By unrolling the cycle 4x and 2x, and using "LDP", "STP" instructions, this CL can reduce the "load" cost and improve performance.

This change modifies Go to disable loading of users' shell history for TestTerminalSignal tests. TestTerminalSignal, as part of its workload, will execute a new interactive bash shell. Bash will attempt to load the user's history from the file pointed to by the HISTFILE environment variable. For users with large histories that may take up to several seconds, pushing the whole test past the 5 second timeout and causing it to fail.

This CL moves the load/store combining tests into asmcheck. In addition at being more compact, it's also now easier to spot what it is missing in each architecture. While doing so, I think I uncovered a bug in ppc64le and arm64 rules, because they fail to load/store combine in non-trivial functions. Not sure why, I'll open an issue.

Before this change, in case of any failure, asmcheck was dumping to stderr the whole output of compile -S, which can be very long if it contains multiple functions. Make it so it filters the output to only display the assembly output of functions for which at least one opcode check failed. This greatly simplifies debugging.

Currently, the top-level testsuite always uses whatever version of Go is found in the PATH to execute all the tests. This forces the developers to tweak the PATH to run the testsuite. Change it to use the same version of Go used to run run.go. This allows developers to run the testsuite using the tip compiler by simply saying "../bin/go run run.go". I think this is a better solution compared to always forcing "../bin/go", because it allows developers to run the testsuite using different Go versions, for instance to check if a new test is fixed in tip compared to the installed compiler.

The previous type cache is quadratic in time in the situation where new types are continually encountered. Now that it is possible to dynamically create new types with the reflect package, this can cause json to perform very poorly. Switch to sync.Map which does well when the cache has hit steady state, but also handles occasional updates in better than quadratic time. benchmark old ns/op new ns/op delta BenchmarkTypeFieldsCache/MissTypes1-8 14817 16202 +9.35% BenchmarkTypeFieldsCache/MissTypes10-8 70926 69144 -2.51% BenchmarkTypeFieldsCache/MissTypes100-8 976467 208973 -78.60% BenchmarkTypeFieldsCache/MissTypes1000-8 79520162 1750371 -97.80% BenchmarkTypeFieldsCache/MissTypes10000-8 6873625837 16847806 -99.75% BenchmarkTypeFieldsCache/HitTypes1000-8 7.51 8.80 +17.18% BenchmarkTypeFieldsCache/HitTypes10000-8 7.58 8.68 +14.51% The old implementation takes 12 minutes just to build a cache of size 1e5 due to the quadratic behavior.

Move the IndexByte function from the runtime to a new bytealg package. The new package will eventually hold all the optimized assembly for groveling through byte slices and strings. It seems a better home for this code than randomly keeping it in runtime. Once this is in, the next step is to move the other functions (Compare, Equal, ...). Update #19792 This change seems complicated enough that we might just declare "not worth it" and abandon. Opinions welcome. The core assembly is all unchanged, except minor modifications where the code reads cpu feature bits. The wrapper functions have been cleaned up as they are now actually checked by vet.

Dsymutil, an utility used on macOS when externally linking executables, does not support base address selector entries in debug_ranges. CL 73271 worked around this problem by removing base address selectors and emitting CU-relative relocations for each list entry. This commit, as an optimization, reintroduces the base address selectors and changes the linker to remove them again, but only when it knows that it will have to invoke the external linker on macOS.

When generating location lists, batch up changes for all zero-width instructions, not just phis. This prevents the creation of location list entries that don't actually cover any instructions. This isn't perfect because of the caveats in the prior CL (Copy is zero-width sometimes) but in practice this seems to fix all of the empty lists in std.

