All of the ISA holes are going to make this difficult,
but we can't canonicalize the IR and try to solve PR14613
until we have backend support to get this right.

This patch removes the last reason why DIFlagBlockByrefStruct from

The only point to this change is the test diffs.  When I remove this code entirely (in favor of the recently added generic handling), I don't want there to be any confusion due to spurious test diffs.

As an aside, the fact out tests are AST construction order dependent is not great.  I thought about fixing that, but the reasonable schemes I might want (e.g. sort by name) need the test diffs anyways.

LSR reassociates small constants that fit into add immediate operands as
unfolded offset. Since unfolded offset is not combined with loop-invariant
registers, LSR does not consider solutions that bump invariant registers by
these constants outside the loop.

Some types and callback signatures have changed from TR6 to TR7.
Major changes (only adding signatures and stubs):
(-remove idle callback) done by D48362
-add reduction and dispatch callback
-add get_task_memory and finalize_tool runtime entry points
-ompt_invoker_t  becomes ompt_parallel_flag_t
-more types of sync_regions

It is non-sensical to use cpu-specific/cpu-dispatch multiversioning

There were two combines not covered by the check before now, neither of which
actually differed from normal in the benefit analysis.

The most recent seems to be because it was just added at the top of the
function (naturally). The older is from way back in 2008 (r46687) when we just
didn't put those checks in so routinely, and has been diligently maintained
since.

- Log the reason for a PDB or precompiled-OBJ load failure
- Properly handle out-of-date PDB or precompiled-OBJ signature by displaying a corresponding error
- Slightly change behavior on PDB failure: any subsequent load attempt from another OBJ would result in the same error message being logged
- Slightly change behavior on PDB failure: retry with filename only if previous error was ENOENT ("no such file or directory")
- Tests: a. for native PDB errors; b. cover all the cases above

This will require something to cast. Before this would eliminate

This already worked if only one register piece was used,
but didn't if a type was split into multiple, unequal
sized pieces.

Fixes not splitting 3i16/v3f16 into two registers for
AMDGPU.

This will also allow fixing the ABI for 16-bit vectors
in a future commit so that it's the same for all subtargets.

Summary:
This wasn't actually async (due to std::future destructor blocking).
If it were, we would have clean shutdown issues if main returned
and destroyed Placeholder before the thread is done with it.

We could attempt to avoid any blocking by using shared_ptr or weak_ptr tricks so
the thread can detect Placeholder's destruction, but there are other potential
issues (e.g. loadIndex does tracing, and we'll destroy the tracer...)
Instead, once LSPServer::run returns, we wait for the index to finish loading
before exiting. Performance is not critical in this situation.

[Analyzer] Iterator Checker - Part 8: Support for assign, clear, insert, emplace and erase operations

This patch adds support for the following operations in the iterator checkers: assign, clear, insert, insert_after, emplace, emplace_after, erase and erase_after. This affects mismatched iterator checks ("this" and parameter must match) and invalidation checks (according to the standard).

Differential Revision: https://reviews.llvm.org/D32904

This patch adds support for the following operations in the iterator checkers: push_back, push_front, emplace_back, emplace_front, pop_back and pop_front. This affects iterator range checks (range is extended after push and emplace and reduced after pop operations) and invalidation checks (according to the standard).

Differential Revision: https://reviews.llvm.org/D32902

llvm-svn: 341793

Extension of the mismatched iterator checker for constructors taking range of first..last (first and last must be iterators of the same container) and also for comparisons of iterators of different containers (one does not compare iterators of different containers, since the set of iterators is partially ordered, there are no relations between iterators of different containers, except that they are always non-equal).

Differential Revision: https://reviews.llvm.org/D32860

llvm-svn: 341792

If a container is moved by its move assignment operator, according to the standard all their iterators except the past-end iterators remain valid but refer to the new container. This patch introduces support for this case in the iterator checkers.
