Hi all,

This patch aims to mention newly added Intel ISA and march support.

Ok for trunk?

Here and in the other cases I'd skip "to GCC". This is clear from the
context (this being the GCC release notes :-) and makes it shorter.

[Jiang, Haochen]

Hi Gerald,

I will remove "to GCC" here if there is no more comment from others on Thursday.
For me it is reasonable.

Thx,
Haochen
