[Brandon Wu via Phabricator via cfe-commits]

4vtomat added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVCallingConv.td:52
 // Same as CSR_Interrupt, but including all 64-bit FP registers.
 def CSR_XLEN_F64_Interrupt: CalleeSavedRegs<(add CSR_Interrupt,
                                              (sequence "F%u_D", 0, 31))>;

Yeah, we should also handle these in interrupt function, but seems it's not related to this patch. Am I right? @kito-cheng
