Before this commit, when outlining parts of `root` for analysis
purposes, we used to replace calls with a set of instructions clobbering
the set of register *not* preserved by such call, or, in case the
prototype was not available, by the default prototype.
This commit forces the usage of the default prototype.
This trades off precision with accuracy but we get the lift pipe not to
depend on any model::Function prototype.
This commit introduces new tags to specify how LLVMContainer should
deduplicate sets of equivalent functions, typically managed by an
`OpaqueFunctionPool`.
This method enables pipes to specify a custom invalidation logic. This
change enables us to supress automatic model tracking in certain parts
and then handle the consequences by hand.
Make sure you read the TODO before using this.
This commit introduces a function to obtain the name assigned to a
`llvm::Function` associated to a `model::Function`. This simplifies the
codebase but also enables us to introduce an option to produce
human-friendly names for debugging/testing purposes.
Before this commit, we used to attach to call site a metadata to trace
back the call site to the CFG (i.e., `FunctionMetadata`).
This led several passes in revng-c to depend on `FunctionMetadata` just
for this.
This commit, attaches to call sites a reference to the prototype itself
(on the `revng.prototype` metadata), breaking many of such dependencies.
This comit propagates the deduced info about inputs and outputs of pipes
all the way up to the runner, so that the requested output of a pipe can
be passed to its invocation.
In the `type` function, if a file is present in the index then it should
also be checked in the bucked via a HEAD call. This allows revng to
successfully start up even if a file in the `index.yml` files has been
deleted on S3.
