* PowerPC64 stubs don't match calculated sizeAlan Modra2017-09-192-6/+7
| | | | | | | | | | | | | | | | | | | | After the PR 21411 fix, the linker generated .eh_frame for ppc64 glink can be edited by the generic code. The sequence of events goes something like: 1) Some object file adds .eh_frame aligned to 8, making the output .eh_frame aligned to at least 8, so linker generated .eh_frame FDE is padded to an 8 byte boundary. 2) All .eh_frame past the glink .eh_frame is garbage collected. 3) Generic code detects that last FDE (the glink .eh_frame) doesn't need to be padded to an 8 byte boundary, reducing size from 88 to 84. 4) elf64-ppc.c check fails. PR 21441 * elf64-ppc.c (ppc64_elf_build_stubs): Don't check glink_eh_frame size. (cherry picked from commit 25516cc573ff3551a7ac0538e1d3de5811c7199e)
* PR22150, ld keeps a version reference for gc'd symbolsAlan Modra2017-09-192-117/+118
| | | | | | | | | | | | | | | | | | | | | elf_gc_sweep_symbol should run after verdefs are calculated, since the verdef code creates symbols for the versions. However, elf_gc_sweep_symbol needs to run before verrefs so as to not emit useless verrefs for symbols that are gc'd. I've also removed a _bfd_elf_link_renumber_dynsyms calls added by Maciej after I fussed about it when reviewing. On further examination the call appears to be unnecessary. Looking at renumber_dynsyms also made me realize that the test to exclude .gnu.version has been wrong since 2016-04-26 (git commit d5486c4372), so fix that too. PR 22150 * elflink.c (bfd_elf_size_dynamic_sections): Garbage collect symbols before calculating verrefs. Don't renumber dynsyms after gc. Exclude .gnu.version when zero or one dynsym. Localize some vars and reindent. (cherry picked from commit 3d13f3e9bda5aada68915f5d958f731ae79ed41d)
* [GOLD, PowerPC] Add --no-stub-group-multiAlan Modra2017-09-192-2/+8
| | | | | | | | | | | | | | | The trouble with stubs per output section is that ppc32 uses a plt stub as the address of a global function. This needs to be unique, otherwise we'll get multiple addresses for a function. Obviously this is only a partial solution, since ppc32 will get multiple stubs when code is larger than 33M. A proper fix will involve selecting a unique stub to use for non-branch relocs. * options.h (stub-group-multi): Default to true. Add --no-stub-group-multi.

The old behaviour is had by using a negative parameter. The default is also changed to align plt stub code by default to 32 byte boundaries, the point being to get better bctr branch prediction on power8 and power9 hardware. bfd/ * elf64-ppp.c (plt_stub_pad): Handle positive and negative plt_stub_align. ld/ * ld.texinfo (--plt-align): Describe new behaviour of option. * emultempl/ppc64elf.em (params): Default plt_stub_align to 5. * testsuite/ld-powerpc/powerpc.exp: Pass --no-plt-align for selected tests. * testsuite/ld-powerpc/relbrlt.d: Pass --no-plt-align. * testsuite/ld-powerpc/elfv2so.d: Adjust expected output.
