Mark Langen e638d0b17a Implementation of basic data flow analysis for PowerPC (#212)

* Show string constants inline
* Handle calls to MWCC "sled" helpers which otherwise disrupt flow analysis

* Run cargo insta review

* Apply clippy feedback

* Update more tests.

* Remove std use from ppc flow analysis

* Try to make wasm build work again

* More test changes

* Probably last wasm fix

* Formatting

* Fix WASM

* One more clippy thing

* Fixed display of float constants in a LFS or LFD instruction in case where there is a branch to the subsequent instruction with a different register value.

LagoLunatic 2876be37a3 Show relocation diffs in function view when the data's content differs (#153)
* 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

LagoLunatic 9ab246367b Add buttons to collapse or expand all sections in the symbol list view for an object simultaneously (#149)
* Add buttons to expand/collapse all sections to symbol list view

* Add buttons to expand/collapse all sections to the split view

LagoLunatic 10b2a9c129 PPC: Display data values on hover for pools as well (#140)
* 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

LagoLunatic abe68ef2f2 objdiff-gui: Implement keyboard shortcuts (#139)
* Fix missing dependency feature for objdiff-gui

* Update .gitignore

* Add enter and back hotkeys

* Add scroll hotkeys

* Add hotkeys to select the next symbol above/below the current one in the listing

* Do not clear highlighted symbol when backing out of diff view

* Do not clear highlighted symbol when hovering mouse over an unpaired symbol

* Auto-scroll the keyboard-selected symbols into view if offscreen

* Fix some hotkeys stealing input from focused widgets

e.g. The symbol list was stealing the W/S key presses when typing into the symbol filter text edit.

If the user actually wants to use these shortcuts while a widget is focused, they can simply press the escape key to unfocus all widgets and then press the shortcut.

* Add Ctrl+F/S shortcuts for focusing the object and symbol filter text edits

* Add space as alternative to enter hotkey

This is for consistency with egui's builtint enter/space hotkey for interacting with the focused widget.

* Add hotkeys to change target and base functions

* Split function diff view: Enable PageUp/PageDown/Home/End for scrolling

* Add escape as an alternative to back hotkey

* Fix auto-scrolling to highlighted symbol only working for the left side

The flag is cleared after one scroll to avoid doing it continuously, but this breaks when we need to scroll to both the left and the right symbol at the same time. So now each side has its own flag to keep track of this state independently.

* Simplify clearing of the autoscroll flag, remove &mut State

* Found a better place to clear the autoscroll flag

DiffViewState::post_update is where the flag gets set, so clearing it right before that at the start of the function seems to make the most sense, instead of doing it in App::update.

Luke Street 741d93e211 Add symbol mapping feature (#118)
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: https://github.com/encounter/dtk-template/commit/d1334bb79e71af1a7b3b090bffda4adc483f722c)

Steven Casper a43320af1f PPC: Guess reloc data type based on the instruction. (#108)

Adds an entry to the reloc tooltip to show the inferred data type
and value.

* Fix clippy warning

* Match on Opcode rather than mnemonic string
