In this commit we instruct the build system to use the unified schema
files instead of collecting the `TUPLE-TREE-YAML` comments.
The fixes to C++ files are necessary because they depend on the order
of the fields in the schema, which was changed.
This pass wraps LLVM's vanilla InstCombine, to hijack one of its
options. The goal of this hijack is to prevent InstCombine from
splitting and replacing accesses to arrays with GEPs and smaller
accesses.
This pass wraps LLVM's vanilla SROA, to hijack one of its options.
The goal of this hijack is to prevent SROA from splitting and replacing
memory accesses to arrays with GEPs and smaller accesses.
This will be used to collect various customizations of LLVM passes, that
are necessary to enable setting different default options to passes for
insertion in the revng pipeline.
This reduces the occasions where some LLVM optimization passes rewrite
the allocas, reducing the chances that the model type metadata is
discarded by LLVM passes that we don't control.
A pass that was doing this was InstCombine.
Not checking for primitives there doesn't change anything anyway, as
`purge-invalid-types` model pass will clean anything invalid still
left after the importer.
Because of how name builders used to lazy gather namespaces on the first
requested name, the objects were self mutating. As such only non-const
references could be used to pass them around.
Since that is no longer the case, this restores most of lost const
qualifiers.
This reworks NameBuilder to ease the transition to the system where
the model will be guaranteed to never contain any name collisions, both
between user-specified names and the automatic ones.
