# IBM_PROLOG_END_TAG
# 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)
