2014-03-27Referencing a function's address on PowerPC64 ELFv2Alan Modra2-43/+75
ELFv2 needs to create plt entries in a non-PIC executable for an address reference to a function defined in a shared object. It's possible that an object file has no features that distinguish it as ELFv1 or ELFv2, eg. an object only containing data. Such files need to be handled like those that are known to be ELFv2. However, this unnecessarily creates plt entries for the analogous ELFv1 case, so arrange to set output abi version earlier, and use the output abi version to further distinguish ambiguous input files. bfd/ * elf64-ppc.c (ppc64_elf_check_relocs): Account for possibly needed plt entries when taking the address of functions for abiversion == 0 (ie. unknown) as well as abiversion == 2.

2014-03-08Better overflow checking for powerpc32 relocationsAlan Modra2-159/+189
Similar to the powerpc64 patch, this improves overflow checking in elf32-ppc.c. Many reloc "howto" entries needed fixes, some just cosmetic. The patch also fixes the R_PPC_VLE_SDA21 reloc application code, which was horribly broken. In fact, it may still be broken since Power ISA 2.07 says e_li behaves as RT <- EXTS(li20 1:4 || li20 5:8 || li20 0 || li20 9:19) where li20 is a field taken from bits 17..20, 11..15, 21..31 of the instruction. Freescale VLEPEM says differently, and I assume correctly, that RT <- EXTS(li20 0:3 || li20 4:8 || li20 9:19) The VLE_SDA21 relocation description matches this too. Now the VLE_SDA21 relocation specifies in the case where e_addi16 is converted to e_li for symbols in .PPC.EMB.sdata0 or .PPC.EMB.sbss0 (no base register), that the field is restricted to 16 bits, with the sign bit being propagated to the top 4 bits. I don't see the sense in restricting the value like this, so have allowed the full 20 bit signed value. This of course is compatible with the reloc description in that values in the 16 bit signed range will result in exactly the same insn field as when the reloc description is followed to the letter. * elf32-ppc.c (ppc_elf_howto_raw): Correct overflow check for many relocations. Correct bitsize and rightshift too for a number of VLE relocs. Describe R_PPC_VLE_SDA21 and R_PPC_VLE_SDA21_LO. Correct dst_mask on R_PPC_VLE_SDA21_LO. (ppc_elf_vle_split16): Tidy, delete unnecessary prototype. (ppc_elf_relocate_section): Modify overflow test for 16-bit fields in instructions to signed/unsigned according to whether the field takes a signed or unsigned value. Tidy vle split16 code. Correct R_PPC_VLE_SDA21 and R_PPC_VLE_SDA21_LO handling.
2014-03-08Better overflow checking for powerpc64 relocationsAlan Modra2-20/+54
R_PPC64_ADDR16 is used in three contexts: - .short data relocation - 16-bit signed insn fields, eg. addi - 16-bit unsigned insn fields, eg. ori In the first case we want to allow both signed and unsigned 16-bit values, the latter two ought to error if the field exceeds the range of values allowed for 16-bit signed and unsigned integers respectively. These conflicting requirements meant that ld had to choose the least restrictive overflow checks, and thus it is possible to construct testcases where an addi field overflows but is not reported by ld. Many relocations dealing with 16-bit insn fields have this problem. What's more, some relocations that are only ever used for signed fields of instructions woodenly copied the lax overflow checking of R_PPC64_ADDR16. bfd/ * elf64-ppc.c (ppc64_elf_howto_raw): Use complain_overflow_signed for R_PPC64_ADDR14, R_PPC64_ADDR14_BRTAKEN, R_PPC64_ADDR14_BRNTAKEN, R_PPC64_SECTOFF, R_PPC64_ADDR16_DS, R_PPC64_SECTOFF_DS, R_PPC64_REL16 entries.

I noticed GDB was failing to enable threading support for 32-bit AIX cores. I traced it to failure to read variables from libpthreads.a.
