Functions

FunctionPassllvm::createX86ISelDag (X86TargetMachine &TM, CodeGenOpt::Level OptLevel)
 This pass converts a legalized DAG into a X86-specific DAG, ready for instruction scheduling. More...
 
FunctionPassllvm::createX86GlobalBaseRegPass ()
 This pass initializes a global base register for PIC on x86-32. More...
 
FunctionPassllvm::createCleanupLocalDynamicTLSPass ()
 This pass combines multiple accesses to local-dynamic TLS variables so that the TLS base address for the module is only fetched once per execution path through the function. More...
 
FunctionPassllvm::createX86FloatingPointStackifierPass ()
 This function returns a pass which converts floating-point register references and pseudo instructions into floating-point stack references and physical instructions. More...
 
FunctionPassllvm::createX86IssueVZeroUpperPass ()
 This pass inserts AVX vzeroupper instructions before each call to avoid transition penalty between functions encoded with AVX and SSE. More...
 
FunctionPassllvm::createX86PadShortFunctions ()
 Return a pass that pads short functions with NOOPs. More...
 
FunctionPassllvm::createX86FixupLEAs ()
 Return a pass that selectively replaces certain instructions (like add, sub, inc, dec, some shifts, and some multiplies) by equivalent LEA instructions, in order to eliminate execution delays in some processors. More...
 
FunctionPassllvm::createX86OptimizeLEAs ()
 Return a pass that removes redundant LEA instructions and redundant address recalculations. More...
 
FunctionPassllvm::createX86FixupSetCC ()
 Return a pass that transforms setcc + movzx pairs into xor + setcc. More...
 
FunctionPassllvm::createX86WinAllocaExpander ()
 Return a pass that expands WinAlloca pseudo-instructions. More...
 
FunctionPassllvm::createX86CallFrameOptimization ()
 Return a pass that optimizes the code-size of x86 call sequences. More...
 
FunctionPassllvm::createX86WinEHStatePass ()
 Return an IR pass that inserts EH registration stack objects and explicit EH state updates. More...
 
FunctionPassllvm::createX86ExpandPseudoPass ()
 Return a Machine IR pass that expands X86-specific pseudo instructions into a sequence of actual instructions. More...
 
FunctionPassllvm::createX86CmovConverterPass ()
 This pass converts X86 cmov instructions into branch when profitable. More...
 
FunctionPassllvm::createX86FixupBWInsts ()
 Return a Machine IR pass that selectively replaces certain byte and word instructions by equivalent 32 bit instructions, in order to eliminate partial register usage, false dependences on the upper portions of registers, and to save code size. More...
 
FunctionPass * llvm::createX86DomainReassignmentPass ()
 Return a Machine IR pass that reassigns instruction chains from one domain to another, when profitable. More...
 
void llvm::initializeFixupBWInstPassPass (PassRegistry &)
 
FunctionPassllvm::createX86EvexToVexInsts ()
 This pass replaces EVEX encoded of AVX-512 instructiosn by VEX encoding when possible in order to reduce code size. More...
 
InstructionSelectorllvm::createX86InstructionSelector (const X86TargetMachine &TM, X86Subtarget &, X86RegisterBankInfo &)
 
void llvm::initializeEvexToVexInstPassPass (PassRegistry &)
