Hi Uros,
This patch fix Zhaoxin CPU Vendor ID detection problem
and add Zhaoxin "lujiazui" processor support and tuning.
Currently gcc can't recognize Zhaoxin CPU (Vendor ID "CentaurHauls" and
"Shanghai")
and wrongly identify Zhaoxin "lujiazui" as Intel core2 or i386, which is
confusing for use
When building a const to a reg, it may need a few instructions.
This patch updates rs6000_rtx_costs to make it more accurate for

With this patch, cse.cc could get accurate cost for complex

Hi Guys,
Attached is a proposed patch to fix another Rust demangling bug
reported in PR 105039. I would like to say that this is the
last time that we will see this problem for the Rust demangler,
but I am not that naive...
OK to apply ?

This is a regression present on mainline, 11 and 10 branches. When the serial
port is closed, we need to ensure that the port handle is properly reset for
it to be detected as closed.
Tested on x86-64/Linux, applied on mainline, 11 and 10 branches.
