@@ -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. |
