There are significant users of the ELF analysis capabilities (e.g. for security vulnerability research). Unfortunately, its usefulness is quite limited.

I noticed the following problems:

  • full search returns the binaries which match but the highlighting is missing completely in the results (with source code search the symbol matching the search terms is highlighted in bold)
  • symbol names cannot be found using 'Definition' search
    • this should be possible using the Shndx as reported by nm(1) (number is definition, UNDEF is just reference to symbol in another library)
    • the Reference search should use this information so that we can search for references to symbols
  • clicking on the library name leads to unformatted text output

Screenshots which illustrate some of the above problems are attached.
