+ * gencode.c (expand_ppi_code): Comment spelling fix.
+
+2003-07-25 Michael Snyder <msnyder@redhat.com>
+
+ * gencode.c (pshl): Change < to <= (shift by 16 is allowed).

+
+ * gencode.c: Fix typo in comment.
+
+2003-07-23 Michael Snyder <msnyder@redhat.com>
+
+ * gencode.c: A few more fix-ups of refs and defs.
+ (frchg): Raise SIGILL if in double-precision mode.
+ (ldtlb): We don't simulate cache, so this is a no-op.
+ (movsxy_tab): Correct a few bit pattern errors.
+
+2003-07-09 Michael Snyder <msnyder@redhat.com>
+
+ * gencode.c (prnd): Clear LSW of result to zeros.
+ * gencode.c (pmuls): Expression is mis-parenthesized.
+ * gencode.c (ppi_gensim): For a conditional ppi insn, if the
+ condition is false, we want to return (not break). A break
+ will take us to the end of the function where registers will
+ be updated, whereas the desired outcome is for nothing to change.
