Subject: llvm-reduce: Run instruction reduction last
X-Git-Tag: upstream/17.0.6~17611
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=463ab1e07a0a15a9aa129639048e29e0f8ec4dc8;p=platform%2Fupstream%2Fllvm.git

llvm-reduce: Run instruction reduction last

With the current state of mir support, this is going to generate
a large number of verifier errors. Running the use and def
reductions first helps to mitigate the impact of this.
