How can I tell llvm, that a branch is preferred ?
If I read the llvm language correctly, it doesn't have a way to specify
the preferred branch, correct ? I see nothing in the specs for "branch"
or "switch". And __buildin_expect does nothing, that I am sure of.
Unfortunately llvm has this knack for ordering my one most crucial part
of code exactly the opposite I want to, it does: (x86_64)
cmpq %r15, (%rax,%rdx)
