Still getting (but only) these differences:

$ ./gas/as-new -o power7.o -mpower7 ./gas/testsuite/gas/ppc/power7.s 
$ ./binutils/objdump -d -Many power7.o >d-any
$ ./binutils/objdump -d -Mpower7 power7.o >d-power7
$ diff -u d-any d-power7 
-  98:	7d 5c 02 a6 	mfspr   r10,28
+  98:	7d 5c 02 a6 	mfcfar  r10
-  9c:	7d 7c 03 a6 	mtspr   28,r11
+  9c:	7d 7c 03 a6 	mtcfar  r11
- 14c:	7e 08 4a 2c 	dcbt    16,r8,r9
+ 14c:	7e 08 4a 2c 	dcbtt   r8,r9
- 150:	7e 08 49 ec 	dcbtst  16,r8,r9
+ 150:	7e 08 49 ec 	dcbtstt r8,r9

Is -Mpower7 therefore still required or could be the current `d-any' variants
also overriden for -Many by their `d-power7' variants?


Thanks,
Jan
