Changelog:
GAS
Changes in 2.32:
* Add -mvexwig=[0|1] option to x86 assembler to control encoding of
VEX.W-ignored (WIG) VEX instructions.
* Add -mx86-used-note=[yes|no] option to generate (or not) x86 GNU property
notes. Add a --enable-x86-used-note configure time option to set the
default behavior. Set the default if the configure option is not used
to "no".
* Add support for the MIPS Loongson EXTensions R2 (EXT2) instructions.
* Add support for the MIPS Loongson EXTensions (EXT) instructions.
* Add support for the MIPS Loongson Content Address Memory (CAM) ASE.
* Add support for the C-SKY processor series.
* Add support for the MIPS Loongson MultiMedia extensions Instructions (MMI)
ASE.
LD
Changes in 2.32:
* Report property change in linker map file when merging GNU properties.
* Add support for the C-SKY processor series.
* -t now doesn't report members within archives, unless -t is given twice.
A single -t is now more useful when generating a list of files that should be
packaged for a linker bug report. For example:
gcc hello.c -save-temps -Wl,-t | xargs realpath | sort | uniq > files
tar cJf test.tar.xz `cat files`
BINUTILS
Changes in 2.32:
* The addr2line, c++filt, nm and objdump tools now have a limit on the
maximum amount of recursion that is allowed whilst demangling strings.
The value for this limit is defined by the DEMANGLE_RECRUSE_LIMIT
constant declared in the include/demangle.h header file. At the time
of writing this constant has the value of 2048.
The --no-recurse-limit option can be used to remove the limit, restoring
the behaviour of earlier versions of these tools. This may be needed in
order to dmangle truly complicated names, but it also leaves the tools
vulnerable to stack exhaustion from maliciously constructed mangled names.
* Objdump's --disassemble option can now take a parameter, specifying the
starting symbol for disassembly. Disassembly will continue from this
symbol up to the next symbol or the end of the function.
* The MIPS port now supports the Loongson 2K1000 processor which implements
the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE, Loongson-ext ASE,
Loongson-ext2 ASE and MSA ASE instructions. Add -march=gs264e option for
Loongson 2K1000 processor.
* The MIPS port now supports the Loongson 3A2000/3A3000 processor which
implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE,
Loongson-ext ASE and Loongson-ext2 ASE instructions. Add -march=gs464e
option for Loongson 3A2000/3A3000 processor.
* The MIPS port now supports the Loongson 3A1000 processor, aka Loongson3a,
which implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE
and Loongson-ext ASE instructions. Add -march=gs464 option for Loongson
3A1000 processor, The -march=loongson3a is an alias of -march=gs464 for
compatibility.
