Maciej W. Rozycki 963d6c79ea RISC-V: Fix floating-point environment support for soft float
We don't have floating-point exception or non-default rounding mode
support for the RISC-V soft-float environment, `feraiseexcept' and
`fesetround' do nothing unless the `__riscv_flen' macro has been set.
Therefore following ISO C language requirements[1] only define macros
for soft float that correspond to actually supported floating-point
environment features, removing failures from GCC testing such as:

FAIL: gcc.dg/torture/fp-int-convert-timode-3.c   -O0  execution test
FAIL: gcc.dg/torture/fp-int-convert-timode-4.c   -O0  execution test

Thomas Schwinge 654072d7a2 nvptx: Remove newlib ELIX level 1 restriction
Such a hard-coded ELIX level restriction is only being applied for nvptx
newlib -- but we'd actually like higher levels' functions available there,
too.  (Users continue to be able to override this via newlib 'configure',
as for every other newlib target.)

This already enables GCC test cases that currently FAIL due to
'unresolved symbol strndup' ('gcc.dg/builtin-dynamic-object-size-0.c'), or
'unresolved symbol mempcpy' ('gcc.dg/torture/pr45636.c'), for example.

The new loop in open_shared has a subtil performance problem.
Next_address is bumped only if mapping at this address
failed.  Every subsequent call to open_shared has a high probability
having to call MapViewOfFileEx twice, because next_address is still
set to the address of the last successful mapping.

Avoid this by bumping next_address every time.

While at it, fix a comment.

Corinna Vinschen 9ddd48ee1b Cygwin: /proc/<PID>/maps: print real shared region addresses
So far, the addresses printed for the shared regions of a process
were faked.  The assumption was that the shared regions are always
in the same place in all processes, so we just printed the addresses
of the current process.  This is no safe bet.  The only safe bet is
the address of the cygheap.  So keep track of the addresses in the
cygheap and read the addresses from the cygheap of the observed
processes.  Add output for the shared console.
