[LLVMdev] Limit loop vectorizer to SSE

[Frank Winter]

The AVX + JIT bug is hitting more frequently now. On a AVX machine the
loop vectorizer goes for a vector length of 8 for some of my functions
which in turn causes a SEGFAULT.

Is there a way to limit the loop vectorizer to a certain vector length,
say 4, such that I can work around the bug?
