fort_dyn_array: add basic fortran dyn array support Fortran provide types whose values may be dynamically allocated or associated with a variable under explicit program control. The purpose of this commit is: * to read allocated/associated DWARF tags and store them in the dynamic property list of main_type. * enable GDB to print the value of a dynamic array in Fortran in case the type is allocated or associated (pointer to dynamic array). Examples: (gdb) p vla_not_allocated $1 = <not allocated> (gdb) p vla_allocated $1 = (1, 2, 3) (gdb) p vla_ptr_not_associated $1 = <not associated> (gdb) p vla_ptr_associated $1 = (1, 2, 3) Add basic test coverage for most dynamic array use-cases in Fortran. The commit contains the following tests: * Ensure that values of Fortran dynamic arrays can be evaluated correctly in various ways and states. * Ensure that Fortran primitives can be evaluated correctly when used as a dynamic array. * Dynamic arrays passed to subroutines and handled in different ways inside the routine. * Ensure that the ptype of dynamic arrays in Fortran can be printed in GDB correctly. * Ensure that dynamic arrays in different states (allocated/associated) can be evaluated. * Dynamic arrays passed to functions and returned from functions. * History values of dynamic arrays can be accessed and printed again with the correct values. * Dynamic array evaluations using MI protocol. * Sizeof output of dynamic arrays in various states. The patch was tested using the test suite on Ubuntu 12.04 64bit. gdb/ChangeLog: * dwarf2read.c (set_die_type): Add read of DW_AT_allocated and DW_AT_associated. * f-typeprint.c: New include of typeprint.h (f_print_type): Add check for allocated/associated status of type. (f_type_print_varspec_suffix): Add check for allocated/associated status of type. * gdbtypes.c (create_array_type_with_stride): Add check for valid data location of type in case allocated or associated attributes are set. Length of an array should be only calculated if allocated or associated is resolved as true. (is_dynamic_type_internal): Add check for allocated/ associated. (resolve_dynamic_array): Evaluate allocated/associated properties. * gdbtypes.h (enum dynamic_prop_node_kind): <DYN_PROP_ALLOCATED> <DYN_PROP_ASSOCIATED>: New enums. (TYPE_ALLOCATED_PROP, TYPE_ASSOCIATED_PROP): New macros. (type_not_allocated): New function. (type_not_associated): New function. * valarith.c (value_subscripted_rvalue): Add check for allocated/associated. * valprint.c: New include of typeprint.h. (valprint_check_validity): Add check for allocated/associated. (value_check_printable): Add check for allocated/ associated. * typeprint.h (val_print_not_allocated): New function. (val_print_not_associated): New function. * typeprint.c (val_print_not_allocated): New function. (val_print_not_associated): New function. gdb/testsuite/ChangeLog: * gdb.fortran/vla-alloc-assoc.exp: New file. * gdb.fortran/vla-datatypes.exp: New file. * gdb.fortran/vla-datatypes.f90: New file. * gdb.fortran/vla-history.exp: New file. * gdb.fortran/vla-ptype-sub.exp: New file. * gdb.fortran/vla-ptype.exp: New file. * gdb.fortran/vla-sizeof.exp: New file. * gdb.fortran/vla-sub.f90: New file. * gdb.fortran/vla-value-sub-arbitrary.exp: New file. * gdb.fortran/vla-value-sub-finish.exp: New file. * gdb.fortran/vla-value-sub.exp: New file. * gdb.fortran/vla-value.exp: New file. * gdb.fortran/vla-ptr-info.exp: New file. * gdb.mi/mi-vla-fortran.exp: New file. * gdb.mi/vla.f90: New file.
