* Show data literal values on instruction hover
Reimplements #108
* Show reloc diffs in func view when data's content differs
Reimplements #153
* Data diff view: Show relocs on hover and in context menu
This reimplements #154
Note that colorizing the text depending on the kind of diff has still not been reimplemented yet
* Fix up some comments
* Data view: Show data bytes with differing relocations as a diff
* Data view: Show differing relocations on hover
* Symbol list view: Adjust symbol/section match %s when relocations differ
* Improve data reloc diffing logic
* Don't make reloc diffs cause bytes to show as red or green
* Properly detect byte size of each relocation
* Data view: Add context menu for copying relocation target symbols
* Also show already-matching relocations on hover/right click
* Change font color for nonmatching relocs on hover
* Show reloc diff in func view when data content differs
* Add "Relax shifted data diffs" option
* Display fake pool relocations at end of line
* Diff reloc data by display string instead of raw bytes
This is to handle data symbols that contain multiple values in them at once, such as stringBase. If you compare the target symbol's bytes directly, then any part of the symbol having different bytes will cause *all* relocations to that symbol to show as a diff, even if the specific string being accessed is the same.
* Fix weak stripped symbols showing as a false diff
Fixed this by showing extern symbols correctly instead of skipping them.
* Add "Relax shifted data diffs" option to objdiff-cli
Includes both a command line argument and a keyboard shortcut (S).
* Remove addi string data hack and ... pool name hack
* Clippy fix
* PPC: Clear relocs from GPRs when overwritten
* PPC: Follow branches to improve pool detection accuracy
* PPC: Handle following bctr jump table control flow
* Clippy fixes
* PPC: Fix extern relocations not having their addend copied
* Add option to disable func data value diffing
* PPC: Handle lmw when clearing GPRs
* PPC: Handle moving reloc address with `add` inst
* Combine "relax reloc diffs" with other reloc diff options
* Add v3 config and migrate from v2

* Fix missing dependency feature for objdiff-gui
* Update .gitignore
* PPC: Display data values on hover for pools as well
* Tooltip data display: Format floats and doubles better
Floats and doubles will now always be displayed with a decimal point and one digit after it, even if they are whole numbers. Floats will also have the f suffix. This is so you can tell the data type just by glancing at the value.
* Move big functions to bottom ppc.rs
* Clear pool relocs in volatile registers on function call
This fixes some false positives.
* Revert ObjArch API changes, add fake target symbol hack
Because we no longer have access to the actual symbol name via sections, guess_data_type can no longer detect the String data type for pooled references.
* Add hack to detect strings via the addi opcode
* Move hack to resolve placeholder symbol into process_code_symbol
* Merge reloc and fake_pool_reloc fields of ObjIns
The Ghidra delinker plugin emits functions with type STT_OBJECT,
rather than STT_FUNC. The current logic was preventing these from
being compared based on their symbol type. Relax this condition
for now.
* Reduce dependencies for no features
* Add missing deps to every feature
* Add missing `dep:`s
* Gate even more deps behind features
Removes dependency on tsify-next / wasm-bindgen unless
compiling with the wasm feature by using `#[cfg_attr]`
* Fix wasm

This allows users to "map" (or "link") symbols with different names so that they can be compared without having to update either the target or base objects. Symbol mappings are persisted in objdiff.json, so generators will need to ensure that they're preserved when updating. (Example: d1334bb79e)
Resolves#117
This re-implements the older algorithm
used for data and BSS section match
percentages. We perform both and
choose the highest match percent
between the two options.
Resolves#84, #85
* Initial ARM support
* Disassemble const pool reloc
* Disasm ARM/Thumb/data based on mapping symbols
* Fallback to mapping symbol `$a`
* Support multiple DWARF sequences
* Update line info
* Rework DWARF line info parsing
- Properly handles multiple sections
in DWARF 1
- line_info moved into ObjSection
- DWARF 2 parser no longer errors with
no .text section
- Both parsers properly skip empty
sections
* Simplify line_info (no Option)
* Get line info from section; output formatted ins string
* Unwrap code section in `arm.rs`
* Handle reloc `R_ARM_SBREL32`
* Update ARM disassembler

This reverts commit 8bbfcc6f453c13340764bbae2946025bc41659ae.
* Update README.md
* Detect ARM version; support ARMv4T and v6K
* Combobox to force ARM version
* Clear LSB in ARM symbol addresses
* Support big-endian ARM ELF files
* Bump `unarm`, `arm-attr`
* Handle ARM implicit addends
* Update README.md
* Explicitly handle all ARM argument types
* Format
* Display more ARM relocs
* Mask LSB on ARM code symbols only
* Read ARM implicit addends
* Format

No more scattered relocation handling and
feature checks. Everything will go through
the ObjArch trait, which makes it easier
to add new architectures going forward.
- Add `objdiff-cli report changes` for diffing two reports
- Unify some click-to-highlight logic between CLI and GUI
- Load .splitmeta section for extra object metadata (original virtual addr, etc)
- More work on objdiff-cli diff
