Prior to this CL, autotmps were global to a package. They also shared numbering with static variables. Switch autotmp numbering to be per-function instead, and do implicit numbering based on len(Func.Dcl). This eliminates a dependency on a global variable from the backend without adding to the Func struct. While we're here, move statuniqgen closer to its sole remaining user. This actually improves compiler performance, because the autotmp_* names can now be reused across functions. name old alloc/op new alloc/op delta Template 40.6MB ± 0% 40.1MB ± 0% -1.38% (p=0.000 n=10+10) Unicode 29.9MB ± 0% 29.9MB ± 0% ~ (p=0.912 n=10+10) GoTypes 116MB ± 0% 114MB ± 0% -1.53% (p=0.000 n=10+10) SSA 865MB ± 0% 856MB ± 0% -1.04% (p=0.000 n=10+10) Flate 25.8MB ± 0% 25.4MB ± 0% -1.36% (p=0.000 n=10+10) GoParser 32.2MB ± 0% 32.0MB ± 0% -0.72% (p=0.000 n=10+10) Reflect 80.3MB ± 0% 79.0MB ± 0% -1.65% (p=0.000 n=9+10) Tar 27.0MB ± 0% 26.7MB ± 0% -0.86% (p=0.000 n=10+9) XML 42.8MB ± 0% 42.4MB ± 0% -0.95% (p=0.000 n=10+10) name old allocs/op new allocs/op delta Template 398k ± 1% 396k ± 1% -0.59% (p=0.002 n=10+10) Unicode 321k ± 1% 321k ± 0% ~ (p=0.912 n=10+10) GoTypes 1.17M ± 0% 1.16M ± 0% -0.77% (p=0.000 n=10+10) SSA 7.65M ± 0% 7.62M ± 0% -0.40% (p=0.000 n=10+10) Flate 240k ± 1% 238k ± 1% -0.56% (p=0.001 n=10+10) GoParser 323k ± 1% 320k ± 1% -0.65% (p=0.002 n=10+10) Reflect 1.01M ± 0% 1.00M ± 0% -0.37% (p=0.001 n=9+10) Tar 256k ± 1% 255k ± 0% ~ (p=0.101 n=10+8) XML 400k ± 1% 398k ± 1% ~ (p=0.063 n=10+10) Change-Id: I3c23ca98129137d373106990b1a3e1507bbe0cc3 Reviewed-on: https://go-review.googlesource.com/38729 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Matthew Dempsky <mdempsky@google.com> |
