Here is a test that shows that on at least PowerPC the basic asm is identical to the extended asm without clobber (compile with -O2 -S and -fno-ipa-icf if you want to have it easier to read). In this case, the basic asm is treated as not clobbering memory at the tree level already, before expanding to RTL.
And that IMHO, ought to be considered a bug. Jeff
