Hi, I have a custom lowering operation on ISD::BITCAST for the PowerPC/SPE target, to convert 'f64 bitcast (i64 build_pair i32, i32)' into a 'f64 BUILD_SPE64 i32, i32' node, which can be seen at https://reviews.llvm.org/D54583. However, when building compiler-rt's lib/builtins/divdc3.c an assertion is triggered that BUILD_PAIR is not legal on line 24. There should be no bitcast(buildpair) anywhere in the generation, as it should all be lowered. However, this is not the case when lowering to a libcall it seems. The relevant debug output, is here: Creating new node: t118: i64...
