[Soot-list] How to transform a Grimp file into class file

[Bodden, Eric]

Hi.

Please try the -via-grimp option:

This should give you GrimpBody instances in general, which can then hold Grimp instructions.

Cheers,
Eric

Therefore, the generated jimple file contains statements containing more than three operators. When I transform the generated Jimple into class, I got the following error.

Or I simply shouldn't use the Grimp.v().newXXX() functions in the jtp transformation step? I know I can transform the generated expressions into jimple standard three operator format. However, I just want to see if there's any quicker way as I tried.
