From da43e287d1917a25594f95c7c519ded637c7ea50 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Wed, 25 Jan 2023 11:24:32 +0000 Subject: [PATCH] aarch64: Restore generation of SVE UQDEC instructions The addition of TARGET_CSSC meant that we wouldn't generate SVE UQDEC instructions unless +cssc was also enabled.
