The GNU intrinsics STAT/LSTAT/FSTAT were inherited from g77, but changed
the names of some keywords: FILE became NAME, and SARRAY became VALUES,
which are the keywords documented in the gfortran manual.
Adjust code and libgfortran error messages to reflect this change.
Furthermore, add compile-time checking that INTENT(OUT) arguments are
definable, and that array VALUES has at least size 13.
Document that integer arguments are of default kind, and that overflows
in conversion to integer return -1 in VALUES.

Simplify the structure of the Makefile, because now we don't need so
many different variables. Also, list the m4 directory entirely in
EXTRA_DIST instead of individual files, to reduce information
duplication.
I also introduce some level of checking the regenerate.sh script.
It should catch cases where the list of generated files gets out
of sync between Makefile.am and regenerate.sh

As mentioned in the PR, _gfortran_{,m,s}findloc2_s{1,4} iterate too many
times in the back case if nothing is found.
For !back, the loops are for (i = 1; i <= extent; i++) so i is in the
body [1, extent] if nothing is found, but for back it is
for (i = extent; i >= 0; i--) so i is in the body [0, extent] and compares
one element before the start of the array.
Note, findloc1_s{1,4} uses
for (n = len; n > 0; n--, src -= delta * len_array)
for the back loop and
for (n = 1; n <= len; n++, src += delta * len_array)
for !back. This patch fixes that.
The testcase fails under valgrind without the libgfortran changes and
succeeds with those.

There is a bug in _gfortran_s{max,min}loc1_{4,8,16}_s{1,4} which the
following testcase shows.
The functions return but then crash in the caller.
Seems that is because buffer overflows, I believe those functions for
if (mask == NULL || *mask) condition being false are supposed to fill in
the result array with all zeros (or allocate it and fill it with zeros).
My understanding is the result array in that case is integer(kind={4,8,16})
and should have the extents the character input array has.
The problem is that it uses * string_len in the extent multiplication:
extent[n] = GFC_DESCRIPTOR_EXTENT(array,n) * string_len;
and
extent[n] =
GFC_DESCRIPTOR_EXTENT(array,n + 1) * string_len;
which is I guess fine and desirable for the extents of the character array,
but not for the extents of the destination array. Yet the code uses
that extent array for that purpose (and no other purposes).
Here it uses it to set the dimensions for the case where it needs to
allocate (as well as size):
for (n = 0; n < rank; n++)
{
if (n == 0)
str = 1;
else
str = GFC_DESCRIPTOR_STRIDE(retarray,n-1) * extent[n-1];
GFC_DIMENSION_SET(retarray->dim[n], 0, extent[n] - 1, str);
}
Here it uses it for bounds checking of the destination:
if (unlikely (compile_options.bounds_check))
{
for (n=0; n < rank; n++)
{
index_type ret_extent;
ret_extent = GFC_DESCRIPTOR_EXTENT(retarray,n);
if (extent[n] != ret_extent)
runtime_error ("Incorrect extent in return value of"
" MAXLOC intrinsic in dimension %ld:"
" is %ld, should be %ld", (long int) n + 1,
(long int) ret_extent, (long int) extent[n]);
}
}
and here to find out how many retarray elements to actually fill in each
dimension:
while(1)
{
*dest = 0;
count[0]++;
dest += dstride[0];
n = 0;
while (count[n] == extent[n])
{
/* When we get to the end of a dimension, reset it and increment
the next dimension. */
count[n] = 0;
/* We could precalculate these products, but this is a less
frequently used path so probably not worth it. */
dest -= dstride[n] * extent[n];
Seems maxloc1s.m4 and minloc1s.m4 are the only users of ifunction-s.m4,
so we can change SCALAR_ARRAY_FUNCTION in there without breaking anything
else.

