Report overflow on PowerPC64 @h and @ha relocations.
|
|
|
01917d |
|
|
|
01917d |
This changes the behaviour of @h and @ha on PowerPC64 to report errors
|
|
|
01917d |
on 32-bit overflow. The motivation for this change is that on
|
|
|
01917d |
PowerPC64, most uses of @h and @ha modifiers and their corresponding
|
|
|
01917d |
relocations are to build up 32-bit offsets. We'd like to know when
|
|
|
01917d |
such offsets overflow. Only rarely do people use @h or @ha with the
|
|
|
01917d |
high 32-bit modifiers to build a 64-bit constant. Those uses will now
|
|
|
01917d |
need to use two new modifiers, @high and @higha, if the constant isn't
|
|
|
01917d |
known at assembly time. For now, we won't report overflow at assembly
|
|
|
01917d |
time..
|
|
|
01917d |
|
|
|
01917d |
This also fixes an error when applying some of the HIGHER and HIGHEST
|
|
|
01917d |
relocations.
