We have specific diff logic that relies on knowing
which object is the target object, and which is the
base. generate_mapping_symbols was designed in such
a way that it would reverse the target/base, leading
to a match percent shown that's different when it
gets applied.
Fixes#200
* 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
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
* Update README.md
* Format
* Revert "Update README.md"
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.
