This is a list of possible improvements to the SSA pass of the compiler. Optimizations (better compiled code) ------------------------------------ - Reduce register pressure in scheduler - Make dead store pass inter-block - If there are a lot of MOVQ $0, ..., then load 0 into a register and use the register as the source instead. - Allow large structs to be SSAable (issue 24416) - Allow arrays of length >1 to be SSAable - If strings are being passed around without being interpreted (ptr and len fields being accessed) pass them in xmm registers? Same for interfaces? - any pointer generated by unsafe arithmetic must be non-nil? (Of course that may not be true in general, but it is for all uses in the runtime, and we can play games with unsafe.) Optimizations (better compiler) ------------------------------- - Handle signed division overflow and sign extension earlier Regalloc -------- - Make liveness analysis non-quadratic
