Better overflow checking for powerpc32 relocations 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.

Better overflow checking for powerpc64 relocations 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.

Create the second PLT for BND relocations Intel MPX introduces 4 bound registers, which will be used for parameter passing in x86-64. Bound registers are cleared by branch instructions. Branch instructions with BND prefix will keep bound register contents. This leads to 2 requirements to 64-bit MPX run-time: 1. Dynamic linker (ld.so) should save and restore bound registers during symbol lookup. 2. Change the current 16-byte PLT0: ff 35 08 00 00 00 pushq GOT+8(%rip) ff 25 00 10 00 jmpq *GOT+16(%rip) 0f 1f 40 00 nopl 0x0(%rax) and 16-byte PLT1: ff 25 00 00 00 00 jmpq *name@GOTPCREL(%rip) 68 00 00 00 00 pushq $index e9 00 00 00 00 jmpq PLT0 which clear bound registers, to preserve bound registers. We use 2 new relocations: to mark branch instructions with BND prefix. When linker sees any R_X86_64_PC32_BND or R_X86_64_PLT32_BND relocations, it switches to a different PLT0: ff 35 08 00 00 00 pushq GOT+8(%rip) f2 ff 25 00 10 00 bnd jmpq *GOT+16(%rip) 0f 1f 00 nopl (%rax) to preserve bound registers for symbol lookup and it also creates an external PLT section, .pl.bnd. Linker will create a BND PLT1 entry in .plt: 68 00 00 00 00 pushq $index f2 e9 00 00 00 00 bnd jmpq PLT0 0f 1f 44 00 00 nopl 0(%rax,%rax,1) and a 8-byte BND PLT entry in .plt.bnd: f2 ff 25 00 00 00 00 bnd jmpq *name@GOTPCREL(%rip) 90 nop Otherwise, linker will create a legacy PLT1 entry in .plt: 68 00 00 00 00 pushq $index e9 00 00 00 00 jmpq PLT0 66 0f 1f 44 00 00 nopw 0(%rax,%rax,1) and a 8-byte legacy PLT in .plt.bnd: ff 25 00 00 00 00 jmpq *name@GOTPCREL(%rip) 66 90 xchg %ax,%ax The initial value of the GOT entry for "name" will be set to the the "pushq" instruction in the corresponding entry in .plt. Linker will resolve reference of symbol "name" to the entry in the second PLT, .plt.bnd. Prelink stores the offset of pushq of PLT1 (plt_base + 0x10) in GOT[1] and GOT[1] is stored in GOT[3]. We can undo prelink in GOT by computing the corresponding the pushq offset with GOT[1] + (GOT offset - &GOT[3]) * 2 Since for each entry in .plt except for PLT0 we create a 8-byte entry in .plt.bnd, there is extra 8-byte per PLT symbol. We also investigated the 16-byte entry for .plt.bnd. We compared the 8-byte entry vs the the 16-byte entry for .plt.bnd on Sandy Bridge. There are no performance differences in SPEC CPU 2000/2006 as well as micro benchmarks. Pros: No change to undo prelink in dynamic linker. Only 8-byte memory overhead for each PLT symbol. Cons: Extra .plt.bnd section is needed. Extra 8 byte for legacy branches to PLT. GDB is unware of the new layout of .plt and .plt.bnd. bfd/ * elf64-x86-64.c (elf_x86_64_bnd_plt0_entry): New.

ppc476 icache bug workaround This implements a work-around for an icache bug on 476 that can cause execution of stale instructions when control falls through from one page to the next.
