- * list may not be empty, XMM_CLOBBERS_ONLY should be used if the xmm
- * registers are the only in the clobber list.
- * For example a list with "eax" and "xmm0" as clobbers should become:
- * : XMM_CLOBBERS("xmm0",) "eax"
- * and a list with only "xmm0" should become:
- * XMM_CLOBBERS_ONLY("xmm0")
