[PATCH] D75662: [MLIR] add negi in standard dialect

[Alex Zinenko via Phabricator via llvm-commits]

ftynse added a comment.

I think integer negation is always okay being implemented as "0 - x" (the only dangerous case is signed INT_MIN, but negating it leads to overflow in any case). This isn't the case for floating point numbers because of special values (nan/inf) and normalization, so it needs an instruction.
