libc for the AArch64 target support

Hi,
I am wondering if the community has been through or still working on
the libc port to AArch64.

On ThunderX2 I am trying to build the project together with others, but
it is slow and not sure if the build was a success.

Realistically, the libc project just started. Barring few examples
showcasing how we want to build this libc, there isn't much available.
However, if you are on Linux, you should be able to build what is
present. The libc itself will not take very long to build. Can you
try:

$> cmake ../llvm -G Ninja -DLLVM_ENABLE_PROJECTS="libc;llvm"
$> ninja llvmlibc

Thanks,
Siva Chandra

Is there a Ninja target like

ninja check-llvmlibc

?

Is there a Ninja target like

ninja check-llvmlibc

Not yet. We have a target libc_string_unittests. I will very soon add
targets like check-llvmlibc etc.