I've tried to write a testcase for the BT_CHARACTER maxloc/minloc with named
or unnamed arguments and indeed the just posted patch fixed the arguments
in there in multiple cases to match what the library expects.
But the testcase still fails, due to library problems.
One dealt with in this patch are _gfortran_s{max,min}loc2_{4,8,16}_s{1,4}
functions. Those are trivial wrappers around
_gfortrani_{max,min}loc2_{4,8,16}_s{1,4} which should call those functions
if the scalar mask is true and just return 0 otherwise.
The two bugs I see there is that the back, len arguments are swapped,
which means that it always acts as back=.true. and for len will use
character length of 1 or 0 instead of the desired one.
The _gfortrani_{max,min}loc2_{4,8,16}_s{1,4} functions have prototypes like
GFC_INTEGER_4
maxloc2_4_s1 (gfc_array_s1 * const restrict array, GFC_LOGICAL_4 back, gfc_charlen_type len)
so back comes before len, ditto for the
GFC_INTEGER_4
smaxloc2_4_s1 (gfc_array_s1 * const restrict array,
GFC_LOGICAL_4 *mask, GFC_LOGICAL_4 back, gfc_charlen_type len)
The other problem is that it was just testing if (mask). In my limited
Fortran understanding that means that the optional argument mask was
supplied but nothing about its actual value. Other scalar mask generated
routines use if (mask == NULL || *mask) as the condition when to call the
non-masked function, i.e. when mask is not supplied (then it should act like
.true. mask) or when it is supplied and evaluates to .true.).

When libgfortran is compiled, there are some -Woverflow warnings like
../../../libgfortran/generated/maxloc0_4_m1.c:99:14: warning: unsigned conversion from ‘int’ to ‘GFC_UINTEGER_1’ {aka ‘unsigned char’} changes value from ‘-255’ to ‘1’ [-Woverflow]
99 | maxval = -GFC_UINTEGER_1_HUGE;
| ^
and those actually point a bug in the maxloc*/maxval* implementation
for UNSIGNED.
The intent of
#if defined ('atype_inf`)
result = -atype_inf;
#else
result = atype_min;
#endif
(or similar for maxval) is to initialize the variable with
minimum value of the type, if the type has infinities, then
negative infinity, otherwise the minimum (normalized) value.
atype_min expands for signed integers to say (-GFC_INTEGER_4_HUGE-1)
or for floating point to say -GFC_REAL_8_HUGE.
For UNSIGNED it expands to e.g. -GFC_UINTEGER_4_HUGE, but that is
-0xffffffffU which is 1U, while the minimum value of the type is
0.
Haven't tried to construct testcases for that, but I believe e.g.
maskval could return incorrectly 1 on an array (or masked array)
full of 0s, or maxloc could identify incorrectly the maximum location.
The following patch makes sure atype_min expands to 0 for atype_name
GFC_UINTEGER*.

While looking at PR120152, I have noticed that libgfortran.so doesn't
export 5 *m16* symbols I would have expected that should be exported.
This is caused by 2 issues, one filename was forgotten to be added in r15-4124
to i_maxloc1_c (guess because generated/maxloc1_16_i16.c was kept in the
position after generated/maxloc1_8_m16.c and the i -> m difference wasn't
spotted), and one some garbage prefix on HAVE_GFC_UINTEGER_16 macro.
The first two hunks of this patch fix that.
Though, as GCC 15.1 has been released already, we can't add these symbols
to GFORTRAN_15 symbol version as they've never been there, so the patch
adds them to a new GFORTRAN_15.2 symbol version instead.

The r15-4124-gc0002a675a92e76d change seems to have accidentally
dropped 5 sourcefiles from i_maxloc1_c, which resulted in dropping
15 GFORTRAN_8 symbols on x86_64 and 6 on i686.
The following patch adds it back, so that we export those symbols
again, fixing the ABI problem.

This_image() no longer has a distance formal argument, but a team one.
The source of the distance argument could not be identified, i.e.
whether it came from a TS or standard draft. To implement only the
standard it is removed. Besides being defined, it was not used anyway.

libgfortran and libquadmath [PR119408].
In GCC14, LoongArch added __float128 as an alias for _Float128.
In commit r15-8962, support for q/Q suffixes for 128-bit floating point
numbers. This will cause the compiler to automatically link libquadmath
when compiling Fortran programs. But on LoongArch `long double` is
IEEE quad, so there is no need to implement libquadmath.
This causes link failure.
