Subject: [PATCH v3 13/23] i386: Rewrite simple integer vector helpers
Date: Thu, 1 Sep 2022 09:48:32 +0200 [thread overview]
Message-ID: <20220901074842.57424-14-pbonzini@redhat.com> (raw)
In-Reply-To: <20220901074842.57424-1-pbonzini@redhat.com>
From: Paul Brook <paul@nowt.org>
Rewrite the "simple" vector integer helpers in preperation for AVX support.
While the current code is able to use the same prototype for unary
(a = F(b)) and binary (a = F(b, c)) operations, future changes will cause
them to diverge.
No functional changes to existing helpers
