This patch is in preparation for writing the header replacement to disk.
Added getUniqueHeaderName() that generates a unique header filename in
the same directory as the header file.

Some changes to r185811 broke certain build configurations. These changes should
fix them.

* Some file headers were missing for files in Core/
* Some headers were included but not necessary
* CMakeLists.txt was linking in LLVMSupport even though CMakeLists in subdirs
were linking it in too.
* StringRefisation of constructors of types in FileOverrides.h
* Other misc cleanups

* all transforms are in the same category
* all transforms' options are in the same category
* display the CommonOptionParser extra-help (which describe in more details the
compilation database stuff)
* add EXAMPLES section

Add a new transform to replace uses of 'std::auto_ptr' by 'std::unique_ptr'.
Copy-ctor and assign-operator are wrapped with a call to 'std::move()'.
Note that until header modification is ready it is not that useful, that's why
it's marked as (EXPERIMENTAL) in the command line description and a "Known
Limitations" section is present in the transform documentation.

sys::fs::make_absolute was turning '.' into '<path>/.' which broke prefix
comparison logic. Stripping these extra chars fixes the problem.
llvm-svn: 184322
Transforms will now make changes to headers if header modifications have been
enabled.
FIXME: Only UseNullptr contains a cursory header modification test. Other
transforms should have them too.
llvm-svn: 184197
To make it possible for replacements made to headers as part of transforming
one translation unit to not be visible to the transform of other translation
units, Transform now handles replacement application as part of its
end-of-source handling. Several things were simplified as a result:
- The duplicated code in every transform for applying replacements is now gone
and replaced with one location in Transform.
- RefactoringTool is no longer used since Transform houses the Replacements
structure.
- RewriterContainer is now a private implementation detail of Transform (also
renamed to RewriterManager since its behaviour is slightly different now with
respect to lifetime of objects).
- There's now no distinction between input and output file state.
Misc notes:
- Interface changes reflected in unit tests.
- Replacements for files other than the main file are assumed to be for headers
and stored as such.
llvm-svn: 184194
To better support per-translation unit replacements, any real work is being
moved out of ActionFactory and into Transform. In this revision, that means
file override application.
For simplification, Transform no longer inherits from SourceFileCallbacks.
TransformTest required updating as a result.
llvm-svn: 184098
This reverts commit r184004.
This test has some dependency on the behavior of the old function on windows. I
added it back to llvm for now.
llvm-svn: 184010
File override structures now contain per-source overrides for headers.
For now, modified headers are written to disk when the Migrator is done.
This is only temporary behaviour since we can expect headers to be
changed by migrating multiple source files. The changes need to be
merged after all migrations are complete.
llvm-svn: 183917
A more flexible container for storing overrides is required for headers. Before
a source goes through the transform pipeline, any headers it references will be
in their original state and unaffected by transforms applied to other sources.
Therefore overrides for headers need to be kept separate for each source file.
This patch doesn't introduce support for storing header overrides yet. It only
replaces the existing structure and makes any necessary changes to support it.
llvm-svn: 183910
Next step toward supporting migrating headers. Instead of using ClangTool's
ability to override all files at once, use a custom FrontendAction and override
only the source (and eventually headers) the action is about to parse.
Use of newFrontendActionFactory() is replaced with a new factory maker provided
by Transform.
llvm-svn: 183855
First step toward supporting header modifications: adding a flag that turns on
such modifications. Eventually header modifications will be on by default but
until all the kinks can be worked out, they must be explicitly enabled.
llvm-svn: 183444
Refactored how global options are passed to Transforms to avoid widespread
changes every time a new global option is added.
Tests updated to reflect new interface.
llvm-svn: 183443
* Documented new command-line options.
* Moved usage to a new page.
* Usage now split into general options and transform-related options.
* Main Migrator page now contains getting started and getting involved
information.
* Also included a JIRA issue collector button for logging bugs.

Performance timers captured in each transform for all files they process are now collected and arranged per source file in preparation for writing to disk.
This revision is the last piece of the initial implementation of performance timer capturing.
llvm-svn: 183274
-Added command line option -report-times to enable or disable the output. The
same option can be used to specify the output directory.
-Write timing data to a unique file in disk using json format.
llvm-svn: 183142
Added a new option -override-macros which causes the, the add-override
transform to detect macros that expand to 'override' (like LLVM_OVERRIDE) and
use these macros instead of the override keyword directly.
llvm-svn: 183001
Using updated form of newFrontendActionFactory(), Transforms now automatically
measure, if requested, how long it takes to apply a MatchFinder to a source
file. Other per-transform overhead, e.g. applying replacements, is not
currently measured. This behaviour is disabled for now and soon will be
connected to a new command line arg.
llvm-svn: 182942
UseAuto used to replace declarion lists with new expressons where some
variable were not initialized with new.
This fix checks that every DeclStmt has a VarDecl with an initializer and it
also ensures that all declarations have the same type.
Added tests for multiple declarations and for typedefs.
llvm-svn: 182736
variables.
UseAuto used to match initialized variable declarations independently of
whether they were defined in a declaration list or as a single declaration.
Now it matches declaration statements where every variable declaration is
initialized.
llvm-svn: 182114
The recent improvement to the Use Nullptr Transform for macro arg
expansions wasn't testing that only allowed NULL macros used in macro
args can be transformed. This revision replaces a TODO to that effect.
Fixes PR15955.
