Overview
|
|
--------
|
|
The Merge program is designed to merge the contents of similar modules into a
|
|
single module for size reduction. The combined module will link in one copy of
|
|
the libraries, rather than have multiple copies of the libraries linked in to
|
|
each individual driver.
|
|
|
|
Rules:
|
|
The ModuleType must be identical for each of the (leaf) modules.
|
|
At least one architecture type must be common for all modules, and the merged
|
|
module will only support the common architecture types.
|
|
ALL modules to be merged must be in a directory structure below the location
|
|
of the merged module.
|
|
The package must be within a directly directory line with the merged module's
|
|
MSA file. (Parent directories.)
|
|
The copying of the files from the "leaf" directory into the merge module's
|
|
directory structure must be handled by an external program.
|
|
The merge program must be run everytime a leaf module is modified.
|
|
The external copy program must also be run everytime a leaf module is modified.
|
|
Two or more leaf modules must be specified.
|
|
The merged module must be added to a package (SPD) file before it can be used.
|
|
PCD Driver Modules cannot be merged, nor combined with other modules.
|
|
Leaf Module Global BuildOptions and UserExtensions are not merged.
