           Summary: llvm-g++ -flto generates invalid object files
           Product: tools
           Version: 2.6
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: llvm-g++
        AssignedTo: [email protected]
        ReportedBy: [email protected]
                CC: [email protected]


In current llvm and llvm-gcc 2.6 branches, llvm-g++ -flto generates invalid
object files:

$ cat test.cpp
#include <iostream>
using namespace std;
int main(int argc, char **argv) {
    cerr << "Microsoft sucks!" << endl;
}
$ llvm-g++ -flto test.cpp
/tmp/ccboFcxx.o: file not recognized: File format not recognized
$ llvm-g++ -flto -c test.cpp -o test.o
$ file test.o
test.o: data

Without -flto, it works as expected.
The size of test.o with -flto is almost twice that of test.o without -flto.
