re PR debug/84637 (gcc/dbxout.c:684:14: runtime error: negation of -9223372036854775808 cannot be represented in type 'long int'; cast to an unsigned type to negate this value to itself)
PR debug/84637
* dbxout.c (dbxout_int): Perform negation in unsigned int type.
(stabstr_D): Change type of unum from unsigned int to
unsigned HOST_WIDE_INT. Perform negation in unsigned HOST_WIDE_INT
type.
