In my main function after generate the code and before start the execution via
JIT I do this:
ExecutionEngine *EE = EngineBuilder(M).create();
string str =
EE->getTargetData()->getStringRepresentation();
str[0] = 'e';
M->setDataLayout(str);
if (verifyModule(*M)) {
errs() << argv[0] << ": Error building the
function!\n";
return 1;
}
vector<GenericValue> noargs;
GenericValue GV = EE->runFunction(Main, noargs);
outs() << "Result: " << GV.IntVal <<
"\n";
return 0;
Why are you changing the data layout to be little-endian?
