SplitVecOp_TRUNCATE has logic for recursively splitting oversize vectors

DebugInfo: Remove dead code from old DebugLoc API

Remove old API for `DebugLoc` now that all the callers have been
updated.  If this broke your out-of-tree build, here's a quick map from
the old API to the new one:

    DebugLoc DebugLoc::getFromMDLocation(MDNode *)
      => DebugLoc::DebugLoc(MDLocation *)
      => explicit DebugLoc::DebugLoc(MDNode *) // works with broken code

    MDNode *DebugLoc::getAsMDNode(LLVMContext &)
      => MDLocation *DebugLoc::get()
      => DebugLoc::operator MDLocation *()
      => MDNode *DebugLoc::getAsMDNode() // works with broken code

    bool DebugLoc::isUnknown()
      => DebugLoc::operator MDLocation *()
          i.e.: if (MDLocation *DL = ...)
      => DebugLoc::operator bool() // works with broken code
          i.e.: if (DebugLoc DL = ...)

    void DebugLoc::getScopeAndInlinedAt(MDNode *&, MDNode *&)
      => use: MDNode *DebugLoc::getScope()
         and: MDLocation *DebugLoc::getInlinedAt()

    MDNode *DebugLoc::getScopeNode(LLVMContext &)
      => MDNode *DebugLoc::getInlinedAtScope()

    void DebugLoc::dump(LLVMContext &)
      => void DebugLoc::dump()

    void DebugLoc::getFnDebugLoc(LLVMContext &)
      => void DebugLoc::getFnDebugLoc()

    MDNode *DebugLoc::getScope(LLVMContext &)
      => MDNode *DebugLoc::getScope()

    MDNode *DebugLoc::getInlinedAt(LLVMContext &)
      => MDLocation *DebugLoc::getInlinedAt()

I've noted above the only functions that won't crash on broken code (due
to downcasting to `MDLocation`).  If your code could be dealing with
broken IR (i.e., you haven't run the verifier yet, or you've used a
temporary node that will eventually (but not yet) get RAUW'ed to an

9 years ago[MCJIT][Orc] Refactor RTDyldMemoryManager, weave RuntimeDyld::SymbolInfo through
Lang Hames [Mon, 30 Mar 2015 03:37:06 +0000 (03:37 +0000)]
[MCJIT][Orc] Refactor RTDyldMemoryManager, weave RuntimeDyld::SymbolInfo through
MCJIT.

This patch decouples the two responsibilities of the RTDyldMemoryManager class,
memory management and symbol resolution, into two new classes:
RuntimeDyld::MemoryManager and RuntimeDyld::SymbolResolver.

The symbol resolution interface is modified slightly, from:

  uint64_t getSymbolAddress(const std::string &Name);

to:

  RuntimeDyld::SymbolInfo findSymbol(const std::string &Name);

The latter passes symbol flags along with symbol addresses, allowing RuntimeDyld
and others to reason about non-strong/non-exported symbols.

The memory management interface removes the following method:

  void notifyObjectLoaded(ExecutionEngine *EE,
                          const object::ObjectFile &) {}

as it is not related to memory management. (Note: Backwards compatibility *is*
maintained for this method in MCJIT and OrcMCJITReplacement, see below).

The RTDyldMemoryManager class remains in-tree for backwards compatibility.
It inherits directly from RuntimeDyld::SymbolResolver, and indirectly from
RuntimeDyld::MemoryManager via the new MCJITMemoryManager class, which
just subclasses RuntimeDyld::MemoryManager and reintroduces the
notifyObjectLoaded method for backwards compatibility).

The EngineBuilder class retains the existing method:

  EngineBuilder&
  setMCJITMemoryManager(std::unique_ptr<RTDyldMemoryManager> mcjmm);

and includes two new methods:

  EngineBuilder&
  setMemoryManager(std::unique_ptr<MCJITMemoryManager> MM);

  EngineBuilder&
  setSymbolResolver(std::unique_ptr<RuntimeDyld::SymbolResolver> SR);

Clients should use EITHER:

A single call to setMCJITMemoryManager with an RTDyldMemoryManager.

OR (exclusive)

One call each to each of setMemoryManager and setSymbolResolver.

This patch should be fully compatible with existing uses of RTDyldMemoryManager.
If it is not it should be considered a bug, and the patch either fixed or
reverted.

If clients find the new API to be an improvement the goal will be to deprecate
and eventually remove the RTDyldMemoryManager class in favor of the new classes.
