[BZ #1877]
2005-11-17 Steven Munroe <sjmunroe@us.ibm.com>
[BZ #1877]
* string/test-strncmp.c (do_test_limit): Handle zero length and
non-zero align values.
(test_main): Correct do_test_limit tests for 64-bit.
2005-11-15 Steven Munroe <sjmunroe@us.ibm.com>
* sysdeps/powerpc/sysdep.h (PPC_FEATURE_HAS_SPE,
PPC_FEATURE_HAS_EFP_SINGLE, PPC_FEATURE_HAS_EFP_DOUBLE,
PPC_FEATURE_NO_TB, PPC_FEATURE_POWER4, PPC_FEATURE_POWER5,
PPC_FEATURE_POWER5_PLUS, PPC_FEATURE_CELL, PPC_FEATURE_970):
Define to match 2.6.15 kernel.
* sysdeps/powerpc/fpu/e_sqrt.c: Remove dl-procinfo.h include.
* sysdeps/powerpc/fpu/e_sqrtf.c: Likewise.
* sysdeps/powerpc/fpu/w_sqrtf.c: Likewise.
