sys::fs::make_absolute was turning '.' into '<path>/.' which broke prefix
comparison logic. Stripping these extra chars fixes the problem.

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.

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.

r183989 added a dependency on LLVMOption in clangFrontend.

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

Moving RewriteContainer's constructor impl to Transform.cpp to reduce clutter.
More things will soon be added to this header.

llvm-svn: 183856

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

llvm-svn: 183785

llvm-svn: 183784

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.

Getting PIDs on Windows is broken. Proper fix is simple but requires testing so
just disabling PID-based file names for now.

llvm-svn: 183154

-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: 182957

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.

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

UseAutoActions.cpp:48:17: error: redefinition of 'E' with a different type.

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.

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.

llvm-svn: 182014

Several free functions related to macro arg testing are being moved into
CastSequenceVisitor to facilitate upcoming fix.

This commit fixes a "FIXME" in the add-override transform. ' override' was
misplaced when a comment was between the function body and the end of the
'prototype'.

It also remove duplicated check for the main file from the last commit (and
fixes the typo in the comment above).

llvm-svn: 181806

This patch fixes different issues:
- override is not added in template 'contexts' (this will be further improved
  to handle safe situations, a test for this has been written already)
- the main file is now checked before the modifications are applied
- override is not applied now when dealing with pure methods since it was
  misplaced (ignoring it isn't the perfect solution but it seems difficult to
  find the location just before the pure-specifier)

Fixes PR15827
