AArch32: Support conditional returns (#243) Adds support in macaw-aarch32 for conditional returns. These are not supported in core macaw, and are thus architecture-specific block terminators. This required changes to the type of arch-specific block terminators. Before, `ArchTermStmt` was only parameterized by a state thread (`ids`). This meant that they could not contain macaw (or crucible) values. Some work on. AArch32 requires being able to store condition values in arch terminators (to support conditional returns). This change modifies the `ArchTermStmt` to enable this, which requires a bit of plumbing through various definitions and some extra instances. In support of actually using this, it also became necessary to plumb fallthrough block labels through the architecture-specific terminator translation in macaw-symbolic. Note that this change was overdue, as the PowerPC backend was storing macaw values in a way that would have rendered them unusable in the macaw-ppc-symbolic translation, had any interpretation been provided. These new changes will enable a handler to be written for the conditional PowerPC trap instructions. PowerPC, x86, and ARM have been updated. Improves the macaw-aarch32 tests. There is now a command line option to save the generated macaw IR for each discovered function to /tmp. Note that this reuses some infrastructure from the macaw-symbolic tests. This shared functionality should be extracted into a macaw-testing library.

### Features
Consistently use symbol table functionality from elf-edit This: * Bumps the `elf-edit` submodule to bring in the changes from GaloisInc/elf-edit#34. * Updates `Data.Macaw.Memory.ElfLoader` to consolidate the symbol table logic with the corresponding functions from `elf-edit`. Fixes #277.

- `resolveElfContents`, as well as related functions in
`Data.Macaw.Memory.ElfLoader`, now compute dynamic function symbols for
non–position-independent executables. These were previously omitted due to
an oversight in the implementation.
`macaw-base`: Resolve PPC{32,64} relocations This builds on top of the work in https://github.com/GaloisInc/elf-edit/pull/41. For now, I only add support for a select few relocation types, leaving the rest as future work.
2023-11-02 18:58:04 +03:00
- Add support for PPC32 and PPC64 relocations in `Data.Macaw.Memory.ElfLoader`.

### API Changes
- Architecture-specific block terminators can now contain macaw values
This changed the type of the architecture extension block terminators from `ArchTermStmt ids` to `ArchTermStmt f` where `f ~ Value arch ids` at the macaw level.
- Architecture backends can now configure the block classification during the discovery phase
The interface to configure block classification is exposed through the `ArchitectureInfo`. Note that clients that have not created their own `ArchitectureInfo` from scratch should be unaffected (which is the vast majority).
- The post-discovery AST types are now exported from `Data.Macaw.Discovery.ParsedContents`
It is recommended that future references to these types be done through this module. They are re-exported from their original location (`Data.Macaw.Discovery.State`) for backwards compatibility. One day that is likely to change.
Adapt to dynSymEntry being definition-aware in elf-edit This bump the `elf-edit` submodule to bring in the changes from https://github.com/GaloisInc/elf-edit/pull/29, which adds an additional `VersionDefMap` argument to `elf-edit` to make it aware of version definitions. This requires some changes to the API in `Data.Macaw.Memory.ElfLoader` to accommodate.
2022-04-18 15:52:29 +03:00
- The `DynamicSymbolTable` constructor of `Data.Macaw.Memory.ElfLoader`'s
`SymbolTable` data type now has an additional `VersionDefMap` field, which is
needed for finding versioning information in some cases.
macaw-base: Document hashable-related API changes
2023-02-21 01:49:17 +03:00
- The `Hashable` and `HashableF` instances for `App f` now require
`TestEquality f` constraints. (This is needed to support `hashable-1.4.*`,
which adds `Eq` as a superclass to `Hashable`.)
