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

compilation database stuff)
* add EXAMPLES section

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
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
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
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
Files containing the list of paths to be included and excluded can now be
specified through -include-from=<filename> and -exclude-from=<filename> command
line options in cpp11-migrate.
Added support for data files for cpp11-migrate unittests. The Cpp11MigrateTests
executable just requires a DATADIR environment variable to be set which
specifies the directory where data files are stored. This is handled
automatically when using LIT.

This commit adds initial support for the -include/-exclude options which are
both currently marked as hidden. This support is the first step toward
supporting transformations in headers included from source files.
Added unittests to test include/exclude support.

With cpp11-migrate core functionality moved to a separate library (for enabling
unit tests) this library contained code that referenced symbols that are still
in the main binary. On some platforms, the shared library build broke as a
result. This revision fixes the dependency problem and is safe for the eventual
lib-ification of the transforms as well.
llvm-svn: 178901
Summary:
Transform.* and Transforms.* moved to form a new library: libmigrateCore.
#includes updated to point to new header locations.
To support autoconf build, Cpp11Migrate.cpp moved to new subdirectory 'tool'
which also contains build files for creating final binary.
CMake and autoconf updated to build the new library and link it with
cpp11-migrate and with cpp11-migrate unit tests.
Dummy unit tests replaced with simple, but real, tests for Transform's public
interface.
TODO: Lib-ifying the transforms to further simplify build of cpp11-migrate.
