Add support for a MIPS specific .MIPS.xhash section.
This patch is a reimplementation of [1] which was submitted in 2015 by Neil Schellenberger. Copyright issue was sorted out [2] last year. It proposed a new section (.gnu.xhash) and related dynamic tag (DT_GNU_XHASH). The new section would be virtually identical to the existing .gnu.hash except for the translation table (xlat) which would contain correct MIPS .dynsym indexes corresponding to the hashvals in chains. This is because MIPS ABI imposes a different ordering on the dynsyms than the one expected by the .gnu.hash section. Another addition would be a leading word (ngnusyms) which would contain the number of entries in the translation table. In this patch, the new section name and dynamic tag are changed to reflect the fact that the section should be treated as MIPS-specific (.MIPS.xhash and DT_MIPS_XHASH). This patch addresses the alignment issue as reported in [3], which is caused by the leading word added to the .MIPS.xhash section. Leading word is removed in this patch, and the number of entries in the translation table is now calculated using DT_MIPS_SYMTABNO dynamic tag (this is addressed by the corresponding glibc patch). Suggestions on coding style in [4] were taken into account. Existing GNU hash testcase was covered, and another one was added in the MIPS part of the testsuite. The other major change is reserving MIPS ABI version 5 for .MIPS.xhash, marking the need of support for .MIPS.xhash in the dynamic linker (again, addressed in the corresponding glibc patch). This is something which I am not sure of, especially after reading [5]. I am confused on whether this ABI version is reserved for IFUNC, or it can be used for this purpose.

gas/ELF: don't accumulate .type settings
Recently a patch was submitted for a Xen Project test harness binary to override the compiler specified @object to @func (see [1]). In a reply I suggested we shouldn't make ourselves dependent on currently unspecified behavior of gas here: It accumulates all requests, and then bfd/elf.c:swap_out_syms(), in an apparently ad hoc manner, prioritizes certain flags over others. Make the behavior predictable: Generally the last .type is what counts. Exceptions are directives which set multiple bits (TLS, IFUNC, and UNIQUE): Subsequent directives requesting just the more generic bit (i.e. FUNC following IFUNC) won't clear the more specific one. Warn about incompatible changes, except from/to STT_NOTYPE. Also add a new target hook, which hppa wants to use right away afaict. In the course of adding the warning I ran into two ld testsuite failures. I can only assume that it was a copy-and-paste mistake that lead to the same symbol having its type set twice.

PR24511, nm should not mark symbols in .init_array as "t"
This patch restricts the section names matched in coff_section_type, a function that translates section names to symbol type, and arranges to translate section flags to symbol type before looking at names. The latter change resulted in various test failures due to improper section flags being used in tests, and by the plugin support, so fix that too. The new test fails on many ELF targets that lack .init/fini_array in their scripts. I've just xfailed those. pru-elf oddly defines __init_array_begin rather than __init_array_start. I've left that target as a FAIL, and pj-elf too which reports an error for undefined weak symbols. bfd/ PR 24511 * syms.c (coff_section_type): Only allow '.', '$' and numeric following the standard section names.

Use better test for usable compiler in ld testsuite.
The ld testsuite includes numerous tests that depend on being able to compile and link programs with the C compiler. Some of these tests use [which $CC] to check for the presence of the compiler before proceeding with the test, but run_ld_link_exec_tests and run_cc_link_tests give ERRORs if compilation fails. Also, even if $CC is defined and present, it may not be usable due to missing libraries, etc. This patch adds a new procedure check_compiler_available that attempts to build an empty program and caches the result. Uses of [which $CC] are replaced with calls to this procedure, and run_ld_link_exec_tests and run_cc_link_tests now also guard attempts to use $CC. 2019-04-24 Sandra Loosemore <sandra@codesourcery.com> ld/ * testsuite/config/default.exp: Use [check_compiler_available] instead of [which $CC]. * testsuite/ld-auto-import/auto-import.exp: Likewise. * testsuite/ld-cygwin/exe-export.exp: Likewise. * testsuite/ld-elf/audit.exp: Likewise. * testsuite/ld-elf/compress.exp: Likewise. * testsuite/ld-elf/dwarf.exp: Likewise. * testsuite/ld-elf/elf.exp: Likewise. * testsuite/ld-elf/indirect.exp: Likewise. * testsuite/ld-elf/linux-x86.exp: Likewise. * testsuite/ld-elf/shared.exp: Likewise. * testsuite/ld-elf/tls.exp: Likewise. * testsuite/ld-elf/wrap.exp: Likewise. * testsuite/ld-elfcomm/elfcomm.exp: Likewise. * testsuite/ld-elfvers/vers.exp: Likewise. * testsuite/ld-elfvsb/elfvsb.exp: Likewise. * testsuite/ld-elfweak/elfweak.exp: Likewise. * testsuite/ld-gc/gc.exp: Likewise. * testsuite/ld-i386/i386.exp: Likewise. * testsuite/ld-i386/no-plt.exp: Likewise. * testsuite/ld-i386/tls.exp: Likewise. * testsuite/ld-ifunc/ifunc.exp: Likewise. * testsuite/ld-mn10300/mn10300.exp: Likewise. * testsuite/ld-pe/pe-compile.exp: Likewise. * testsuite/ld-pe/pe-run.exp: Likewise. * testsuite/ld-pe/pe-run2.exp: Likewise. * testsuite/ld-pie/pie.exp: Likewise. * testsuite/ld-plugin/lto.exp: Likewise. * testsuite/ld-plugin/plugin.exp: Likewise. * testsuite/ld-scripts/crossref.exp: Likewise. * testsuite/ld-sh/sh.exp: Likewise. * testsuite/ld-shared/shared.exp: Likewise. * testsuite/ld-size/size.exp: Likewise. * testsuite/ld-srec/srec.exp: Likewise. * testsuite/ld-undefined/undefined.exp: Likewise. * testsuite/ld-unique/unique.exp: Likewise. * testsuite/ld-x86-64/mpx.exp: Likewise. * testsuite/ld-x86-64/no-plt.exp: Likewise. * testsuite/ld-x86-64/tls.exp: Likewise. * testsuite/ld-x86-64/x86-64.exp: Likewise. * testsuite/lib/ld-lib.exp (run_ld_link_exec_tests): Call check_compiler_available before trying to use the compiler.

