Option checks for cases where a version script explicitly lists
a symbol, but the symbol is not defined and errors out such
cases if any.

Summary:
Currently output of child process, however in my use case, it
needs to be captured and presented to the user.
Add Redirect method to Compilation and use existing infrastructure
for redirecting output of commands.

This patch enhances dot graph viewer to show hot regions
with hot bbs/edges displayed in red. The ratio of the bb
freq to the max freq of the function needs to be no less
than the value specified by view-hot-freq-percent option.
The default value is 10 (i.e. 10%).

MBFI supports profile count dumping and function
name based filtering. Add these two feature to
BFI as well. The filtering option is shared between
BFI and MBFI: -view-bfi-func-name=..

If the load is conditional we can't hoist its 0-iteration instance to
the preheader because that would make it unconditional. Thus we would
access a memory location that the original loop did not access.

BFI and MBFI's dot traits class share most of the
code and all future enhancement. This patch extracts
common implementation into base class BFIDOTGraphTraitsBase.
This patch also enables BFI graph to show branch probability
on edges as MBFI does before.

Recently, Microsoft added support for a flag, /std, which controls which
version of the language rules MSVC should use.
MSVC hasn't updated __cplusplus though.
Instead, they added a new macro, _MSVC_LANG, which is defined in a
similar fashion to __cplusplus. This is used to indicate which mode the
compiler is in.

Passing -output-dir path/to/dir to llvm-cov show creates path/to/dir if
it doesn't already exist, and prints reports into that directory.
In function view mode, all views are written into
path/to/dir/functions.$EXTENSION. In file view mode, all views are
written into path/to/dir/coverage/$PATH.$EXTENSION.
Changes since the initial commit:
- Avoid accidentally closing stdout twice.

It is only used internally by the ScopInfo pass. By moving it into its
own header file we avoid it being processed that use only ScopInfo.

The methods in ScopBuilder are used for the construction of a Scop,
while the remaining classes of ScopInfo are required by all passes that
use Polly's polyhedral analysis.
llvm-svn: 273982
This function is used by both ScopInfo and ScopBuilder. A common
location for this function is required when ScopInfo and ScopBuilder are
separated into separate files in the next commit.

This reverts commit r273971. test/profile/instrprof-visibility.cpp is
failing because of an uncaught error in SafelyCloseFileDescriptor.

DiagnosticNoteRenderer asserts trying to emit its "while building
module Foo imported from bar.h:5" note when the presumed location
of the import is invalid. This assertion was added in r267914,
where most uses of 'getFilename' were updated to test 'isValid'
instead. This one must have been missed.
I can't come up with a test because this location is always valid
in C-based code, but external clients that manually import modules
(*cough*Swift*cough*) sometimes provide invalid SourceLocations.

A few fixes:
- Check the process state to make sure it is stopped
- Grab the frame from the "exe_ctx" so this will work during breakpoint callbacks
- Print out the SBDeclaration objects of the variables that shadow each other so we can see the source locations of which variable declarations are shodowing each other.

the new pass manager.
This adds operator<< overloads for the various bits of the
LazyCallGraph, dump methods for use from the debugger, and debug logging
using them to the CGSCC pass manager.
Having this was essential for debugging the call graph update patch, and
I've extracted what I could from that patch here to minimize the delta.

Target::Install() was assuming the module at index 0 was the executable.
This is often true, but not guaranteed to be the case. The
TestInferiorChanged.py test highlighted this when run against iOS.
After the binary is replaced in the middle of the test, it becomes the
last module in the list. The rest of the Target::Install() logic then
clobbers the executable file by using whatever happens to be the first
module in the target module list.
This change also marks the TestInferiorChanged.py test as a no-debug-info
test.

Apparently, MSVC complains if there's an implicit conversion from
`unsigned` to `unsigned long long`, if the `unsigned` is the result of
a bit shift.

explicit in how it adds the kernel binary, to guard against the
case where a kernel corefile might incorrectly include the kernel's
UUID in it (so calling ::GetSharedModule may end up returning the
global module cache's copy of the core file instead of adding the
kerenl binary).
