8e2c6e7b42 libfortran: Fix execute_command_line for Windows
On Windows, 'system' is called - that fails with -1 if the command
interpreter could not be started; on POSIX systems, if the child
process could not be started by the shell, exit(127)/_exit(127) is
called/returned. On Windows, cmd.exe (and also the PowerShell) return
errorlevel 9009.

libgfortran/ChangeLog:

	* intrinsics/execute_command_line.c (execute_command_line): On
	Windows, regard system()'s return value of 9009 as EXEC_INVALIDCOMMAND.

902c755930 Always define WIN32_LEAN_AND_MEAN before <windows.h>
Recently, mingw-w64 has got updated <msxml.h> from Wine which is included
indirectly by <windows.h> if `WIN32_LEAN_AND_MEAN` is not defined. The
`IXMLDOMDocument` class has a member function named `abort()`, which gets
affected by our `abort()` macro in "system.h".

`WIN32_LEAN_AND_MEAN` should, nevertheless, always be defined. This
can exclude 'APIs such as Cryptography, DDE, RPC, Shell, and Windows
Sockets' [1], and speed up compilation of these files a bit.

133d0d422e fortran, libgfortran: Avoid using libquadmath for glibc 2.26+
As mentioned by Joseph in PR105101, glibc 2.26 or later has on x86
(both -m32/-m64), powerpc64le, ia64 and mips support for
*f128 math/complex APIs plus strtof128 and strfromf128, and these APIs allow
us to avoid libquadmath for Fortran purposes on these architectures,
replace *q math/complex APIs, strtof128 instead of strtoflt128 and,
while strfromf128 unfortunately isn't a perfect replacement to
quadmath_snprintf, it can be made to work.

The advantage of this is that when configured against such glibcs
(2.26 is now almost 5 years old), we can avoid linking against an extra shared
library and the math support in glibc is maintained better than libquadmath.

We need both a compiler change (so that for glibc 2.26+ it uses *f128 APIs
instead of *q) and library change.

The above mentioned problem with strfromf128 is that the strfrom* functions
are severely restricted versions of snprintf.  In libgfortran, we handle
!isfinite differently and just use snprintf/quadmath_snprintf for
%+-#.*{L,Q}{f,e} printing.
strfrom* doesn't allow +, -, # modifiers and it only supports .34 or
similar precision, not .* .  The L/Q etc. letters are omitted.
The + is there to force + sign at the start if it is positive.
Workaround in the patch is to add the + at the start manually for
!signbit (val).
The - (left alignment instead of right) I don't understand why we need it,
when minimum field width isn't specified (for strfrom* can't be specified),
no padding is ever added anywhere I believe.
The # is to force adding . - workaround is to search for first . or e or '\0'
character, if it is '\0', just append ., if it is e, insert . before e and
memmove the rest (which is just a few bytes, e, +/- and at most a few digits)
one byte later.
The .* case is handled by creating the format string for strfrom* by
snprintf into a temporary buffer.

As requested, this patch also switches from using __float128 type in
libgfortran to _Float128 which is equivalent on all arches that support
__float128.

The change is done in a backwards compatible change, when GCC is configured
against glibc 2.26 or newer, libgfortran.so.5 itself doesn't link against
-lquadmath nor uses any libquadmath APIs, libgfortran.a doesn't use any
libquadmath APIs either.  User programs and libraries when being linked
by gfortran driver are linked against -lgfortran and -lquadmath, but
the latter only in the --as-needed linker mode, which means it needs
to be around during linking and will be linked in if there are any
calls to math/complex functions with real(kind=16) or complex(kind=16)
in compilation units compiled by older versions of gcc, but if either
user code doesn't call those math/complex functions for the largest
supported kind, or the code is recompiled by gcc with this change in,
libquadmath won't be linked in.

