---|
200 | # * For bld_blockdata, bld_dep_ext and bld_exe_name, it sets the re-generate |
---|
201 | # make-rule flag to true. |
---|
202 | # * For bld_dep_excl, in a standalone build, the method will remove the |
---|
203 | # dependency cache files for affected sub-packages. It returns an error if |
---|
204 | # the current build inherits from previous builds. |
---|
205 | # * For bld_pp, it updates the PP setting for affected sub-packages. |
---|
206 | # * For infile_ext, in a standalone build, the method will remove all the |
---|
207 | # sub-package cache files and trigger a re-build by removing most |
---|
208 | # sub-directories created by the previous build. It returns an error if the |
---|
209 | # current build inherits from previous builds. |
---|
210 | # * For outfile_ext, in a standalone build, the method will remove all the |
---|
211 | # sub-package dependency cache files. It returns an error if the current |
---|
212 | # build inherits from previous builds. |
---|
213 | # * For tool, it updates the "flags" files for any changed tools. |
