Hi Uros:
This patch fix Zhaoxin CPU vendor ID detection problem and add zhaoxin
"lujiazui" processor support.
Currently gcc can't recognize Zhaoxin CPU(vendor ID "CentaurHauls" and
"Shanghai") if user use -march=native option, which is confusing for users.
This patch enables -march=native in zhaoxin family 7th processor and
-march/-mtune=lujiazui, costs and tunning are set according to the
characteristics of the processor.We add a new md file to describe lujiazui
pipeline.
Testing:
Bootstrap is ok, and no regressions for i386/x86-64 testsuite.
Ok for master?
