# Makefile that defines how we build .o files from .S and .c
#    Currently, we are using power-pc ppe assembler
#
# Macros:
#    __GENERATE_PPE_OBJECTRULES: Macro to compiler .S/.c into .o
#    Extra step required for PPC2PPE environment .s to .es to .o
#
#    For the PPE native compiler, it is anticipated that eventually
#    the .o will be generated directly from source, but until it's
#    mature, an intermediate .s is generated.
#
#    The Trace strings are also extracted at this point.
#
# Inputs:
#    $1 == output path
#    $2 == src path
#    $3 == TARGET tool chain
# $1/%.o: private LOCALCOMMONFLAGS += $$($$(@F)_COMMONFLAGS)
