Handling of command line options that specify paths for output files
have been improved in the following ways:
- If the CDecompilerPass is not default-constructed, it already has a
reference to the stream where outputs must be written. In this case,
it is wrong to use a command line option to specify the output
directory. If this happens the program is now able to detect it and to
terminate with an error.
- If some of the specified paths is not found or has the wrong
permission, the program fails early.
- On program failure because of one of the above safety checks, the
program terminates with an informative error message.
This means that they can be specified only once on the command line.
If they are specified more than once, the program fails with an
informative error.
This commit fixes the detection of the revng-c include file in build
directory, using the PathList facility provided by revng.
Before this commit, running revng-c from build directory failed to
properly identify the revng-c include if it was not already installed
but only available in the build directory itself.
Add a flag to enable the decompilation of a single function.
In order to have a single flag shared between the `RestructureCFGPass`
and the `CDecompilerPass`, we added a new dedicated decompilation unit
called `TargetFunctionOption`.
Replicate the changes made by this commit
f2a0df309f78e1b5d7c5f81ada5110523644559e perfomed by Pietro on the
branch containing the development fixes for `revng-c`.
Collection of the metrics related to the short circuit and trivial short
circuit simplification. The metrics are computed directly during the
beautify pass and later serialized on a .csv file.
Dropped the use of a temporary file containing the necessary includes
for clang-tooling to work correctly (at the moment `#include <stdint.h>`
) in favor of a single file which is installed in `root/share/revngc`
and used by clang-tooling.
If the `-decompiled-prefix` is passed to the `revng opt` command the
decompilation pass takes care of serializing the decompiled code of each
function in a different file.
The filename is composed by the prefix string passed as parameter and by
the function name.
`BasicBlockNode` and `RegionCFG` classes are now template classes. This
means that the `BasicBlockNode` class can be used as a generic wrapper
for any type of object in the original graph (it is usually used to wrap
a `llvm::BasicBlock *` for decompilation purposes, but in tests it can
be used to wrap a `DotNode` object) that implementes `GraphTraits`.
Removed the computation of the information contained in the
`NDuplicates` prevously done in the `MarkForSerialization` pass, since
the information is now precomputed in the `RestructureCFG` pass and
exposed with a dedicated method.
