Lists all targets matching the given pattern for the given build directory.
|
|
By default, only targets in the default toolchain will be matched unless a
|
|
toolchain is explicitly supplied.
|
|
|
|
If the label pattern is unspecified, list all targets. The label pattern is
|
|
not a general regular expression (see "gn help label_pattern"). If you need
|
|
more complex expressions, pipe the result through grep.
