Subject: [PULL 50/50] target/riscv: Fix vcompress with rvv_ta_all_1s
Date: Thu, 31 Oct 2024 13:53:18 +1000	[thread overview]
Message-ID: <20241031035319.731906-51-alistair.francis@wdc.com> (raw)
In-Reply-To: <20241031035319.731906-1-alistair.francis@wdc.com>

From: Anton Blanchard <antonb@tenstorrent.com>

vcompress packs vl or less fields into vd, so the tail starts after the
last packed field. This could be more clearly expressed in the ISA,
but for now this thread helps to explain it:
