* The AArch64 port now supports showing disassembly notes which are emitted
when inconsistencies are found with the instruction that may result in the
instruction being invalid. These can be turned on with the option -M notes
to objdump.
* The AArch64 port now emits warnings when a combination of an instruction and
a named register could be invalid.
* Added O modifier to ar to display member offsets inside an archive
* The ADR and ADRL pseudo-instructions supported by the ARM assembler
now only set the bottom bit of the address of thumb function symbols
if the -mthumb-interwork command line option is active.
* Add --generate-missing-build-notes=[yes|no] option to create (or not) GNU
Build Attribute notes if none are present in the input sources. Add a
--enable-generate-build-notes=[yes|no] configure time option to set the
default behaviour. Set the default if the configure option is not used
to "no".
* Remove -mold-gcc command-line option for x86 targets.
* Add -O[2|s] command-line options to x86 assembler to enable alternate
shorter instruction encoding.
* Add support for .nops directive. It is currently supported only for
x86 targets.
* Speed up direct linking with DLLs for Cygwin and Mingw targets.
* Add a configure option --enable-separate-code to decide whether
-z separate-code should be enabled in ELF linker by default. Default
to yes for Linux/x86 targets. Note that -z separate-code can increase
disk and memory size.
* Includes riscv-relax-size.patch, riscv-relax-relocatable.patch,
riscv-relax-versioned-hidden.patch and riscv-wrap-relax.patch
- Refresh enable-targets-gold.diff.
OBS-URL: https://build.opensuse.org/package/show/devel:gcc/binutils?expand=0&rev=279
- Update to binutils 2.30
* Add --debug-dump=links option to readelf and --dwarf=links option to objdump
which displays the contents of any .gnu_debuglink or .gnu_debugaltlink
sections.
Add a --debug-dump=follow-links option to readelf and a --dwarf=follow-links
option to objdump which causes indirect links into separate debug info files
to be followed when dumping other DWARF sections.
* Add support for loaction views in DWARF debug line information.
* Add -z separate-code to generate separate code PT_LOAD segment.
* Add "-z undefs" command line option as the inverse of the "-z defs" option.
* Add -z globalaudit command line option to force audit libraries to be run
for every dynamic object loaded by an executable - provided that the loader
supports this functionality.
* Tighten linker script grammar around file name specifiers to prevent the use
of SORT_BY_ALIGNMENT and SORT_BY_INIT_PRIORITY on filenames. These would
previously be accepted but had no effect.
* The EXCLUDE_FILE directive can now be placed within any SORT_* directive
within input section lists.

* The MIPS port now supports microMIPS eXtended Physical Addressing (XPA)
instructions for assembly and disassembly.
* The MIPS port now supports the microMIPS Release 5 ISA for assembly and
disassembly.
* The MIPS port now supports the Imagination interAptiv MR2 processor,
which implements the MIPS32r3 ISA, the MIPS16e2 ASE as well as a couple
of implementation-specific regular MIPS and MIPS16e2 ASE instructions.
* The SPARC port now supports the SPARC M8 processor, which implements the
Oracle SPARC Architecture 2017.
* The MIPS port now supports the MIPS16e2 ASE for assembly and disassembly.
* Add support for ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX.
* Add support for the wasm32 ELF conversion of the WebAssembly file format.
* Add --inlines option to objdump, which extends the --line-numbers option
so that inlined functions will display their nesting information.
* Add --merge-notes options to objcopy to reduce the size of notes in
a binary file by merging and deleting redundant notes.
* Add support for locating separate debug info files using the build-id
method, where the separate file has a name based upon the build-id of
the original file.
GAS
* Add support for ELF SHF_GNU_MBIND.
* Add support for the WebAssembly file format and wasm32 ELF conversion.
* PowerPC gas now checks that the correct register class is used in
instructions. For instance, "addi %f4,%cr3,%r31" warns three times
that the registers are invalid.
* Add support for the Texas Instruments PRU processor.
* Support for the ARMv8-R architecture and Cortex-R52 processor has been
added to the ARM port.

* Add support for locating separate debug info files using the build-id
method, where the separate file has a name based upon the build-id of
the original file.
* This version of binutils fixes a problem with PowerPC VLE 16A and 16D
relocations which were functionally swapped, for example,
R_PPC_VLE_HA16A performed like R_PPC_VLE_HA16D while R_PPC_VLE_HA16D
performed like R_PPC_VLE_HA16A. This could have been fixed by
renumbering relocations, which would keep object files created by an
older version of gas compatible with a newer ld. However, that would
require an ABI update, affecting other assemblers and linkers that
create and process the relocations correctly. It is recommended that
all VLE object files be recompiled, but ld can modify the relocations
if --vle-reloc-fixup is passed to ld. If the new ld command line
option is not used, ld will ld warn on finding relocations inconsistent
with the instructions being relocated.
* The nm program has a new command line option (--with-version-strings)
which will display a symbol's version information, if any, after the
symbol's name.
* The ARC port of objdump now accepts a -M option to specify the extra
instruction class(es) that should be disassembled.
* The --remove-section option for objcopy and strip now accepts section
patterns starting with an exclamation point to indicate a non-matching
section. A non-matching section is removed from the set of sections
matched by an earlier --remove-section pattern.
* The --only-section option for objcopy now accepts section patterns
starting with an exclamation point to indicate a non-matching section.
A non-matching section is removed from the set of sections matched by
an earlier --only-section pattern.
* New --remove-relocations=SECTIONPATTERN option for objcopy and strip.

* Add a configure option, --enable-64-bit-archive, to force use of a
64-bit format when creating an archive symbol index.
* Add --elf-stt-common= option to objcopy for ELF targets to control
whether to convert common symbols to the STT_COMMON type.
GAS:
* Default to --enable-compressed-debug-sections=gas for Linux/x86 targets.
* Add --no-pad-sections to stop the assembler from padding the end of output
sections up to their alignment boundary.
* Support for the ARMv8-M architecture has been added to the ARM port.
Support for the ARMv8-M Security and DSP Extensions has also been added
to the ARM port.
* ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
.extCoreRegister pseudo-ops that allow an user to define custom
instructions, conditional codes, auxiliary and core registers.
* Add a configure option --enable-elf-stt-common to decide whether ELF
assembler should generate common symbols with the STT_COMMON type by
default. Default to no.
* New command line option --elf-stt-common= for ELF targets to control
whether to generate common symbols with the STT_COMMON type.
* Add ability to set section flags and types via numeric values for ELF
based targets.
* Add a configure option --enable-x86-relax-relocations to decide whether
x86 assembler should generate relax relocations by default. Default to
yes, except for x86 Solaris targets older than Solaris 12.
* New command line option -mrelax-relocations= for x86 target to control
whether to generate relax relocations.
* New command line option -mfence-as-lock-add=yes for x86 target to encode
lfence, mfence and sfence as "lock addl $0x0, (%[re]sp)".
