/* Non-zero if warn when a high/shigh reloc has no matching low reloc.
Each high/shigh reloc must be paired with it's low cousin in order to
properly calculate the addend in a relocatable link (since there is a
potential carry from the low to the high/shigh).
This option is off by default though for user-written assembler code it
might make sense to make the default be on (i.e. have gcc pass a flag
to turn it off). This warning must not be on for GCC created code as
optimization may delete the low but not the high/shigh (at least we
shouldn't assume or require it to). */
