Hello, The current code in PPCTargetLowering::LowerFormalArguments_SVR4 contains a FIXME over the code which saves the live floating-point registers to the stack. The FIXME states that this should only be done if CR bit 6 is set. I've been told that the lack of this check is preventing clang/LLVM from compiling a functional FreeBSD kernel on PPC. Is is possible to...
