[LLVMdev] Improving loop vectorizer support for loops with a volatile iteration variable
Hi all,
I would like to propose an improvement of the “almost dead” block
elimination in Transforms/Local.cpp so that it will preserve the canonical
loop form for loops with a volatile iteration variable.
*** Problem statement
Nested loops in LCALS Subset B (https://codesign.llnl.gov/LCALS.php) are
not vectorized with LLVM -O3 because the LLVM loop vectorizer fails the
test whether the loop
