# FEX - Debugger GUI
|
||
|
|
---
|
||
|
|
FEX has a debugger GUI for debugging the translation of x86 code.
|
||
|
|
This UI is written in [Dear ImGui](https://github.com/ocornut/imgui) since it is purely for debugging and not user facing.
|
||
|
|
|
||
|
|
## Features
|
||
|
|
* Stopping code execution at any point
|
||
|
|
* Single stepping code
|
||
|
|
* ELF code loading
|
||
|
|
* Test Harness code loading
|
||
|
|
* CPU State inspection
|
||
|
|
* IR inspection
|
||
|
|
* CF inspection of IR
|
||
|
|
* Application stderr, stdout viewing
|
||
|
|
* Disassembler for viewing both guest and host code
|
||
|
|
|
||
|
|
## Nice to have
|
||
|
|
* IR writing and direct compiling
|
||
|
|
* Requires writing an IR lexer
|
||
|
|
* Profiling of compiled blocks directly in debugger
|
||
|
|
* Save CPU state prior to running, time compiled block for microprofiling
|
||
|
|
* Save all state to file to allow offline inspection and profiling
|
||
|
|
* Save original code
|
||
|
|
* Save CPU state on entry
|
||
|
|
* Save IR
|
||
|
|
* Save compiled host code
|
||
|
|
* Profiling data
|
||
|
|
* Allow comparison of all state before(What was saved to file) and after (New version compiled in this version of FEX for iterative debugging)
|
||
|
|
* Single stepping of IR state and inspection of SSA values
|
||
|
|
* Complete disconnection of debugger from FEXCore to ensure robustness if core crashes.
