[PATCH] D132261: [SLP]Do not reduce repeated values, use scalar red ops instead.

[Valeriy Dmitriev via Phabricator via llvm-commits]

I'll try to look at this closely next week (but not earlier than Monday).  Just a quick note about terminology used. The option name "slp-same-scalars-reduction" does not actually tell much about what it actually controls.
Since you basically are trying to optimize away identity operations in reduction sequences I'd suggest you to use name for option and across the code that better reflect that.
The option name could be "-slp-optimize-identity-hor-reduction-ops=true|false" for example.
