◆ parseType()

Type mlir::LLVM::detail::parseType ( DialectAsmParser parser)

Parses an LLVM dialect type.

Parses one of the LLVM dialect types.

◆ printType()

void mlir::LLVM::detail::printType ( Type  type,
AsmPrinter printer 
)

Prints an LLVM Dialect type.

Prints the given LLVM dialect type recursively.

This leverages closedness of the LLVM dialect type system to avoid printing the dialect prefix repeatedly. For recursive structures, only prints the name of the structure when printing a self-reference. Note that this does not apply to sibling references. For example, struct<"a", (ptr<struct<"a">>)> struct<"c", (ptr<struct<"b", (ptr<struct<"c">>)>>, ptr<struct<"b", (ptr<struct<"c">>)>>)> note that "b" is printed twice.
