llvm is illegally vectorizing with a recurrence on skylake
...ent inlining of one()), it correctly prevents vectorization.
clang -S -O2 -Rpass=loop-vectorize -Rpass-missed=loop-vectorize small.c
-march=skylake-avx512 -DNO_TWO
small.c:6:3: remark: loop not vectorized [-Rpass-missed=loop-vectorize]
do {
I did trace it down to possibly being something within
