Yes, I update -mhreset in x86gprintrin-{1,2,3,4,5}.c

We will check-in the attached patch. Thanks.

The patch doesn't include all testsuite changes.

Otherwise OK.

[Patch] x86: Enable GCC support for Intel Hreset extension

2020-10-13 Thread Hongyu Wang via Gcc-patches

Hi:

This patch is about to support Intel Hreset instruction.

Hreset provides a hint to the processor to selectively reset the prediction
history of the current logical processor.

For more details, please refer to
https://software.intel.com/content/dam/develop/external/us/en/documents/architecture-instruction-set-extensions-programming-reference.pdf

Bootstrap ok, regression test on i386/x86 backend is ok.

OK for master?
