Ayke van Laethem d606315515 builder: try to determine stack size information at compile time For now, this is just an extra flag that can be used to print stack frame information, but this is intended to provide a way to determine stack sizes for goroutines at compile time in many cases. Stack sizes are often somewhere around 350 bytes so are in fact not all that big usually. Once this can be determined at compile time in many cases, it is possible to use this information when available and as a result increase the fallback stack size if the size cannot be determined at compile time. This should reduce stack overflows while at the same time reducing RAM consumption in many cases. Interesting output for testdata/channel.go: function stack usage (in bytes) Reset_Handler 332 .Lcommand-line-arguments.fastreceiver 220 .Lcommand-line-arguments.fastsender 192 .Lcommand-line-arguments.iterator 192 .Lcommand-line-arguments.main$1 184 .Lcommand-line-arguments.main$2 200 .Lcommand-line-arguments.main$3 200 .Lcommand-line-arguments.main$4 328 .Lcommand-line-arguments.receive 176 .Lcommand-line-arguments.selectDeadlock 72 .Lcommand-line-arguments.selectNoOp 72 .Lcommand-line-arguments.send 184 .Lcommand-line-arguments.sendComplex 192 .Lcommand-line-arguments.sender 192 .Lruntime.run$1 548 This shows that the stack size (if these numbers are correct) can in fact be determined automatically in many cases, especially for small goroutines. One of the great things about Go is lightweight goroutines, and reducing stack sizes is very important to make goroutines lightweight on microcontrollers.		4 years ago
