2017-09-10PowerPC64 --plt-alignAlan Modra1-1/+1
This changes the PowerPC64 --plt-align option to perform the usual alignment of code as suggested by its name, as well as the previous behaviour of padding so as to reduce boundary crossing. 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.

2017-07-07MIPS/LD: Fix a segfault from ELF `e_flags' access with non-ELF output BFDMaciej W. Rozycki1-6/+9
Fix a commit 861fb55ab50a ("Defer allocation of R_MIPS_REL32 GOT slots"), <https://sourceware.org/ml/binutils/2008-08/msg00096.html>, regression and a more recent: FAIL: ld-unique/pr21529 new LD test case failure, observed with all the relevant MIPS targets whenever the linker is invoked with one or more ELF inputs and the output format set to `binary'. The culprit is a segmentation fault caused in `mips_before_allocation' by a null pointer dereference, where an attempt is made to access the ELF file header's `e_flags' member, for the purpose of determining whether to produce a PLT and copy relocations, without first checking that the output BFD is ELF. The `e_flags' member is stored in BFD's private data pointed to by `tdep', which in the case of the `binary' BFD is null, causing the segmentation fault. With other non-ELF BFDs such as SREC `tdep' is not null and consequently no crash may happen and in that case random data will be interpreted as it was `e_flags'. Disable the access to `e_flags' then and all the associated checks and consequently never produce a PLT and copy relocations if output is not a MIPS ELF BFD, matching `_bfd_mips_elf_merge_private_bfd_data' that does not process `e_flags' in that case either and therefore does not let us decide here anyway if all the input objects included in the link are suitable for use with a PLT and copy relocations. ld/ * emultempl/mipself.em (mips_before_allocation): Avoid ELF processing if not MIPS ELF. * testsuite/ld-mips-elf/binary.d: New test. * testsuite/ld-mips-elf/binary.ld: New test linker script. * testsuite/ld-mips-elf/binary.s: New test source. * testsuite/ld-mips-elf/mips-elf.exp: Run the new test.

2017-06-16Rewrite __start and __stop symbol handlingAlan Modra1-57/+0
This arranges for __start and __stop symbols to be defined before garbage collection, for all target formats. That should allow the COFF and PE --gc-sections to keep a singleton orphan input section, a feature lost by 2017-06-13 commit cbd0eecf26. The fancier ELF treatment of keeping all input sections associated with a __start or __stop symbol, from 2015-10-23 commit 1cce69b9dc, is retained. .startof. and .sizeof. symbols are deliberately not defined before garbage collection, so these won't affect garbage collection of sections. The patch also ensures __start, __stop, .startof. and .sizeof. symbols are defined before target size_dynamic_sections is called, albeit with a preliminary value, so that target code doesn't need to cope with a symbol changing from undefined at size_dynamic_sections to defined at relocate_section. Also, a number of problems with the testcases have been fixed.

2017-06-13Always define referenced __start_SECNAME/__stop_SECNAMEH.J. Lu1-4/+60
Currently, linker will define __start_SECNAME and __stop_SECNAME symbols only for orphaned sections. However, during garbage collection, ELF linker marks all sections with references to __start_SECNAME and __stop_SECNAME symbols as used even when section SECNAME isn't an orphaned section and linker won't define __start_SECNAME nor __stop_SECNAME. And ELF linker stores the first input section whose name matches __start_SECNAME or __stop_SECNAME in u.undef.section for garbage collection. If these symbols are provided in linker script, u.undef.section is set to the section where they will defined by linker script, which leads to the incorrect output. This patch changes linker to always define referenced __start_SECNAME and __stop_SECNAME if the input section name is the same as the output section name, which is always true for orphaned sections, and SECNAME is a C identifier. Also __start_SECNAME and __stop_SECNAME symbols are marked as hidden by ELF linker so that __start_SECNAME and __stop_SECNAME symbols for section SECNAME in different modules are unique. For garbage collection, ELF linker stores the first matched input section in the unused vtable field. bfd/ PR ld/20022 PR ld/21557 PR ld/21562 PR ld/21571 * elf-bfd.h (elf_link_hash_entry): Add start_stop.

2017-06-01PPC64_OPT_LOCALENTRYAlan Modra1-22/+43
ELFv2 functions with localentry:0 are those with a single entry point, ie. global entry == local entry, and that have no requirement on r2 or r12, and guarantee r2 is unchanged on return. Such an external function can be called via the PLT without saving r2 or restoring it on return, avoiding a common load-hit-store for small functions. The optimization is attractive. The TOC pointer load-hit-store is a major reason why calls to small functions that need no register saves, or with shrink-wrap, no register saves on a fast path, are slow on powerpc64le. To be safe, this optimization needs ld.so support to check that the run-time matches link-time function implementation. If a function in a shared library with st_other localentry non-zero is called without saving and restoring r2, r2 will be trashed on return, leading to segfaults. For that reason the optimization does not happen for weak functions since a weak definition is a fairly solid hint that the function will likely be overridden. I'm also not enabling the optimization by default unless glibc-2.26 is detected, which should have the ld.so checks implemented. bfd/ * elf64-ppc.c (struct ppc_link_hash_table): Add has_plt_localentry0.

2017-04-04Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXXH.J. Lu1-1/+45
Mark an ALLOC section, which should be placed in special memory area, with SHF_GNU_MBIND. Its sh_info field indicates the special memory type. GNU_MBIND section names start with ".mbind" so that they are placed as orphan sections by linker. All input GNU_MBIND sections with the same sh_type, sh_flags and sh_info are placed in one output GNU_MBIND section. In executable and shared object, create a GNU_MBIND segment for each GNU_MBIND section and its segment type is PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is aligned at page boundary. The assembler syntax: .section .mbind.foo,"adx",%progbits ^ 0: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.foo,"adx",%progbits,0x1 ^ 1: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.bar,"adG",%progbits,.foo_group,comdat,0x2 ^ 2: Special memory type. | 'd' for SHF_GNU_MBIND. bfd/ * elf.c (get_program_header_size): Add a GNU_MBIND segment for each GNU_MBIND section and align GNU_MBIND section to page size.

2016-12-03PowerPC64 dot-symbol compatibility bugfixesAlan Modra1-1/+0
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".

2016-05-28Return void from linker callbacksAlan Modra1-6/+3
The ldmain.c implementation of these linker callback functions always return true, so any code handling a false return is dead. What's more, some of the bfd backends abort if ever a false return is seen, and there seems to be some confusion in gdb's compile-object-load.c. The return value was never meant to be "oh yes, a multiple_definition error occurred", but rather "out of memory or other catastrophic failure". This patch removes the status return on the callbacks that always return true. I kept the return status for "notice" because that one does happen to need to return "out of memory". include/ * bfdlink.h (struct bfd_link_callbacks): Update comments.
