2024-03-20Use integer_{zero,one}_node some moreJakub Jelinek6-14/+14
When looking at the analyzer MEM_REF invalid second arg issue, I've noticed tons of build_int_cst (integer_type_node, {0,1}) or build_zero_cst (integer_type_node) cases.

When an exception is encountered during simplification of arithmetic expressions, the result may depend on whether range-checking is active (-frange-check) or not. However, the code path in the front-end should stay the same for "soft" errors for which the exception is triggered by the check, while "hard" errors should always terminate the simplification, so that error recovery is independent of the flag.

2024-02-28Fortran - Error compiling PDT Type-bound Procedures [PR82943/86148/86268]Alexander Westbrooks4-9/+108
This patch allows parameterized derived types to compile successfully when typebound procedures are specified in the type specification. Furthermore, it allows function calls for PDTs by setting the f2k_derived space of PDT instances to reference their original template, thereby giving it referential access to the typebound procedures of the template. Lastly, it adds a check for deferred length parameters of PDTs in CLASS declaration statements, and correctly throws an error if such declarations are missing POINTER or ALLOCATABLE attributes. 2024-02-25 Alexander Westbrooks <alexanderw@gcc.gnu.org> gcc/fortran/ChangeLog: PR fortran/82943 PR fortran/86148 PR fortran/86268 * decl.cc (gfc_get_pdt_instance): Set the PDT instance field 'f2k_derived', if not set already, to point to the given PDT template 'f2k_derived' namespace in order to give the PDT instance referential access to the typebound procedures of the template. * gfortran.h (gfc_pdt_is_instance_of): Add prototype. * resolve.cc (resolve_typebound_procedure): If the derived type does not have the attribute 'pdt_template' set, compare the dummy argument to the 'resolve_bindings_derived' type like usual.

2024-02-17fortran: gfc_trans_subcomponent_assign fixes [PR113503]Jakub Jelinek1-10/+8
The r14-870 changes broke xtb package tests (reduced testcase is the first one below) and caused ICEs on a test derived from that (the second one). For the x = T(u = trim (us(1))) statement, before that change gfortran used to emit weird code with 2 trim calls: _gfortran_string_trim (&len.2, (void * *) &pstr.1, 20, &us[0]); if (len.2 > 0) { __builtin_free ((void *) pstr.1); } D.4275 = len.2; t.0.u = (character(kind=1)[1:0] *) __builtin_malloc (MAX_EXPR <(sizetype) D.4275, 1>); t.0._u_length = D.4275; _gfortran_string_trim (&len.4, (void * *) &pstr.3, 20, &us[0]); (void) __builtin_memcpy ((void *) t.0.u, (void *) pstr.3, (unsigned long) NON_LVALUE_EXPR <len.4>); if (len.4 > 0) { __builtin_free ((void *) pstr.3); } That worked at runtime, though it is wasteful. That commit changed it to: slen.3 = len.2; t.0.u = (character(kind=1)[1:0] *) __builtin_malloc (MAX_EXPR <(sizetype) slen.3, 1>); t.0._u_length = slen.3; _gfortran_string_trim (&len.2, (void * *) &pstr.1, 20, &us[0]); (void) __builtin_memcpy ((void *) t.0.u, (void *) pstr.1, (unsigned long) NON_LVALUE_EXPR <len.2>); if (len.2 > 0) { __builtin_free ((void *) pstr.1); } which results in -Wuninitialized warning later on and if one is unlucky and the uninitialized len.2 variable is smaller than the trimmed length, it results in heap overflow and often crashes later on. The bug above is clear, len.2 is only initialized in the _gfortran_string_trim (&len.2, (void * *) &pstr.1, 20, &us[0]); call, but used before that. Now, the slen.3 = len.2; t.0.u = (character(kind=1)[1:0] *) __builtin_malloc (MAX_EXPR <(sizetype) slen.3, 1>); t.0._u_length = slen.3; statements come from the alloc_scalar_allocatable_subcomponent call, while _gfortran_string_trim (&len.2, (void * *) &pstr.1, 20, &us[0]); from the gfc_conv_expr (&se, expr); call which is done before the alloc_scalar_allocatable_subcomponent call, but is only appended later on with gfc_add_block_to_block (&block, &se.pre); Now, obviously the alloc_scalar_allocatable_subcomponent emitted statements can depend on the se.pre sequence statements which can compute variables used by alloc_scalar_allocatable_subcomponent like the length. On the other side, I think the se.pre sequence really shouldn't depend on the changes done by alloc_scalar_allocatable_subcomponent, that is initializing the FIELD_DECLs of the destination allocatable subcomponent only, the gfc_conv_expr statements are already created, so all they could in theory depend above is on t.0.u or t.0._u_length, but I believe if the rhs dependened on the lhs content (which is allocated by those statements but really uninitialized), it would need to be discovered by the dependency analysis and forced into a temporary. So, in order to fix the first testcase, the second hunk of the patch just emits the se.pre block before the alloc_scalar_allocatable_subcomponent changes rather than after it. The second problem is an ICE on the second testcase. expr in the caller (expr2 inside of alloc_scalar_allocatable_subcomponent) has expr2->ts.u.cl->backend_decl already set, INTEGER_CST 20, but alloc_scalar_allocatable_subcomponent overwrites it to a new VAR_DECL which it assigns a value to before the malloc. That can work if the only places the expr2->ts is ever used are in the same local block or its subblocks (and only if it is dominated by the code emitted by alloc_scalar_allocatable_subcomponent, so e.g. not if that call is inside of a conditional code and use later unconditional), but doesn't work if expr2->ts is used before that block or after it. So, the exact ICE is because of: slen.1 = 20; static character(kind=1) us[1][1:20] = {"foo "}; x.u = 0B; x._u_length = 0; { struct t t.0; struct t D.4308; { integer(kind=8) slen.1; slen.1 = 20; t.0.u = (character(kind=1)[1:0] *) __builtin_malloc (MAX_EXPR <(sizetype) slen.1, 1>); t.0._u_length = slen.1; (void) __builtin_memcpy ((void *) t.0.u, (void *) &us[0], 20); } where the first slen.1 = 20; is emitted because it sees us has a VAR_DECL ts.u.cl->backend_decl and so it wants to initialize it to the actual length. This is invalid GENERIC, because the slen.1 variable is only declared inside of a {} later on and so uses outside of it are wrong. Similarly wrong would be if it is used later on. E.g. in the same testcase if it has type(T) :: x, y x = T(u = us(1)) y%u = us(1) then there is { integer(kind=8) slen.1; slen.1 = 20; t.0.u = (character(kind=1)[1:0] *) __builtin_malloc (MAX_EXPR <(sizetype) slen.1, 1>); t.0._u_length = slen.1; (void) __builtin_memcpy ((void *) t.0.u, (void *) &us[0], 20); } ... if (y.u != 0B) goto L.1; y.u = (character(kind=1)[1:0] *) __builtin_malloc (MAX_EXPR <(sizetype) slen.1, 1>); i.e. another use of slen.1, this time after slen.1 got out of scope. I really don't understand why the code modifies expr2->ts.u.cl->backend_decl, expr2 isn't used there anywhere except for expr2->ts.u.cl->backend_decl expressions, so hacks like save the previous value, overwrite it temporarily over some call that will use expr2 and restore afterwards aren't needed - there are no such calls, so the following patch fixes it just by not messing up with expr2->ts.u.cl->backend_decl, only set it to size variable and overwrite that with a temporary if needed. 2024-02-17 Jakub Jelinek <jakub@redhat.com> PR fortran/113503 * trans-expr.cc (alloc_scalar_allocatable_subcomponent): Don't overwrite expr2->ts.u.cl->backend_decl, instead set size to expr2->ts.u.cl->backend_decl first and use size instead of expr2->ts.u.cl->backend_decl.

