As discussed in the PR, this patch performs the decrement of countm1
before the condition, so that the loop can have empty latch block.
The testcase from the PR then can be vectorized.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?
OK from the FE side.
[I leave it to you and Richard whether you prefer this version or the
Bool version; quoting from this PR: "Not sure if it is better this way,
or with doing assignment of the condition result into a bool and using
it later (as done in the patch for the other PR)." (Other PR = PR 53957.)]
Thanks for the patch!
