2015-07-10ppc476 linker workaround shared lib fixesAlan Modra6-0/+71
When building a shared lib from non-PIC objects, we'll get dynamic text relocations. These need to move with any insns we move. Otherwise the dynamic reloc will modify the branch, resulting in crashes and other unpleasant behaviour. Also, ld -r --ppc476-workaround used with sufficiently aligned PIC objects needs a fix for emitted REL16 relocs. bfd/ * elf64-ppc.c (ppc_elf_relocate_section): Move dynamic text relocs with insns moved by --ppc476-workaround. Correct output of REL16 relocs. ld/testsuite/ * ld-powerpc/ppc476-shared.s, * ld-powerpc/ppc476-shared.lnk, * ld-powerpc/ppc476-shared.d, * ld-powerpc/ppc476-shared2.d: New tests. * ld-powerpc/powerpc.exp: Run them.
2015-07-10Non-alloc sections don't belong in PT_LOAD segmentsAlan Modra2-7/+14
Taking them out showed a bug in the powerpc64 backend with .branch_lt being removed from output_bfd but not from previously set up segment section maps. Removing the bfd sections meant their sh_flags (and practically everything else) remaining zero, ie. not SHF_ALLOC, triggering complaints about "`.branch_lt' can't be allocated in segment". include/elf/ * internal.h (ELF_SECTION_IN_SEGMENT_1): Ensure PT_LOAD and similar segments only contain alloc sections. ld/ * emultempl/ppc64elf.em (gld${EMULATION_NAME}_after_allocation): Call gld${EMULATION_NAME}_map_segments regardless of need_laying_out.

2015-07-10Rewrite relro adjusting codeAlan Modra4-42/+49
The linker tries to put the end of the last section in the relro segment exactly on a page boundary, because the relro segment itself must end on a page boundary. If for any reason this can't be done, padding is inserted. Since the end of the relro segment is typically between .got and .got.plt, padding effectively increases the size of the GOT. This isn't nice for targets and code models with limited GOT addressing. The problem with the current code is that it doesn't cope very well with aligned sections in the relro segment. When making .got aligned to a 256 byte boundary for PowerPC64, I found that often the initial alignment attempt failed and the fallback attempt to be less than adequate. This is a particular problem for PowerPC64 since the distance between .got and .plt affects the size of plt call stubs, leading to "stubs don't match calculated size" errors. So this rewrite takes a direct approach to calculating a new relro base. Starting from the last section in the segment, we calculate where it must start to position its end on the boundary, or as near as possible considering alignment requirements. The new start then becomes the goal for the previous section to end, and so on for all sections. This of course ignores the possibility that user scripts will place . = ALIGN(xxx); in the relro segment, or provide section address expressions. In those cases we might fail, but the old code probably did too, and a fallback is provided. ld/ * ldexp.h (struct ldexp_control): Delete dataseg.min_base. Add data_seg.relro_offset. * ldexp.c (fold_binary <DATA_SEGMENT_ALIGN>): Don't set min_base. (fold_binary <DATA_SEGMENT_RELRO_END>): Do set relro_offset. * ldlang.c (lang_size_sections): Rewrite code adjusting relro segment base to line up last section on page boundary.

2015-02-11Correct PowerPC64 local-dynamic TLS linker optimizationAlan Modra6-0/+186
The linker hardcoded r3 into a local-dynamic to local-exec TLS optimization sequence. This is normally the case since r3 is required as a parameter to (the optimized out) __tls_get_addr call. However, it is possible for a compiler, LLVM in this case, to set up the parameter value in another register then copy it to r3 before the call. When fixing this problem, I noticed that ppc32 had another bug when optimizing away one of the TLS insns to a nop. The patch also tidies a mask used by global-dynamic to initial-exec TLS optimization, to just select the fields needed. Leaving the offset in the instruction wasn't a bug since it will be overwritten anyway. bfd/ * elf64-ppc.c (ppc64_elf_relocate_section): Correct GOT_TLSLD optimization.

