Subject: [AArch64] Overload NEON signed/unsigned floating-point convert to fixed-point
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f33217a0633428266ecae1c4da8f278ee7d75be8;p=clang

[AArch64] Overload NEON signed/unsigned floating-point convert to fixed-point
and fixed-point convert to floating-point LLVM AArch64 intrinsics.
