 You need not define this macro if it would always evaluate to zero.

-@deftypefn {Target Hook} tree TARGET_MD_ASM_CLOBBERS (tree @var{outputs}, tree @var{inputs}, tree @var{clobbers})
-This target hook should add to @var{clobbers} @code{STRING_CST} trees for
-any hard regs the port wishes to automatically clobber for an asm.
-It should return the result of the last @code{tree_cons} used to add a
-clobber.  The @var{outputs}, @var{inputs} and @var{clobber} lists are the
-corresponding parameters to the asm and may be inspected to avoid
-clobbering a register that is an input or output of the asm.  You can use
-@code{tree_overlaps_hard_reg_set}, declared in @file{tree.h}, to test
-for overlap with regards to asm-declared registers.
