Public Types
enum class Kind { NoFormat, Unsigned, Signed, HexUpper, HexLower }

Evaluates a format to true if it can be used in a match.

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.

Definition at line 39 of file FileCheckImpl.h.

◆ Kind

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 ( APInt Value ) const

Returns

the string representation of [Value](classllvm%5F1%5F1Value.html "LLVM Value Representation.") in the format represented by this instance, or an error if conversion to this format failed or the format is NoFormat.
