Some files had discordant executable bit presence and shebang presence.
This commit fixes these occurrences by adding removing the required
feautures where needed.
This commit introduces `BasicBlockID` as the unique identifier for a
`efa::BasicBlock` into the CFG. A `BasicBlockID` is defined by a
`MetaAddress` plus an incremental integer. This enables us to have
multiple instances of the same block in a single function, which is
particularly useful when inlining multiple times the same function.
Apart from this, the commit also does the following:
* It drops representing `MetaAddress`es a `structs` in the IR. This created
several issues related to ABI. We now represent them as strings.
* It defines more functions in `support.h`, instead of defining prototypes
by hand in `CodeGenerator.cpp` and the like. Specifically, `unknownPC`
and `raise_exception_helper`. We also introduce a C "constructor" for
`PlainMetaAddress`.
* It significantly reduces the API of `GeneratedCodeBasicInfo`, which
was supposed to be put on a diet since a long time. Specifically,
many jump target related methods have been moved to free functions in
`IRHelpers.h`. Also `GCBI::getSuccessors` has been pushed into its
only user, `PruneRetSuccessors`, to prevent further usage of a
deprecated API. In the future, it would be nice to drop it entirely.
* It introduces `efa::BasicBlock::InlinedFrom`.
* Introduce an enum to represent named argument indices for `newpc`.
This enables us to more effectively manipulate its argument list.
* It improves the verification and error reporting for
`efa::FunctionMetadata`.
* Update tests.
This commit is preliminary to another piece of work to improve the
generality of inlining beyond the simple "fake function" scenario, for
which the feature was originally conceived.
Running `revng daemon-self-test` runs steps and analyses that are part
of downstream projects, leading to unexpected and unstable results.
We can still run this downstream.
We can re-enable this once we can run it on a specific step and with a
custom set of analyses.
This new command will, given an executable, try to produce all
artifacts. By default it will run `revng daemon`, however an external
address can be provided to test remote daemons, e.g. running inside a
container.
Drop the use of requests in the daemon tests, use aiohttp instead as
it allows the use of unix sockets, which simplifies the creation of
multiple ephimeral daemons
