[Christophe R. <cr...@us...>]

Update of /cvsroot/sbcl/sbcl/src/compiler/sparc
In directory sc8-pr-cvs1:/tmp/cvs-serv7388/src/compiler/sparc

Modified Files:
	arith.lisp parms.lisp 
Log Message:
0.8.3.72:
	Merge modular_arithmetic_branch
	... include untested modular arithmetic implementation for hppa
	... unkludge sb-md5: now implemented using natural, high-level
		lisp.  (and as a bonus, compiles to shorter code on x86
		at least).
	... passes self-tests and pfdietz-tests on x86 at least.  
		More exhaustive testing on other platforms is probably
		needed, maybe with the torturer
