| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not left-shift a negative number (inducing undefined behavior in C/C++) in exp(3), expf(3), expm1(3) and expm1f(3) during intermediate computations that compute the IEEE-754 bit pattern for |2**k| for integer |k|. The implementations of exp(3), expf(3), expm1(3) and expm1f(3) need to compute IEEE-754 bit patterns for 2**k in certain places. (k is an integer and 2**k is exactly representable in IEEE-754.) Currently they do things like 0x3FF0'0000+(k<<20), which is to say they take the bit pattern representing 1 and then add directly to the exponent field to get the desired power of two. This is fine when k is non-negative. But when k<0 (and certain classes of input trigger this), this left-shifts a negative number -- an operation with undefined behavior in C and C++. The desired semantics can be achieved by instead adding the possibly-negative k to the IEEE-754 exponent bias to get the desired exponent field, _then_ shifting that into its proper overall position. (Note that in case of s_expm1.c and s_expm1f.c, there are SET_HIGH_WORD and SET_FLOAT_WORD uses further down in each of these files that perform shift operations involving k, but by these points k's range has been restricted to 2 < k <= 56, and the shift operations under those circumstances can't do anything that would be UB.)

No functional changes, as verified with md5. r227520 (das) Further reduce diffs with OpenBSD's arc4random. The main functional change here is to ensure that when a process forks after arc4random is seeded, the parent and child don't observe the same random sequence. OpenBSD's fix introduces some additional overhead in the form of a getpid() call. The only significant remaining difference between our arc4random and OpenBSD's is in how we seed the generator in arc4_stir(). Notes: svn path=/stable/8/; revision=267380
