2019-01-08run_dump_test source in build directoryAlan Modra3-27/+33
Some existing tests build .s and .d files for run_dump_test, using an absolute #source: line in the .d file. This patch changes that scheme a little to instead use "#source: ./..." in .d files rather than "#source: $objdir/...", which is more useful in cases where the .d file is not generated. This allows RX gas test files to be built in the build directory, rather than in a source directory (which might be read-only). binutils/ * testsuite/lib/binutils-common.exp (run_dump_test): Don't prepend $srcdir/$subdir to source file name if it starts with "./". gas/ * testsuite/gas/rx/rx.exp: Create generated test source in current directory. * testsuite/gas/rx/Xtod.d, * testsuite/gas/rx/abs.d, * testsuite/gas/rx/adc.d, * testsuite/gas/rx/add.d, * testsuite/gas/rx/and.d, * testsuite/gas/rx/bclr.d, * testsuite/gas/rx/bcnd.d, * testsuite/gas/rx/bfmov.d, * testsuite/gas/rx/bmcnd.d, * testsuite/gas/rx/bnot.d, * testsuite/gas/rx/bra.d, * testsuite/gas/rx/brk.d, * testsuite/gas/rx/bset.d, * testsuite/gas/rx/bsr.d, * testsuite/gas/rx/btst.d, * testsuite/gas/rx/clrpsw.d, * testsuite/gas/rx/cmp.d, * testsuite/gas/rx/dabs.d, * testsuite/gas/rx/dadd.d, * testsuite/gas/rx/dbt.d, * testsuite/gas/rx/dcmp.d, * testsuite/gas/rx/ddiv.d, * testsuite/gas/rx/div.d, * testsuite/gas/rx/divu.d, * testsuite/gas/rx/dmov.d, * testsuite/gas/rx/dmul.d, * testsuite/gas/rx/dneg.d, * testsuite/gas/rx/dpopm.d, * testsuite/gas/rx/dpushm.d, * testsuite/gas/rx/dround.d, * testsuite/gas/rx/dsqrt.d, * testsuite/gas/rx/dsub.d, * testsuite/gas/rx/dtoX.d, * testsuite/gas/rx/emaca.d, * testsuite/gas/rx/emsba.d, * testsuite/gas/rx/emul.d, * testsuite/gas/rx/emula.d, * testsuite/gas/rx/emulu.d, * testsuite/gas/rx/fadd.d, * testsuite/gas/rx/fcmp.d, * testsuite/gas/rx/fdiv.d, * testsuite/gas/rx/fmul.d, * testsuite/gas/rx/fsqrt.d, * testsuite/gas/rx/fsub.d, * testsuite/gas/rx/ftoi.d, * testsuite/gas/rx/ftou.d, * testsuite/gas/rx/gprel.d, * testsuite/gas/rx/int.d, * testsuite/gas/rx/itof.d, * testsuite/gas/rx/jmp.d, * testsuite/gas/rx/jsr.d, * testsuite/gas/rx/machi.d, * testsuite/gas/rx/maclh.d, * testsuite/gas/rx/maclo.d, * testsuite/gas/rx/max.d, * testsuite/gas/rx/min.d, * testsuite/gas/rx/mov.d, * testsuite/gas/rx/movco