Subject: prune math code on archs with binary64 long double
X-Git-Tag: v1.1.5~23
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0c32c2635eedfcd6af3606735ac38197f8705734;p=oweals%2Fmusl.git

prune math code on archs with binary64 long double

__polevll, __p1evll and exp10l were provided on archs when long double
is the same as double. The first two were completely unused and exp10l
can be a wrapper around exp10.
