2020-10-25Correct decls for functions which do not pass actual arguments.Thomas Koenig1-4/+21
A wrong decl for findloc caused segfaults at runtime on Darwin for ARM; however, this is only a symptom of a larger disease: The declarations for our library functions are often inconsistent. This patch solves that problem for the functions specifically for the functions for which we do not pass optional arguments, i.e. findloc and (min|max)loc. It works by saving the symbols of the specific functions in gfc_intrinsic_namespace and by generating the formal argument lists from the actual argument lists. Because symbols are re-used, so are the backend decls. gcc/fortran/ChangeLog: PR fortran/97454 * gfortran.h (gfc_symbol): Add pass_as_value flag.

2020-07-05Test global identifiers against what is specified interfaces.Thomas Koenig1-1/+7
Apart from calling gfc_compare_interfaces to check interfaces against global identifiers, this also sets and check a few sym->error flags to avoid duplicate error messages. I thought about issuing errors on mismatched interfaces, but when the procedure is not invoked, a warning should be enough to alert the user. gcc/fortran/ChangeLog: PR fortran/27318 * frontend-passes.c (check_against_globals): New function.

2020-06-14When avoiding double deallocation, look at namespace, expression and component.Thomas Koenig1-0/+12
Our finalization handling is a mess. Really, we should get to try and get this fixed for gcc 11. In the meantime, here is a patch which fixes a regression I introduced when fixing a regression with a memory leak. The important thing here is to realize that we do not need to finalize (and deallocate) multiple times for the same expression and the same component in the same namespace. It might cause code size regressions, but better big code than wrong code... gcc/fortran/ChangeLog: PR fortran/94109 * class.c (finalize_component): Return early if finalization has already happened for expression and component within namespace. * gfortran.h (gfc_was_finalized): New type.

2020-05-20Fortran : ProcPtr function results: 'ppr@' in error message PR39695Mark Eggleston1-2/+5
The value 'ppr@' is set in the name of result symbol, the actual name of the symbol is in the procedure name symbol pointed to by the result symbol's namespace (ns). When reporting errors for symbols that have the proc_pointer attribute check whether the result attribute is set and set the name accordingly. 2020-05-20 Mark Eggleston <markeggleston@gcc.gnu.org> gcc/fortran/ PR fortran/39695 * resolve.c (resolve_fl_procedure): Set name depending on whether the result attribute is set.

2018-01-05PR 78534 Change character length from int to size_tJanne Blomqvist1-1/+1
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. frontend: 2018-01-05 Janne Blomqvist <jb@gcc.gnu.org> PR fortran/78534 PR fortran/66310 * array.c (got_charlen): Use gfc_charlen_int_kind. * class.c (gfc_find_derived_vtab): Use gfc_size_kind instead of hardcoded kind.
