Summary:
This option appears to have been dropped as part of the refactoring in
r331663. Unfortunately, if we want to use llvm-strip as a drop-in
replacement for strip, this option should still be available.

Corrupted minidumps was leading to unpredictable behavior.
This change adds explicit consistency checks for the minidump early on. The
checks are not comprehensive but they should catch obvious structural violations:
streams with type == 0
duplicate streams (same type)
overlapping streams
truncated minidumps
Another early check is to make sure we actually support the minidump architecture
instead of crashing at a random place deep inside LLDB.

Summary:
This patch eliminates some redundancy in iterating across Listeners for the
Instruction and Stall HWEvents, by introducing a template onEvent routine.
This change was suggested by @courbet in https://reviews.llvm.org/D48576. I
hope that this patch addresses that suggestion appropriately. I do like this
change better than what we had previously.

several nested parallel dynamic loops.

While that fold is clearly not happening [anymore],
we do now have separate test cases for these cases,
so we should be ok to slightly adjust these tests
to not potentially loose test coverage.

We have located a bug in AssemblyWriter::printModuleSummaryIndex(). This
function outputs path strings incorrectly. Backslashes in the strings
are not correctly escaped.
Consequently, if a path name contains a backslash followed by two
hexadecimal characters, the sequence is incorrectly interpreted when the
output is read by another component. This mangles the path and results
in error.
This patch fixes this issue by calling printEscapedString() to output
the module paths.

The variable name `SANITIZER_HEADERS` is already used for the list of

As the code for the checker grew, it became increasinly difficult to see
whether a function was global or statically defined. In this patch,
anything that isn't a type declaration or definition was moved out of the
anonymous namespace and is marked as static.
llvm-svn: 336901
Noticed while updating D42044, lowerV2X128VectorShuffle can improve the shuffle mask with the zeroable data to create a target shuffle mask to recognise more 'zero upper 128' patterns.
NOTE: lowerV4X128VectorShuffle could benefit as well but the code needs refactoring first to discriminate between SM_SentinelUndef and SM_SentinelZero for negative shuffle indices.

Summary:
Importing a function having a struct definition in the parameter list
causes a crash in the importer via infinite recursion. This patch avoids
the crash and reports such functions as not supported. Unit tests make
sure that normal struct definitions inside function bodies work normally
on the other hand and LLDB-like type imports also do.

Differential revision: https://reviews.llvm.org/D49060
llvm-svn: 336897
Summary:
Generalize the creation of Decl nodes during Import. With this patch we do the
same things after and before a new AST node is created (::Create) The import
logic should be really simple, we create the node, then we mark that as
imported, then we recursively import the parts for that node and then set them
on that node. However, the AST is actually a graph, so we have to handle
circles. If we mark something as imported (`MapImported()`) then we return with
the corresponding `To` decl whenever we want to import that node again, this way
circles are handled. In order to make this algorithm work we must ensure
things, which are handled in the generic CreateDecl<> template:
* There are no `Import()` calls in between any node creation (::Create)
and the `MapImported()` call.
* Before actually creating an AST node (::Create), we must check if
the Node had been imported already, if yes then return with that one.
One very important case for this is connected to templates: we may
start an import both from the templated decl of a template and from
the template itself.
Now, the virtual `Imported` function is called in `ASTImporter::Impor(Decl *)`,
but only once, when the `Decl` is imported. One point of this refactor is to
separate responsibilities. The original `Imported()` had 3 responsibilities:
- notify subclasses when an import happened
- register the decl into `ImportedDecls`
- initialise the Decl (set attributes, etc)
Now all of these are in separate functions:
- `Imported`
- `MapImported`
- `InitializeImportedDecl`
I tried to check all the clients, I executed tests for `ExternalASTMerger.cpp`
and some unittests for lldb.

Summary:
Someone must be responsible for handling an Error. When formatv takes
ownership of an Error, the formatv_object destructor must take care of this.
Passing an error by value to formatv() is not considered explicit enough to mark
the error as handled (see D49013), so we require callers to use a format adapter
to confirm this intent.

```
if (DTU.getUpdateStrategy() == DomTreeUpdater::UpdateStrategy::Lazy) {

if (DTU.getUpdateStrategy() == DomTreeUpdater::UpdateStrategy::Eager) {
...
}
```
After the patch, they can avoid code patterns above
```

The boolean tracking whether we saw a kill of the flags was supposed to
be per-block we are scanning and instead was outside that loop and never
cleared. It requires a quite contrived test case to hit this as you have
to have multiple levels of successors and interleave them with kills.
I've included such a test case here.
