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.

Member Function Documentation

◆ getMatchingString()

Expected< std::string > ExpressionFormat::getMatchingString ( APInt  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.

Definition at line 48 of file FileCheck.cpp.

References llvm::createStringError(), HexLower, HexUpper, Signed, and Unsigned.

◆ operator bool()

llvm::ExpressionFormat::operator bool ( ) const
inlineexplicit

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

◆ operator!=() [1/2]

bool llvm::ExpressionFormat::operator!= ( const ExpressionFormat Other) const

◆ operator!=() [2/2]

bool llvm::ExpressionFormat::operator!= ( Kind  OtherValue) const
inline

Definition at line 76 of file FileCheckImpl.h.

◆ operator==() [1/2]

bool llvm::ExpressionFormat::operator== ( const ExpressionFormat Other) const

◆ operator==() [2/2]

bool llvm::ExpressionFormat::operator== ( Kind  OtherValue) const
inline

Definition at line 74 of file FileCheckImpl.h.

◆ toString()

StringRef ExpressionFormat::toString ( ) const
Returns
the format specifier corresponding to this format as a string.

Definition at line 32 of file FileCheck.cpp.

References HexLower, HexUpper, llvm_unreachable, NoFormat, Signed, and Unsigned.

◆ valueFromStringRepr()

APInt 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.
