Option becomes: -instruction-tables=`<level>`
The choice of `<level>` controls number of printed information.
`<level>` may be `none` (default), `normal`, `full`.
Note: If the option is used without `<label>`, default is `normal`
(legacy).
When `<level>` is `full`, additional information are:
- `<Bypass Latency>`: Latency when a bypass is implemented between
operands
in pipelines (see SchedReadAdvance).
- `<LLVM Opcode Name>`: mnemonic plus operands identifier.
- `<Resources units>`: Used resources associated with LLVM Opcode.
- `<instruction comment>`: reports comment if any from source assembly.
Level `full` can be used to better check scheduling info when TableGen
is modified.
LLVM Opcode name help to find right instruction regexp to fix TableGen
Scheduling Info.
-instruction-tables=full option is validated on
AArch64/Neoverse/V1-sve-instructions.s
