Joe Ellis 67464dfe36 [DebugInfo] Only perform TypeSize -> unsigned cast when necessary
This commit moves a line in SelectionDAGBuilder::handleDebugValue to
avoid implicitly casting a TypeSize object to an unsigned earlier than
necessary. It was possible that we bail out of the loop before the value
is ever used, which means we could create a superfluous TypeSize
warning.

Alex Zinenko 0881a4f1bf [mlir] make ModuleTranslation mapping fields private
ModuleTranslation contains multiple fields that keep track of the mappings
between various MLIR and LLVM IR components. The original ModuleTranslation
extension model was based on inheritance, with these fields being protected and
thus accessible in the ModuleTranslation and derived classes. The
inheritance-based model doesn't scale to translation of more than one derived
dialect and will be progressively replaced with a more flexible one based on
dialect interfaces and a translation state that is separate from
ModuleTranslation. This change prepares the replacement by making the mappings
private and providing public methods to access them.

Valeriy Savchenko 81a9707723 [Attr] Apply GNU-style attributes to expression statements
Before this commit, expression statements could not be annotated
with statement attributes.  Whenever parser found attribute, it
unconditionally assumed that it was followed by a declaration.
This not only doesn't allow expression attributes to have attributes,
but also produces spurious error diagnostics.

In order to maintain all previously compiled code, we still assume
that GNU attributes are followed by declarations unless ALL of those
are statement attributes.  And even in this case we are not forcing
the parser to think that it should parse a statement, but rather
let it proceed as if no attributes were found.

Pavel Labath 7df4eaaa93 [lldb/test] Automatically find debug servers to test
Our test configuration logic assumes that the tests can be run either
with debugserver or with lldb-server. This is not entirely correct,
since lldb server has two "personalities" (platform server and debug
server) and debugserver is only a replacement for the latter.

A consequence of this is that it's not possible to test the platform
behavior of lldb-server on macos, as it is not possible to get a hold of
the lldb-server binary.

One solution to that would be to duplicate the server configuration
logic to be able to specify both executables. However, that seems
excessively redundant.

A well-behaved lldb should be able to find the debug server on its own,
and testing lldb with a different (lldb-|debug)server does not seem very
useful (even in the out-of-tree debugserver setup, we copy the server
into the build tree to make it appear "real").

Therefore, this patch deletes the configuration altogether and changes
the low-level server retrieval functions to be able to both lldb-server
and debugserver paths. They do this by consulting the "support
executable" directory of the lldb under test.

Max Kazantsev 3d15b7e7df [Codegenprepare][X86] Use usub with overflow opt for IV increment
Function `replaceMathCmpWithIntrinsic` artificially limits the scope
of the optimization, setting a requirement of two instructions be in
the same block, due to two reasons:
- usage of DT for more general check is costly in terms of compile time;
- risk of creating a new value that lives through multiple blocks.

Because of this, two semantically equivalent tests may be or not be the
subject of this opt depending on where the binary operation is located.
See `test/CodeGen/X86/usub_inc_iv.ll` for motivation

There is one important particular case where this limitation is  too strict:
it is when the binary operation is the increment of the induction variable.
As result, the application of this opt becomes fragile and highly reliant on
where other passes decide to place IV increment. In most cases, they place
it in the end of the latch block, killing the opt opportunity (when in fact it
does not matter where to insert the actual instruction).

This patch handles this particular case separately.
- The detector does not use dom tree and has constant cost;
- The value of IV or IV.next lives through all loop in any case, so this should not
  create a new unexpected long-living value.

As result, the transform becomes more robust. It also seems to lead to
better code generation in some cases (see `test/CodeGen/X86/lsr-loop-exit-cond.ll`).

but the header itself may by be included together with other headers

declare a class 'MemoryAccess' which may conflict.

Instead of prefixing everything in Polly's header files, this patch adds

commonly used symbols into the mlir namespace.
