Pierre-Marie de Rodat e6c2c623f7 [Ada] Fix handling of array renamings ... Compilers can materialize renamings of arrays (or of accesses to arrays) in Ada into variables whose types are references to the actual array types. Before this change, trying to use such an array renaming yielded an error in GDB: (gdb) print my_array(1) cannot subscript or call a record (gdb) print my_array_ptr(1) cannot subscript or call something of type `(null)' This behavior comes from bad handling for array renamings, in particular the OP_FUNCALL expression operator handling from ada-lang.c (ada_evaluate_subexp): in one place we turn the reference into a pointer, but the code that follows expect the value to be an array. This patch fixes how we handle references in call/subscript evaluation so that we turn these references into the actual array values instead of pointers to them. gdb/ChangeLog: * ada-lang.c (ada_evaluate_subexp) <OP_FUNCALL>: When the input value is a reference, actually dereference it in order to get the underlying value. gdb/testsuite/ChangeLog: * gdb.ada/array_ptr_renaming.exp: New testcase. * gdb.ada/array_ptr_renaming/foo.adb: New file. * gdb.ada/array_ptr_renaming/pack.ads: New file. Tested on x86_64-linux, no regression.		2015-09-23 22:14:18 +02:00
