* Remove unnecessary _bfd_new_bfd initialisationAlan Modra2013-11-022-15/+4

* Simplify ppc64 code setting toc_off.Alan Modra2013-11-022-35/+23
| | | | | | | | | | | | | | | Every function has a nominal toc pointer value, even if it isn't used, so set toc_off for every code section to the value used in that object file. The thinking here was that if a code section didn't use the toc it could use the previous object file's toc pointer value. It can, but doing so is only a gain if functions in that section are called mostly from previous objects sharing the same toc. We lose if the functions in question are called mostly from the current object or following objects, and it's a good bet they will probably mostly be called from the current object. * elf64-ppc.c (ppc64_elf_next_input_section): Always set toc_off to value for object file.

* Replace DT_PPC_TLSOPT with DT_PPC_OPT.Alan Modra2013-10-303-6/+24
| | | | | | | | | | | | | | | | | | | | | | | This removes the DT_PPC_TLSOPT/DT_PPC64_TLSOPT dynamic tag and replaces it with DT_PPC_OPT/DT_PPC64_OPT tag to provide the same functionality and more.

* ELFv2 stub, plt and glink changesAlan Modra2013-10-302-119/+220
| | | | | | | | | | | | | | | | | | | An ELFv2 PLT entry is simply the address of the target function rather than three (or two) words to specify entry, toc and static chain. PLT call stubs are correspondingly simpler and need no thread safety barrier. The glink resolver stub and branch table also is simplified, a change that could be applied to ELFv1 too, but isn't as yet. * elf64-ppc.c (PLT_ENTRY_SIZE, PLT_INITIAL_ENTRY_SIZE): Add htab parameter and adjust for ELFv2.

* Report overflow on PowerPC64 @h and @ha relocations.Alan Modra2013-10-305-32/+191
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the behaviour of @h and @ha on PowerPC64 to report errors on 32-bit overflow. The motivation for this change is that on PowerPC64, most uses of @h and @ha modifiers and their corresponding relocations are to build up 32-bit offsets. We'd like to know when such offsets overflow. Only rarely do people use @h or @ha with the high 32-bit modifiers to build a 64-bit constant. Those uses will now need to use two new modifiers, @high and @higha, if the constant isn't known at assembly time. For now, we won't report overflow at assembly time.. This also fixes an error when applying some of the HIGHER and HIGHEST relocations. include/elf/ * ppc64.h (R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA, R_PPC64_TPREL16_HIGH, R_PPC64_TPREL16_HIGHA, R_PPC64_DTPREL16_HIGH, R_PPC64_DTPREL16_HIGHA): New.

* ld/ELF: refine fake STT_FILE symbol emissionJan Beulich2013-10-292-16/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no real need to emit these always: They're needed only if we indeed want to emit a localized symbol. Hence defer emission until we at least did the basic early checks that would lead to no such symbol getting emitted. This in particular avoids emitting such a symbol in the majority of (if not all) "ld -r" cases. I hope my set of cross build tests caught all the test cases needing adjustment - please forgive if I missed a few. bfd/ 2013-10-29 Jan Beulich <jbeulich@suse.com> * elflink.c (struct elf_outext_info): Add field file_sym_done.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes gdb PR symtab/15597. The bug is that the .gnu_debugaltlink section includes the build-id of the alt file, but gdb does not use it. This patch fixes the problem by changing gdb to do what it ought to always have done: verify the build id of the file found using the filename in .gnu_debugaltlink; and if that does not match, try to find the correct debug file using the build-id and debug-file-directory. This patch touches BFD. Previously, gdb had its own code for parsing .gnu_debugaltlink; I changed it to use the BFD functions after those were introduced. However, the BFD functions are incorrect -- they assume that .gnu_debugaltlink is formatted like .gnu_debuglink. However, it it is not. Instead, it consists of a file name followed by the build-id -- no alignment, and the build-id is not a CRC. Fixing this properly is a bit of a pain. But, because separate_alt_debug_file_exists just has a FIXME for the build-id case, I did not fix it properly. Instead I introduced a hack. This leaves BFD working just as well as it did before my patch. I'm willing to do something better here but I could use some guidance as to what. It seems that the build-id code in BFD is largely punted on. FWIW gdb is the only user of bfd_get_alt_debug_link_info outside of BFD itself. I moved the build-id logic out of elfread.c and into a new file. This seemed cleanest to me. Writing a test case was a bit of a pain. I added a couple new features to the DWARF assembler to handle this.
