I've just discovered how immature LLVM/Clang was on ARM.
In the benchmark results posted above there doesn't seem to be much difference between C
and Rust
on x86_64
, however on my ARM
system it's like:
gcc's 1.5s
to rust's (or clang's 3.6) 3.4s
meaning the newer llvm 3.7
bundled with rust makes no difference.
