Better overflow checking for powerpc32 relocations
|
|
|
01917d |
|
|
|
01917d |
Similar to the powerpc64 patch, this improves overflow checking in
|
|
|
01917d |
elf32-ppc.c. Many reloc "howto" entries needed fixes, some just
|
|
|
01917d |
cosmetic.
|
|
|
01917d |
|
|
|
01917d |
The patch also fixes the R_PPC_VLE_SDA21 reloc application code, which
|
|
|
01917d |
was horribly broken. In fact, it may still be broken since Power ISA
|
|
|
01917d |
2.07 says e_li behaves as
|
|
|
01917d |
RT <- EXTS(li20 1:4 || li20 5:8 || li20 0 || li20 9:19)
|
|
|
01917d |
where li20 is a field taken from bits 17..20, 11..15, 21..31 of the
|
|
|
01917d |
instruction. Freescale VLEPEM says differently, and I assume
|
|
|
01917d |
correctly, that
|
|
|
01917d |
RT <- EXTS(li20 0:3 || li20 4:8 || li20 9:19)
|
|
|
01917d |
The VLE_SDA21 relocation description matches this too.
|
|
|
01917d |
|
|
|
01917d |
Now the VLE_SDA21 relocation specifies in the case where e_addi16 is
|
|
|
01917d |
converted to e_li for symbols in .PPC.EMB.sdata0 or .PPC.EMB.sbss0
|
|
|
01917d |
(no base register), that the field is restricted to 16 bits, with the
|
|
|
01917d |
sign bit being propagated to the top 4 bits. I don't see the sense in
|
|
|
01917d |
restricting the value like this, so have allowed the full 20 bit
|
|
|
01917d |
signed value. This of course is compatible with the reloc description
|
|
|
01917d |
in that values in the 16 bit signed range will result in exactly the
|
|
|
01917d |
same insn field as when the reloc description is followed to the
|
|
|
01917d |
letter.
|
|
|
01917d |
|
|
|
01917d |
* elf32-ppc.c (ppc_elf_howto_raw): Correct overflow check for
|
|
|
01917d |
many relocations. Correct bitsize and rightshift too for a number
|
|
|
01917d |
of VLE relocs. Describe R_PPC_VLE_SDA21 and R_PPC_VLE_SDA21_LO.
|
|
|
01917d |
Correct dst_mask on R_PPC_VLE_SDA21_LO.
|
|
|
01917d |
(ppc_elf_vle_split16): Tidy, delete unnecessary prototype.
|
|
|
01917d |
(ppc_elf_relocate_section): Modify overflow test for 16-bit
|
|
|
01917d |
fields in instructions to signed/unsigned according to whether
|
|
|
01917d |
the field takes a signed or unsigned value. Tidy vle split16 code.
|
|
|
01917d |
Correct R_PPC_VLE_SDA21 and R_PPC_VLE_SDA21_LO handling.
