From 7ba71655a425ac44721f97cc0ad7922ca15bce43 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Tue, 28 Feb 2017 08:32:36 +1030 Subject: [PATCH] PowerPC addpcis fix This came up because I was looking at ld/tmpdir/addpcis.o and noticed the odd addends on REL16DX_HA. They ought to both be -4. The error crept in due REL16DX_HA howto being pc-relative (as indeed it should be), and code at gas/write.c:1001 after this comment /* Make it pc-relative. If the back-end code has not selected a pc-relative reloc, cancel the adjustment we do later on all pc-relative relocs. */ *not* cancelling the pc-relative adjustment. So I've made a dummy non-relative split reloc so that the generic code handles this, rather than attempting to add hacks later in md_apply_fix which would not be very robust. Having the new internal reloc also makes it easy to support addpcis rx,sym@ha as an equivalent to addpcis rx,(sym-0f)@ha 0: The patch also fixes overflow checking, which must test whether the addi will overflow too since @l relocs don't have any overflow check. Lastly, since I was poking at md_apply_fix, I arranged to have the generic gas/write.c code emit errors for subtraction expressions where we lack reloc support. include/ * elf/ppc64.h (R_PPC64_16DX_HA): New.