.d, * testsuite/gas/rx/movli.d, * testsuite/gas/rx/movu.d, * testsuite/gas/rx/msbhi.d, * testsuite/gas/rx/msblh.d, * testsuite/gas/rx/msblo.d, * testsuite/gas/rx/mul.d, * testsuite/gas/rx/mulhi.d, * testsuite/gas/rx/mullh.d, * testsuite/gas/rx/mullo.d, * testsuite/gas/rx/mvfacgu.d, * testsuite/gas/rx/mvfachi.d, * testsuite/gas/rx/mvfaclo.d, * testsuite/gas/rx/mvfacmi.d, * testsuite/gas/rx/mvfc.d, * testsuite/gas/rx/mvfcp.d, * testsuite/gas/rx/mvfdc.d, * testsuite/gas/rx/mvfdr.d, * testsuite/gas/rx/mvtacgu.d, * testsuite/gas/rx/mvtachi.d, * testsuite/gas/rx/mvtaclo.d, * testsuite/gas/rx/mvtc.d, * testsuite/gas/rx/mvtcp.d, * testsuite/gas/rx/mvtdc.d, * testsuite/gas/rx/neg.d, * testsuite/gas/rx/nop.d, * testsuite/gas/rx/not.d, * testsuite/gas/rx/opecp.d, * testsuite/gas/rx/or.d, * testsuite/gas/rx/pop.d, * testsuite/gas/rx/popc.d, * testsuite/gas/rx/popm.d, * testsuite/gas/rx/push.d, * testsuite/gas/rx/pushc.d, * testsuite/gas/rx/pushm.d, * testsuite/gas/rx/r-bcc.d, * testsuite/gas/rx/r-bra.d, * testsuite/gas/rx/racl.d, * testsuite/gas/rx/racw.d, * testsuite/gas/rx/rdacl.d, * testsuite/gas/rx/rdacw.d, * testsuite/gas/rx/revl.d, * testsuite/gas/rx/revw.d, * testsuite/gas/rx/rmpa.d, * testsuite/gas/rx/rolc.d, * testsuite/gas/rx/rorc.d, * testsuite/gas/rx/rotl.d, * testsuite/gas/rx/rotr.d, * testsuite/gas/rx/round.d, * testsuite/gas/rx/rstr.d, * testsuite/gas/rx/rte.d, * testsuite/gas/rx/rtfi.d, * testsuite/gas/rx/rts.d, * testsuite/gas/rx/rtsd.d, * testsuite/gas/rx/sat.d, * testsuite/gas/rx/satr.d, * testsuite/gas/rx/save.d, * testsuite/gas/rx/sbb.d, * testsuite/gas/rx/sccnd.d, * testsuite/gas/rx/scmpu.d, * testsuite/gas/rx/setpsw.d, * testsuite/gas/rx/shar.d, * testsuite/gas/rx/shll.d, * testsuite/gas/rx/shlr.d, * testsuite/gas/rx/smovb.d, * testsuite/gas/rx/smovf.d, * testsuite/gas/rx/smovu.d, * testsuite/gas/rx/sstr.d, * testsuite/gas/rx/stnz.d, * testsuite/gas/rx/stz.d, * testsuite/gas/rx/sub.d, * testsuite/gas/rx/suntil.d, * testsuite/gas/rx/swhile.d, * testsuite/gas/rx/tst.d, * testsuite/gas/rx/utof.d, * testsuite/gas/rx/wait.d, * testsuite/gas/rx/xchg.d, * testsuite/gas/rx/xor.d: Add #source line. ld/ * testsuite/ld-elf/sec64k.exp: Use . rather than $objdir in generated source file names. * testsuite/ld-m68k/m68k-got.exp: Likewise.

