LoongArch

+
    +
  • Support for the following + + -march parameters has been added: +
      +
    • la64v1.0
      • +
    • la64v1.1
      • +
    • la664
      • +
    + It is now recommended to use -march=la64v1.0 as the only + compiler option to describe the target ISA when building binaries for + distribution. For more information on LoongArch ISA versions, see + + Toolchain Conventions of the LoongArch™ Architecture. +
    • +
  • Support for the following + + -mtune parameters has been added: +
      +
    • generic
      • +
    • la664
      • +
    +
    • +
  • New ISA Extension +
      +
    • LSX (Loongson SIMD Extension): Support 128-bit vector instructions + and the intrinsics. +
      • +
    • LASX (Loongson Advanced SIMD Extension): Support 256-bit vector + instructions and the intrinsics. +
      • +
    • FRECIPE: Support frecipe.{s/d} and + frsqrte.{s/d} instructions and the intrinsics. +
      • +
    • DIV32: Support div.w[u] and mod.w[u] + instructions with inputs not sign-extended. +
      • +
    • LAM_BH: Support am{swap/add}[_db].{b/h} instructions. +
      • +
    • LAMCAS: Support amcas[_db].{b/h/w/d} instructions. +
      • +
    +
    • +
  • New Built-in Macros +
      +
    • __loongarch_arch: Target ISA preset as specified by + -march=. For example, compiling with + -march=la64v1.0, the value of __loongarch_arch + is "la64v1.0". +
      • +
    • __loongarch_tune: Processor model as specified by + -mtune or its default value. +
      • +
    • __loongarch_{simd,sx,asx}: These macros are not defined, + or defined as 1. +
      • +
    • __loongarch_simd_width: The maximum SIMD bit-width + enabled by the compiler. (128 for lsx, and 256 for lasx). +
      • +
    • __loongarch_frecipe: It's defined to 1 or undefined. +
      • +
    • __loongarch_div32: It's defined to 1 or undefined.
      • +
    • __loongarch_lam_bh: It's defined to 1 or undefined.
      • +
    • __loongarch_lamcas: It's defined to 1 or undefined.
      • +
    • __loongarch_ld_seq_sa: It's defined to 1 or undefined. +
      • +
    • __loongarch_version_major: + The minimally required LoongArch ISA version (major) to run the + compiled program, defined to 1 or undefined (iff no such version is + known to the compiler). +
      • +
    • __loongarch_version_minor: + The minimally required LoongArch ISA version (minor) to run the + compiled program, defined to 0 1 or undefined (iff + __loongarch_version_major is undefined). +
      • +
    • __FLOAT128_TYPE: It's defined to 1.
      • +
    +
    • +
  • New Intrinsics + +
    • +
  • New Compiler Option + +
    • +
  • Support for Ada and D.
    • +
  • Support for libffi.
    • +
  • Enable -free by default at -O2 or higher.
    • +
  • Enable -fsched-pressure by default at -O1 or + higher. +
    • +
  • Support the extreme code model using macro instructions + (under -mno-explicit-relocs).
    • +
  • Support call36.
    • +
  • Optimizing built-in functions for memory-model-aware atomic operations + using hierarchical dbar instructions.
    • +
  • TLS descriptors support. It is not enabled by default, and can be enabled + with + -mtls-dialect=desc. The default behavior can be + configured with --with-tls=[trad|desc].
