Accuracy tests for libm This patch adds more tests for math functions to address coverage issue of math functions discussed in: https://android-review.googlesource.com/#/c/49653/ https://android-review.googlesource.com/#/c/94780/ These are data sets used in regression tests for the Intel the math library (libm). They were collected over a long period of testing various libm implementations. The data sets contain function specific data (special and corner cases such as +/-0, maximum/minimum normalized numbers, +/-infinity, QNaN/SNaN, maximum/minimum denormal numbers, arguments that would produce close to overflow/underflow results, known hard-to-round cases, etc), implementation specific data (arguments close to table look-up values for different polynomial approximations, worst cases for range reduction algorithms) and other data with interesting bit patterns. The reference values are computed with Maple and were converted into hexadecimal format.
