Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.

Functions
LLVM_ABI void	llvm::locateAMDGPUPrintfCStrings (SparseBitVector< 8 > &BV, StringRef Fmt)
	Marks the printf arguments that the format string Fmt specifies as strings, i.e.
LLVM_ABI uint64_t	llvm::getAMDGPUPrintfFormatHash (StringRef Fmt)
	Returns the ID that buffered printf stores in place of the constant format string Fmt the low 64 bits of its MD5 hash.
LLVM_ABI std::string	llvm::getAMDGPUPrintfFormatMetadata (StringRef Fmt)
	Returns the llvm.printf.fmts entry that maps the ID of the constant format string Fmt back to the string.
LLVM_ABI void	llvm::packAMDGPUPrintfConstantString (StringRef Str, SmallVectorImpl< uint32_t > &Words)
	Splits the constant string argument Str, including its terminating NUL, into the little-endian 32-bit words that buffered printf stores for it, padded to a multiple of 8 bytes.

Variables
constexpr StringLiteral	llvm::AMDGPUPrintfNonConstFormatMetadata
	The llvm.printf.fmts entry added when a module only uses buffered printf with non-constant format strings.
