Background:
Chengdu Haiguang IC Design Co., Ltd (Hygon) is a Joint Venture between
AMD and Haiguang Information Technology Co.,Ltd., aims at providing high
performance x86 processor for China server market. Its first generation
processor codename is Dhyana, which originates from AMD technology and
shares most of the architecture with AMD's family 17h, but with
different CPU Vendor ID("HygonGenuine")/Family series number(Family
18h).
gdb/ChangeLog:
* go32-nat.c (go32_sysinfo): Add hygon_p.
The results of make check are no degradation:
=== binutils Summary ===
of expected passes 251
of unresolved testcases 1
of unsupported tests 1
Please let me know your comments.
Thanks in advance.
