Update.
1998-05-06 12:51 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/i386/fpu/bits/mathinline.h (pow): Use long long int for
test for integer.
* sysdeps/libm-i387/e_pow.S: Correctly shift double word.
* sysdeps/libm-i387/e_powl.S: Likewise.
1998-03-31 Wolfram Gloger <wmglo@dent.med.uni-muenchen.de>
* malloc/malloc.c (chunk2mem_check, top_check): New functions.
(malloc_check, free_check, realloc_check, memalign_check): Use
them to improve overrun checking. Overruns of a single byte and
corruption of the top chunk are now detected much more reliably.
1998-05-06 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* math/libm-test.c (pow_test): Add test for special value from PR
libc/590.
