 +      [BZ #13872]
 +      * sysdeps/i386/fpu/e_powl.S (p78): New object.
 +      (__ieee754_powl): Saturate large exponents rather than testing for
 +      overflow of y*log2(x).
 +      * sysdeps/x86_64/fpu/e_powl.S: Likewise.
 +      * math/libm-test.inc (pow_test): Do not permit spurious overflow
 +      exceptions.
 +
 +      [BZ #11521]
 +      * math/s_ctan.c: Include <float.h>.
 +      (__ctan): Avoid internal overflow or cancellation in calculating
 +      denominator.
 +      * math/s_ctanf.c: Likewise.
 +      * math/s_ctanl.c: Likewise.
 +      * math/s_ctanh.c: Likewise.
 +      * math/s_ctanhf.c: Likewise.
 +      * math/s_ctanhl.c: Likewise.
 +      * math/libm-test.inc (ctan_test): Add more tests.

 +      parameters.
 +
 +2012-04-09  Roland McGrath  <roland@hack.frob.com>
 +
 +      * sysdeps/i386/fpu/bits/mathinline.h (__sincos_code): Don't clobber

 +      * sysdeps/ieee754/dbl-64/e_pow.c (huge, tiny): New variables.
 +      (__ieee754_pow): Generate overflow and underflow using huge*huge
 +      and tiny*tiny rather than just returning constant infinity or zero
 +      for large exponents.

 +      applicable cases of large exponents.
 +
 +      [BZ #706]
 +      * sysdeps/i386/fpu/e_pow.S (p10): New object.
 +      (__ieee754_pow): Use iterative multiplication algorithm only for
 +      integer exponents with absolute value below 1024.  Check for odd
 +      integer exponents when using algorithm for real exponents.
 +      * math/libm-test.inc (pow_test): Add more tests.
 +      * sysdeps/x86_64/fpu/libm-test-ulps: Update.
