# Building XPIDLs effectively consists of two steps:
|
|
#
|
|
# 1) Staging all .idl files to a common directory.
|
|
# 2) Doing everything with the .idl files.
|
|
#
|
|
# Each .idl file is processed into a .h file and typelib information.
|
|
# The .h file shares the same stem as the input file and is installed
|
|
# in the common headers include directory.
|
|
#
|
|
# XPIDL files are logically grouped together by modules. The typelib
|
|
# information for all XPIDLs in the same module is linked together into
|
|
# an .xpt file having the name of the module.
|
|
#
|
|
# As an optimization to reduce overall CPU usage, we process all .idl
|
|
# belonging to a module with a single command invocation. This prevents
|
|
# redundant parsing of .idl files and significantly reduces CPU cycles.
|
|
#
|
|
# Future improvement: Headers are currently written to a local directory then
|
|
# installed in the distribution directory. It is preferable to write headers
|
|
# directly into the distribution directory. However, PGO builds remove the dist
|
|
# directory via rm -rf (with no regards to manifests). Since the cost of
|
|
# processing XPIDL files is not trivial, it is preferrable to cache the headers
|
|
# and reinstall them rather than regenerate them. Ideally the dist pruning is
|
|
# performed with manifests. At that time we can write headers directly to the
|
|
# dist directory.
|
|
|
|
# For dependency files.
