   4 Subject: [PATCH] LoongArch: Modify MUSL_DYNAMIC_LINKER.
   5
   6 Use no suffix at all in the musl dynamic linker name for hard
   7 float ABI. Use -sf and -sp suffixes in musl dynamic linker name
   8 for soft float and single precision ABIs. The following table
   9 outlines the musl interpreter names for the LoongArch64 ABI names.
  10
  11 musl interpreter            | LoongArch64 ABI
  12 --------------------------- | -----------------
  13 ld-musl-loongarch64.so.1    | loongarch64-lp64d
  14 ld-musl-loongarch64-sp.so.1 | loongarch64-lp64f
  15 ld-musl-loongarch64-sf.so.1 | loongarch64-lp64s
