Add support for AT_HWCAP2 auxv entry
|
|
|
7ab123 |
|
|
|
7ab123 |
Recent ppc64 Linux kernels provide a new auxv entry AT_HWCAP2,
|
|
|
7ab123 |
which is currently not recognized by GDB, causing every use of
|
|
|
7ab123 |
"info auxv" to show an error.
|
|
|

This commit adds the AT_HWCAP2 define to include/elf/common.h
|
|
|
7ab123 |
and handles it in GDB.
