Subject: Use a signed vector type for the shift amount operand of unsigned shifts.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=bce8d4b0abc22c59d8a5d1537df22b0d13f25db8;p=clang

Use a signed vector type for the shift amount operand of unsigned shifts.
Neon shifts allow a mix of positive and negative shift amounts to shift
left or right, respectively, so the shift amount vector should always be
signed.  PR8482 (Radar 8603521).
