Thomas Schwinge 3b58032de1 nvptx: Don't use global constructor for SSP setup
Given that nvptx newlib currently restricts itself to ELIX level 1, this
is not already a problem.  However, in the following we'd like to lift
that restriction, and then run into:

    [...]/newlib/libc/ssp/stack_protector.c: In function ‘__stack_chk_init’:
    [...]/newlib/libc/ssp/stack_protector.c:31:1: sorry, unimplemented: global constructors not supported on this target
       31 | }
          | ^

GCC patch "nvptx: Support global constructors/destructors via 'collect2'"
has been posted, but not yet accepted.  Until that is resolved, use the
same manual SSP setup as for GCN.

Corinna Vinschen 7e332208a0 Cygwin: open_shared: always bump next_address
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.

Kwok Cheung Yeung e18743072b amdgcn: Add vectorized math routines
This implements a set of vectorized math routines to be used by the
compiler auto-vectorizer.  Versions for vectors with 2 lanes up to
64 lanes (in powers of 2) are provided.

These routines are based on the scalar versions of the math routines in
libm/common, libm/math and libm/mathfp.  They make extensive use of the GCC
C vector extensions and GCN-specific builtins in GCC.

Corinna Vinschen 31302b267b Cygwin: drop fixed addresses for standard shared regions
With the previous commit 9ddd48ee1b ("Cygwin: /proc/<PID>/maps:
print real shared region addresses"), the real addresses of
the standard shared regions (cygwin, user, myself, shared console)
are read from the printed process itself.  We don't need fixed
addresses anymore, so drop the definitions and simplify open_shared.

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.

For non-fixed regions, try to allocate in a loop within the area

Linux always prints topology info if the kernel has been built with

Cygwin: CI: Run cygserver for tests
Note that cygserver must be run using the same cygwin1.DLL as test
programs, as they communicate over a named pipe whose name contains the
'installation key' (which is a hash of the cygwin1.dll's path).

We run cygserver via 'cmd' to avoid the special code which handles a
cygwin parent process starting a cygwin child process, which assumes the
same version of cygwin in both.

Cygwin: testsuite: Build testcases using automake
Build all the testcase executables directly using automake, rather than
passing the compiler information into DejaGnu to have it build them.

(This means you get build avoidance for these executables, so they only
get built once, rather than every time you run the test, and makes it
much easier to run them in isolatation against the installed Cygwin,
which is really nice to have when trying to fix broken tests...)

Rename the 'cygrun' subdirectory to 'mingw', and build all the testsuite
MinGW executables there.

Drop sample-miscompile.c (testing that compile failure is detected is
perhaps useful, but not here...)