2024-02-14pretty-print: Fix up ptrdiff handling for %tu, %to, %txJakub Jelinek1-7/+8
This is IMHO more of a theoretical case, I believe my current code doesn't handle %tu or %to or %tx correctly if ptrdiff_t is not one of int, long int or long long int. For size_t and %zd or %zi I'm using va_arg (whatever, ssize_t) and hope that ssize_t is the signed type corresponding to size_t which C99 talks about. For ptrdiff_t there is no type for unsigned type corresponding to ptrdiff_t and I'm not aware of a portable way on the host to get such a type (the fmt tests use hacks like #define signed /* Type might or might not have explicit 'signed'. */ typedef unsigned __PTRDIFF_TYPE__ unsigned_ptrdiff_t; #undef signed but that only works with compilers which predefine __PTRDIFF_TYPE__), std::make_unsigned<ptrdiff_t> I believe only works reliably if ptrdiff_t is one of char, signed char, short, int, long or long long, but won't work e.g. for __int20__ or whatever other weird ptrdiff_t the host might have. The following patch assumes host is two's complement (I think we rely on it pretty much everywhere anyway) and prints unsigned type corresponding to ptrdiff_t as unsigned long long printing of ptrdiff_t value masked with 2ULL * PTRDIFF_MAX + 1. So the only actual limitation is that it doesn't support ptrdiff_t wider than long long int. 2024-02-14 Jakub Jelinek <jakub@redhat.com> * pretty-print.cc (PTRDIFF_MAX): Define if not yet defined. (pp_integer_with_precision): For unsigned ptrdiff_t printing with u, o or x print ptrdiff_t argument converted to unsigned long long and masked with 2ULL * PTRDIFF_MAX + 1. * error.cc (error_print): For u printing of ptrdiff_t, print ptrdiff_t argument converted to unsigned long long and masked with 2ULL * PTRDIFF_MAX + 1.

2024-02-13OpenMP: Reject non-const 'condition' trait in FortranTobias Burnus2-6/+27
OpenMP 5.0 only permits constant expressions for the 'condition' trait in context selectors; this is relaxed in 5.2 but not implemented. In order to avoid wrong code, it is now rejected. Additionally, in Fortran, 'condition' should not accept an integer expression, which is now ensured. Additionally, as 'device_num' should be a conforming device number, there is now a check on the value.

I went through suspicios %l in format strings of *printf family functions combined with casts to (long) or (unsigned long) and tried to find out the types of the original expressions that were cast. Quite a few had size_t type, so I've used the new HOST_SIZE_T_PRINT_* macros together with cast to fmt_size_t for those, and then there were quite a few HOST_WIDE_INTs cast to long, used HOST_WIDE_INT_PRINT_* for those without casts.
