This new implementation has a smaller footprint than the previous

type that only needs a single pointer. The _M_type enumeration is also
combined with the pimpl type, by using a tagged pointer, reducing

[libgomp, nvptx] Fix libgomp.c/target-5.c compilation

Libgomp test-case libgomp.c/target-5.c is failing to compile when building for
x86_64 with nvptx accelerator due to missing:
- getpid
- gethostname
- isatty (pulled in by fwrite)
in the nvptx newlib.

This patch fixes the build failure by:
- adding a function gomp_print_string which limits the use of fwrite to a single
  location (in affinity-fmt.c), and
- creating an nvptx version of affinity-fmt.c, which:
  - overrides the configure test results HAVE_GETPID and HAVE_GETHOSTNAME, and
  - implements fwrite using write.

Build and reg-tested on x86_64 with nvptx accelerator.

[AArch64][doc] Clarify -msve-vector-bits=128 behaviour

We've received reports about the -msve-vector-bits=128 bits being somewhat ambiguous.
It isn't clear whether -msve-vector-bits=128 forces vector-length-agnostic code or whether
-msve-vector-bits=scalable forces 128-bit vector-lengh-specific code.
The latter is a, perhaps unintuitive, reading that we want to exclude.

This patch makes it more explicit that -msve-vector-bits=128 is special and produces
vector-length *agnostic* code. In the end, I've rewritten the whole option documentation.

Checked make pdf that the output looks reasonable.

Richard Earnshaw [Tue, 11 Dec 2018 11:26:15 +0000 (11:26 +0000)]
[aarch64] PR target/87369 Prefer bsl/bit/bif for copysign

The copysign operations will almost always be performed on values in
floating-point registers.  As such, we do not want the compiler to
simplify the operations into code sequences that can only be done
using the general-purpose register set.  Unfortunately, this is what
is currently happening.

Fortunately, it seems quite unlikely that copysign() will be
subsequently followed by other logical operations on the values
involved, so I think it is acceptable to use an unspec here.  This
allows us to preserve the operation in a form that allows the register
allocator to make the right choice later on, without limitation on the
final form of the operation (well, if we do end up using the gp
register bank, we get a dead constant load that we cannot easily
eliminate at a late stage).