2018-12-14elf: Add PT_GNU_PROPERTY segment typeH.J. Lu28-157/+330
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. Remove GNU_PROPERTY_X86_UINT32_VALID. bfd/ PR ld/23900 * elf.c (get_program_header_size): Add a PT_GNU_PROPERTY segment for NOTE_GNU_PROPERTY_SECTION_NAME.

When discovering the statement lists via their header variable statement_list, file_chain and input_file_chain it can be confusing to figure out what they are for. They can point to the same initial statement and the relation between the next field they use is not obvious from the name. This commit adds comment for each of those statement list header to explain what they are for and what next field they use. It also rewrite the comment for the next fields to simply redirect the reader to the list header to avoid duplication of documentation. 2018-11-29 Thomas Preud'homme <thomas.preudhomme@linaro.org> ld/ * ldlang.c (statement_list): Document purpose and what next field it uses.

2018-11-27MIPS/LD: Accept high-part relocations in PIC code with absolute symbolsMaciej W. Rozycki12-0/+110
Accept R_MIPS_HI16, R_MIPS_HIGHER and R_MIPS_HIGHEST relocations and their compressed counterparts in PIC code where the symbol referred is absolute. Such an operation is meaningful, because an absolute symbol effectively is a constant the calculation of the value of which has been deferred to the static link time, and which is not going to change any further at the dynamic load time. Therefore there is no need ever to refuse the use of these relocations with such symbols, as the resulting run-time value observed by the program will be correct even in PIC code. This is not the case with R_MIPS_26 and its compressed counterparts, because the run-time value calculated by the instructions these relocations are used with depends on the address of the instruction itself, and that can change according to the base address used by the dynamic loader. Therefore these relocations have to continue being rejected in PIC code even with absolute symbols. This allows successful linking of code that relies on previous linker behavior up to commit 861fb55ab50a ("Defer allocation of R_MIPS_REL32 GOT slots"), <https://sourceware.org/ml/binutils/2008-08/msg00096.html>, which introduced the problematic check missing this special exception for absolute symbols. bfd/ * elfxx-mips.c (_bfd_mips_elf_check_relocs) <R_MIPS16_HI16> <R_MIPS_HI16, R_MIPS_HIGHER, R_MIPS_HIGHEST, R_MICROMIPS_HI16> <R_MICROMIPS_HIGHER, R_MICROMIPS_HIGHEST>: Also accept an absolute symbol in PIC code. ld/ * testsuite/ld-mips-elf/pic-reloc-0.d: New test. * testsuite/ld-mips-elf/pic-reloc-1.d: New test. * testsuite/ld-mips-elf/pic-reloc-2.d: New test. * testsuite/ld-mips-elf/pic-reloc-3.d: New test. * testsuite/ld-mips-elf/pic-reloc-4.d: New test. * testsuite/ld-mips-elf/pic-reloc-absolute-hi.ld: New test linker script. * testsuite/ld-mips-elf/pic-reloc-absolute-lo.ld: New test linker script. * testsuite/ld-mips-elf/pic-reloc-ordinary.ld: New test linker script. * testsuite/ld-mips-elf/pic-reloc-j.s: New test source. * testsuite/ld-mips-elf/pic-reloc-lui.s: New test source. * testsuite/ld-mips-elf/mips-elf.exp: Run the new tests.
2018-11-27LD: Convert `%P: %H:' to `%H:' in error messagesMaciej W. Rozycki2-3/+10
Similarly to commit 174d0a74a2e6 ("PowerPC/BFD: Convert `%P: %H:' to `%H:' in error messages") convert linker relocation error messages to use `%H:' rather `%P: %H:', removing inconsistent message composition like: $ cat reloc-j.s .text .globl foo .ent foo foo: j bar j bar .end foo $ cat reloc-j.ld SECTIONS { bar = 0x12345678; .text : { *(.text) } /DISCARD/ : { *(*) } } $ as -o reloc-j.o reloc-j.s $ ld -T reloc-j.ld -o reloc-j reloc-j.o ld: tmpdir/reloc-j.o: in function `foo': (.text+0x0): relocation truncated to fit: R_MIPS_26 against `bar' ld: (.text+0x8): relocation truncated to fit: R_MIPS_26 against `bar' $ where subsequent lines referring to issues within a single function have the name of the linker executable prepended, but the first one does not. As noted with the commit referred this breaks a GNU Coding Standard's requirement that error messages from compilers should look like this: source-file-name:lineno: message also quoted in `vfinfo' code handling these specifiers. Remove the linker name prefix then, making the messages now look like: $ ld -T reloc-j.ld -o reloc-j reloc-j.o tmpdir/reloc-j.o: in function `foo': (.text+0x0): relocation truncated to fit: R_MIPS_26 against `bar' (.text+0x8): relocation truncated to fit: R_MIPS_26 against `bar' $ instead. ld/ * ldmain.c (reloc_overflow): Use `%H:' rather than `%P: %H:' with `einfo'.

