2004-09-10 Richard Sandiford <rsandifo@redhat.com>
+ * config/frv/frv.md (UNSPEC_MASACCS, UNSPEC_MDASACCS): New constants.
+ (maddaccs, msubaccs, *maddacc): Turn operand 0 into a single ACC/ACCG
+ pair. Remove match_dup from inputs. Remove masaccs handling.
+ (mdaddaccs, mdsubaccs, *mdaddacc): Likewise a dual ACC/ACCG pair.
+ (masaccs, mdasaccs): Turn into define_insns.
+
+2004-09-10 Richard Sandiford <rsandifo@redhat.com>
+
* tree-tailcall.c (process_assignment): Only do accumulator transforms
for floating-point types if flag_unsafe_math_optimizations.
