◆ classof()

static bool circt::firrtl::FIRRTLBaseType::classof ( Type type )

inlinestatic

Support method to enable LLVM-style type casting.

Definition at line 185 of file FIRRTLTypes.h.

◆ getAllConstDroppedType()

FIRRTLBaseType FIRRTLBaseType::getAllConstDroppedType ( )

Return this type with a 'const' modifiers dropped.

Definition at line 723 of file FIRRTLTypes.cpp.

Referenced by convertType(), and inferMuxReturnType().

◆ getAnonymousType()

FIRRTLBaseType FIRRTLBaseType::getAnonymousType ( )

Return this type with any type alias types recursively removed from itself.

Return this type with any type aliases recursively removed from itself.

Definition at line 685 of file FIRRTLTypes.cpp.

Referenced by circt::firrtl::areAnonymousTypesEquivalent().

◆ getBitWidthOrSentinel()

int32_t FIRRTLBaseType::getBitWidthOrSentinel ( )

If this is an IntType, AnalogType, or sugar type for a single bit (Clock, Reset, etc) then return the bitwidth.

Return -1 if the is one of these types but without a specified bitwidth. Return -2 if this isn't a simple type.

◆ getConstType()

FIRRTLBaseType FIRRTLBaseType::getConstType ( bool isConst )

Return a 'const' or non-'const' version of this type.

Definition at line 711 of file FIRRTLTypes.cpp.

References isConst().

Referenced by createZeroValue(), inferMuxReturnType(), and updateType().

◆ getMaskType()

FIRRTLBaseType FIRRTLBaseType::getMaskType ( )

Return this type with all ground types replaced with UInt<1>.

This is used for mem operations.

Definition at line 737 of file FIRRTLTypes.cpp.

References isConst().

◆ getPassiveType()

FIRRTLBaseType FIRRTLBaseType::getPassiveType ( )

Return this type with any flip types recursively removed from itself.

Referenced by circt::firrtl::isTypeLarger().

◆ getWidthlessType()

FIRRTLBaseType FIRRTLBaseType::getWidthlessType ( )

Return this type with widths of all ground types removed.

Remove the widths from this type.

This enables two types to be compared by structure and name ignoring widths.

All widths are replaced with an unknown width.

◆ isPassive()

bool circt::firrtl::FIRRTLBaseType::isPassive ( ) const

inline

Return true if this is a "passive" type - one that contains no "flip" types recursively within itself.

Definition at line 154 of file FIRRTLTypes.h.

Referenced by isConstFieldDriven(), and isRegisterType().

◆ isRegisterType()

bool circt::firrtl::FIRRTLBaseType::isRegisterType ( )

inline

Returns true if this is a non-const "passive" that which is not analog.

Definition at line 192 of file FIRRTLTypes.h.

References circt::firrtl::containsConst(), and isPassive().

◆ isResetType()

bool FIRRTLBaseType::isResetType ( )

Return true if this is a valid "reset" type.

Return true if this is a type usable as a reset.

This must be either an abstract reset, a concrete 1-bit UInt, an asynchronous reset, or an uninfered width UInt.
