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.
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.
9 # The ABI tag values we use are 32-bit quantities stored in machine byte order.
10 # Conventionally the high-order byte indicates the OS and the low three
11 # bytes form a version number associated with a particular ABI version.
13 # After the configuration regexp, four integers in C syntax appear
14 # surrounded by any whitespace or punctuation, one for each byte, MSB first.
16 # Configuration ABI OS ABI version
17 # ------------- ------ -----------
19 .*-.*-linux.* 0 2.0.0 # earliest compatible kernel version
21 .*-.*-gnu-gnu.* 1 0.0.0
23 sparc-sun-solaris2.* 2 2.0.0 # just an arbitrary value
25 # There is no catch-all default here because every supported OS that uses
26 # ELF must have its own unique ABI tag.
