Alan Modra	93d1b056cb	Rewrite ppc32 backend .sdata and .sdata2 handling 1) _SDA_BASE_ and _SDA2_BASE_ and defined automatically, in a similar manner to the way _GLOBAL_OFFSET_TABLE_ is handled. It's a little more complicated to remove the symbols because _SDA_BASE_ needs to be there if either .sdata or .sbss is present, and similarly for _SDA2_BASE. 2) The linker created .sdata and .sdata2 sections used for R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early. Nowadays we strip unneeded sections from the output, so it isn't necessary to delay creating the sections. 3) The output section for targets of various SDA relocs is now checked as per the ABI(s). We previously allowed .sdata.foo and similar, most likely because at some stage we were checking input sections. Also, the patch fixes a long-standing bug in size_input_sections that affects the values of symbols defined in stripped input sections.

Alan Modra	93ee1e3683	PR16867, linking object with separate debug file This teaches the DWARF2 find_line functions how to deal with separate debug relocatable object files. Also fixes a major bug: When _bfd_dwarf2_slurp_debug_info was split out, place_sections ran after .debug_info was relocated. This defeated the whole purpose of place_sections. See the comment I added before place_sections. Fixes some minor bugs too: - place_sections didn't set VMA for alloc but non-load sections (bss). - zero size sections can have symbols, so they need their VMA set too. - last_vma was incorrectly adjusted. - my last change to place_sections left VMA unchanged for .debug_info when the linker has mapped input to output sections, but this is wrong since bfd_simple_get_relocated_section_contents unmaps debug sections.

Alan Modra	cd0449ab05	PR ld/16787, stale dwarf2 stash Throw away the dwarf2 stash if it becomes invalid due to section VMAs changing. It would be nice to reclaim all the bfd_alloc memory here when we throw away the stash, perhaps by putting everything we alloc on a private dwarf2 objalloc, but I haven't done that with this patch. I've also fixed a problem with bfd_perform_relocation losing reloc addends, which meant a second or subsequent look at debug info sections did not properly relocate the sections. I can't see why bfd_perform_relocation should need to change addends except for ld -r, and the history (`985fca12`, `e98e6ec1`) doesn't help much. Finally, the patch tweaks place_sections to avoid unnecessary work. If we've mapped input to output sections, then input section VMA isn't used so there's not much point in adjusting it. Incidentally, this also means place_sections isn't effective in all cases. PR ld/16787 * dwarf2.c (struct dwarf2_debug): Add sec_vma field.

Kwok Cheung Yeung	cb22ccf411	This patch causes local GOT entries addressed via a 16-bit index to be placed towards the front of local GOT space, while entries addressed via a 32-bit index are placed towards the rear. Provided that there are fewer than ~16K local GOT entries addressed via a 16-bit index in total, this should eliminate any relocation overflows caused by such GOT entries being allocated beyond the addressable range. bfd/ * elfxx-mips.c (struct mips_got_info): Delete assigned_gotno field. Add assigned_low_gotno and assigned_high_gotno fields. (mips_elf_create_local_got_entry): Update out-of-space condition.

(mips_elf_set_global_gotidx): Replace uses of assigned_gotno with assigned_low_gotno. (mips_elf_multi_got): Initialize assigned_low_gotno and assigned_high_gotno in secondary GOTs.

Marcus Shawcroft	fa85fb9a1b	[AArch64] Fix off by one error in instruction relaxation mask. The AArch64 TLSDESC to IE relaxation code uses a bit mask intended to ensure that destination register in a relaxed ldr instruction is always X0. The mask has an off by one error resulting in the most significant bit of the destination register being retained in the relaxed instruction. The issue generally appears when the compiler emits TLS accesses code under high register pressure resulting in a broken code sequence.	12 years ago

Nick Clifton	32ae0d80cd	PE32+ binaries that use addresses > 1^32 have a problem in that the linker converts some address expressions into absolute values, but the PE format only stores absolutes as 32-bits. This is a partial solution which attempts to convert such absolute values back to section relative ones instead. It fails for symbols like __image_base and ImageBase__, but it is unclear as to whether these values are ever actually used by applications. PR ld/16821 * peXXigen.c (abs_finder): New function. (_bfd_XXi_swap_sym_out): For absolute symbols with values larger than 1^32 try to convert them into section relative values instead.	12 years ago

Alan Modra	b4ab436423	ppc476 icache workaround fix for bctr I got the ppc476 workaround wrong. bctr (and bctrl) as the last instruction in a page can hit the icache bug if the preceding mtctr insn is close by, and the destination is in the first few instructions on the next page. This scenario can occur with code generated by gcc to implement switch statements, or in code generated to call by function pointer. To prevent the bctr problem it is also necessary to remove other instructions that otherwise would be safe. bfd/ * elf32-ppc.c (ppc_elf_relocate_section): Remove bctr from list of safe ppc476 insns at end of page.
