hmm. that can not be true. It was applied by Evan on May 07, 2007 to  
unbreak Apple style builds.

this difference exists between llvm-gcc-4.0 (the mirror) and llvm-gcc-4.2
today, check llvm-linker-hack.cpp yourself if you like.  There was a change
to the mirror in May 07, but it was just changing Bytecode -> Bitcode.  My
guess is the Evan's change didn't reach the mirror.  Here is the
function
as it exists in the llvm-gcc-4.0 mirror today:

void dummy_function() {
  new llvm::ExistingModuleProvider(0);
  llvm::createVerifierPass();
  llvm::WriteBitcodeToFile(0, llvm::cout);
  llvm::ParseBitcodeFile(NULL);
...

and in llvm-gcc-4.2:
void dummy_function() {
  new llvm::ExistingModuleProvider(0);
  llvm::createVerifierPass();
  llvm::CreateBitcodeWriterPass(*llvm::cout);
  llvm::WriteBitcodeToFile(0, *llvm::cout);
  llvm::ParseBitcodeFile(NULL);
  llvm::MemoryBuffer::getNewMemBuffer(0);

If the llvm-gcc-4.2 version is correct, the mirror needs to be corrected.
Not sure how to do that...

Ciao,

Duncan.

I checked out llvm-gcc-4.0 from mirror svn server and our internal svn.
And I do see the difference, but I do not understand why.

Bill, any idea ?
