CSE 401 Compilers Class

Assignments / #1

Due Friday, 4/11/97

	Build the initial PL/0 compiler.
	Compile and run the PL/0 squares and fib sample programs. They will be in the directory when you copy your version of the compiler. NOTE: PL/0 generates MIPS assembly code, even when you build and compile on the alphas (orcas/sanjuan), so you will need to run the PL/0-generated code on the spim program under the instructional alphas. We'll get additional documentation out to you on how to do this.
	Write, compile, and run a PL/0 convolve program whose input is the series of numbers s0 s1 ... sn-1 0 r0 r1 ... rn-1 and whose output is the number s0*rn-1 + s1*rn-2 +... sn-1*r0. Hint: use recursion. For this assignment, you only need to turnin your sample convolve PL/0 source using the turnin program. On lynx/wolf/grizzly/orcas/sanjuan systems, type: {sanjuan} (~/cse401/pl0)% turnin -c cse401 convolve Note for future assignments, that the argument convolve.0 can be a directory name (in which case all files in the directory will be turned in), or a file or a group of files. The man page for turnin is also available. Just type man turnin.
	Produce a textual description of the inheritance hierarchy for the PL/0 compiler. You must turn in hardcopy for this assignment in class.
