37146 - The atomic.c test prints incorrect output

Status: RESOLVED FIXED

(NSPR :: NSPR, defect, P3)

Description

[Wan-Teh Chang]

The atomic.c test prints incorrect output.
It is supposed to print the old value of
the variable being atomically changed, but
it prints the new value.

The fix is to save the old value in 'oldval'
before each atomic operation and print 'oldval'.

I also fixed the checks in the test to verify
the new spec. of PR_AtomicIncrement/Decrement:
they return the result, not just the sign of
the result, of the increment/decrement operation.

The fix is checked in on the main trunk.
