Modified files:
lib/libc/alpha/gen divrem.m4
sys/alpha/alpha divrem.m4
Log:
When required to negate the absoulte result of a division/remainder
operation (by subtracting the absolute result from 0), don't test
for overflow.
This avoids an arithmetic exception when dividing LONG_MIN by 1:
This is the only case that causes overflow, and the resulting value
is correct under 2's compliment arithmetic.
