Subject: (atof_generic): Calculate maximum number of useful digits in integer
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a5ac3a14a11e6028c79cc21898bc5f96fcb7fc6e;p=binutils-gdb.git

(atof_generic): Calculate maximum number of useful digits in integer
arithmetic, to eliminate only source of dependence on floating point support,
which currently doesn't work yet on the Alpha.
