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 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. | |
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. | |
15 | ||
16 | # Configuration ABI OS ABI version | |
17 | # ------------- ------ ----------- | |
18 | ||
19 | .*-.*-linux.* 0 2.0.0 # earliest compatible kernel version | |
20 | ||
21 | .*-.*-gnu-gnu.* 1 0.0.0 | |
22 | ||
23 | # There is no catch-all default here because every supported OS that uses | |
24 | # ELF must have its own unique ABI tag. |
