In the same vein as `PureLLVMPassesPipe`, add a pipe to pypeline that
allows running arbitrarily-specified MLIR passes that do not depend on
the model.
In some cases the uses of a function are not `CallInst`s (e.g.
`ptrtoint`). Since DLA is only concerned with calls, ignore all the
other uses by using the `callers` functions.
When linking globals that are later going to be uniqued by their id,
change their name to a temporary unique value and then restore it
post-linking, this avoids situations where function declarations shared
a common name but not metadata and were merged together by the linker.
Switch from using an array of integers with `ptrtoint` to using an array
of opaque pointers to store globals in an array to prevent their
deletion. This avoids spurious `ptrtoint`s when looking at uses of
globals.
Add a mixin class for piperuns that work on an LLVM module and need
both the model function and the `llvm::Function`. Pipe that inherit this
mixin will receive both the model and LLVM function in the
`runOnLLVMFunction` method.
Change the `Register.*Pipe` functions to end in `Run` if the template
argument should be a pipe run. Also change the concepts `Is.*Pipe` to
also have the `Run` suffix if applicable.
Make the interface required by `SingleOutputPipe` similar to other
piperuns by requiring a constructor, the use of `PipeRunArgument`s and
the implementation of a non-static `run` function.
Contains APIs from upstream LLVM that are not yet present in the current
version, as well as helpers not present in upstream.
See upstream commit 42c31d8302ff8f716601df9c276a5cd9ace6b158.
The `Head` election now works in a bottom-up fashion (child regions are
processed before the parent ones), and ensures that the `Head` election
process is coherent across multiple nested regions.
This means that:
1) The late entries are coherent between the nested regions. If a node
is selected as a late entry for a region, the parent region must
follow this decision too.
2) If a node which is a `Head` candidate for a parent region, is
selected as the `Head` for a child region, the same choice must be
performed for the parent region too.
Before this commit the port number was incorrectly increased when there
were no arguments in a function type, causing edges to be routed in a
less accurate way.
This commit fixes the problem.
