65,338,263 | go | cmd/compile: inline function calls that return a closure | ERROR: type should be string, got "https://go-review.googlesource.com/#/c/8200/ added a benchmark to the strings package that shows strings.Trim and its variants allocate memory. The allocation is caused by the call to makeCutsetFunc <a href=\"https://github.com/golang/go/blob/master/src/strings/strings.go#L625\">here</a>. Inlining this call removes the allocation and provides a nice performance boost to Trim. You can see the effect on the benchmark using Go Tip (commit 6262192cd0fb98d6bb80752de70ae33fc10dc33e) below:\n\n```\nbenchmark old ns/op new ns/op delta\nBenchmarkTrim 3204 2323 -27.50%\n\nbenchmark old allocs new allocs delta\nBenchmarkTrim 11 0 -100.00%\n\nbenchmark old bytes new bytes delta\nBenchmarkTrim 352 0 -100.00%\n```\n\nmakeCutsetFunc is a pretty simple function (all it does is return a closure), and it was pointed out in review that it might be nice to inline functions like it in the compiler rather than changing strings.Trim explicitly. \n" | Performance,NeedsInvestigation,compiler/runtime | low | Major |
