2011-01-19mn10300: Emit retf instructionRichard Henderson4-49/+69
Now that we properly track the life of MDR, we can emit the RETF instruction if MDR has not been modified. This insn is 3-4 cycles faster since the return address is already loaded. From-SVN: r169013
2011-01-19mn10300: tidy pic address loadingRichard Henderson5-218/+118
There's little reason to greatly complicate things by splitting the pic_load patterns and using complex rtl to make it work out. Instead, use the %= marker to generate unique numbers and emit the entire load_pic sequence at once. At the same time, collect all references to outgoing_args_size into mn10300_frame_size, and all computations of register save area size into mn10300_initial_offset. From-SVN: r169012
