Cherry Zhang	401d7e5a24	[dev.regabi] cmd/compile: reserve X15 as zero register on AMD64 ... In ABIInternal, reserve X15 as constant zero, and use it to zero memory. (Maybe there can be more use of it?) The register is zeroed when transition to ABIInternal from ABI0. Caveat: using X15 generates longer instructions than using X0. Maybe we want to use X0?

Josh Bleecher Snyder	8114242359	cmd/compile, runtime: use more registers for amd64 write barrier calls ... The compiler-inserted write barrier calls use a special ABI for speed and to minimize the binary size impact. runtime.gcWriteBarrier takes its args in DI and AX. This change adds gcWriteBarrier wrapper functions, varying only in the register used for the second argument. (Allowing variation in the first argument doesn't offer improvements, which is convenient, as it avoids quadratic API growth.) This reduces the number of register copies. The goals are reduced binary size via reduced register pressure/copies. One downside to this change is that when the write barrier is on, we may bounce through several different write barrier wrappers, which is bad for the instruction cache. Package runtime write barrier benchmarks for this change: name old time/op new time/op delta WriteBarrier-8 16.6ns ± 6% 15.6ns ± 6% -5.73% (p=0.000 n=97+99) BulkWriteBarrier-8 4.37ns ± 7% 4.22ns ± 8% -3.45% (p=0.000 n=96+99) However, I don't particularly trust these numbers. I ran runtime.BenchmarkWriteBarrier multiple times as I rebased this change, and noticed that the results have high variance depending on the parent change, perhaps due to aligment. This change was stress tested with GOGC=1 GODEBUG=gccheckmark=1 go test std.
