> Subject: [PATCH] arm: Replace arm_builtin_vectorized_function [PR106253]
>
> This patch extends the fix for PR106253 to AArch32. As with AArch64,
> we were using ACLE intrinsics to vectorise scalar built-ins, even
> though the two sometimes have different ECF_* flags. (That in turn
> is because the ACLE intrinsics should follow the instruction semantics
> as closely as possible, whereas the scalar built-ins follow language
> specs.)
>
> The patch also removes the copysignf built-in, which only existed
> for this purpose and wasn't a “real” arm_neon.h built-in.
>
> Doing this also has the side-effect of enabling vectorisation of
> rint and roundeven. Logically that should be a separate patch,
> but making it one would have meant adding a new int iterator
> for the original set of instructions and then removing it again
> when including new functions.
>
> I've restricted the bswap tests to little-endian because we end
> up with excessive spilling on big-endian. E.g.:
>
> sub sp, sp, #8
> vstr d1, [sp]
> vldr d16, [sp]
> vrev16.8 d16, d16
> vstr d16, [sp]
> vldr d0, [sp]
> add sp, sp, #8
> @ sp needed
> bx lr
>
> Similarly, the copysign tests require little-endian because on
> big-endian we unnecessarily load the constant from the constant pool:
>
> vldr.32 s15, .L3
> vdup.32 d0, d7[1]
> vbsl d0, d2, d1
> bx lr
> .L3:
> .word -2147483648

> Tested on arm-linux-gnueabihf and armeb-eabi. OK to install?
Ok.
