[go-nuts] maptype questions

for this code: m := make(map[int]int, 9) I think the compiler creates a maptype that is stored at type.*+60480(SB) that it uses for the call to runtime.makemap: m := make(map[int]int, 9) 0x10d0b81 488d05f8ec LEAQ type.*+60480(SB), AX 0x10d0b88 48890424 MOVQ AX, 0(SP) 0x10d0b8c

[go-nuts] [runtime] gostring question

I'm a C programmer so maybe this is a dumb question but, why does this code in runtime/gostring.go allocate (rawstring) then copy data (memmove) instead of just making the stringStruct.str point at the incoming data? i.e. copy the pointer instead of allocating+copying data. func gostring(p
