2014-02-03ppc476 icache bug workaroundAlan Modra2-21/+70
This implements a work-around for an icache bug on 476 that can cause execution of stale instructions when control falls through from one page to the next. The idea is to prevent such fall-through by replacing the last instruction on a page with a branch to a patch area containing the instruction, then branch to the next page. The patch also fixes a number of bugs in the existing support for long branch trampolines. bfd/ * elf32-ppc.c (struct ppc_elf_link_hash_table): Add params. Delete emit_stub_syms, no_tls_get_addr_opt. Update all uses. (ppc_elf_link_params): New function. (ppc_elf_create_glink): Align .glink to 64 bytes for ppc476 workaround. (ppc_elf_select_plt_layout): Remove plt_style and emit_stub_syms parameters. Use htab->params instead. (ppc_elf_tls_setup): Remove no_tls_get_addr_opt parameter.

2014-01-22Make assignments to dot keep an empty output section.Alan Modra19-38/+157
An assignment to dot in an output section that allocates space of course keeps the output section. Here, I'm changing the behaviour for assignments that don't allocate space. The idea is not so much to allow people to force output of an empty section with ". = .", but to fix cases where an otherwise empty section has padding added by an alignment expression that changes with relaxation or .eh_frame editing. Such a section might have zero size before relaxation and so be stripped incorrectly. ld/ * ld.texinfo (Output Section Discarding): Mention assigning to dot as a way of keeping otherwise empty sections. * ldexp.c (is_dot, is_value, is_sym_value, is_dot_ne_0, is_dot_plus_0, is_align_conditional): New predicates.

2014-01-21Check incompatible existing default symbol definitionH.J. Lu9-0/+90
After resolving a versioned reference, foo@VER1, to a default versioned definition, foo@@VER1, from a shared object, we also merge it with the existing regular default symbol definition, foo. When foo is IFUNC and foo@@VER1 aren't, we will merge 2 incompatible definitions. This patch avoids merging foo@@VER1 definition with foo definition if one is IFUNC and the other isn't.

It puts /usr/lib64 in linker scripts for all emulations, like --- /* Script for -z combreloc: combine and sort reloc sections */ OUTPUT_FORMAT("elf32-i386", "elf32-i386", "elf32-i386") OUTPUT_ARCH(i386) ENTRY(_start) SEARCH_DIR("/usr/x86_64-redhat-linux/lib32"); SEARCH_DIR("/usr/i386-redhat-linux/lib32"); SEARCH_DIR("/usr/lib6432"); SEARCH_DIR("/usr/local/lib32"); SEARCH_DIR("/lib32"); SEARCH_DIR("/usr/lib32"); SEARCH_DIR("/usr/i386-redhat-linux/lib"); SEARCH_DIR("/usr/lib64"); SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib"); SEARCH_DIR("/usr/lib"); --- /usr/lib6432 is odd and /usr/lib64 is wrong.

2014-01-16Tidy ld use of bfd_section userdata.Alan Modra4-53/+38
A long time ago ld made use of userdata to tie an output section to its lang_input_statement_struct object file. Some time later Joern made map file printing of symbols at lot faster, using userdata on input sections. That complicated allocation of userdata, and when the output section use disappeared a year later, the code wasn't properly cleaned up. This patch does that cleanup, and also tidies the symbol printing code to not allocate userdata where it won't be needed. We don't print symbols defined in the absolute section or in output sections. * ld.h (fat_section_userdata_type, get_userdata): Move to.. * ldlang.h (input_section_userdata_type, get_userdata): ..here. * ldlang.c (init_map_userdata): Delete.

2014-01-15non-PIC references to __ehdr_start in pie and sharedAlan Modra7-0/+44
Rather than hacking every backend to not discard dynamic relocations against an undefined hidden __ehdr_start, make it appear to be defined early. We want __ehdr_start hidden before size_dynamic_sections so that it isn't put in .dynsym, but we do need the dynamic relocations for a PIE or shared library with a non-PIC reference. Defining it early is wrong if we don't actually define the symbol later to its proper value. (In some cases we want to leave the symbol undefined, for example, when the ELF header isn't loaded, and we don't have this infomation available in before_allocation.) ld/ * emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation): Define __ehdr_start before size_dynamic_sections and restore afterwards. ld/testsuite/ * ld-elf/ehdr_start-shared.d: New. * ld-elf/ehdr_start-userdef.d: xfail frv. * ld-elf/ehdr_start-weak.d: Likewise. * ld-elf/ehdr_start.d: Likewise.
