Summary:
This change makes the tests more focused and avoids problematic
interactions between the testing modes and instruction encoding. This
change also allows the other tests to use less verbose output and
stricter checks.

Eventually we need to be able to support nested types, which don't
have an associated CVType record.  To handle this, remove the
CVType from all of the record classes, and instead store the
deserialized record.  Then move the deserialization up to the thing
that creates the type.  This actually makes error handling better
anyway as we can return an invalid symbol instead of asserting false.

The patch saves a function offset table which maps function name index to the
offset of its function profile to the start of the binary profile. By using
the function offset table, for those function profiles which will not be used
when compiling a module, the profile reader does't have to read them. For
profile size around 10~20M, it saves ~10% compile time.

This test constructs a non-readable file of mode 0111, which lingers in the test output directory and will cause EACCES to various tools (rg, rsync, ...)

The test diffs are all cosmetic due to the change in
value naming, but I'm including that to show that the
new code does perform these folds rather than something
else in instcombine.

The test used to fail with an invalid phi node: the two predecessors were outlined
and the SSA representation was left invalid. The patch adds the exit block to the
cold region.

llvm-svn: 342277

remove duplicate entries from isSingleEntrySingleExit: the Entry block is
already added by the loop over the dominance frontier.

Remove the heuristic from isOutlineCandidate that a region is too small when it
only contains a basic block. With this change we now grow regions starting from
a block and we continue adding to the ValidColdRegion. Check the heuristic just
before code generation.

Also fix a problem in forward propagation:
  const TerminatorInst *TI = It->getTerminator();
was set outside the while loop that iterates over It.

Summary:
The multiprocess module uses pickling to transfer
information between processes and does not know how to pickle
the class created in the lit.cfg file and thus the example
fails.

Implement ManyTests in a separate file and import for the

This patch fixes the debug info handling for SelectionDAG legalization
of DAG nodes with two results. When an replaced SDNode has more than
one result, transferDbgValues was always copying the SDDbgValue from
the first result and attaching them to all members. In reality
SelectionDAG::ReplaceAllUsesWith() is given an array of SDNodes
(though the type signature doesn't make this obvious (cf. the call
site code in ReplaceNode()).

Summary:
During threaded thinLTO, it is possible that the entry for current
module doesn't exist in StringMaps (like ExportLists, ResolvedODR,
etc.). Using operator[] might trigger a rehash for the StringMap, which
might happen on multiple threads at the same time.

Attempt to lower a shuffle as an unpack of elements from two inputs followed by a single-input (wider) permutation.

As long as the permutation is wider this is a win - there may be some circumstances where same size permutations would also be useful but I've left that for future work.

Introduce explicit add_unittest_with_input_files target for tests that use llvm::getInputFileDirectory()

Using llvm::getInputFileDirectory() in unit tests is discouraged, so require an explicit opt-in.
This way, cmake also writes ~60 fewer unused files to disk.

Also added a C-interface function for large values, and updated
llvm-lto's --thinlto-cache-max-size-bytes switch to take a type larger
than int.

The maximum cache size in terms of bytes is a 64-bit number. However,
the methods to set it only took unsigned previously, which meant that
the maximum cache size could not be specified above 4GB. That's quite
small compared to the output of some projects, so it makes sense to
provide the ability to set larger values in that field.

We also needed a C-interface function that provides a greater range
than the existing thinlto_codegen_set_cache_size_bytes, which also only
takes an unsigned, so this change also adds
hinlto_codegen_set_cache_size_megabytes.

Summary:
GFX9 and above support sin/cos instructions with a greater range and thus don't
require a fract instruction prior to invocation.

Added a subtarget feature to reflect this and added code to take advantage of
expanded range on GFX9+

Also updated the tests to check correct behaviour
