Subject: ARM: stop explicitly marking armv7k libcalls as hard-float. NFC.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b7eb4975c401709ddb044604762dee620119d46e;p=llvm

ARM: stop explicitly marking armv7k libcalls as hard-float. NFC.

Since the triple's default is hard float, the libcalls will already use VFP
registers.
