...compiler-rt recently, and I've got a problem when adding soft float routine for rv32, RISC-V ABI required 128 bits bits for long double, but it's implemented by int128_t, however rv32 don't support __int128_t. Of cause, it not hard thing to support __int128_t by overriding TargetInfo::hasInt128Type for LLVM, but its will cause some ABI incompatible with GCC, because GCC don't support __int128_t for 32 bits target. So I guess I've few option here: 1. Implement 128 bits soft-float with int64_t. 2. Add an option to force enable int128_t support during building compiler-rt for rv32. An...
