Detailed Description

Type representing the format an expression value should be textualized into for matching.

Used to represent both explicit format specifiers as well as implicit format from using numeric variables.

Member Enumeration Documentation

Kind

enum class llvm::ExpressionFormat::Kind

strong

Enumerator
NoFormat	Denote absence of format. Used for implicit format of literals and empty expressions.
Unsigned	Value is an unsigned integer and should be printed as a decimal number.
Signed	Value is a signed integer and should be printed as a decimal number.
HexUpper	Value should be printed as an uppercase hex number.
HexLower	Value should be printed as a lowercase hex number.

getMatchingString()

Expected< std::string > ExpressionFormat::getMatchingString

(

ExpressionValue

Value

const

Returns

the string representation of Value in the format represented by this instance, or an error if conversion to this format failed or the format is NoFormat.

getWildcardRegex()

Expected< std::string > ExpressionFormat::getWildcardRegex

)

const

Returns

a wildcard regular expression string that matches any value in the format represented by this instance and no other value, or an error if the format is NoFormat.

valueFromStringRepr()

Expected< ExpressionValue > ExpressionFormat::valueFromStringRepr	(	StringRef	StrVal,
		const SourceMgr &	SM
	)		const

Returns

the value corresponding to string representation StrVal according to the matching format represented by this instance or an error with diagnostic against SM if StrVal does not correspond to a valid and representable value.
