lexSpace consumed all spaces, even if the last one was part of a right delimiter like " -}}". Thus, "3 -}}" wouldn't lex as "3" and a right delimiter, but as "3", "-", and "}}". To fix that, make lexSpace stop if it encounters a right delimiter. Fixes #30948.

This change optimizes the blocks in the wasm binary by generating the entryPointLoop only if it is used and adding an unwindExit block to be able to use the short BrIf instruction for unwinding the stack. These changes were suggested by the wasm-opt tool and reduce the wasm binary size of "hello world" by 1.5%.

CL 166717 changed the way ns/op benchmark results were printed and inadvertently rounded all ns/op results down to an integer, even if they were small enough to print with digits after the decimal place. For example, prior to this change, we got output like BenchmarkFast-8 380491575 3.12 ns/op CL 166717 changed this to BenchmarkFast-8 380491575 3.00 ns/op This had the further side-effect that ns/op values between 0 and 1 would not be printed at all because they would be rounded down to 0. This CL fixes this by always recomputing the float64 value of ns/op instead of using the int64 truncation from BenchmarkResult.NsPerOp. Fixes #30997. Fixes #31005.

This change is a re-apply of the reverted CL 140863 with changes to address issue #30821. Specifically, path.Split continues to be used to split the '/'-separated import path, rather than filepath.Split. Document the algorithm for how the default executable name is determined in DefaultExecName. Rename a variable returned from os.Stat from bs to fi for consistency. CL 140863 factored out the logic to determine the default executable name from the Package.load method into a DefaultExecName function, and started using it in more places to avoid having to re-implement the logic everywhere it's needed. Most previous callers already computed the default executable name based on the import path. The load.Package method, before CL 140863, was the exception, in that it used the p.Dir value in GOPATH mode instead. There was a NOTE(rsc) comment that it should be equivalent to use import path, but it was too late in Go 1.11 cycle to risk implementing that change. This is part 1, a more conservative change for backporting to Go 1.12.2, and it keeps the original behavior of splitting on p.Dir in GOPATH mode. Part 2 will address the NOTE(rsc) comment and modify behavior in Package.load to always use DefaultExecName which splits the import path rather than directory. It is intended to be included in Go 1.13.

This reverts CL 140863 (commit bf94fc3a). Reason for revert: There was a potential problem spotted in the original fix, which resulted in it being rolled back from release-branch.go1.12 and not included in Go 1.12.1 release. We intend to improve the fix and include it in Go 1.12.2 instead. To make the fix easier to backport, revert this change before re-applying the improved fix (next commit).

Introduce a new linker command line option "-strictdups", which enables sanity checking of "ok to duplicate" symbols, especially DWARF info symbols. Acceptable values are 0 (no checking) 1 (issue warnings) and 2 (issue a fatal error checks fail). Currently if we read a DWARF symbol (such as "go.info.PKG.FUNCTION") from one object file, and then encounter the same symbol later on while reading another object file, we simply discard the second one and move on with the link, since the two should in theory be identical. If as a result of a compiler bug we wind up with symbols that are not identical, this tends to (silently) result in incorrect DWARF generation, which may or may not be discovered depending on who is consuming the DWARF and what's being done with it. When this option is turned on, at the point where a duplicate symbol is detected in the object file reader, we check to make sure that the length/contents of the symbol are the same as the previously read symbol, and print a descriptive warning (or error) if not. For the time being this can be used for one-off testing to find problems; at some point it would be nice if we can enable it by default. Updates #30908.

A lot of the naked for loops begin like: for { v := b.Control if v.Op != OpConstBool { break } ... return true } Instead, write them out in a more compact and readable way: for v.Op == OpConstBool { ... return true } This requires the addition of two bytes.Buffer writers, as this helps us make a decision based on future pieces of generated code. This probably makes rulegen slightly slower, but that's not noticeable; the code generation still takes ~3.5s on my laptop, excluding build time. The "v := b.Control" declaration can be moved to the top of each function. Even though the rules can modify b.Control when firing, they also make the function return, so v can't be used again. While at it, remove three unnecessary lines from the top of each rewriteBlock func. In total, this results in ~4k lines removed from the generated code, and a slight improvement in readability.

The wrapper already ignores HOME and TMPDIR, but after GO111MODULE was flipped to on for the standard library, cmd/go tests started failing without a valid and writable GOCACHE.

To build for watchOS and tvOS the Apple toolchain requires a Mach-O load command that matches the platform for all object files in a build. The go.o object file produced by the Go linker contains no such command. The loader commands are mutually exclusive so we need to pick the right one. Fortunately, cgo must be enabled for watchOS and tvOS to be useful, so we can copy the first loader command we find in the object files produced by the host compiler. Add a test that builds a small program for tvOS to test both this CL and the previous CL that added bitcode support.

The original goal of rounding to readable b.N was to make it easier to eyeball times. However, proper analysis requires tooling (such as benchstat) anyway. Instead, take b.N as it comes. This will reduce the impact of external noise such as GC on benchmarks. This requires reworking our iteration estimates. We used to calculate the estimated ns/op and then divide our target ns by that estimate. However, this order of operations was destructive when the ns/op was very small; rounding could hide almost an order of magnitude of variation. Instead, multiply first, then divide. Also, make n an int64 to avoid overflow. Prior to this change, we attempted to cap b.N at 1e9. Due to rounding up, it was possible to get b.N as high as 2e9. This change consistently enforces the 1e9 cap. This change also reduces the wall time required to run benchmarks. Here's the impact of this change on the wall time to run all benchmarks once with benchtime=1s on some std packages: name old time/op new time/op delta bytes 306s ± 1% 238s ± 1% -22.24% (p=0.000 n=10+10) encoding/json 112s ± 8% 99s ± 7% -11.64% (p=0.000 n=10+10) net/http 54.7s ± 7% 44.9s ± 4% -17.94% (p=0.000 n=10+9) runtime 957s ± 1% 714s ± 0% -25.38% (p=0.000 n=10+9) strings 262s ± 1% 201s ± 1% -23.27% (p=0.000 n=10+10) [Geo mean] 216s 172s -20.23% Updates #24735 Change-Id: I7e38efb8e23c804046bf4fc065b3f5f3991d0a15 Reviewed-on: https://go-review.googlesource.com/c/go/+/112155Reviewed-by:

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>

This lets us get rid of a handful of cmd/vet/whitelist/all.txt entries, since the stdmethods pass is now happy with the encoding/xml package.

As proposed in Issue #29934, update errors produced by the os package to work with errors.Is sentinel tests. For example, errors.Is(err, os.ErrPermission) is equivalent to os.IsPermission(err) with added unwrapping support. Move the definition for os.ErrPermission and others into the syscall package. Add an Is method to syscall.Errno and others. Add an Unwrap method to os.PathError and others.
