Hi all, I'm very instresting in LLVM, and trying to port a dsp target on LLVM now. I found that, the Greddy Register Allocator will generate a reload instrucion just between the function call and ADJCALLSTACKUP instruction. If the reload instruction is transfered to be a load instruction finally, which uses the SP register as an operand, and the target uses the ADJCALLSTACKUP instruction to
