(Thanks to Takeru Ohta) + * bug fix: On SPARC, a limitation on the number of code constants emittable + by the compiler has been lifted, allowing certain long functions to + compiled and assembled which had previously been unsupported; fixes + cl-bench on this ISA (lp#1008996). + * bug fix: potential for infinite recursion during compilation of CLOS slot + typechecks when dependency graph had loops.
