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 &)

    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
`MDLocation`), you need to restrict yourself to those.

Summary:
The 'R' constraint is actually supposed to be much more complicated than
this and is defined in terms of whether it will cause macro expansion in
the assembler. 'R' is getting less useful due to architecture changes and
ought to be replaced by other constraints. We therefore implement 9-bit

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.

[CodeGen] "PromoteInteger" f32 to f64 doesn't make sense.

The original f32->f64 promotion logic was refactored into roughly the
currently shape in r37781. However, starting with r132263, the
legalizer has been split into different kinds, and the previous
"Promote" (which did the right thing) was search-and-replace'd into
"PromoteInteger". The divide gradually deepened, with type legalization
("PromoteInteger") being separated from ops legalization
("Promote", which still works for floating point ops).

Fast-forward to today: there's no in-tree target with legal f64 but
illegal f32 (rather: no tests were harmed in the making of this patch).

With such a target, i.e., if you trick the legalizer into going through
the PromoteInteger path for FP, you get the expected brokenness.
For instance, there's no PromoteIntRes_FADD (the name itself sounds
wrong), so we'll just hit some assert in the PromoteInteger path.

Don't pretend we can promote f32 to f64. Instead, always soften.