Fix some dlx fails
Generic linker ELF targets using CREATE_OBJECT_SYMBOLS in their scripts run into a problem. The file symbols are created by _bfd_generic_link_output_symbols in each object file, in the section corresponding to the CREATE_OBJECT_SYMBOLS section, typically .text. If it so happens that the output .text section is stripped due to being empty, then elf.c:assign_section_numbers won't assign an ELF section number and swap_out_syms will report "unable to find equivalent output section" for the object symbols. Fix this by always keeping an output section with CREATE_OBJECT_SYMBOLS. * ldlang.c (lang_size_sections_1): Set SEC_KEEP on create_object_symbols_section. * testsuite/ld-elf/pr22319.d: Don't xfail dlx. |

elf: Add PT_GNU_PROPERTY segment type
Linkers group input note sections with the same name into one output note section with the same name. One output note section is placed in one PT_NOTE segment. New linkers merge all input .note.gnu.property sections into one output .note.gnu.property section with a single NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment. Since older linkers treat input .note.gnu.property section as a generic note section and just concatenate all input .note.gnu.property sections into one output .note.gnu.property section without merging them, we may see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which are invalid. GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such that linker sets the bit for non-relocatable outputs. But it isn't sufficient: 1. It doesn't cover generic properties. 2. When -mx86-used-note=yes is passed to x86 assembler, the GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED property in object file and older linkers generate invalid NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit set. I am proposing the following changes: 1. Add PT_GNU_PROPERTY segment type: # define PT_GNU_PROPERTY (PT_LOOS + 0x474e553) which covers .note.gnu.property section. 2.

ELF ld -r scripts
"ld -r" generally should not combine object file sections with
different names. For example, "ld -r" should not combine ".text",
".text.hot" and ".text.cold" into an output ".text" section. An
exception needs to be made for linker created sections, for example,
branch trampoline sections that might be created even for ld -r.
"ld -r" also should not define symbols in linker scripts. Any
definitions are likely to conflict with those defined at final link.
A MEMORY spec is also not needed for ld -r.

Separate header PT_LOAD for -z separate-code
This patch, along with previous patches in the series, supports putting the ELF file header and program headers in a PT_LOAD without sections. Logic governing whether headers a loaded has changed a little: The primary reason to include headers is now the presence of SIZEOF_HEADERS in a linker script. However, to support scripts that may have reserved space for headers by hand, we continue to add headers whenever the first section address is past the end of headers modulo page size. include/ * bfdlink.h (struct bfd_link_info): Add load_phdrs field. bfd/ * elf-nacl.c (nacl_modify_segment_map): Cope with header PT_LOAD lacking sections. * elf.c (_bfd_elf_map_sections_to_segments): Assume file and program headers are required when info->load_phdrs.

ld insert_os_after ignoring first assignment
Some time ago the pr19593 test was xfailed for alpha. This turned out to be the wrong course of action since the test exposed a bug in orphan section placement. On alpha, orphan sections were being inserted before ". = SIZEOF_HEADERS" due to the test having two assignments, and on alpha, an output section statement from -Ttext-segment being passed to ld. * ldlang.c (insert_os_after): Clear ignore_first on assignment to dot, not any assignment.

