Overview

Package buildcfg provides access to the build configuration described by the current environment. It is for use by build tools such as cmd/go or cmd/compile and for setting up go/build's Default context.

Note that it does NOT provide access to the build configuration used to build the currently-running binary. For that, use runtime.GOOS etc as well as github.com/blahblah5555/CobaltStrikeParser-Go/lib/internal/goexperiment.

var Error error

Error is one of the errors found (if any) in the build configuration.

View Source
var Experiment, _ = func() (goexperiment.Flags, goexperiment.Flags) {
	flags, baseline, err := ParseGOEXPERIMENT(GOOS, GOARCH, envOr("GOEXPERIMENT", defaultGOEXPERIMENT))
	if err != nil {
		Error = err
	}
	return flags, baseline
}()

Experiment contains the toolchain experiments enabled for the current build.

(This is not necessarily the set of experiments the compiler itself was built with.)

experimentBaseline specifies the experiment flags that are enabled by default in the current toolchain. This is, in effect, the "control" configuration and any variation from this is an experiment.

View Source
var FramePointerEnabled = GOARCH == "amd64" || GOARCH == "arm64"

FramePointerEnabled enables the use of platform conventions for saving frame pointers.

This used to be an experiment, but now it's always enabled on platforms that support it.

Note: must agree with runtime.framepointer_enabled.

Functions

func AllExperiments

func AllExperiments() []string

AllExperiments returns a list of all experiment settings. Disabled experiments appear in the list prefixed by "no".

func Check

func Check()

Check exits the program with a fatal error if Error is non-nil.

func EnabledExperiments

func EnabledExperiments() []string

EnabledExperiments returns a list of enabled experiments, as lower-cased experiment names.

func GOEXPERIMENT

func GOEXPERIMENT() string

GOEXPERIMENT is a comma-separated list of enabled or disabled experiments that differ from the baseline experiment configuration. GOEXPERIMENT is exactly what a user would set on the command line to get the set of enabled experiments.

func Getgoextlinkenabled

func Getgoextlinkenabled() string

func ParseGOEXPERIMENT

func ParseGOEXPERIMENT(goos, goarch, goexp string) (flags, baseline goexperiment.Flags, err error)

ParseGOEXPERIMENT parses a (GOOS, GOARCH, GOEXPERIMENT) configuration tuple and returns the enabled and baseline experiment flag sets.

TODO(mdempsky): Move to github.com/blahblah5555/CobaltStrikeParser-Go/lib/internal/goexperiment.

func UpdateExperiments

func UpdateExperiments(goos, goarch, goexperiment string)

UpdateExperiments updates the Experiment global based on a new GOARCH value. This is only required for cmd/go, which can change GOARCH after program startup due to use of "go env -w".
