This file implements the StringSwitch template, which mimics a switch() statement whose cases are str...

StringRef - Represent a constant reference to a string, i.e.

std::pair< StringRef, StringRef > split(char Separator) const

Split into two substrings around the first occurrence of a separator character.

constexpr bool empty() const

empty - Check if the string is empty.

A switch()-like statement whose cases are string literals.

StringSwitch & Case(StringLiteral S, T Value)

StringSwitch & Cases(std::initializer_list< StringLiteral > CaseStrings, T Value)

This class implements an extremely fast bulk output stream that can only output to a stream.

A raw_ostream that writes to an std::string.

This is an optimization pass for GlobalISel generic memory operations.

DenormalMode::DenormalModeKind parseDenormalFPAttributeComponent(StringRef Str)

Parse the expected names from the denormal-fp-math attribute.

LLVM_ABI FPClassTest fneg(FPClassTest Mask)

Return the test mask which returns true if the value's sign bit is flipped.
