abi-tags

   1 # This file defines the ABI tag value we will use in the ELF note included
   2 # in the startup code to be linked into every program.
   3
   4 # The following lines list regexps matching canonical configurations, and
   5 # the associated ABI tag values.  The entire list is processed, with
   6 # earlier entries taking precedence over later entries.  So loose patterns
   7 # at the end of the list can give defaults.
   8
   9 # The ABI tags we use are four 32-bit integers.  The first of these
  10 # is the operating-system number, the next three are the revision number
  11 # of the first compatible kernel.
  12
  13 # After the configuration regexp, four integers in C syntax appear
  14 # surrounded by any whitespace or punctuation, one for each byte, MSB first.
