[PATCH] D131757: [instcombine] Test for zero initialisation optimisation of a product given fast flags

[Florian Hahn via Phabricator via llvm-commits]

fhahn added inline comments.


================
Comment at: llvm/test/Transforms/InstCombine/remove-loop-phi-fastmul.ll:233
+  %i.02 = phi i64 [ 0, %entry ], [0, %entry_2], [ %inc, %for.body ]
+  %f_prod.01 = phi double [ 0.0, %entry ], [0.0, %entry_2], [ %mul, %for.body ]
+  %arrayidx = getelementptr inbounds [1000 x double], ptr %arr_d, i64 0, i64 %i.02
----------------
might be good to also have a variant of this test that doesn't have 0.0 as incoming value.
