e638d0b17a Implementation of basic data flow analysis for PowerPC (#212)
* WIP implementation

* * Move flow analysis to dedicated file
* 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.

* On lines with a reloc, only hide Symbol type data flow values rather than all data flow values.

* Formatting

07ef93f16a Ignore extern symbols with symbol name lookups
When searching for a symbol by name, only look at
symbols that are defined within the object,
ignoring extern symbols (symbols without section).

Fixes #181

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
