Public bug reported:
llvm-toolchain-11 is FTBFS'ing with Linux 5.13 because of:

This is happening because the Cyclades driver has been finally removed
from Linux (after being orphaned 13 years ago):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/include/uapi/linux?h=v5.12&id=f76edd8f7ce06cdff2fe5b6b39a49644c684a161
LLVM includes cyclades.h when building libsanitizer, and therefore the
FTBFS occurs.
Upstream has fixed this by removing support for Cyclades from
libsanitizer:
https://github.com/llvm/llvm-
project/commit/884040db086936107ec81656aa5b4c607235fb9a
As for the GCC 11 failure, the problem is:

kmax
/<<PKGBUILDDIR>>/llvm/utils/benchmark/src/benchmark_register.h:17:18: note:
'kmax' declared here
static const T kmax = std::numeric_limits<T>::max();
This comes from the fact that GCC 11 requires the inclusion of the
<limits> header in order to access std::numeric_limits<T>. This has
also been fixed upstream:
https://github.com/llvm/llvm-
project/commit/b498303066a63a203d24f739b2d2e0e56dca70d1
I'm preparing and testing a patch, and will attach it to this bug soon.
