+# Makefile to make executables from alpha source code files
+# and also make executables from some sample assembly files execising the alpha library

+# The alpha compiler and flags (adjust the flags as needed)
+AC := ./alpha
+AFLAGS := -tok -asc -tc -st -ir -cg
+
+# The preprocessor and flags (you should not adjust these)
+CPP := cpp
+CPPFLAGS := -P -x c
+
+# Adjust for the library your team is using (register-based or stack-based parameter passing)
+
+ALPHA_LIB = alpha_lib_reg.s   ## Register-based parameter passing
+#ALPHA_LIB = alpha_lib_st.s     ## Stack-based parameter passing
+
+# Adjust for the parameter passing approach your compiler uses:
+#   alpha_driver_reg.s for register-based parameter passing
+#   alpha_driver_st.s for stack-based parameter passing
+# This file provides a main function that packages up argv[1] (or "") as an alpha string
+# (type 1->character) and calls entry with that argument
+
+ALPHA_DRIVER = alpha_driver_reg.s   ## Register-based parameter passing
+#ALPHA_DRIVER = alpha_driver_st.s     ## Stack-based parameter passing
+
+
+# Create an assembly (.s) file from an alpha source file
+# This involves several steps:
+%.s : %.alpha
+	@mv $< $<._temporary_			# 1. rename input file so we can us it as 
+	@$(CPP) $(CPPFLAGS) $<._temporary_ > $< # 2. input to CPP, writing output to original filename
+	@$(AC) $(AFLAGS) $<			# 3. run the alpha compiler on the pre-processed file
+	@mv $<._temporary_ $<			# 4. restore the original input file
+
+
+
+# Examples of assembly code using the alpha library files
+# In these examples the calling code is in assembly, and defines main (so the driver is not included here)
+
+# Example #1: calling the printBoolean function
+printBoolean : printBoolean_reg.s
+	@gcc $< $(ALPHA_LIB) -no-pie -o $@
+
+# Example #2: calling the printInt function
+printInt : printInt_reg.s
+	@gcc $< $(ALPHA_LIB) -no-pie -o $@
+
+# Example #3: calling the reserve and release functions
+reserve_release : reserve_release_reg.s
+	@gcc $< $(ALPHA_LIB) -no-pie -o $@
+
+
+# The rule for assembling .s files and linking them together (using the gcc compiler driver)
+# to produce an executable (assuming no earlier make rule triggers first)
