Function Documentation

◆ extractArrayRefElementType()

mlir::StringRef extractArrayRefElementType ( mlir::StringRef cppType )

inline

Extract element type from ArrayRef<...>

Definition at line 197 of file CommonCAPIGen.h.

◆ isAPIntType()

bool isAPIntType ( mlir::StringRef cppType )

inline

Check if a C++ type is APInt.

Parameters

cppType The C++ type string to check

Returns: true if the type is APInt, llvm::APInt, or ::llvm::APInt

Definition at line 181 of file CommonCAPIGen.h.

◆ isArrayRefType()

bool isArrayRefType ( mlir::StringRef cppType )

inline

Check if a C++ type is an ArrayRef type.

Parameters

cppType The C++ type string to check

Returns: true if the type is ArrayRef, llvm::ArrayRef, or ::llvm::ArrayRef

Definition at line 190 of file CommonCAPIGen.h.

◆ isCppLanguageConstruct()

bool isCppLanguageConstruct ( mlir::StringRef methodName )

inline

Check if a method name represents a C++ control flow keyword or language construct.

Parameters

methodName The method name to check

Returns: true if the name is a C++ language construct (if, for, while, etc.)

Definition at line 162 of file CommonCAPIGen.h.

◆ isCppModifierKeyword()

bool isCppModifierKeyword ( mlir::StringRef tokenText )

inline

Check if a token text represents a C++ modifier/specifier keyword.

Parameters

tokenText The token to check

Returns: true if the token is a C++ modifier (inline, static, virtual, etc.)

Definition at line 145 of file CommonCAPIGen.h.

◆ isIntegerType()

bool isIntegerType ( mlir::StringRef type )

inline

Check if a C++ type is a known integer type.

Parameters

type	The type string to check

Returns: true if the type is an integer type (size_t, unsigned, int*, uint*, etc.)

Definition at line 100 of file CommonCAPIGen.h.

◆ isPrimitiveType()

bool isPrimitiveType ( mlir::StringRef cppType )

inline

Check if a C++ type is a known primitive type.

Parameters

cppType The C++ type string to check

Returns: true if the type is a primitive (bool, void, int, etc.)

Note: This function must be called on the CPP type because after converting to CAPI type, some things like APInt become primitive which can lead to missing wrap/unwrap functions.

Definition at line 136 of file CommonCAPIGen.h.

◆ mapCppTypeToCapiType()

std::string mapCppTypeToCapiType ( mlir::StringRef cppType )

Map C++ type to corresponding C API type.

Parameters

cppType The C++ type to map

Returns: The corresponding C API type string

Note: This function should not be called directly for ArrayRef types. Use extractArrayRefElementType() first and then use this on the result.

◆ matchesMLIRClass()

bool matchesMLIRClass	(	mlir::StringRef	cppType,
		mlir::StringRef	typeName )

Check if a C++ type matches an MLIR type pattern.

Parameters

cppType	The C++ type to check
typeName	The MLIR type name to match against

Returns: true if the C++ type matches the MLIR type

◆ parseExtraMethods()

llvm::SmallVector< ExtraMethod > parseExtraMethods ( mlir::StringRef extraDecl )

Parse method declarations from an extraClassDeclaration using Clang's Lexer.

Parameters

extraDecl The C++ code from an extraClassDeclaration

Returns: Vector of parsed method signatures

This function parses C++ method declarations to extract signatures that can be wrapped in C API functions. It identifies methods by looking for the pattern: [modifiers] <return_type> <identifier> '(' [params] ')' [const] ';'

Example input:

unsigned getWidth() const;
bool isSignless() const;

Example output:

ExtraMethod { returnType="unsigned", methodName="getWidth", documentation="Get the width of this type", isConst=true, hasParameters=false, parameters={} }
ExtraMethod { returnType="bool", methodName="isSignless", documentation="", isConst=true, hasParameters=false, parameters={} }

◆ toPascalCase()

std::string toPascalCase ( mlir::StringRef str )

inline

Convert names separated by underscore or colon to PascalCase.

Parameters

str	The input string to convert (may contain underscores or colons)

Returns: The converted PascalCase string

Examples: "no_inline" -> "NoInline" "::llzk::boolean::Type" -> "LlzkBooleanType"

Definition at line 75 of file CommonCAPIGen.h.

◆ tryCppTypeToCapiType()

std::optional< std::string > tryCppTypeToCapiType ( mlir::StringRef cppType )

Convert C++ type to MLIR C API type.

Parameters

cppType The C++ type to convert

Returns: The corresponding MLIR C API type if convertible, std::nullopt otherwise

◆ warnSkipped()

template<typename S>

void warnSkipped	(	const S &	methodName,
		const std::string &	message )

inline

Print warning about skipping a function.

Definition at line 30 of file CommonCAPIGen.h.

◆ warnSkippedNoConversion()

template<typename S>

void warnSkippedNoConversion	(	const S &	methodName,
		const std::string &	cppType )

inline

Print warning about skipping a function due to no conversion of C++ type to C API type.

Definition at line 38 of file CommonCAPIGen.h.
