Russ Cox e431398e09 undo CL 6938073 / 1542912cf09d ... remove zerostack compiler experiment; will do at link time instead ««« original CL description cmd/gc: add GOEXPERIMENT=zerostack to clear stack on function entry This is expensive but it might be useful in cases where people are suffering from false positives during garbage collection and are willing to trade the CPU time for getting rid of the false positives. On the other hand it only eliminates false positives caused by other function calls, not false positives caused by dead temporaries stored in the current function call. The 5g/6g/8g changes were pulled out of the history, from the last time we needed to do this (to work around a goto bug). The code in go.h, lex.c, pgen.c is new but tiny.
