 # This file defines variables and macros which are used in the makefiles to 

 # allow distributions to augment or replace common hotspot code with 

 # distribution-specific source files. This capability is disabled when

 # an OPENJDK build is requested, unless HS_ALT_SRC_REL has been set externally.

 # Requires: GAMMADIR

 # Provides:

 #   variables: HS_COMMON_SRC, HS_ALT_SRC, HS_COMMON_SRC_REL, and HS_ALT_SRC_REL

 #   functions: altsrc-equiv, if-has-altsrc, altsrc, altsrc-replace

 ## altsrc-equiv 

 # 

 # Convert a common source path to an alternative source path

 #

 # Parameter: An absolute path into the common sources

 # Result: The matching path to the alternate-source location

 #

 altsrc-equiv=$(subst $(HS_COMMON_SRC)/,$(HS_ALT_SRC)/,$(1))

 ## if-has-altsrc

 #

 # Conditional macro to test for the existence of an alternate source path

 #

 # Parameter: An absolute path into the common sources

 # Parameter: Result if the alternative-source location exists

 # Parameter: Result if the alternative-source location does not exist

 # Result: expands to parameter 2 or 3 depending on existence of alternate source

 #

 if-has-altsrc=$(if $(wildcard $(call altsrc-equiv,$(1))),$(2),$(3))

 ## altsrc

 #

 # Converts common source path to alternate source path if the alternate 

 # path exists, otherwise evaluates to nul (empty string)

 # 

 # Parameter: An absolute path into the common sources

 # Result: The equivalent path to the alternate-source location, if such a 

 #         location exists on the filesystem.  Otherwise it expands to empty.

 # 

 altsrc=$(call if-has-altsrc,$(1),$(call altsrc-equiv,$(1)))

 ## commonsrc

 # 

 # Returns parameter.

 #

 commonsrc=$(1)

 ## altsrc-replace

 #

 # Converts a common source path to an alternate source path if the alternate

 # source path exists.  Otherwise it evaluates to the input common source path.

 #

 # Parameter: An absolute path into the common sources

 # Result: A path to either the common or alternate sources

 #
