What is the difference between instructions like addi and e_addi OR lwz and se_lwz? I am using previously developed assembly/C code and trying to make a project and build it using S32 design studio. I get errors on instructions like addi, and if I change it to e_addi, it will show no error. I am unsure what the e_ is for. Are there compiler options to change? Project settings? Does anyone know if there is any documentation for this? I have been unsuccessful at finding anything.
