So: Sorry for the noise on the list.

According to PR4131, there is currently no solution for this issue. The
".rodata" placement would be highly desireable for my current projects.
This means that I would be willing to try to implement the required
enhancements myself.

Since so far I know only about how the back-ends work, I'd appreciate a
hint on where to start, which part of the code to look at, etc. .

Of course, it's best if this can be implemented in the compiler, but if the size and the number of the readonly data is manageable, you can do this by hand - inspect what the layout of the class is by writing a test program and looking at how the fields are layed out, and replicating the same data in the assembly. -- #pragma ident "Seongbae Park, compiler, http://seongbae.blogspot.com";
