RFC: Collecting together binary file attributes into a single file.


Hi Guys,

  All I wanted to do was to make GCC's ARM assembler output slightly
  easier to read...

  I would like to propose a patch to create a new header file in the
  include/ directory.  This file would contain enums describing the
  attributes that be can found in SHT_GNU_ATTRIBUTES sections.  The
  purpose of the file is to provide a single place where these values
  are defined, and to share the information between GCC, BINUTILS and
  GDB.

  The patch also includes an update to readelf to make it use the
  enumerated values and an example of a patch to the ARM backend of GCC
  to include the attribute names in its assembler output.


  So - what do people think ?  Any objections to this idea ?

Cheers
  Nick
