Subject: LibTomMath: Use 64-bit mode for mp_digit
X-Git-Tag: hostap_2_0~639
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e22ba3e3908c8d9027594397d4a3e811a0f43c06;p=thirdparty%2Fhostap.git

LibTomMath: Use 64-bit mode for mp_digit

For 64-bit x86 builds, enable 64-bit mode to optimize bignum operations
with the internal LibTomMath version.
