v2 Changes:
1. Enable proportion orig_sum to the new nodes for self recursive node:
new_sum = (orig_sum + new_sum) \
* self_recursive_probability * (1 / param_ipa_cp_max_recursive_depth).
2. Add value range for param_ipa_cp_max_recursive_depth.
The performance of exchange2 built with PGO wil

Hi,
here are some of changes of LTO/IPA done in GCC10. There is also
recursive cloning and some other stuff I will add incrementally as well
as some data on overall compile time/memory use improvements as we
reported in past years. I am still running tests and fixing bugs in this
area.

This patch fixes an awkward corner case in which:
(a) we apply if-conversion to a loop;
(b) the original scalar loop doesn't have a vdef, and thus doesn't
need a virtual phi;
(c) the vectorised main loop does need a vdef and a virtual phi (see below);
(d) we also vectorise the epilogue; and

Hi,
This patch fixes ICE on invalid code, specifically files that have
conflict-marker-like signs before EOF.

A recent change to target.c introduced the UINTPTR_MAX define. This exposed
the fact that
defines for INTPTR_MAX and UINTPTR_MAX are incomplete, and the define for
SIZE_MAX is missing
on hpux11.11.

Thanks, "1" means no recursive cloning but only constant propagation from
caller to callee in your code?
