2016-05-11[NFC] Remove some dead code:Filipe Cabecinhas1-3/+0
DbgInfoIntrinsic::StripCast() is dead since r79977 The only function that creates Comdat objects seems to be in Module, and always creates them using the default constructor. llvm-svn: 269204
2014-06-27IR: Add COMDATs to the IRDavid Majnemer1-0/+25
This new IR facility allows us to represent the object-file semantic of a COMDAT group. COMDATs allow us to tie together sections and make the inclusion of one dependent on another. This is required to implement features like MS ABI VFTables and optimizing away certain kinds of initialization in C++. This functionality is only representable in COFF and ELF, Mach-O has no similar mechanism. Differential Revision: http://reviews.llvm.org/D4178 llvm-svn: 211920
