+If defined, a C statement that calls the function named as the sole
+argument of this macro.  This is used in @file{crtstuff.c} if
+@code{INIT_SECTION_ASM_OP} or @code{FINI_SECTION_ASM_OP} to calls to
+initialization and finalization functions from the init and fini
+sections. By default, this macro is a simple function call.  Some
+ports need hand-crafted assembly code to avoid dependencies on
+registers initialized in the function prologue or to ensure that
+constant pools don't end up too far way in the text section.
