Introduction
------------
Desquirr is a decompiler plugin for IDA Pro. It is currently capable of simple
data flow analysis of binaries with Intel x86 machine code.
This program is currently under development. Suggestions, bug reports and
patches are welcome.
For more information, please visit this web site:
http://desquirr.sourceforge.net/
Installation and configuration
------------------------------
1. Copy desquirr.plw to the plugins subdirectory in your IDA Pro installation
2. Edit plugins.cfg (optionally) to get different kinds of decompilation:
Decompile_to_C desquirr Ctrl+F9 0
Decompile desquirr Ctrl+F10 1
Limitations
-----------
The limitations are not limited to this list :-)
o Only decompiles one function at a time
o Does not handle all types of instructions
o Does not handle DX:AX or EDX:EAX very well
o Does not handle register variables properly
o Leaves pop statements in the end of functions
o Lots of code is inlined in the .hpp files but should be moved to the .cpp
files
