| virtual const X86Subtarget* llvm::X86TargetMachine::getSubtargetImpl | ( | ) | const [inline, virtual] |
getSubtargetImpl - virtual method implemented by subclasses that returns a reference to that target's TargetSubtarget-derived member variable.

getRegisterInfo - If register information is available, return it. If not, return null. This is kept separate from RegInfo until RegInfo has details of graph coloring register allocation removed from it.

Definition at line 64 of file X86TargetMachine.h.
References llvm::X86Subtarget::isTargetELF().
getModuleMatchQuality - This static method should be implemented by targets to indicate how closely they match the specified module. This is used by the LLC tool to determine which target to use when an explicit -march option is not specified. If a target returns zero, it will never be chosen without an explicit -march option.
Reimplemented from llvm::TargetMachine.
Reimplemented in llvm::X86_32TargetMachine, and llvm::X86_64TargetMachine.
| static unsigned llvm::X86TargetMachine::getJITMatchQuality | ( | ) | [static] |
getJITMatchQuality - This static method should be implemented by targets that provide JIT capabilities to indicate how suitable they are for execution on the current host. If a value of 0 is returned, the target will not be used unless an explicit -march option is used.
Reimplemented from llvm::TargetMachine.

Target-Independent Code Generator Pass Configuration Options.
addInstSelector - This method should add any "last minute" LLVM->LLVM passes, then install an instruction selector pass, which converts from LLVM code to machine instructions.

| bool | ||||

addPreRegAllocPasses - This method may be implemented by targets that want to run passes immediately before register allocation. This should return true if -print-machineinstrs should print after these passes.

addPostRegAllocPasses - This method may be implemented by targets that want to run passes after register allocation but before prolog-epilog insertion. This should return true if -print-machineinstrs should print after these passes.

addAssemblyEmitter - This pass should be overridden by the target to add the asmprinter, if asm emission is supported. If this is not supported, 'true' should be returned.

addCodeEmitter - This pass should be overridden by the target to add a code emitter, if supported. If this is not supported, 'true' should be returned. If DumpAsm is true, the generated assembly is printed to cerr.
