odd way how 8 bit loads to an uint8_t are handled

Looks like AVR is experimental, so you'll need to pass it via

As for the correct --target, you can take a look at the logic in
llvm/cmake/config.guess to get an idea on how to construct one.

Ok, thank
