generatedTypeParser()

static

These are unused for now.

getPointerDataLayoutEntry()

static std::optional<uint64_t> getPointerDataLayoutEntry ( DataLayoutEntryListRef  params, LLVMPointerType  type, PtrDLEntryPos  pos  )

static

Returns the part of the data layout entry that corresponds to pos for the given type by interpreting the list of entries params.

For the pointer type in the default address space, returns the default value if the entries do not provide a custom one, for other address spaces returns std::nullopt.

parseExtTypeParams()

static ParseResult parseExtTypeParams ( AsmParser &  p, SmallVectorImpl< Type > &  typeParams, SmallVectorImpl< unsigned int > &  intParams  )

static

Parses the parameter list for a target extension type.

The parameter list contains an optional list of type parameters, followed by an optional list of integer parameters. Type and integer parameters cannot be interleaved in the list. extTypeParams ::= typeList? | intList? | (typeList "," intList) typeList ::= type ("," type)* intList ::= integer ("," integer)*
