2016-12-13Don't add PHDR for objcopy/strip or ld script specifying PHDRSAlan Modra1-0/+5
HPPA64 needs to add a DT_PHDR header for shared libs. That's fine when linking but shouldn't happen for strip/objcopy. Also PHDR must come first so there's no need to look at all program headers. bfd/ * elf64-hppa.c (elf64_hppa_modify_segment_map): Don't add PHDR for objcopy/strip or when a ld script specifies PHDRS. ld/ * testsuite/ld-elf/nobits-1.d: Remove xfail for hppa64. * testsuite/ld-elf/note-1.d: Likewise. * testsuite/ld-elf/note-2.d: Likewise.
2016-12-13Don't fudge p_vaddr when PHDR in segmentAlan Modra1-0/+5
RX does horrible fudges to PT_LOAD p_vaddr, that affect the testsuite and mean the target won't support dynamic objects. The latter probably doesn't matter too much since RX is an embedded target, but it's easy to stop some of the fudges in order to reduce special cases for RX in the testsuite. The changes make sense in isolation too. bfd/ * elf32-rx.c (elf32_rx_modify_program_headers): Don't adjust segments that include the ELF file header or program headers. ld/ * testsuite/ld-elf/flags1.d: Run for RX. * testsuite/ld-scripts/phdrs.exp: Likewise. * testsuite/ld-scripts/pr14962.d: Likewise. * testsuite/ld-scripts/pr14962-2.d: Likewise.

2016-12-03PowerPC64 dot-symbol compatibility bugfixesAlan Modra1-0/+37
Lots of fixes for the compatibility code that handles linking of -mcall-aixdesc code (or that generated by 12 year old gcc) with current ELFv1 ABI code. 1) A reference to a dot-symbol in an object file wasn't satisfied by a function descriptor in later object files. 2) The as-needed code had bit-rotted; Shared libs now need a strong reference to be counted as needed. 3) --gc-sections involving dot-symbols was broken, needing func_desc_adjust to be run early and lots of other fixes. bfd/ * elf64-ppc.c (struct ppc_link_hash_entry): Delete "was_undefined".

(ppc64_elf_gc_mark_hook): Mark descriptor. (func_desc_adjust): Don't make fake function descriptor syms strong here. Exit earlier on non-dotsyms. Take note of elf.dynamic flag when deciding whether a dynamic function descriptor might be needed. Transfer elf.dynamic and set elf.needs_plt. Move plt regardless of visibility. Make descriptor dynamic if entry sym is dynamic, not for other cases. (ppc64_elf_func_desc_adjust): Don't run func_desc_adjust if already done.

2016-11-30PR20886, looping in ppc64_elf_size_stubsAlan Modra1-0/+6
The PR20886 binary is large enough that there are two stub sections servicing .text (which is 88M). It so happens that between one iteration of sizing and the next that one stub section grows while the other shrinks. Since one section is always growing, the loop never terminates. This patch changes the algorithm to not update previous size on shrinking, once we go past a certain number of iterations.

This reverts commit b19753ce31da347605dfa903c6fd2158e2444f0d. As it turns out, GCC (and the assembler) needs additional work in order to support negative GOT offsets in 64-bit sparc. This is breaking TLS Local Dynamic in position-independent code.

2016-11-16Fix PR20789 - relaxation with negative valued diff relocsSenthil Kumar Selvaraj1-0/+10
Fix issues with diff relocs that have a negative value i.e. sym2 - sym1 where sym2 is lesser than sym1. The assembler generates a diff reloc with symbol as start of section and addend as sym2 offset, and encodes assembly time difference at the reloc offset. The existing relaxation logic adjusts addends if the relaxed insn lies between symbol and addend. That doesn't work for diff relocs where sym2 is less than sym1 *and* the relaxed insn happens to be between sym2 and sym1. Fix the problems by 1. Using signed handling of the difference value (bfd_signed_vma instead of bfd_vma, bfd_{get,set}_signed_xxx instead of bfd_{get,set}_xxx). 2. Not assuming sym2 is bigger than sym1. It instead computes the actual addresses and sets the lower and higher addresses as start and end addresses respectively and then sees if insn is between start and end. 3. Creating a new function elf32_avr_adjust_reloc_if_spans_insn to centralize reloc adjustment, and ensuring diff relocs get adjusted correctly even if their sym + addend doesn't overlap a relaxed insn. It also removes a redundant variable did_pad. It is never set if did_shrink is TRUE, and the code does a early return if did_shrink is FALSE. bfd/ChangeLog 2016-11-15 Senthil Kumar Selvaraj <senthil_kumar.selvaraj@atmel.com> PR ld/20789 * bfd/elf32-avr.c (elf32_avr_adjust_diff_reloc_value): Do signed manipulation of diff value, and don't assume sym2 is less than sym1.
