[PATCH] D50113: [SLC] Fix shrinking of pow()

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/test/Transforms/InstCombine/double-float-shrink-1.ll:363
+; CHECK-NEXT:    [[TMP1:%.*]] = fpext float [[POWF]] to double
+; CHECK-NEXT:    ret double [[TMP1]]
 ;
----------------
It looks like optimizeBinaryDoubleFP doesn't do all the same checks optimizeUnaryDoubleFP does?  optimizeUnaryDoubleFP intentionally chooses not to optimize operations where the result isn't truncated because the extra bits might actually be useful.
