Decompilation

[J. Grant]

Hello,

I am currently working on some decompilation methods/ideas. I have been 
looking at the suitability of implementing using the GNU tools as a 
base. I realise this is a very complex process, so would like to ask 
peoples opinions before diving in and coding in all the wrong places.

I would like to achive something similar to the way that gcc is the 
front end for compiling. For each of the stages below I would welcome 
sugested  areas of binutils/GCC that I should focus my work on. I have 
been modifying objdump to produce the intermediate code.  Clearly a lot 
of new code needs to be written to complete this work. If anyone has 
sugestions for the direction I should take this is welcome.

Stage 1: Front end
Input machine code binary
Disassemble
Abstract intermediate code generation
Intermediate code output

Stage 2: Universal decompilation machine (UDM)
CFG generation
CFG analysis
Data Format analysis

Stage 3: Backend HLL target
HLL constructs identified
HLL output

Regards
