@ -66,6 +66,33 @@ Changes in 2.42:
* The BPF assembler now allows using both hash (#) and double slash (//) to
begin line comments.
* Add support for LoongArch v1.10 new instructions: estimated reciprocal
instructions, sub-word atomic instructions, atomic CAS instructions,
16-byte store-conditional instruction, load-linked instructions with
acquire semantics, and store-conditional instructions with release
semantics.
* The %call36 relocation operator, along with the pseudo-instructions
call36 and tail36, are now usable with the LoongArch "medium" code
model, allowing text sections up to 128 GiB.
* TLS descriptors (TLSDESC) are now supported on LoongArch. This includes
the following new relocation operators: %desc_pc_hi20, %desc_pc_lo12,
%desc_ld, and %desc_call, and the la.tls.desc pseudo-instruction.
* TLS LE relaxation is now supported on LoongArch. New relocation
operators %le_hi20_r, %le_lo12r, and %le_add_r are now available.
* Add support for LoongArch branch relaxation: a conditional branch with
destination out of its immediate operand range, but still within
a "b"'s range, is now assembled as an inverted branch and a "b". This
works around the unreliable branch offset estimation of the compiler
when .align directive is encoded into a long NOP sequence with an
R_LARCH_RELAX by the assembler.
* Symbol or label names in LoongArch assembly can now be spelled with
double-quotes.
Changes in 2.41:
* Add support for the KVX instruction set.

--enable-error-rwx-segments=[yes|no] configure options to set the default for
converting warnings into errors.
* On LoongArch, various linker relaxation bugs are fixed; the most notable
of which is BZ 30944 (incorrect .balign semantics).
* On LoongArch, the LoongArch ABI v2.30 (LoongArch ELF psABI v20231219) is
now implemented. This includes new relocation types, and changed
semantics for PC-relative relocations handling the higher half of 64-bit
offsets.
* On LoongArch, link-time TLS optimization and TLS relaxation are now
supported.
Changes in 2.41:
* The linker now accepts a command line option of --remap-inputs
