`-fvisibility-inlines-hidden` ensures that each dynamic library uses its
own version of each `inline` function.
This reduces the number of exported symbols and resolves issues related
to picking a version of a weak symbol that has already been deleted upon
`dlclose`.
The downside of this flag is that the address of `inline` functions can
be different across different libraries. This commit drops certain
assertions that were relying on this behavior.
Add a new key to a Step, named Artifacts. If present, it indicates that
the step has a "default" Kind and Container that can be easily retrieved
without explicitly specifying either when producing an artifact.
Add additional field MIMEType to Container.
This allows API consumers to know at runtime how to treat the data
within a container without any prior knowledge.
Adds missing API functions to PipelineC that will be needed by the
GraphQL API:
* Kinds enumeration
* Get Rank and parent of a Kind
* Enumerate and inspect Ranks
* Get a Step's parent
Included are some docstring fixes
This library contains what were previously 6 separate libraries:
- FilterForDecompilation
- MakeEnvNull
- RemoveCpuLoopStore
- RemoveExceptionCalls
- RemoveLLVMDbgIntrinsics
- RemoveREmoveNewPCCalls
These libraries are now aggregated, and will be merged in single
llvm::Pass for migrating revng-c to the new revng pipelines
infrastructure.
For now they are unused, but they will be used by the first
revng-c pipeline using revng::pipeline, that will strip off all the
artifacts left from the lifting process.
This pass was used to remove llvm.addume(false) calls that caused some
paths of the CFG to be marked as unreachable and optimized away.
The insertion of calls to `llvm.assume(false)` calls was happening due
to the handling of the PC around `opaquepc` calls, generated by `revng`.
The calls to `opaquepc` are no longer emitted by `revng`, nor is the
special handling of the PC around them that causes `llvm.assume(false)`
calls to be emitted.
Hence, the RemoveLLVMAssumeCalls pass to no longer makes sense. This
commit removes it.
This library replaces the old AddIRSerializationMarkers, cleaning up a
lot of historcal baggage, merging Liveness and MarkAnalysis, and
adopting a more accurate naming across all the codebase.
These two parts of the code needed to be separated into libraries
because they were used both by the old C backend and by
IRCanonicalization.
Now that the old C backend is dead, they have been incorporated into
IRCanonicalization.
Further changes are necessary to strip away the last leftovers of the
old C backend from MarkAnalysis.
Change company name to "rev.ng Labs Srl" in all license headers
to reflect changed company name and legal status
Add missing license headers to files that didn't have one
Split the interface into two functions: `enforce.*` returning the map by
value and `tryApply.*` returning an `std::optional`.
Improve non-positional single deduction function to better reflect
some corner cases (for example how a required `NoOrDead` register
argument is handled).
Enforce a position-based deduction corner case where it's impossible to
deduce whether the argument is passed in the GPR or the vector one -
now GPR takes precedence in those cases.
