Where possible generate calls to runtime makemap with int hint argument during compile time instead of makemap with int64 hint argument. This eliminates converting the hint argument for calls to makemap with int64 hint argument for platforms where int64 values do not fit into an argument of type int. A similar optimization for makeslice was introduced in CL golang.org/cl/27851. 386: name old time/op new time/op delta NewEmptyMap 53.5ns ± 5% 41.9ns ± 5% -21.56% (p=0.000 n=10+10) NewSmallMap 182ns ± 1% 165ns ± 1% -8.92% (p=0.000 n=10+10) Change-Id: Ibd2b4c57b36f171b173bf7a0602b3a59771e6e44 Reviewed-on: https://go-review.googlesource.com/55142Reviewed-by:
