This class implements the register bank concept.
Two instances of RegisterBank must have different ID. This property is enforced by the RegisterBankInfo class.

| bool RegisterBank::covers | ( | const TargetRegisterClass & | RC | ) | const |
Check whether this register bank covers RC.
In other words, check if this register bank fully covers the registers that RC contains.

| LLVM_DUMP_METHOD void RegisterBank::dump | ( | const TargetRegisterInfo * | TRI = nullptr | ) | const |
Dump the register mask on dbgs() stream.
The dump is verbose.

Get a user friendly name of this register bank.
Should be used only for debugging purposes.

| void RegisterBank::print | ( | raw_ostream & | OS, |

| ) | const |
Print the register mask on OS.
If IsForDebug is false, then only the name of the register bank is printed. Otherwise, all the fields are printing. TRI is then used to print the name of the register classes that this register bank covers.

Check if this register bank is valid.
In other words, if it has been properly constructed.
