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.