2015-02-11ld: Don't evaluate unneeded PROVIDE expressions.Andrew Burgess11-2/+93
When creating a linker mapfile (using -Map=MAPFILE), we previously would always try to evaluate the expression from a PROVIDE statement. However, this is not always safe, consider: PROVIDE (foo = 0x10); PROVIDE (bar = foo); In this example, if neither 'foo' or 'bar' is needed, then while generating the linker mapfile evaluating the expression for 'foo' is harmless (just the value 0x10). However, evaluating the expression for 'bar' requires the symbol 'foo', which is undefined. This used to cause a fatal error. This patch changes the behaviour, so that when the destination of the PROVIDE is not defined (that is the PROVIDE is not going to provide anything) the expression is not evaluated, and instead a special string is displayed to indicate that the linker is discarding the PROVIDE statement. This change not only fixes the spurious undefined symbol error, but also means that a user can now tell if a PROVIDE statement has provided anything by inspecting the linker mapfile, something that could not be done before. ld/ChangeLog: * ldlang.c (print_assignment): Only evaluate the expression for a PROVIDE'd assignment when the destination is being defined. Display a special message for PROVIDE'd symbols that are not being provided. ld/testsuite/ChangeLog: * ld-scripts/provide-4.d: New file. * ld-scripts/provide-4-map.d: New file. * ld-scripts/provide-4.t: New file. * ld-scripts/provide-5.d: New file. * ld-scripts/provide-5.s: New file. * ld-scripts/provide-5-map.d: New file. * ld-scripts/provide-5.t: New file. * ld-scripts/provide.exp: Run the provide-4.d and provide-5.d tests.
2015-02-11ld/testing: run_dump_test can now check linker mapfiles.Andrew Burgess4-9/+41
Add a new option 'map' to the ld run_dump_test mechanism. When the 'map' option is given run_dump_test will ensure that there is a -Map=MAPFILE present in the linker command line, adding one if needed. The MAPFILE is then compared with the file passed to the new 'map' option using the regexp_diff function. This should make it slightly easier to write tests that check the linker mapfile output. The only test I found that already compares mapfile content is updated to use the new mechanism. ld/testsuite/ChangeLog: * ld-scripts/overlay-size.d: Add 'map' option. * ld-scripts/overlay-size.exp: Remove manual check of mapfile. * lib/ld-lib.exp (run_dump_test): Add support for new 'map' option, checking linker mapfile output.
2015-02-11Fix garbage collection of common symbolsAlan Modra13-34/+50
Running lang_common before garbage collection means slightly less work in garbage collection code, since common symbols should no longer appear there. It does have the side effect of keeping linker script symbols (at least those defined outside of sections) global too, hence some testsuite churn. bfd/ PR 17165 * elf-bfd.h (ELF_COMMON_DEF): Note that this might be true for linker script assignments too. * elflink.c (elf_gc_sweep_symbol): Don't drop ELF_COMMON_DEF syms.

2015-02-11Don't create .eh_frame_hdr on shared lib bfdAlan Modra2-1/+9
If no object files have .eh_frame, but some shared library does, then ld creates a .eh_frame_hdr section using the shared library bfd. This is silly since shared library .eh_frame sections don't contribute to the output .eh_frame and thus no .eh_frame_hdr is needed. Also, the bfd section list and count is cleared for shared libraries, and a zero section count used as a flag in lang_check to omit a call to bfd_merge_private_bfd_data for shared libraries. If we create a section on a shared lib bfd then ld will wrongly attempt to merge the shared library private bfd data.

2014-12-19[MIPS] When calculating a relocation using an undefined weak symbol don't ↵Andrew Bennett6-0/+110
check for overflow. In MIPS the relocation calculation only ignores the overflow checks for undefined weak symbols on relocations associated with j/jal. This patch extends this to the relocations used by the: b* instructions; pc/gp relative symbol offsets; and the lwpc/ldpc MIPS r6 instructions. bfd/ * elfxx-mips.c (mips_elf_calculate_relocation): Only check for overflow on non-weak undefined symbols. ld/testsuite/ * ld-mips-elf/mips-elf.exp: Add in undefined weak overflow tests for o32, n32 and n64. * ld-mips-elf/undefweak-overflow.s: New test. * ld-mips-elf/undefweak-overflow.d: New test. * ld-mips-elf/undefweak-overflow-n32.d: New test. * ld-mips-elf/undefweak-overflow-n64.d: New test.
2014-12-13Handle weak alias for PIE with copy relocH.J. Lu6-0/+60
When there is a weak symbol with a real definition, the processor independent code will have arranged for us to see the real definition first.
