# This file defines the ABI tag value we will use in the ELF note included # in the startup code to be linked into every program. # The following lines list regexps matching canonical configurations, and # the associated ABI tag values. The entire list is processed, with # earlier entries taking precedence over later entries. So loose patterns # at the end of the list can give defaults. # The ABI tags we use are four 32-bit integers. The first of these # is the operating-system number, the next three are the revision number # of the first compatible kernel. # After the configuration regexp, four integers in C syntax appear # surrounded by any whitespace or punctuation, one for each byte, MSB first. # Configuration ABI OS ABI version # ------------- ------ ----------- .*-.*-linux.* 0 2.0.0 # earliest compatible kernel version .*-.*-gnu-gnu.* 1 0.0.0 .*-sun-solaris2.* 2 2.0.0 # just an arbitrary value .*-.*-freebsd.*-gnu.* 3 4.0.0 # earliest compatible kernel version .*-.*-knetbsd.*-gnu.* 4 1.6.0 # earliest compatible kernel version .*-.*-syllable.* 5 2.0.0 # just an arbitrary value # There is no catch-all default here because every supported OS that uses # ELF must have its own unique ABI tag.
