Function Documentation

◆ dispatchParse() [1/2]

static Type dispatchParse ( AsmParser parser,
bool  allowAny = true 
)
static

Parses a type appearing inside another LLVM dialect-compatible type.

This will try to parse any type in full form (including types with the !llvm prefix), and on failure fall back to parsing the short-hand version of the LLVM dialect types without the !llvm prefix.

Definition at line 300 of file LLVMTypeSyntax.cpp.

◆ dispatchParse() [2/2]

static ParseResult dispatchParse ( AsmParser parser,
Type type 
)
static

Helper to use in parse lists.

Definition at line 341 of file LLVMTypeSyntax.cpp.

◆ dispatchPrint()

static void dispatchPrint ( AsmPrinter printer,
Type  type 
)
static

If the given type is compatible with the LLVM dialect, prints it using internal functions to avoid getting a verbose !llvm prefix.

Otherwise prints it as usual.

Definition at line 26 of file LLVMTypeSyntax.cpp.

◆ getTypeKeyword()

static StringRef getTypeKeyword ( Type  type)
static

Returns the keyword to use for the given type.

Definition at line 33 of file LLVMTypeSyntax.cpp.

◆ parseStructType()

static LLVMStructType parseStructType ( AsmParser parser)
static

Parses an LLVM dialect structure type.

llvm-type ::= struct< (string-literal ,)? packed? ( llvm-type-list ) > | struct< string-literal > | struct< string-literal , opaque>

Definition at line 198 of file LLVMTypeSyntax.cpp.

◆ parseVectorType()

static Type parseVectorType ( AsmParser parser)
static

Parses an LLVM dialect vector type.

llvm-type ::= vec< ? x? integer x llvm-type > Supports both fixed and scalable vectors.

Definition at line 137 of file LLVMTypeSyntax.cpp.

◆ printStructType()

static void printStructType ( AsmPrinter printer,
LLVMStructType  type 
)
static

Prints a structure type.

Keeps track of known struct names to handle self- or mutually-referring structs without falling into infinite recursion.

Definition at line 54 of file LLVMTypeSyntax.cpp.

References mlir::LLVM::LLVMStructType::getName(), and mlir::LLVM::LLVMStructType::isIdentified().

◆ trySetStructBody()

static LLVMStructType trySetStructBody ( LLVMStructType  type,
ArrayRef< Type subtypes,
bool  isPacked,
AsmParser parser,
SMLoc  subtypesLoc 
)
static

Attempts to set the body of an identified structure type.

Reports a parsing error at subtypesLoc in case of failure.
