Author: hans

New Revision: 156479

URL: http://llvm.org/viewvc/llvm-project?rev=156479&view=rev
Log:
Introduce llvm-c function LLVMPrintModuleToFile.

This lets you save the textual representation of the LLVM IR to a file.
Before this patch it could only be printed to STDERR from llvm-c.

Patch by Carlo Kok!
