Subject: Add additional arguments for -mfpu options
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f661c5aaf070275a0e6d8994681911db5c882785;p=clang

Add additional arguments for -mfpu options

Add neon-vfpv3 to allow specifying both at the same time. This is not an
option that GCC supports, but follows the same track and should be
non-controversial.
