SUSE-SU-2020:3552-1

This update for binutils fixes the following issues:

binutils was updated to version 2.35.1 (jsc#ECO-2373)

Additional branch fixes applied on top of 2.35.1:

• Fixes PR26520, aka [bsc#1179036], a problem in addr2line with certain DWARF variable descriptions.
• Also fixes PR26711, PR26656, PR26655, PR26929, PR26808, PR25878, PR26740, PR26778, PR26763, PR26685, PR26699, PR26902, PR26869, PR26711
• The above includes fixes for dwo files produced by modern dwp, fixing several problems in the DWARF reader.

Update to binutils 2.35.1 and rebased branch diff:

• This is a point release over the previous 2.35 version, containing bug fixes, and as an exception to the usual rule, one new feature. The new feature is the support for a new directive in the assembler: '.nop'. This directive creates a single no-op instruction in whatever encoding is correct for the target architecture. Unlike the .space or .fill this is a real instruction, and it does affect the generation of DWARF line number tables, should they be enabled.

Update to binutils 2.35:

• The assembler can now produce DWARF-5 format line number tables.
• Readelf now has a 'lint' mode to enable extra checks of the files it is processing.
• Readelf will now display '[...]' when it has to truncate a symbol name.
  The old behaviour - of displaying as many characters as possible, up to the 80 column limit - can be restored by the use of the --silent-truncation option.

• The linker can now produce a dependency file listing the inputs that it has processed, much like the -M -MP option supported by the compiler.

• fix DT_NEEDED order with -flto [bsc#1163744]

Update to binutils 2.34:

• The disassembler (objdump --disassemble) now has an option to generate ascii art thats show the arcs between that start and end points of control flow instructions.
• The binutils tools now have support for debuginfod. Debuginfod is a HTTP service for distributing ELF/DWARF debugging information as well as source code. The tools can now connect to debuginfod servers in order to download debug information about the files that they are processing.

• The assembler and linker now support the generation of ELF format files for the Z80 architecture.

• Add new subpackages for libctf and libctf-nobfd.

• Disable LTO due to bsc#1163333.

• Includes fixes for these CVEs: bsc#1153768 aka CVE-2019-17451 aka PR25070 bsc#1153770 aka CVE-2019-17450 aka PR25078

• fix various build fails on aarch64 (PR25210, bsc#1157755).

Update to binutils 2.33.1:

• Adds support for the Arm Scalable Vector Extension version 2 (SVE2) instructions, the Arm Transactional Memory Extension (TME) instructions and the Armv8.1-M Mainline and M-profile Vector Extension (MVE) instructions.
• Adds support for the Arm Cortex-A76AE, Cortex-A77 and Cortex-M35P processors and the AArch64 Cortex-A34, Cortex-A65, Cortex-A65AE, Cortex-A76AE, and Cortex-A77 processors.
• Adds a .float16 directive for both Arm and AArch64 to allow encoding of 16-bit floating point literals.
• For MIPS, Add -m[no-]fix-loongson3-llsc option to fix (or not) Loongson3 LLSC Errata. Add a --enable-mips-fix-loongson3-llsc=[yes|no] configure time option to set the default behavior. Set the default if the configure option is not used to 'no'.
• The Cortex-A53 Erratum 843419 workaround now supports a choice of which workaround to use. The option --fix-cortex-a53-843419 now takes an optional argument --fix-cortex-a53-843419[=full|adr|adrp] which can be used to force a particular workaround to be used. See --help for AArch64 for more details.
• Add support for GNUPROPERTYAARCH64FEATURE1BTI and GNUPROPERTYAARCH64FEATURE1PAC in ELF GNU program properties in the AArch64 ELF linker.
• Add -z force-bti for AArch64 to enable GNUPROPERTYAARCH64FEATURE1BTI on output while warning about missing GNUPROPERTYAARCH64FEATURE1BTI on inputs and use PLTs protected with BTI.
• Add -z pac-plt for AArch64 to pick PAC enabled PLTs.
• Add --source-comment[=<txt>] option to objdump which if present, provides a prefix to source code lines displayed in a disassembly.
• Add --set-section-alignment <section-name>=<power-of-2-align> option to objcopy to allow the changing of section alignments.
• Add --verilog-data-width option to objcopy for verilog targets to control width of data elements in verilog hex format.
• The separate debug info file options of readelf (--debug-dump=links and --debug-dump=follow) and objdump (--dwarf=links and --dwarf=follow-links) will now display and/or follow multiple links if more than one are present in a file. (This usually happens when gcc's -gsplit-dwarf option is used). In addition objdump's --dwarf=follow-links now also affects its other display options, so that for example, when combined with --syms it will cause the symbol tables in any linked debug info files to also be displayed. In addition when combined with --disassemble the --dwarf= follow-links option will ensure that any symbol tables in the linked files are read and used when disassembling code in the main file.
• Add support for dumping types encoded in the Compact Type Format to objdump and readelf.

• Includes fixes for these CVEs: bsc#1126826 aka CVE-2019-9077 aka PR1126826 bsc#1126829 aka CVE-2019-9075 aka PR1126829 bsc#1126831 aka CVE-2019-9074 aka PR24235 bsc#1140126 aka CVE-2019-12972 aka PR23405 bsc#1143609 aka CVE-2019-14444 aka PR24829 bsc#1142649 aka CVE-2019-14250 aka PR90924
