When trying to evaluate an expression which adds a pointer and
an integral, the evaluation succeeds if the pointer is on
the left handside of the operator, but not when it is on the right
handside:
(gdb) p something'address + 0
$1 = (system.address) 0x613418 <pck.something>
(gdb) p 0 + something'address
Argument to arithmetic operation not a number or boolean.
Same issue when doing subtractions:
(gdb) p something'address - 0
$2 = (system.address) 0x613418 <pck.something>
(gdb) p 0 - something'address
Argument to arithmetic operation not a number or boolean.
This patch enhances the Ada expression evaluator to handle
these two situations.
gdb/ChangeLog:
* ada-lang.c (ada_evaluate_subexp) <BINOP_ADD>: Add handling
of the case where the second operand is a pointer.
<BINOP_SUB>: Likewise.
gdb/testsuite/ChangeLog:
* gdb.ada/addr_arith: New testcase.
Tested on x86_64-linux.
