Go Tool Shared Flags
Internal
Overview
These flags are shared by the build, clean, get, install, list, run, and test commands
-a
Force rebuilding of packages that are already up-to-date.
-n
Print the commands but do not run them.
-p n
the number of programs, such as build commands or
test binaries, that can be run in parallel.
The default is the number of CPUs available, except
on darwin/arm which defaults to 1.
-race
enable data race detection.
Supported only on linux/amd64, freebsd/amd64, darwin/amd64 and windows/amd64.
-msan
enable interoperation with memory sanitizer.
Supported only on linux/amd64,
and only with Clang/LLVM as the host C compiler.
-v
print the names of packages as they are compiled.
-work
print the name of the temporary work directory and
do not delete it when exiting.
-x
print the commands.
-asmflags 'flag list' arguments to pass on each go tool asm invocation. -buildmode mode build mode to use. See 'go help buildmode' for more. -compiler name name of compiler to use, as in runtime.Compiler (gccgo or gc). -gccgoflags 'arg list' arguments to pass on each gccgo compiler/linker invocation. -gcflags 'arg list' arguments to pass on each go tool compile invocation. -installsuffix suffix a suffix to use in the name of the package installation directory, in order to keep output separate from default builds. If using the -race flag, the install suffix is automatically set to race or, if set explicitly, has _race appended to it. Likewise for the -msan flag. Using a -buildmode option that requires non-default compile flags has a similar effect. -ldflags 'flag list' arguments to pass on each go tool link invocation. -linkshared link against shared libraries previously created with -buildmode=shared. -pkgdir dir install and load all packages from dir instead of the usual locations. For example, when building with a non-standard configuration, use -pkgdir to keep generated packages in a separate location. -tags 'tag list' a list of build tags to consider satisfied during the build. For more information about build tags, see the description of build constraints in the documentation for the go/build package. -toolexec 'cmd args' a program to use to invoke toolchain programs like vet and asm. For example, instead of running asm, the go command will run 'cmd args /path/to/asm <arguments for asm>'.
The list flags accept a space-separated list of strings. To embed spaces in an element in the list, surround it with either single or double quotes.
