[PATCH 07/15] tcg/arm: Implement andc, orc, abs, neg, not vector operati


From: Richard Henderson
Subject: [PATCH 07/15] tcg/arm: Implement andc, orc, abs, neg, not vector operations
Date: Thu, 24 Dec 2020 14:45:06 -0800

These logical and arithmetic operations are optional, but are
trivial to accomplish with the existing infrastructure.
