# 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 tag values we use are 32-bit quantities stored in machine byte order.
|
|
# Conventionally the high-order byte indicates the OS and the low three
|
|
# bytes form a version number associated with a particular ABI version.
|
|
|
|
# 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
|
|
|
|
# There is no catch-all default here because every supported OS that uses
|
|
# ELF must have its own unique ABI tag.
