shifted). rl[wd]imi is one of our very few insns that has the outpu

This usage was intended to be allowed by P2128, but it didn't make it into
the final wording. Fixed by CWG 2507.
Tested x86_64-pc-linux-gnu, applying to trunk.

To display (o-,i-)stringstreams in the common case, we just print the
underlying stringbuf, without the many ios_base members. In the
unconventional case that the underlying streambuf was redirected, we
report the redirected target.

C2x follows C++ in making alignas, alignof, bool, false,

This is the 4th version of the patch set.
Compare to the 3rd version, the following are the major change:
1. delete all the warnings for the confliction between -std and
-fstrict-flex-arrays per our discussion.
2. delete all the related testing cases for these warnings.
3. update all the wording c
Use array_at_struct_end_p to determine whether the trailing array
of a structure is flexible array member in __builtin_object_size.
gcc/ChangeLog:
PR tree-optimization/101836
* tree-object-size.cc (addr_object_size): Use array_at_struct_end_p
to determine a flexible array
Add the following new option -fstrict-flex-arrays[=n] and a corresponding
attribute strict_flex_arrays to GCC:
'-fstrict-flex-arrays'
Treat the trailing array of a structure as a flexible array member
in a stricter way. The positive form is equivalent to
'-fstrict-flex-arrays=3', w
Instead of defining these in terms of a helper class template
and the relatively expensive __remove_cv_t, just declare four
explicit specializations of the main template, one for each choice
of cv-quals.
Tested on x86_64-pc-linux-gnu, does this look OK for trunk?
The is_void change alone reduces m
Instead of defining is_reference in terms of is_lvalue_reference
and is_rvalue_reference, just define it directly.

This reduces memory usage of join.cc by 1%.

I added c_expr::m_decimal in r13-2386-gbedfca647a9e9c1a as part of the
implementation of -Wxor-used-as-pow, but I missed various places where
the field needed to be initialized.
Fixed thusly (based on searching for places that assign to
the original_code field).

Ok, following patch introduces
This libgo patch ignores the __morestack function in runtime.Callers.
We were ignoring all functions starting with "__morestack_", but not
the function "__morestack" itself. Without this change, some tests
such as recover.go started failing recently, though I'm not sure
exactly what changed. Boot
An email discussion of optimizing EH led me to wonder why we weren't doing
this already. Not that this change affects EH at all.
Tested x86_64-pc-linux-gnu. Does this seem worthwhile?
