PR c++/86485 - -Wmaybe-unused with empty class ?: · 507318f1

The problem in this testcase is that the front end expects an rvalue
COND_EXPR to initialize a single temporary from one of the arms.  But
because gimplify_cond_expr used MODIFY_EXPR, instead the arms would each
create their own temporary and then copy that into the common temporary.

So, let's use INIT_EXPR instead.

re PR c++/86485 ("anonymous" maybe-uninitialized false positive with ternary operator) · dbcd32f8

	* class.c (is_really_empty_class): Add ignore_vptr parm.

While looking at PR86485, I noticed that many uses of is_really_empty_class
were overlooking that it returned true for a class with only a vptr;
initialization of such a class is not trivial.  Marek's P1064 patch fixed
one place in constexpr.c to also check for a vtable, but there are several
others that still don't.

This patch requires callers to explicitly choose which behavior they want.
Currently the uses in constexpr.c want to consider the vptr, and other uses
don't.

	(trivial_default_constructor_is_constexpr): Pass it.

sysinfo: add Flags to Statfs_t if not already there · 9bf54c93

If there is no f_flags field in statfs_t then rename one of the
f_spare fields, as happened in Linux kernel version 2.6.36. This
fixes the build on CentOS 5.11. The CentOS kernel will hopefully not
fill in the f_spare field, so the resulting flags will be zero.

Define midpoint and lerp functions for C++20 (P0811R3) · 24387442

The implementation of midpoint used for integral types is due to Howard

[ARM] Fix PR89222 · d7c50d67

The GCC optimizer can generate symbols with non-zero offset from simple

to true.  The fix is to disable offsets on function pointer symbols.
