Lang Hames 7acaefabf6 [MCJIT] Clean up RuntimeDyld's quirky object-ownership/modification scheme. ... Previously, when loading an object file, RuntimeDyld (1) took ownership of the ObjectFile instance (and associated MemoryBuffer), (2) potentially modified the object in-place, and (3) returned an ObjectImage that managed ownership of the now-modified object and provided some convenience methods. This scheme accreted over several years as features were tacked on to RuntimeDyld, and was both unintuitive and unsafe (See e.g. http://llvm.org/PR20722). This patch fixes the issue by removing all ownership and in-place modification of object files from RuntimeDyld. Existing behavior, including debugger registration, is preserved. Noteworthy changes include: (1) ObjectFile instances are now passed to RuntimeDyld by const-ref. (2) The ObjectImage and ObjectBuffer classes have been removed entirely, they existed to model ownership within RuntimeDyld, and so are no longer needed. (3) RuntimeDyld::loadObject now returns an instance of a new class, RuntimeDyld::LoadedObjectInfo, which can be used to construct a modified object suitable for registration with the debugger, following the existing debugger registration scheme. (4) The JITRegistrar class has been removed, and the GDBRegistrar class has been re-written as a JITEventListener. This should fix http://llvm.org/PR20722 . git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222810 91177308-0d34-0410-b5e6-96231b3b80d8		2014-11-26 06:53:26 +00:00
