* dwarf_formudata needs special treatment.
This is now on the branch. The new function is called __libdw_read_udata_address. There's a mismatch between what the function does and what the code in dwarf_ranges looks like, I need to look that some more tomorrow.
Doing the above, I found myself looking at dwarf_getmacros. The way offsets are handled in this functions strikes me as wrong: macoff is read from attribute, and then never used; instead, readp is formed as d_buf + offset, where offset is an argument passed into the function (seems to be for purposes of iteration restarts). readendp is then computed as readp + d_size, which is definitely wrong. Our test suite doesn't cover this function (AFAIK, GNU toolchain doesn't even emit macinfo section). Seems like something that should be fixed. I can look at it tomorrow, on separate branch. Right now I'm leaving it alone.
Thanks, PM
