Vedant Kumar 0877dd14e4 [Driver] Force llvm to install its handlers before lldb's
Install llvm's signal handlers up front to prevent lldb's handlers from being
ignored. This is (hopefully) a stopgap workaround.

When lldb invokes an llvm API that installs signal handlers (e.g.
llvm::sys::RemoveFileOnSignal, possibly via a compiler embedded within lldb),
lldb's signal handlers are overriden if llvm is installing its handlers for the
first time.

To work around llvm's behavior, force it to install its handlers up front, and
*then* install lldb's handlers. In practice this is used to prevent lldb test
processes from exiting due to IO_ERR when SIGPIPE is received.

Note that when llvm installs its handlers, it 1) records the old handlers it
replaces and 2) re-installs the old handlers when its new handler is invoked.
That means that a signal not explicitly handled by lldb can fall back to being
handled by llvm's handler the first time it is received, and then by the
default handler the second time it is received.

Sanjay Patel e6c145e054 [DAGCombiner] widen zext of popcount based on target support
zext (ctpop X) --> ctpop (zext X)

This is a prerequisite step for canonicalizing in the other direction (narrow the popcount) in IR - PR43688:
https://bugs.llvm.org/show_bug.cgi?id=43688

I'm not sure if any other targets are affected, but I found a missing fold for PPC, so added tests based on that.
The reason we widen all the way to 64-bit in these tests is because the initial DAG looks something like this:

  t5: i8 = ctpop t4
  t6: i32 = zero_extend t5  <-- created based on IR, but unused node?
    t7: i64 = zero_extend t5

Sterling Augustine 118ceea5c3 Crt files are special cased by name when dealing with ctor and dtor
sections, but the current code misses certain variants. In particular, those
named when clang takes the code path in
clang/lib/Driver/ToolChain.cpp:416, where crtfiles are named:

clang_rt.<component>-<arch>-<env>.<suffix>

Previously, the code only handled:
clang_rt.<component>.<suffix>
<component>.<suffix>

This revision fixes that.

Summary:
[NFC][libomptarget] move remaining device specific code out of omptarget-nvptx.h

Strictly there is one remaining difference wrt amdgcn - parallelLevel is
volatile qualified on amdgcn and not on nvptx. Determining whether this is
correct - and how to represent the different semantics of 'volatile' under
various conditions - is beyond the scope of this code motion patch.

Pavel Labath 96601ec28b ValueObject: Fix a crash related to children address type computation
Summary:
This patch fixes a crash encountered when debugging optimized code. If some
variable has been completely optimized out, but it's value is nonetheless known,
the compiler can replace it with a DWARF expression computing its value. The
evaluating these expressions results in a eValueTypeHostAddress Value object, as
it's contents are computed into an lldb buffer. However, any value that is
obtained by dereferencing pointers in this object should no longer have the
"host" address type.

Lldb had code to account for this, but it was only present in the
ValueObjectVariable class. This wasn't enough when the object being described
was a struct, as then the object holding the actual pointer was a
ValueObjectChild. This caused lldb to dereference the contained pointer in the
context of the host process and crash.

Though I am not an expert on ValueObjects, it seems to me that this children
address type logic should apply to all types of objects (and indeed, applying
applying the same logic to ValueObjectChild fixes the crash). Therefore, I move
this code to the base class, and arrange it to be run everytime the value is
updated.

The test case is a reduced and simplified version of the original debug info
triggering the crash. Originally we were dealing with a local variable, but as
these require a running process to display, I changed it to use a global one
instead.

paulhoad 6df7ef0d8b [clang-format] [NFC] update the documentation in Format.h to allow dump_format_style.py to get a little closer to being correct.
Summary:
Running dump_format_style.py on the tip of the trunk causes ClangFormatStyleOptions.rst to have changes, which I think ideally it shouldn't.

Some recent commits have meant Format.h and ClangFormatStyleOptions.rst have become out of sync such that dump_format_style.py either couldn't be run or generated incorrect .rst files.

It's also important to remember to edit the IncludeStyles from Tooling.

Make a couple of changes {D6833} {D64695} which came from recent clang-format commits that missed this step. There are still a couple of other changes  from commit {D67541} {D68296} which also need to be looked at, but I'd like to park these first two changes first.

The authors of these original commits I've included in the reviewers, I'm happy to work on the changes, just really need to know which is the ground truth of the changes you want to keep (whats in the Format.h) or what is in the ClangFormatStyleOptions.rst

David Tenty 11c2a85db8 [NFC] Rename LLVM_NO_DEAD_STRIP
Summary:
The variable LLVM_NO_DEAD_STRIP is set in LLVM cmake files when building executables that might make use of plugins .The name of the variable does not convey the actual intended usage (i.e. for use with tools that have plugins), just what the eventual effect of setting in on some (i.e. not garbage collecting unused symbols).

This patch renames it to LLVM_SUPPORT_PLUGINS to convey the intended usage, which will allow subsequent patches to add behavior to support that in different ways without confusion about whether it will do on, for example, non-gnu platforms.

SHT_NOTE is the section that consists of

This patch teaches yaml2obj, obj2yaml to dump and parse them.

This patch implements the section how it is described here:
https://docs.oracle.com/cd/E23824_01/html/819-0690/chapter6-18048.html
Which says: "For 64–bit objects and 32–bit objects, each entry is an array of 4-byte words in
the format of the target processor"

The official specification is different
http://www.sco.com/developers/gabi/latest/ch5.pheader.html#note_section
And says: "n 64-bit objects (files with e_ident[EI_CLASS] equal to ELFCLASS64), each entry is an array
of 8-byte words in the format of the target processor. In 32-bit objects (files with e_ident[EI_CLASS]
equal to ELFCLASS32), each entry is an array of 4-byte words in the format of the target processor"

Since LLVM uses the first, 32-bit way, this patch follows it.
