| * If gcc is not set to support sse (-msse) it will not accept xmm registers |
| * in the clobber list for inline asm. XMM_CLOBBERS takes a list of xmm |
| * registers to be marked as clobbered and evaluates to nothing if they are |
| * not supported, or to the list itself if they are supported. Since a clobber |
| * 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") |
