the MCJIT execution engine. The GDB JIT debugging integration support works by registering a loaded object image with a pre-defined function that GDB will monitor if GDB is attached. GDB integration support is implemented for ELF only at this time. This integration requires GDB version 7.0 or newer. Patch by Andy Kaylor! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154868 91177308-0d34-0410-b5e6-96231b3b80d8
