If both inputs are constant offsets from the same pointer then we can evaluate NeqPtr and EqPtr at compile time. Triggers a few times during all.bash. Removes a conditional branch in the following code: copy(x[1:], x[:]) This branch was recently added as an optimization in CL 94596. We now skip the memmove if the pointers are equal. However, in the above code we know at compile time that they are never equal. Also, when the offset is variable, check if the offset is zero rather than if the pointers are equal. For example: copy(x[a:], x[:]) This would now skip the copy if a == 0, rather than if x + a == x. Finally I've also added a rule to make IsNonNil true for pointers to values on the stack. The nil check elimination pass will catch these anyway, but eliminating them here might eliminate branches earlier.

Focus on "isfoo" funcs that take a *Node, and conver them to isFoo methods instead. This makes for more idiomatic Go code, and also more readable func names. Found candidates with grep, and applied most changes with sed. The funcs chosen were isgoconst, isnil, and isblank. All had the same signature, func(*Node) bool. While at it, camelCase the isliteral and iszero function names. Don't move these to methods, as they are only used in the backend part of gc, which might one day be split into a separate package. Passes toolstash -cmp on std cmd.

While writing CL 107315, I went back and forth for the syntax used for constraints of build environments in which the architecture did not support varitants ("plan9/amd64" vs "plan9/amd64/"). I eventually settled for the latter because the code required less heuristics (think parsing "plan9/386" vs "386/sse2") but there were a few leftovers in code and comments.

This CL makes the codegen testsuite automatically test all architecture variants for architecture specified in tests. For instance, if a test file specifies a "arm" test, it will be automatically run on all GOARM variants (5,6,7), to increase the coverage. The CL also introduces a syntax to specify only a specific variant (eg: "arm/7") in case the test makes sense only there. The same syntax also allows to specify the operating system in case it matters (eg: "plan9/386/sse2").

It was skipping dirs starting with ".", but it was missing the "_" prefix and the "testdata" name. From "go help packages": Directory and file names that begin with "." or "_" are ignored by the go tool, as are directories named "testdata". Before the change: $ go doc z # using src/cmd/go/testdata/testvendor/src/q/z package z // import "." After the fix, it falls back to the current directory, as expected when a single argument isn't found as a package in $GOPATH. TestMain needs a small adjustment to keep the tests working, as now their use of cmd/doc/testdata would normally not work. Fixes #24462.

The tabwriter tracks cells on a line-by-line basis. This can be memory-hungry when working with large input. This change adds two optimizations. First, when there's an existing cell slice for a line, don't overwrite it by appending. This helps when re-using a Writer, or when the output is broken into groups, e.g. by a blank line. We now re-use that existing cell slice. Second, we predict that the number of cells in a line will probably match those of the previous line, since tabwriter is most often used to format tables. This has a noticeable impact on cmd/objdump (#24725). It reduces allocated space by about 55%. It also speeds it up some.

RawRead assumes the callback will perform either (a) a blocking read and always return true, (b) a blocking read with a SO_RCVTIMEO set returning false on WSAETIMEDOUT, or (c) a non-blocking read returning false on WSAEWOULDBLOCK. In the latter two cases, it uses a 0-byte overlapped read for notifications from the IOCP runtime when the socket becomes readable before trying again. RawWrite assumes the callback will perform blocking write and will always return true, and makes no effort to tie into the runtime loop.

Windows process cannot run properly, if it only has GOOS and GOARCH environment variables set. It needs other environment variables. So adjust TestLarge and TestNoRet to add GOOS and GOARCH to the existing variables set instead of clearing environment.

Since the tabwriter is flushed at every symbol, it can be re-used with no impact on the output. This cuts allocated space when objdump-ing the compiler by almost 40%, and enables further upcoming improvements. It also speeds up objdump. name old time/op new time/op delta ObjdumpCompile 9.22s ± 3% 8.77s ± 3% -4.79% (p=0.000 n=10+9) Change-Id: Ief114d6c2680a4e762b5f439d3ca8dc7a89b9b27 Reviewed-on: https://go-review.googlesource.com/106978 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

We sometimes generate code like this: v473 = MOVQconst <uintptr> // constant.. v580 = MOVBstoreidx1 <mem> v1056 v473 v819 v491 // ..only used as an index Rewrite indexed stores to non-indexed version, where possible. This allows to eliminate const->register move, reducing codesize and lowering register pressure.

runtime/traceback: support tracking goroutine ancestor tracebacks with GODEBUG="tracebackancestors=N" Currently, collecting a stack trace via runtime.Stack captures the stack for the immediately running goroutines. This change extends those tracebacks to include the tracebacks of their ancestors. This is done with a low memory cost and only utilized when debug option tracebackancestors is set to a value greater than 0.
