* Remove various print methods that called the Value* method, just have one that all subclasses of Value will use anyway. * Remove template for printing constant references * Add methods to print char* and strings * setStream now sets the stream on the contained AssemblyWriter git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13246 91177308-0d34-0410-b5e6-96231b3b80d8

|
|
// chunks of LLVM. This is used when a module is not being changed, but random
|
|
// parts of it need to be printed. This can greatly speed up printing of LLVM

|
// output.
