示例1: JIT
/// create - Create an return a new JIT compiler if there is one available
/// for the current target. Otherwise, return null.
///
ExecutionEngine *JIT::create(ModuleProvider *MP, IntrinsicLowering *IL) {
if (MArch == 0) {
std::string Error;
MArch = TargetMachineRegistry::getClosestTargetForJIT(Error);
if (MArch == 0) return 0;
} else if (MArch->JITMatchQualityFn() == 0) {
std::cerr << "WARNING: This target JIT is not designed for the host you are"
<< " running. If bad things happen, please choose a different "
<< "-march switch.\n";
}
// Allocate a target...
TargetMachine *Target = MArch->CtorFn(*MP->getModule(), IL);
assert(Target && "Could not allocate target machine!");
// If the target supports JIT code generation, return a new JIT now.
if (TargetJITInfo *TJ = Target->getJITInfo())
return new JIT(MP, *Target, *TJ);
return 0;
