New submission from STINNER Victor <vstin...@python.org>:

When Python is configured with:

   ./configure --enable-optimizations

PGO is enabled but not LTO.

I recall that a few years ago, GCC with LTO had bugs. But now, GCC with LTO is 
reliable. I suggest to enable it by default in Python 3.11.

Or did I miss a reason to not do that?
