From cd859a2010670cdeaf184903224ae2fac65afd6a Mon Sep 17 00:00:00 2001 From: David Lecomber Date: Tue, 9 Sep 2003 16:51:54 +0000 Subject: [PATCH] Change array element access to something similar to way C works. The old method would drag in the entire array, then look for the single element. This method just gets the right element out instead. Saves memory, and saves a crash for array with (*) as one of the dimensions when it would previously have allocated (unsigned int) -1 bytes. --- gdb/eval.c | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-) diff --git a/gdb/eval.c b/gdb/eval.c index 914a552070..7b18723774 100644 --- a/gdb/eval.c +++ b/gdb/eval.c @@ -1666,10 +1666,6 @@ evaluate_subexp_standard (struct type *expect_type, offset_item = array_size_array[i] * offset_item + subscript_array[i]; - /* Construct a value node with the value of the offset */ - - arg2 = value_from_longest (builtin_type_f_integer, offset_item); - /* Let us now play a dirty trick: we will take arg1 which is a value node pointing to the topmost level of the multidimensional array-set and pretend @@ -1678,7 +1674,15 @@ evaluate_subexp_standard (struct type *expect_type, returns the correct type value */ VALUE_TYPE (arg1) = tmp_type; - return value_ind (value_add (value_coerce_array (arg1), arg2)); + + f77_get_dynamic_lowerbound (tmp_type, &lower); + + /* Construct a value node with the value of the offset */ + /* lower will get subtracted off in value_subscript, hence add it here */ + + arg2 = value_from_longest (builtin_type_f_integer, offset_item + lower); + + return value_subscript(arg1, arg2); } case BINOP_LOGICAL_AND: -- 2.34.1
