http://sourceware.org/ml/gdb-patches/2012-08/msg00562.html Subject: [PATCH] Expand fortran array bounds sizes to LONGEST --MP_/90J7bck2fqDySEX9JkZtaqL Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Disposition: inline Hi, Range bounds for a gdb type can have LONGEST values for low and high bounds. Fortran range bounds functions however use only int. The larger ranges don't compile by default on gcc, but it is possible to override the check in the compiler by using -fno-range-check. As a result, this check is necessary so that we don't print junk in case of an overflow. Attached patch does this expansion and also includes a test case that verifies that the problem is fixed. I have also verified on x86_64 that this patch does not cause any regressions. Regards, Siddhesh gdb/ChangeLog: * f-lang.h (f77_get_upperbound): Return LONGEST. (f77_get_lowerbound): Likewise. * f-typeprint.c (f_type_print_varspec_suffix): Expand UPPER_BOUND and LOWER_BOUND to LONGEST. Use plongest to format print them. (f_type_print_base): Expand UPPER_BOUND to LONGEST. Use plongest to format print it. * f-valprint.c (f77_get_lowerbound): Return LONGEST. (f77_get_upperbound): Likewise. (f77_get_dynamic_length_of_aggregate): Expand UPPER_BOUND, LOWER_BOUND to LONGEST. (f77_create_arrayprint_offset_tbl): Likewise. testsuite/ChangeLog: * gdb.fortran/array-bounds.exp: New test case. * gdb.fortran/array-bounds.f: New test case. --MP_/90J7bck2fqDySEX9JkZtaqL Content-Type: text/x-patch Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=f77-bounds.patch Index: gdb-7.5.0.20120926/gdb/f-lang.h =================================================================== --- gdb-7.5.0.20120926.orig/gdb/f-lang.h 2012-11-07 22:12:39.000000000 +0100 +++ gdb-7.5.0.20120926/gdb/f-lang.h 2012-11-07 22:52:02.688632498 +0100 @@ -66,9 +66,9 @@ enum f90_range_type extern char *real_main_name; /* Name of main function. */ extern int real_main_c_value; /* C_value field of main function. */ -extern int f77_get_upperbound (struct type *); +extern LONGEST f77_get_upperbound (struct type *); -extern int f77_get_lowerbound (struct type *); +extern LONGEST f77_get_lowerbound (struct type *); extern void f77_get_dynamic_array_length (struct type *); Index: gdb-7.5.0.20120926/gdb/f-typeprint.c =================================================================== --- gdb-7.5.0.20120926.orig/gdb/f-typeprint.c 2012-11-07 22:00:41.000000000 +0100 +++ gdb-7.5.0.20120926/gdb/f-typeprint.c 2012-11-07 22:52:02.689632497 +0100 @@ -182,7 +182,7 @@ f_type_print_varspec_suffix (struct type int show, int passed_a_ptr, int demangled_args, int arrayprint_recurse_level) { - int upper_bound, lower_bound; + LONGEST upper_bound, lower_bound; /* No static variables are permitted as an error call may occur during execution of this function. */ @@ -212,7 +212,7 @@ f_type_print_varspec_suffix (struct type lower_bound = f77_get_lowerbound (type); if (lower_bound != 1) /* Not the default. */ - fprintf_filtered (stream, "%d:", lower_bound); + fprintf_filtered (stream, "%s:", plongest (lower_bound)); /* Make sure that, if we have an assumed size array, we print out a warning and print the upperbound as '*'. */ @@ -222,7 +222,7 @@ f_type_print_varspec_suffix (struct type else { upper_bound = f77_get_upperbound (type); - fprintf_filtered (stream, "%d", upper_bound); + fprintf_filtered (stream, "%s", plongest (upper_bound)); } if (TYPE_CODE (TYPE_TARGET_TYPE (type)) != TYPE_CODE_ARRAY) @@ -291,7 +291,7 @@ void f_type_print_base (struct type *type, struct ui_file *stream, int show, int level) { - int upper_bound; + LONGEST upper_bound; int index; QUIT; @@ -373,7 +373,7 @@ f_type_print_base (struct type *type, st else { upper_bound = f77_get_upperbound (type); - fprintf_filtered (stream, "character*%d", upper_bound); + fprintf_filtered (stream, "character*%s", plongest (upper_bound)); } break; Index: gdb-7.5.0.20120926/gdb/f-valprint.c =================================================================== --- gdb-7.5.0.20120926.orig/gdb/f-valprint.c 2012-11-07 22:09:29.000000000 +0100 +++ gdb-7.5.0.20120926/gdb/f-valprint.c 2012-11-07 22:52:21.888604907 +0100 @@ -57,7 +57,7 @@ LONGEST f77_array_offset_tbl[MAX_FORTRAN #define F77_DIM_BYTE_STRIDE(n) (f77_array_offset_tbl[n][0]) -int +LONGEST f77_get_lowerbound (struct type *type) { f_object_address_data_valid_or_error (type); @@ -68,7 +68,7 @@ f77_get_lowerbound (struct type *type) return TYPE_ARRAY_LOWER_BOUND_VALUE (type); } -int +LONGEST f77_get_upperbound (struct type *type) { f_object_address_data_valid_or_error (type); @@ -92,8 +92,8 @@ f77_get_upperbound (struct type *type) static void f77_get_dynamic_length_of_aggregate (struct type *type) { - int upper_bound = -1; - int lower_bound = 1; + LONGEST upper_bound = -1; + LONGEST lower_bound = 1; /* Recursively go all the way down into a possibly multi-dimensional F77 array and get the bounds.
