2013-10-30Report overflow on PowerPC64 @h and @ha relocations.Alan Modra2-0/+12
This changes the behaviour of @h and @ha on PowerPC64 to report errors on 32-bit overflow. The motivation for this change is that on PowerPC64, most uses of @h and @ha modifiers and their corresponding relocations are to build up 32-bit offsets. We'd like to know when such offsets overflow. Only rarely do people use @h or @ha with the high 32-bit modifiers to build a 64-bit constant. Those uses will now need to use two new modifiers, @high and @higha, if the constant isn't known at assembly time. For now, we won't report overflow at assembly time.. This also fixes an error when applying some of the HIGHER and HIGHEST relocations. include/elf/ * ppc64.h (R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA, R_PPC64_TPREL16_HIGH, R_PPC64_TPREL16_HIGHA, R_PPC64_DTPREL16_HIGH, R_PPC64_DTPREL16_HIGHA): New.