1. Detect and remove the markers of lexical scopes that don't contain any variables early in noder, instead of waiting until the end of DWARF generation. This saves memory by never allocating some of the markers and optimizes some of the algorithms that depend on the number of scopes. 2. Assign scopes to Progs by doing, for each Prog, a binary search over the markers array. This is faster, compared to sorting the Prog list because there are fewer markers than there are Progs. completed 15 of 15, estimated time remaining 0s (eta 2:30PM) name old time/op new time/op delta Template 274ms ± 5% 260ms ± 6% -4.91% (p=0.000 n=15+15) Unicode 126ms ± 5% 127ms ± 9% ~ (p=0.856 n=13+15) GoTypes 861ms ± 5% 857ms ± 4% ~ (p=0.595 n=15+15) Compiler 4.11s ± 4% 4.12s ± 5% ~ (p=1.000 n=15+15) SSA 10.7s ± 2% 10.9s ± 4% +2.01% (p=0.002 n=14+14) Flate 163ms ± 4% 166ms ± 9% ~ (p=0.134 n=14+15) GoParser 203ms ± 4% 205ms ± 6% ~ (p=0.461 n=15+15) Reflect 544ms ± 5% 549ms ± 4% ~ (p=0.174 n=15+15) Tar 249ms ± 9% 245ms ± 6% ~ (p=0.285 n=15+15) XML 286ms ± 4% 291ms ± 5% ~ (p=0.081 n=15+15) [Geo mean] 528ms 529ms +0.14% name old user-time/op new user-time/op delta Template 358ms ± 7% 354ms ± 5% ~ (p=0.242 n=14+15) Unicode 189ms ±11% 191ms ±10% ~ (p=0.438 n=15+15) GoTypes 1.15s ± 4% 1.14s ± 3% ~ (p=0.405 n=15+15) Compiler 5.36s ± 6% 5.35s ± 5% ~ (p=0.588 n=15+15) SSA 14.6s ± 3% 15.0s ± 4% +2.58% (p=0.000 n=15+15) Flate 214ms ±12% 216ms ± 8% ~ (p=0.539 n=15+15) GoParser 267ms ± 6% 270ms ± 5% ~ (p=0.569 n=15+15) Reflect 712ms ± 5% 709ms ± 4% ~ (p=0.894 n=15+15) Tar 329ms ± 8% 330ms ± 5% ~ (p=0.974 n=14+15) XML 371ms ± 3% 381ms ± 5% +2.85% (p=0.002 n=13+15) [Geo mean] 705ms 709ms +0.62% name old alloc/op new alloc/op delta Template 38.0MB ± 0% 38.4MB ± 0% +1.27% (p=0.000 n=15+14) Unicode 28.8MB ± 0% 28.8MB ± 0% +0.16% (p=0.000 n=15+14) GoTypes 112MB ± 0% 114MB ± 0% +1.64% (p=0.000 n=15+15) Compiler 465MB ± 0% 474MB ± 0% +1.91% (p=0.000 n=15+15) SSA 1.48GB ± 0% 1.53GB ± 0% +3.32% (p=0.000 n=15+15) Flate 24.3MB ± 0% 24.8MB ± 0% +1.77% (p=0.000 n=14+15) GoParser 30.7MB ± 0% 31.1MB ± 0% +1.27% (p=0.000 n=15+15) Reflect 76.3MB ± 0% 77.1MB ± 0% +1.03% (p=0.000 n=15+15) Tar 39.2MB ± 0% 39.6MB ± 0% +1.02% (p=0.000 n=13+15) XML 41.5MB ± 0% 42.1MB ± 0% +1.45% (p=0.000 n=15+15) [Geo mean] 77.5MB 78.7MB +1.48% name old allocs/op new allocs/op delta Template 385k ± 0% 387k ± 0% +0.54% (p=0.000 n=15+15) Unicode 342k ± 0% 343k ± 0% +0.10% (p=0.000 n=15+15) GoTypes 1.19M ± 0% 1.19M ± 0% +0.64% (p=0.000 n=14+15) Compiler 4.51M ± 0% 4.54M ± 0% +0.53% (p=0.000 n=15+15) SSA 12.2M ± 0% 12.4M ± 0% +1.16% (p=0.000 n=15+15) Flate 234k ± 0% 236k ± 0% +0.63% (p=0.000 n=14+15) GoParser 318k ± 0% 320k ± 0% +0.63% (p=0.000 n=15+15) Reflect 974k ± 0% 977k ± 0% +0.28% (p=0.000 n=15+15) Tar 395k ± 0% 397k ± 0% +0.38% (p=0.000 n=15+13) XML 404k ± 0% 407k ± 0% +0.55% (p=0.000 n=15+15) [Geo mean] 794k 799k +0.55% name old text-bytes new text-bytes delta HelloSize 680kB ± 0% 680kB ± 0% ~ (all equal) name old data-bytes new data-bytes delta HelloSize 9.62kB ± 0% 9.62kB ± 0% ~ (all equal) name old bss-bytes new bss-bytes delta HelloSize 125kB ± 0% 125kB ± 0% ~ (all equal) name old exe-bytes new exe-bytes delta HelloSize 1.11MB ± 0% 1.12MB ± 0% +1.11% (p=0.000 n=15+15) Change-Id: I95a0173ee28c52be1a4851d2a6e389529e74bf28 Reviewed-on: https://go-review.googlesource.com/95396 Run-TryBot: Alberto Donizetti <alb.donizetti@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:
