2018-04-09PowerPC inline PLT call supportAlan Modra1-0/+4
In addition to the existing relocs we need two more to mark all instructions in the call sequence, PLTCALL on the call itself (plus the toc restore insn for ppc64), and PLTSEQ on others. All relocations in a particular sequence have the same symbol. Example ppc64 ELFv2 assembly: .reloc .,R_PPC64_PLTSEQ,puts std 2,24(1) addis 12,2,puts@plt@ha # .reloc .,R_PPC64_PLT16_HA,puts ld 12,puts@plt@l(12) # .reloc .,R_PPC64_PLT16_LO_DS,puts .reloc .,R_PPC64_PLTSEQ,puts mtctr 12 .reloc .,R_PPC64_PLTCALL,puts bctrl ld 2,24(1) Example ppc32 -fPIC assembly: addis 12,30,puts+32768@plt@ha # .reloc .,R_PPC_PLT16_HA,puts+0x8000 lwz 12,12,puts+32768@plt@l # .reloc .,R_PPC_PLT16_LO,puts+0x8000 .reloc .,R_PPC_PLTSEQ,puts+32768 mtctr 12 .reloc .,R_PPC_PLTCALL,puts+32768 bctrl Marking sequences like this allows the linker to convert them to nops and a direct call if the target symbol turns out to be local. When the call is __tls_get_addr, each relocation shown above is paired with an R_PPC*_TLSLD or R_PPC*_TLSGD reloc to additionally mark the sequence for possible TLS optimization. The TLSLD or TLSGD relocs are emitted first. include/ * elf/ppc.h (R_PPC_PLTSEQ, R_PPC_PLTCALL): Define. * elf/ppc64.h (R_PPC64_PLTSEQ, R_PPC64_PLTCALL): Define. bfd/ * elf32-ppc.c (ppc_elf_howto_raw): Add PLTSEQ and PLTCALL howtos.

2017-02-28PowerPC addpcis fixAlan Modra1-1/+5
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. Expand fake reloc comment. * elf/ppc.h (R_PPC_16DX_HA): Likewise. bfd/ * reloc.c (BFD_RELOC_PPC_16DX_HA): New. * elf64-ppc.c (ppc64_elf_howto_raw <R_PPC64_16DX_HA>): New howto.

This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs, makes the assembler warn about undefined tag values, and removes similar warnings from the linker. I think it is better to not warn in the linker about undefined tag values as future extensions to the tags then won't result in likely bogus warnings. This is consistent with the fact that an older linker won't warn on an entirely new tag. include/ * elf/ppc.h (Tag_GNU_Power_ABI_FP): Comment. bfd/ * elf-bfd.h (_bfd_elf_ppc_merge_fp_attributes): Declare. * elf32-ppc.c (_bfd_elf_ppc_merge_fp_attributes): New function.

2016-06-07PowerPC VLEAlan Modra1-0/+13
VLE is an encoding, not a particular processor architecture, so it isn't really proper to select insns based on PPC_OPCODE_VLE. For example {"evaddw", VX (4, 512), VX_MASK, PPCSPE|PPCVLE, PPCNONE, {RS, RA, RB}}, {"vaddubs", VX (4, 512), VX_MASK, PPCVEC|PPCVLE, PPCNONE, {VD, VA, VB}}, shows two insns that have the same encoding, both available with VLE. Enabling both with VLE means we can't disassemble the second variant even if -Maltivec is given rather than -Mspe. Also, we don't check user assembly against the processor type as well as we could. Another problem is that when using the VLE encoding, insns from the main ppc opcode table are not available, except those using opcode 4 and 31. Correcting this revealed two errors in the ld testsuite, use of "nop" and "rfmci" when -mvle. This patch fixes those problems in the opcode table, and removes PPCNONE. I find a plain 0 distracts less from other values. In addition, I've implemented code to recognize some machine values from the apuinfo note present in ppc32 objects. It's not a complete disambiguation since we're lacking info to detect newer chips, but what we have should help with disassembly. include/ * elf/ppc.h (APUINFO_SECTION_NAME, APUINFO_LABEL, PPC_APUINFO_ISEL, PPC_APUINFO_PMR, PPC_APUINFO_RFMCI, PPC_APUINFO_CACHELCK, PPC_APUINFO_SPE, PPC_APUINFO_EFS, PPC_APUINFO_BRLOCK, PPC_APUINFO_VLE: Define. opcodes/ * ppc-dis.c (ppc_opts): Delete extraneous parentheses.
