Fix non-standard behaviour of std::istream_iterator

The current implementation of istream_iterator allows the iterator to be
reused after reaching end-of-stream, so that subsequent reads from the
stream can succeed (e.g. if the stream state has been cleared and stream
position changed from EOF). The P0738R2 paper clarified that the
expected behaviour is to set the stream pointer to null after reaching
end-of-stream, preventing further reads.

This implements that requirement, and adds the new default constructor
to std::ostream_iterator.

* include/bits/stream_iterator.h (istream_iterator::_M_equal()): Make
private.

Simplify setjmp and non-local goto implementation (PR84521)

This fixes and simplifies the setjmp and non-local goto implementation.
Currently the virtual frame pointer is saved when using __builtin_setjmp or
a non-local goto.  Depending on whether a frame pointer is used, this may
either save SP or FP with an immediate offset.  However the goto or longjmp
always updates the hard frame pointer.

A receiver veneer in the original function then assigns the hard frame pointer
to the virtual frame pointer, which should, if it works correctly, again assign
SP or FP.  However the special elimination code in eliminate_regs_in_insn
doesn't do this correctly unless the frame pointer is used, and even if it
worked by writing SP, the frame pointer would still be corrupted.

A much simpler implementation is to always save and restore the hard frame
pointer.  This avoids 2 redundant instructions which add/subtract the virtual
frame offset.  A large amount of code can be removed as a result, including all
implementations of TARGET_BUILTIN_SETJMP_FRAME_VALUE (all of which already use
the hard frame pointer).  The expansion of nonlocal_goto on PA can be simplied
to just restore the hard frame pointer.

This fixes the most obvious issues, however there are still issues on targets
which define HARD_FRAME_POINTER_IS_FRAME_POINTER (arm, mips).
Each function could have a different hard frame pointer, so a non-local goto
may restore the wrong frame pointer (TARGET_BUILTIN_SETJMP_FRAME_VALUE could
be useful for this).

The i386 TARGET_BUILTIN_SETJMP_FRAME_VALUE was incorrect: if stack_realign_fp
is true, it would save the hard frame pointer value but restore the virtual
frame pointer which according to ix86_initial_elimination_offset can have a
non-zero offset from the hard frame pointer.

The ia64 implementation of nonlocal_goto seems incorrect since the helper
function moves the the frame pointer value into the static chain register
(so this patch does nothing to make it better or worse).

AArch64 + x86-64 bootstrap OK, new test passes on AArch64, x86-64 and Arm.

rsandifo [Tue, 18 Jun 2019 14:54:34 +0000 (14:54 +0000)]
[AArch64] Add a new CC mode for SVE conditions

The SVE ACLE patches need to introduce a new CC_NZC mode for the
conditions that can be tested after a PTRUE.  In particular, LT needs
to map to "mi"/"first" and GE to "pl"/"nfrst", instead of the normal
CC mapping.

Another advantage of using a separate mode is that we can print the SVE
names of the conditions, which makes the output a bit easier to read.
It therefore seems like an independent improvement that can go in now.

The patch also avoids using (compare X (const_int 0)), because that gets
folded away when used with LTU and GEU ("cc"/"last" and "cs"/"nlast").
Just using an unspec should be OK.

The full set of conditions can't be tested without other SVE ACLE patches.

PR libstdc++/90281 Fix string conversions for filesystem::path

Fix several bugs in the encoding conversions for filesystem::path that
prevent conversion of Unicode characters outside the Basic Multilingual
Plane, and prevent returning basic_string specializations with
alternative allocator types.

The std::codecvt_utf8 class template is not suitable for UTF-16
conversions because it uses UCS-2 instead. For conversions between UTF-8
and UTF-16 either std::codecvt<C, char, mbstate> or
codecvt_utf8_utf16<C> must be used.

The __str_codecvt_in and __str_codecvt_out utilities do not
return false on a partial conversion (e.g. for invalid or incomplete
Unicode input). Add new helpers that treat partial conversions as
errors, and use them for all filesystem::path conversions.

3 days ago[Darwin] The need for picsym stubs is dependent on linker used, not OS rev.
iains [Sun, 16 Jun 2019 16:21:28 +0000 (16:21 +0000)]
[Darwin] The need for picsym stubs is dependent on linker used, not OS rev.

For very old toolchains, the compiler generated pic symbol stubs that
provide the necessary indirections.  We no longer need this (since xcode
3 era) and it's more efficient for the linker to make one stub when it
knows a symbol is needed that for us to emit them speculatively in every
object.

Our current codegen is making the assumption that a specific OS version
uses a specific linker version - and therefore the presence of support
could be based on the target OS rev.  Of course, that's way too simplistic
(most likely bogus for cross-toolchains) and we want to make things explict.

Since we have detection of the linker version, we can use that directly
(A config test for support for stub-less linking might also be feasible
but much more involved).

Finally, should the user wish to generate code that caters for export to
use in an environment with an older toolchain, the generation of stubs
can be forced from the command line.

In addition to the points above, branch islanding and a long branch opt
for PowerPC Darwin has become conflated with the emission of these stubs
(which is confusing, and will be rectified in a following patch).
