Detailed Description

This class implements the register bank concept.

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

Member Function Documentation

◆ covers()

bool RegisterBank::covers ( const TargetRegisterClass RC) const

◆ dump()

LLVM_DUMP_METHOD void RegisterBank::dump ( const TargetRegisterInfo TRI = nullptr) const

Dump the register mask on dbgs() stream.

The dump is verbose.

Definition at line 66 of file RegisterBank.cpp.

References llvm::dbgs(), print(), and TRI.

◆ getID()

unsigned llvm::RegisterBank::getID ( ) const
inline

◆ getName()

const char * llvm::RegisterBank::getName ( ) const
inline

Get a user friendly name of this register bank.

Should be used only for debugging purposes.

◆ operator!=()

bool llvm::RegisterBank::operator!= ( const RegisterBank OtherRB) const
inline

Definition at line 66 of file RegisterBank.h.

References operator==().

◆ operator==()

bool RegisterBank::operator== ( const RegisterBank OtherRB) const

Check whether OtherRB is the same as this.

Definition at line 56 of file RegisterBank.cpp.

References assert(), and getID().

Referenced by operator!=().

◆ print()

void RegisterBank::print ( raw_ostream OS,
bool  IsForDebug = false,
const TargetRegisterInfo TRI = nullptr 
) 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.

Definition at line 71 of file RegisterBank.cpp.

References assert(), covers(), End, getID(), getName(), OS, llvm::popcount(), and TRI.

Referenced by dump(), and llvm::operator<<().

◆ verify()

bool RegisterBank::verify ( const RegisterBankInfo RBI,
const TargetRegisterInfo TRI 
) const

Check if this register bank is valid.

In other words, if it has been properly constructed.

Note
This method does not check anything when assertions are disabled.
Returns
True is the check was successful.

Definition at line 23 of file RegisterBank.cpp.