Remove run_dump_test support for objcopy as a dump program
We have three copies of run_dump_test in the testsuite. This is a first step towards consolidating them. A few tests use objcopy to convert to verilog or srec output, then check that output is as expected. Those tests can just as easily use objdump, keeping the set of dump programs (addr2line, nm, objdump, readelf, size) separate from utilities under test. That in turn makes auto-detecting the dump program possible in more places. binutils/ * testsuite/binutils-all/group-7a.d, * testsuite/binutils-all/group-7b.d, * testsuite/binutils-all/group-7c.d, * testsuite/binutils-all/symbols-1.d, * testsuite/binutils-all/symbols-2.d, * testsuite/binutils-all/symbols-3.d, * testsuite/binutils-all/symbols-4.d: Remove DUMPPROG. gas/ * testsuite/gas/mri/char.d: Don't objcopy to srec, objdump instead. * testsuite/gas/mri/float.d: Likewise. * testsuite/lib/gas-defs.exp (run_dump_test): Remove support for objcopy as a dump tool. ld/ * testsuite/ld-elf/interleave-0.d, * testsuite/ld-elf/interleave-4.d: Don't objcopy to srec, objdump instead. * testsuite/ld-gc/all-debug-sections.d, * testsuite/ld-scripts/provide-4.d, * testsuite/ld-scripts/provide-5.d, * testsuite/ld-scripts/provide-6.d, * testsuite/ld-scripts/provide-7.d, * testsuite/ld-scripts/provide-8.d, * testsuite/ld-scripts/segment-start.d: Remove PROG, specify nm instead. * testsuite/lib/ld-lib.exp (run_dump_test): Remove support for objcopy as a dump tool. |

Add support for the C_SKY series of processors.
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc.
This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about.

x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if needed
When -z separate-code, which is enabled by default for Linux/x86, is used to create executable, ld won't place any data in the code-only PT_LOAD segment. If there are no data sections placed before the code-only PT_LOAD segment, the program headers won't be mapped into any PT_LOAD segment. When the executable tries to access it (based on the program header address passed in AT_PHDR), it will lead to segfault. This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if there may be no data sections before the text section so that the first PT_LOAD segment won't be code-only and will contain the program header. Testcases are adjusted to either pass "-z noseparate-code" to ld or discard the .note.gnu.property section. A Linux/x86 run-time test is added. bfd/ PR ld/23428 * elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): If the separate code program header is needed, make sure that the first read-only PT_LOAD segment has no code by adding a GNU_PROPERTY_X86_ISA_1_USED note. ld/ PR ld/23428 * testsuite/ld-elf/linux-x86.S: New file. * testsuite/ld-elf/linux-x86.exp: Likewise. * testsuite/ld-elf/pr23428.c: Likewise. * testsuite/ld-elf/sec64k.exp: Pass "-z noseparate-code" to ld for Linux/x86 targets. * testsuite/ld-i386/abs-iamcu.d: Likewise. * testsuite/ld-i386/abs.d: Likewise. * testsuite/ld-i386/pr12718.d: Likewise. * testsuite/ld-i386/pr12921.d: Likewise. * testsuite/ld-x86-64/abs-k1om.d: Likewise. * testsuite/ld-x86-64/abs-l1om.d: Likewise. * testsuite/ld-x86-64/abs.d: Likewise. * testsuite/ld-x86-64/pr12718.d: Likewise. * testsuite/ld-x86-64/pr12921.d: Likewise. * testsuite/ld-linkonce/zeroeh.ld: Discard .note.gnu.property section. * testsuite/ld-scripts/print-memory-usage.t: Likewise. * testsuite/ld-scripts/size-2.t: Likewise. * testsuite/lib/ld-lib.exp (run_ld_link_exec_tests): Use ld to create executable if language is "asm". |

MIPS/LD: Fix crashing with a discarded dynamic relocation section
Fix a crash that occurs in `_bfd_mips_elf_finish_dynamic_sections' if a dynamic relocation section has been created, but marked to be discarded by an assignment to the /DISCARD/ output section in a linker script. In that case the output section is the absolute section, which has no ELF section data attached, so trying to set its `sh_size' parameter causes a null pointer dereference. This is only done as the value for the DT_RELSZ dynamic entry is being set, so fix the problem by not creating DT_REL, DT_RELSZ or DT_RELENT dynamic entries in the first place if the dynamic relocation section will not be output, as with no dynamic relocation data present these would not serve their purpose anyway. Add a generic ELF test case to verify that no dynamic relocation data is reported in the dynamic segment. bfd/ * elfxx-mips.c (_bfd_mips_elf_size_dynamic_sections): Do not create DT_REL, DT_RELSZ or DT_RELENT dynamic entries if the dynamic relocation section will be discarded from output. (_bfd_mips_elf_finish_dynamic_sections) <DT_RELSZ>: Assert that the dynamic relocation section will be retained in output. ld/ * testsuite/ld-elf/reloc-discard.d: New test. * testsuite/ld-elf/reloc-discard.ld: New test linker script. * testsuite/ld-elf/reloc-discard.s: New test source. |
