arc: Add support for ARC HS extra registers in core files
When a coredump is generated, there are a few registers in
ARC HS that are put under a special section, namely ".reg-v2".
It is for backward compatibility reasons with older tools that
we have decided not to extend the generic ".reg" section.
This patch makes it possible to display the information better
regarding that section. Compare the output of "readelf" without
and with these changes:
$ readelf -n core # without the patch
...
LINUX 0x0000000c Unknown note type: (0x00000600)
description data: 78 08 00 00 2f 6c 64 2d 75 43 6c 69
$ readelf -n core # with the patch
...
LINUX 0x0000000c NT_ARC_V2 (ARC HS accumulator/extra registers)
description data: 78 08 00 00 2f 6c 64 2d 75 43 6c 69
In another commit (soon to be submitted), GDB will makes use of these
changes to parse the extra section and its registers.