2018-11-27AArch64: Fix regression in Cortex A53 erratum when PIE. (PR ld/23904)Tamar Christina4-0/+100
The fix for PR ld/22263 causes TLS relocations using ADRP to be relaxed into MOVZ, however this causes issues for the erratum code. The erratum code scans the input sections looking for ADRP instructions and notes their location in the stream. It then later tries to find them again in order to generate the linker stubs. Due to the relaxation it instead finds a MOVZ and hard aborts. Since this relaxation is a valid one, and in which case the erratum no longer applies, it shouldn't abort but instead just continue. This changes the TLS relaxation code such that when it finds an ADRP and it relaxes it, it removes the erratum entry from the work list by changing the stub type into none so the stub is ignored. The entry is not actually removed as removal is a more expensive operation and we have already allocated the memory anyway. The clearing is done for IE->LE and GD->LE relaxations, and a testcase is added for the IE case. The GD case I believe to be impossible to get together with the erratum sequence due to the required BL which would break the sequence. However to cover all basis I have added the guard there as well. build on native hardware and regtested on aarch64-none-elf, aarch64-none-elf (32 bit host), aarch64-none-linux-gnu, aarch64-none-linux-gnu (32 bit host) Cross-compiled and regtested on aarch64-none-linux-gnu, aarch64_be-none-linux-gnu Testcase in PR23940 tested and works as expected now and benchmarks ran on A53 showing no regressions and no issues. bfd/ChangeLog: PR ld/23904 * elfnn-aarch64.c (_bfd_aarch64_adrp_p): Use existing constants.

2018-11-01Fix ld action in run_dump_testThomas Preud'homme2-17/+5
run_dump_test proposes an ld action but when trying to make use of it in a gas test it gave me some Tcl error. It turns out that it references the check_shared_lib_support procedure and ld_elf_shared_opt variable both only available in ld-lib.exp. I've thus moved the procedure in binutils-common.exp and defined the variable needed in the various default.exp of testsuite that seem to be using run_dump_test. Since check_shared_lib_support itself references the ld variable not defined in binutils-common I've defined it from LD in run_dump_test and fixed LD and LDFLAGS to be defined as expected by run_dump_test in the various default.exp of testsuite using run_dump_test. 2018-11-01 Thomas Preud'homme <thomas.preudhomme@linaro.org> binutils/ * testsuite/config/default.exp: Define LD, LDFLAGS and ld_elf_shared_opt. * testsuite/lib/binutils-common.exp (check_shared_lib_support): Moved from ld-lib.exp.

For ld -r, we generally set the VMA of sections to zero. This is done to make the output of ld -r most similar to that output by the assembler, which generally has sections starting at VMA zero. In some cases that covers for backend bugs which would mis-handle relocatable object files with non-zero section VMAs. This patch fixes a few sections that didn't have zero VMAs for ld -r. A missing zero on .note.gnu.build-id and .eh_frame_hdr doesn't matter much since these are linker generated symbols only output on final link, but it's good to be consistent. * Makefile.am (ei386beos.c, ei386go32.c): Correct dependencies. * Makefile.in: Regenerate. * scripttempl/elf.sc (.note.gnu.build-id, .eh_frame_hdr): Set address with ${RELOCATING-0}. * scripttempl/arclinux.sc: Likewise. * scripttempl/armbpabi.sc: Likewise. * scripttempl/avr.sc: Likewise. * scripttempl/elf64hppa.sc: Likewise. * scripttempl/elf_chaos.sc: Likewise. * scripttempl/elfarc.sc: Likewise. * scripttempl/elfxtensa.sc: Likewise. * scripttempl/mep.sc: Likewise. * scripttempl/nds32elf.sc: Likewise. * scripttempl/pru.sc: Likewise. * scripttempl/elf32msp430.sc: Likewise, and for other sections. * scripttempl/epiphany_4x4.sc: Similarly.

2018-10-08Separate header PT_LOAD for -z separate-codeAlan Modra12-20/+19
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. Reorganize code handling program headers. Generate a mapping without sections just for file and program headers when -z separate-code would indicate they should be on a different page to the first section. ld/ * ldexp.c (fold_name <SIZEOF_HEADERS>): Set link_info.load_phdrs. * testsuite/ld-elf/loadaddr1.d: Pass -z noseparate-code. * testsuite/ld-elf/loadaddr2.d: Likewise. * testsuite/ld-i386/vxworks2.sd: Adjust expected output. * testsuite/ld-powerpc/vxworks2.sd: Likewise. * testsuite/ld-elf/overlay.d: Remove spu xfail. * testsuite/ld-spu/ovl.lnk: Don't use SIZEOF_HEADERS. * testsuite/ld-tic6x/dsbt-be.ld: Likewise. * testsuite/ld-tic6x/dsbt-inrange.ld: Likewise. * testsuite/ld-tic6x/dsbt-overflow.ld: Likewise. * testsuite/ld-tic6x/dsbt.ld: Likewise.
