33 * Trap number defines.
35 * On this architecture (powerpc) the trap numbers are used as load
36 * displacements and thus must not be 4- or 8-byte aligned.
38 * NOTE: In trap_init() we have a check whether the offset of
39 * java_arrayheader.data[0] is greater than the largest displacement
40 * defined below. Otherwise normal array loads/stores could trigger
44 #define TRAP_INSTRUCTION_IS_LOAD 1
47 TRAP_NullPointerException = 0,
48 TRAP_ArithmeticException = 1,
49 TRAP_ArrayIndexOutOfBoundsException = 2,
50 TRAP_ArrayStoreException = 3,
52 /* Don't use 4 (could be a normal load offset). */
54 TRAP_ClassCastException = 5,
55 TRAP_CHECK_EXCEPTION = 6,
58 /* Don't use 8 (could be a normal load offset). */
64 #endif /* _MD_TRAP_H */
68 * These are local overrides for various environment variables in Emacs.
69 * Please do not remove this and leave it at the end of the file, where
70 * Emacs will automagically detect them.