00f6de9c69 Fortran: Fix assumed-size to assumed-rank passing [PR94070]
This code inlines the size0 and size1 libgfortran calls, the former is still
used by libgfortan itself (and by old code). Besides permitting more
optimizations, it also permits to handle assumed-rank dummies better: If the
dummy argument is a nonpointer/nonallocatable, an assumed-size actual arg is
repesented by having ubound == -1 for the last dimension. However, for
allocatable/pointers, this value can also exist. Hence, the dummy arg attr
has to be honored.

For that reason, when calling an assumed-rank procedure with nonpointer,
nonallocatable dummy arguments, the bounds have to be updated to avoid
the case ubound == -1 for the last dimension.

Runtime error occurs when the type of the value argument is

The status argument, intent(out), will contain -1 if the value
of the environment is too large to fit in the value argument, this
is the case if the type is character(0) so there is no reason to

The following patch provides some further math library fallbacks.
fmaf can be implemented using fma if available, fma and fmal can use
x * y + z as fallback, it is not perfect, but e.g. glibc on various arches
has been using that as fallback for many years,
and copysign/copysignl/fabs/fabsl can be implemented using corresponding
__builtin_* if we make sure that gcc expands it inline instead of using
a library call (these days it is expanded inline on most targets).

0eaee4abb1 Improve PRNG jumping when using threads
Currently, when a new thread needs to use the RANDOM_NUMBER intrinsic,
the per-thread PRNG state is initialized by copying the master state
and then jumping forwards N*2**128 entries in the stream so that the
PRNG streams for different threads don't alias each other, where N is
the number of threads that have so far initialized the PRNG.

With this patch the master state itself is jumped forwards once each
time a new thread initializes the PRNG, thus obviating the need to
jump through all the N-1 previous streams. Effectively turning an O(N)
algorithm into an O(1) one.

d66d6d15f1 Use getentropy() for seeding PRNG
The getentropy function, found on Linux, OpenBSD, and recently also
FreeBSD, can be used to get random bytes to initialize the PRNG.  It
is similar to the traditional way of reading from /dev/urandom, but
being a system call rather than a special file, it doesn't suffer from
problems like running out of file descriptors, or failure when running
in a container where /dev/urandom may not be available.

Regtested on x86_64-pc-linux-gnu, Ok for trunk?

7a15726687 Use pointer sized array indices.
Using pointer sized variables (e.g. size_t / ptrdiff_t) when the
variables are used as array indices allows accessing larger arrays,
and can be a slight performance improvement due to no need for sign or
zero extending, or masking.

Regtested on x86_64-pc-linux-gnu.

f622221ab4 PR 78534 Change character length from int to size_t
In order to handle large character lengths on (L)LP64 targets, switch
the GFortran character length from an int to a size_t.

This is an ABI change, as procedures with character arguments take
hidden arguments with the character length.

I also changed the _size member in vtables from int to size_t, as
there were some cases where character lengths and sizes were
apparently mixed up and caused regressions otherwise. Although I
haven't tested, this might enable very large derived types as well.

Also, as there are some places in the frontend were negative character
lengths are used as special flag values, in the frontend the character
length is handled as a signed variable of the same size as a size_t,
although in the runtime library it really is size_t.

I haven't changed the character length variables for the co-array
intrinsics, as this is something that may need to be synchronized with
OpenCoarrays.

This is v5 of the patch. v4 was applied but caused breakage on big
endian targets. These have been fixed and tested, thanks to access to
the GCC compile farm.

Overview of v4 of the patch: v3 was applied but had to reverted due to
breaking bootstrap. The fix is in resolve.c:resolve_charlen, where
it's necessary to check that an expression is constant before using
mpz_sgn.

Overview of v3 of the patch: All the issues pointed out by FX's review
of v2 have been fixed. In particular, there are now new functions
gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions
mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT
instead of a long value. Similarly, gfc_get_int_expr now takes a
HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by
gfc_extract_hwi. Also, the preliminary work to handle
gfc_charlen_type_node being unsigned has been removed.

Regtested on x86_64-pc-linux-gnu, i686-pc-linux-gnu and
powerpc64-unknown-linux-gnu. Also regtested all three targets by
modifying gfortran-dg.exp to also test with "-g -flto", no new
failures observed.
