2025-06-18Fortran: various fixes for STAT/LSTAT/FSTAT intrinsics [PR82480]Harald Anlauf1-124/+150
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.

2025-06-11libfortran: Simplify Makefile logicFrancois-Xavier Coudert3-1245/+967
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 2025-06-10 François-Xavier Coudert <fxcoudert@gcc.gnu.org> libgfortran/ChangeLog: PR libfortran/116400 * Makefile.am: Simplify logic. * Makefile.in: Regenerate. * regenerate.sh: Add some checks.

2025-05-13libfortran: Fix up _gfortran_{,m,s}findloc2_s{1,4} [PR120196]Jakub Jelinek3-6/+6
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. 2025-05-13 Jakub Jelinek <jakub@redhat.com> PR libfortran/120196 * m4/ifindloc2.m4 (header1, header2): For back use i > 0 rather than i >= 0 as for condition. * generated/findloc2_s1.c: Regenerate. * generated/findloc2_s4.c: Regenerate. * gfortran.dg/pr120196.f90: New test.
2025-05-13libfortran: Fix up _gfortran_s{max,min}loc1_{4,8,16}_s{1,4} [PR120191]Jakub Jelinek13-39/+26
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. 2025-05-13 Jakub Jelinek <jakub@redhat.com> PR fortran/120191 * m4/ifunction-s.m4 (SCALAR_ARRAY_FUNCTION): Don't multiply GFC_DESCRIPTOR_EXTENT(array,) by string_len. * generated/maxloc1_4_s1.c: Regenerate. * generated/maxloc1_4_s4.c: Regenerate. * generated/maxloc1_8_s1.c: Regenerate. * generated/maxloc1_8_s4.c: Regenerate. * generated/maxloc1_16_s1.c: Regenerate. * generated/maxloc1_16_s4.c: Regenerate. * generated/minloc1_4_s1.c: Regenerate. * generated/minloc1_4_s4.c: Regenerate. * generated/minloc1_8_s1.c: Regenerate. * generated/minloc1_8_s4.c: Regenerate. * generated/minloc1_16_s1.c: Regenerate. * generated/minloc1_16_s4.c: Regenerate. * gfortran.dg/pr120191_3.f90: New test.
2025-05-13libfortran: Fix up _gfortran_s{max,min}loc2_{4,8,16}_s{1,4} [PR120191]Jakub Jelinek14-28/+28
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.). 2025-05-13 Jakub Jelinek <jakub@redhat.com> PR fortran/120191 * m4/maxloc2s.m4: For smaxloc2 call maxloc2 if mask is NULL or *mask.

2025-05-08libfortran: Fix up maxval/maxloc for UNSIGNED [PR120158]Jakub Jelinek36-91/+91
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*. 2025-05-07 Jakub Jelinek <jakub@redhat.com> PR libfortran/120158 * m4/iparm.m4 (atype_min): For atype_name starting with GFC_UINTEGER define to 0. * generated/maxloc0_16_m1.c: Regenerate. * generated/maxloc0_16_m2.c: Regenerate. * generated/maxloc0_16_m4.c: Regenerate. * generated/maxloc0_16_m8.c: Regenerate. * generated/maxloc0_16_m16.c: Regenerate. * generated/maxloc0_4_m1.c: Regenerate. * generated/maxloc0_4_m2.c: Regenerate. * generated/maxloc0_4_m4.c: Regenerate. * generated/maxloc0_4_m8.c: Regenerate. * generated/maxloc0_4_m16.c: Regenerate. * generated/maxloc0_8_m1.c: Regenerate. * generated/maxloc0_8_m2.c: Regenerate. * generated/maxloc0_8_m4.c: Regenerate. * generated/maxloc0_8_m8.c: Regenerate. * generated/maxloc0_8_m16.c: Regenerate. * generated/maxloc1_16_m1.c: Regenerate. * generated/maxloc1_16_m2.c: Regenerate. * generated/maxloc1_16_m4.c: Regenerate. * generated/maxloc1_16_m8.c: Regenerate. * generated/maxloc1_16_m16.c: Regenerate. * generated/maxloc1_4_m1.c: Regenerate. * generated/maxloc1_4_m2.c: Regenerate. * generated/maxloc1_4_m4.c: Regenerate. * generated/maxloc1_4_m8.c: Regenerate. * generated/maxloc1_4_m16.c: Regenerate. * generated/maxloc1_8_m1.c: Regenerate. * generated/maxloc1_8_m2.c: Regenerate. * generated/maxloc1_8_m4.c: Regenerate. * generated/maxloc1_8_m8.c: Regenerate. * generated/maxloc1_8_m16.c: Regenerate. * generated/maxval_m1.c: Regenerate. * generated/maxval_m2.c: Regenerate. * generated/maxval_m4.c: Regenerate. * generated/maxval_m8.c: Regenerate. * generated/maxval_m16.c: Regenerate.

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. 2025-05-07 Jakub Jelinek <jakub@redhat.com> PR libfortran/120153 * Makefile.am (i_maxloc1_c): Add generated/maxloc1_16_m16.c. * intrinsics/random.c (arandom_m16): Use #ifdef HAVE_GFC_UINTEGER_16 guard rather than #ifdef GFC_HAVE_GFC_UINTEGER_16. * gfortran.map (GFORTRAN_15): Remove _gfortran_arandom_m16, _gfortran_maxloc1_16_m16, _gfortran_mmaxloc1_16_m16 and _gfortran_smaxloc1_16_m16.

2025-02-20Fortran: Move caf_get-rewrite to coarray.cc [PR107635]Andre Vehreschild2-9/+8
Add a rewriter to keep all expression tree that is not optimization together. At the moment this is just a move from resolve.cc, but will be extended to handle more cases where rewriting the expression tree may be easier. The first use case is to extract accessors for coarray remote image data access. gcc/fortran/ChangeLog: PR fortran/107635 * Make-lang.in: Add coarray.cc. * coarray.cc: New file. * gfortran.h (gfc_coarray_rewrite): New procedure. * parse.cc (rewrite_expr_tree): Add entrypoint for rewriting expression trees. * resolve.cc (gfc_resolve_ref): Remove caf_lhs handling.
