I have 202322 built with

       /* OImode move is available only when AVX is enabled.  */
       return ((TARGET_AVX && mode == OImode)
-          || VALID_AVX256_REG_MODE (mode)
+          || (TARGET_AVX && VALID_AVX256_REG_MODE (mode))
           || VALID_SSE_REG_MODE (mode)
           || VALID_SSE2_REG_MODE (mode)
           || VALID_MMX_REG_MODE (mode)

and

-  if (TARGET_MACHO)
-    {
-      if (SSE_REGNO_P (regno) && TARGET_SSE)
-        return true;
-    }
-  else
-    {
-      if (TARGET_SSE && SSE_REGNO_P (regno)
-          && (regno < FIRST_SSE_REG + SSE_REGPARM_MAX))
-        return true;
-    }
+  if (TARGET_SSE && SSE_REGNO_P (regno)
+      && (regno < FIRST_SSE_REG + SSE_REGPARM_MAX))
+    return true;


it bootstrapped successfully and is in testing at present.
