This introduces a new datatype CValue for representing constants
in Macaw programs, modifies the existing Value datatype to use then,
and introduces patterns for compatibility with existing datatypes.
The patch also updates the function argument analysis to use more
explicit argument passing rather than monadic updates. The intent is
to help clarify when data is initialized rather than updated.
Finally this updates a README and does some minor updates.
This primarily refines the abstract state propagated to branch
pairs. It was needed on the ARM platform to support the IT blocks
with the changes to the Core representation in macaw-base 0.3.6.
This also includes a few simplifications added and comment
improvements.
This update renames many of the declarations exported by
Data.Macaw.Memory so that we have more consistent names.
The majority of the existing names are now exported with DEPRECATION
warnings. Some of the symbol declarations that were not used by the
Memory datatype have been moved to other modules.
The minor version of macaw-base has been incremented.
This patch adds initial support for relocations in Macaw code
discovery, and adds other refactoring.
* It introduces a SymbolValue constructor to represent references to
symbols within Macaw.
* The various cases for x86 mov are made explicit after the flexdis refactor
broke the previous code. We should now support segment register movs and
give better error messages when seeing mov with control or debug registers.
* The generic exception operation is replaced with Hlt and UD2 terminal
x86-specific statements.
* CodeAddrReason is split into FunctionExploreReason and BlockExploreReason to
clarify whether a function or block was discovered.
* The Macaw pretty printer is changed to use write_mem in place of pointer syntax.
* Various other refactoring is made to clarify code.
