Bug ID: 39485
Summary: Flag flip for Hvx loop vectorizer broke Halide
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: Hexagon
Assignee: unassignedbugs at nondot.org
Reporter: alina.sbirlea at gmail.com
CC: llvm-bugs at lists.llvm.org
r345169 ([Hexagon] Flip hexagon-autohvx to be true by default) caused internal
Halide tests to timeout (hang or very large compile times).
I reverted the changes in r345446 and r345447.
Opening the bug to track and provide a test case (pending).
