Subject: Add ARM64 support
X-Git-Tag: RELEASE-0.4~1
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=4b072dd8e99a6085abcef2a444c90098bb6c1978;p=unikraft%2Flibs%2Flibcxx.git

Add ARM64 support

In order to compile under ARM64 we remove the definitions of __x86_64__
and __FLT16_MANT_DIG__.
