From: Ulrich Weigand Date: Thu, 30 Jan 2014 18:12:35 +0000 (+0100) Subject: Add support for AT_HWCAP2 auxv entry X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=718ee4dc9b09491707420ae403ad1ce8dfdb61b2;p=binutils-gdb.git Add support for AT_HWCAP2 auxv entry Recent ppc64 Linux kernels provide a new auxv entry AT_HWCAP2, which is currently not recognized by GDB, causing every use of "info auxv" to show an error. This commit adds the AT_HWCAP2 define to include/elf/common.h and handles it in GDB. include/elf/ChangeLog: * common.h (AT_HWCAP2): Define. gdb/ChangeLog: * auxv.c (fprint_target_auxv): Handle AT_HWCAP2. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index e461875f529..d124c7b6549 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,7 @@ +2014-01-30 Ulrich Weigand  + + * auxv.c (fprint_target_auxv): Handle AT_HWCAP2. + 2014-01-29 Jose E.
