2019-07-13[GOLD] PowerPC notoc eh_frameAlan Modra1-9/+16
When generating notoc call and branch stubs without the benefit of pc-relative insns, the stubs need to use LR to access the run time PC. All LR changes must be described in .eh_frame if we're to support unwinding through asynchronous exceptions. That's what this patch does. The patch has gone through way too many iterations. At first I attempted to add multiple FDEs, one for each stub. That ran into difficulties with do_plt_fde_location which is only capable of setting the address of a single FDE per Output_data section, and with removing any FDEs added on a previous do_relax pass. Removing FDEs (git commit be897fb774) went overboard in matching the FDE contents. That means either stashing the contents created for add_eh_frame_for_plt to use when calling remove_eh_frame_for_plt, or recreating contents on the fly (*) just to remove FDEs. In fact, FDE content matching is quite unnecesary. FDEs added by a previous do_relax pass are those with u_.from_linker.post_map set. So they can easily be recognised just by looking at that flag. This patch keeps that part of the multiple FDE changes. In the end I went for just one FDE per stub group to describe the call stubs. That's reasonably efficient for the common case of only needing to describe the __tls_get_addr_opt call stub. We don't expect to be making many calls using notoc stubs without pc-relative insns. *) Which has it's own set of problems. The contents must be recreated using the old stub layout, but .eh_frame size can affect stub requirements so you need to temporarily keep the old .eh_frame size when creating new stubs, then reset .eh_frame size before adding new FDEs. * ehframe.cc (Fde::operator==): Delete.

2017-08-01[GOLD] PowerPC recreate eh_frame for stubs on each relax passAlan Modra1-0/+13
There is a very small but non-zero probability that a stub group contains stubs on one relax pass, but does not on the next. In that case we would get an FDE covering a zero length address range. (Actually, it's even worse. Alignment padding for stubs can mean the address for the non-existent stubs is past the end of the original section to which stubs are attached, and due to the way do_plt_fde_location calculates the length we can get a negative length.) Fixing this properly requires removing the FDE. Also, I have been implementing the __tls_get_addr_opt support for gold, and that stub needs something other than the default FDE. The necessary FDE will depend on the offset to the __tls_get_addr_opt stub, which of course can change during relaxation. That means at the very least, rewriting the FDE on each pass, possibly changing the FDE size. I think that is better done by completely recreating PLT eh_frame FDEs. * ehframe.cc (Fde::operator==): New.

2015-03-09Fix failure in exception_static_test.Cary Coutant1-1/+9
Because the __EH_FRAME_BEGIN__ symbol is provided in an empty .eh_frame section in crtbeginT.o, if crt1.o has a non-empty .eh_frame section, we place all optimized .eh_frame sections into the output section ahead of the __EH_FRAME_BEGIN__ symbol, which breaks EH for statically-linked binaries. This patch fixes the problem by delaying the attachment of the optimized .eh_frame sections to the output section until we see the end marker section (or to the end of pass 1 if we never see an end marker). gold/ PR gold/14675 * ehframe.cc (Eh_frame::add_ehframe_input_section): Change return type; return enum indicating whether .eh_frame section is empty, optimizable, unrecognized, or an end marker.

2014-09-02Fix problem with optimization of .eh_frame section and --sort-section option.Cary Coutant1-3/+4
When --sort-section=name is used, gold will sort the linker-generated contents of .eh_frame (after optimization) after the endcap provided by crtendS.o. This causes two problems: the .eh_frame_hdr section is generated assuming that the optimized .eh_frame contents will be placed at the very beginning of the section, and the endcap no longer appears at the end of the section. This patch fixes the first problem by adjusting FDE offsets to take into account the actual starting offset within the output section, and fixes the second problem by sorting linker-generated (Output_section_data) sections based on the name of the output section. gold/ PR gold/17005 * ehframe.cc (Fde::write): Add output_offset parameter.
