| # 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. |
