When you build with ``mach build``, there are some special targets that can be
built. This page attempts to document them.
Partial Tree Targets
The targets in this section only build part of the tree. Please note that
partial tree builds can be unreliable. Use at your own risk.
Build the *export* tier. The *export* tier builds everything that is
required for C/C++ compilation. It stages all header files, processes
Build the *compile* tier. The *compile* tier compiles all C/C++ files.
Build the *libs* tier. The *libs* tier performs linking and performs
most build steps which aren't related to compilation.
Build the *tools* tier. The *tools* tier mostly deals with supplementary
tools and compiled tests. It will link tools against libXUL, including
compiled test binaries.
Recompiles and relinks C/C++ files. Only works after a complete normal
build, but allows for much faster rebuilds of C/C++ code. For performance
reasons, however, it skips nss, nspr, icu and ffi. This is targeted to
improve local developer workflow when touching C/C++ code.
Process install manifests. Install manifests handle the installation of
files into the object directory.
Unless ``NO_REMOVE=1`` is defined in the environment, files not accounted
in the install manifests will be deleted from the object directory.
Processes the tests install manifest.
The targets in this section correspond to common build-related actions. Many
of the actions in this section are effectively frontends to shell scripts.
These actions will likely all be replaced by mach commands someday.
Create a symbols archive for the current build.
This must be performed after a successful build.
Run build system tests.
