But does not gives same information... You'd like to change output of -instruction-tables? 
-scheduling-info should be used by llvm developer and -instruction-tables by application developer.

-scheduling-info output:
`Scheduling Info:`
`[1]: #uOps`
`[2]: Latency`
`[3]: Bypass Latency`
`[4]: Throughput`
`[5]: Resources`
`[6]: LLVM OpcodeName`
`[1]    [2]  [3]   [4]      [5]                   [6]           Instructions:`
` 1      5    2     2.00     V1UnitV,V1UnitV01     BFMLALB_ZZZ   bfmlalb       z0.s, z1.h, z2.h`

-instruction-tables output:
`Instruction Info:`
`[1]: #uOps`
`[2]: Latency`
`[3]: RThroughput`
`[4]: MayLoad`
`[5]: MayStore`
`[6]: HasSideEffects (U)`
`[1]    [2]    [3]    [4]    [5]    [6]    Instructions:`
