Subject: [PATCH v2] gas/NEWS, ld/NEWS: Announce LoongArch changes in 2.42
Date: Tue, 23 Jan 2024 19:12:16 +0800 [thread overview]
Message-ID: <20240123111325.36166-1-xry111@xry111.site> (raw)
In-Reply-To: <0999dbf2-c656-4b5e-8f6c-5424a21a3fc6@redhat.com>
The change is self-explained, no more commit message :).

v1 -> v2:
- Do not falsely claim la.tls.le supported relax.
- Do not mention 3-operand .align directive support because it only
supports an empty 2nd operand with a warning as at now.

@@ -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:
