cmd/compile: port callnew to ssa conversion This is part of a general effort to shrink walk. In an ideal world, we'd have an SSA op for allocation, but we don't yet have a good mechanism for introducing function calling during SSA compilation. In the meantime, SSA conversion is a better place for it. This also makes it easier to introduce new optimizations; instead of doing the typecheck walk dance, we can simply write what we want the backend to do. I introduced a new opcode in this change because: (a) It avoids a class of bugs involving correctly detecting whether this ONEW is a "before walk" ONEW or an "after walk" ONEW. It also means that using ONEW or ONEWOBJ in the wrong context will generally result in a faster failure. (b) Opcodes are cheap. (c) It provides a better place to put documentation. This change also is also marginally more performant: name old alloc/op new alloc/op delta Template 39.1MB ± 0% 39.0MB ± 0% -0.14% (p=0.008 n=5+5) Unicode 28.4MB ± 0% 28.4MB ± 0% ~ (p=0.421 n=5+5) GoTypes 132MB ± 0% 132MB ± 0% -0.23% (p=0.008 n=5+5) Compiler 608MB ± 0% 607MB ± 0% -0.25% (p=0.008 n=5+5) SSA 2.04GB ± 0% 2.04GB ± 0% -0.01% (p=0.008 n=5+5) Flate 24.4MB ± 0% 24.3MB ± 0% -0.13% (p=0.008 n=5+5) GoParser 29.3MB ± 0% 29.1MB ± 0% -0.54% (p=0.008 n=5+5) Reflect 84.8MB ± 0% 84.7MB ± 0% -0.21% (p=0.008 n=5+5) Tar 36.7MB ± 0% 36.6MB ± 0% -0.10% (p=0.008 n=5+5) XML 48.7MB ± 0% 48.6MB ± 0% -0.24% (p=0.008 n=5+5) [Geo mean] 85.0MB 84.8MB -0.19% name old allocs/op new allocs/op delta Template 383k ± 0% 382k ± 0% -0.26% (p=0.008 n=5+5) Unicode 341k ± 0% 341k ± 0% ~ (p=0.579 n=5+5) GoTypes 1.37M ± 0% 1.36M ± 0% -0.39% (p=0.008 n=5+5) Compiler 5.59M ± 0% 5.56M ± 0% -0.49% (p=0.008 n=5+5) SSA 16.9M ± 0% 16.9M ± 0% -0.03% (p=0.008 n=5+5) Flate 238k ± 0% 238k ± 0% -0.23% (p=0.008 n=5+5) GoParser 306k ± 0% 303k ± 0% -0.93% (p=0.008 n=5+5) Reflect 990k ± 0% 987k ± 0% -0.33% (p=0.008 n=5+5) Tar 356k ± 0% 355k ± 0% -0.20% (p=0.008 n=5+5) XML 444k ± 0% 442k ± 0% -0.45% (p=0.008 n=5+5) [Geo mean] 848k 845k -0.33% Change-Id: I2c36003a7cbf71b53857b7de734852b698f49310 Reviewed-on: https://go-review.googlesource.com/c/go/+/167957 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Matthew Dempsky <mdempsky@google.com>
