Last CL we separated mallocgc into several specialized paths. Let's split up heapSetType too. This will make the specialized heapSetType functions inlineable and cut out some branches as well as a function call. Microbenchmark results at this point in the stack: │ before.out │ after-5.out │ │ sec/op │ sec/op vs base │ Malloc8-4 13.52n ± 3% 12.15n ± 2% -10.13% (p=0.002 n=6) Malloc16-4 21.49n ± 2% 18.32n ± 4% -14.75% (p=0.002 n=6) MallocTypeInfo8-4 27.12n ± 1% 18.64n ± 2% -31.30% (p=0.002 n=6) MallocTypeInfo16-4 28.71n ± 3% 21.63n ± 5% -24.65% (p=0.002 n=6) geomean 21.81n 17.31n -20.64% Change-Id: I5de9ac5089b9eb49bf563af2a74e6dc564420e05 Reviewed-on: https://go-review.googlesource.com/c/go/+/614795 Auto-Submit: Michael Knyszek <mknyszek@google.com> Reviewed-by: Keith Randall <khr@golang.org> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com> Reviewed-by: Keith Randall <khr@google.com> |
