[PATCH] D92067: [PowerPC] Promote the i1 to i64 for SINT_TO_FP/FP_TO_SINT

[Qiu Chaofan via Phabricator via llvm-commits]

qiucf added a comment.

After applying this patch, I enumerated signed/unsigned conversion between `i1~i128` and `f32/f64/f128/ppcf128`, only `ppcf128-i1` still crashes:

  define i1 @pq_s1(ppc_fp128 %a) {
    %b = fptosi ppc_fp128 %a to i1
    ret i1 %b
  }
  
  define i1 @pq_u1(ppc_fp128 %a) {
    %b = fptoui ppc_fp128 %a to i1
    ret i1 %b
  }



  Assertion failed: (LC != RTLIB::UNKNOWN_LIBCALL && "Unsupported FP_TO_SINT!"), function ExpandFloatOp_FP_TO_SINT, file llvm-project/llvm/lib/CodeGen/SelectionDAG/LegalizeFloatTypes.cpp

Similar promotion can also fix this?
