From e67ad678a1e75d69343e4270305c3bf390922362 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Thu, 17 Feb 2011 06:42:57 +0000 Subject: [Ada] Fix unconstrained packed array size When ada-lang transforms an array descriptor type (an XUP structure) into an array type, the size of the array type is computed by using the element size, and multiplying it by the number of elements in that array. This does not work, however, for packed arrays, where the *packed* size in bits needs to be used. This usually does not cause any problem, because we end up reading more memory than needed. However, we have observed on LynxOS a memory error while trying to read the entire array, because the larger-than-needed read tried to read past the end of the stack into inaccessible memory. This patch fixes the problem by correctly computing the array size in bytes in the case of packed arrays. gdb/ChangeLog: * ada-lang.c (ada_type_of_array): Fix the size of the array in the case of an unconstrained packed array. gdb/testsuite/ChangeLog: * gdb.ada/packed_array: Expand testcase to test printing of unconstrained packed array. --- gdb/testsuite/ChangeLog | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'gdb/testsuite/ChangeLog') diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index e3315ad..bcafab8 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,5 +1,10 @@ 2011-02-17 Joel Brobecker + * gdb.ada/packed_array: Expand testcase to test printing of + unconstrained packed array. + +2011-02-17 Joel Brobecker + * gdb.dwarf2/dw2-ranges.exp: Simplify using clean_restart. 2011-02-16 Pedro Alves -- cgit v1.1
