One great example of the benefits of pseudo instructions is the LI and LA instructions. Because all RISC-V instructions must be 32-bit wide, they cannot contain a full 32-bit address.

Op codes in blue are SIC/XE only instructions Op codes in red are not implemented by the simulator. Notes: P=privileged, C=CC set (,=,>), F=floating point See Appendix A of System Software by Beck for information on instruction formats and addressing modes. WebAlthough it has only one instruction, SIC can imitate many of the operations of more complex instruction sets by using clever sequences of sbn instructions. For example, here is a program to copy a number from location a to location b: start:sbn temp,temp,.+1 # Sets temp to zero sbn temp,a,.+1 # Sets temp to -a sbn b,b,.+1 # Sets b to zero don\u0027t toy with me miss nagatoro spoilers
