The files were never written to and then deleted, but they were created
nonetheless. To prevent that, create a wrapper around the 2 variants of
createUniqueFile and use the one that only does an access(Exists) call
to check for name unicity in -no-output mode.

We are using Writer more like a function instead of a class.
This patch makes it a function to simplify the interface.
All details of Writer class is now hidden from other parts of the linker.

Rename `remap()` to `remapOperands()`, and restrict its contract to
remapping operands. Previously, it also called `mapToMetadata()`, but
this logic is hard to reason about externally. In particular, this
refactors `mapUniquedNode()` to avoid redundant mapping calls, taking
advantage of the RAUWs that are already in place.

Summary: The casts from String to PatFrag weren't needed if we instead provided an SDNode. This fix was suggested by @pete in D11382.

More specifically, make NVPTXISelDAGToDAG able to emit cached loads (LDG) for pointer induction variables.
Also fix latent bug where LDG was not restricted to kernel functions. I believe that this could not be triggered so far since we do not currently infer that a pointer is global outside a kernel function, and only loads of global pointers are considered for cached loads.

This is intended to help support the idiom of a class that has some
other objects (or multiple arrays of different types of objects)
appended on the end, which is used quite heavily in clang.

useless return value. Switch to using it directly when completing the
redeclaration chain for an anonymous declaration, and reduce the set of

This option allows to select a subset of the architectures when
performing a universal binary link. The filter is done completely

1. Create a utility function normalizeEdgeWeights() in MachineBranchProbabilityInfo that normalizes a list of edge weights so that the sum of then can fit in uint32_t.
2. Provide an interface in MachineBasicBlock to normalize its successors' weights.
3. Add a flag in MachineBasicBlock that tracks whether its successors' weights are normalized.
4. Provide an overload of getSumForBlock that accepts a non-const pointer to a MBB so that it can force normalizing this MBB's successors' weights.
5. Update several uses of getSumForBlock() by eliminating the once needed weight scale.

This patch adds flags -fno-profile-instr-generate and
-fno-profile-instr-use, and the GCC aliases -fno-profile-generate and
-fno-profile-use.
These flags are used in situations where users need to disable profile
generation or use for specific files in a build, without affecting other
files.

Summary: PR24191 finds that the expected memory-register operations aren't generated when relaxed { load ; modify ; store } is used. This is similar to PR17281 which was addressed in D4796, but only for memory-immediate operations (and for memory orderings up to acquire and release). This patch also handles some floating-point operations.

pass manager.
This never worked, and won't ever work. It was actually why I ended up
building the LazyCallGraph set of code which is more more effectively
wired up to the new pass manager. This accidentally got committed when
I was trying to land a cleanup of the code organization in the other
parts of this file. =[ My bad, but fortunately Dave was keen eyed enough
to spot that this code couldn't possibly work. =]

Since the docs were written, we've added the BPF backend to the list.
Updating the docs to take this in to account. Also sorted them to
match cmake while I was changing these lines.

The only place that tries to return a CallGraph by value
(CallGraphAnalysis::run) doesn't seem to be used right now, but it's a
reasonable bit of cleanup anyway.

LoadedObjectInfo was depending on the implicit copy ctor in the presence
of a user-declared dtor. Default (and protect) it in the base class and
make the devired classes final to avoid any risk of a public API that
would enable slicing.
