[Elftoolchain-developers] elfdump -Sd formatting (Solaris)

[Richard P. <ri...@ne...>]

Checking out 0.7.1, I notice in general that the tags output under
the Solaris elfdump  format maintain the 'DT_' prefix, as follows:

Is there any particular reason this needs to be different, or would 
a patch to align more closely with the Solaris format be okay?

It could be noticed that there are actually at least four issues above:
1. tag formatting, 'DT_' prefix not suppressed
2. some missing SUNW_ tags not formatted
3. some missing output information (NB: DT_RUNPATH is already submitted,
   but look at DT_CHECKSUM, DT_RELCOUNT, DT_SYM* and DT_FLAGS*)
4. DT_NULL output format compression using a range ([41-50])
