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. |
