Carl Shapiro f056daf075 cmd/5g, cmd/5l, cmd/6g, cmd/6l, cmd/8g, cmd/8l, cmd/gc, runtime: generate pointer maps by liveness analysis ... This change allows the garbage collector to examine stack slots that are determined as live and containing a pointer value by the garbage collector. This results in a mean reduction of 65% in the number of stack slots scanned during an invocation of "GOGC=1 all.bash". Unfortunately, this does not yet allow garbage collection to be precise for the stack slots computed as live. Pointers confound the determination of what definitions reach a given instruction. In general, this problem is not solvable without runtime cost but some advanced cooperation from the compiler might mitigate common cases.
