[PATCH qemu 0/9] Add mask agnostic behavior for rvv instructions


From: ~eopxd
Subject: [PATCH qemu 0/9] Add mask agnostic behavior for rvv instructions
Date: Mon, 25 Apr 2022 14:18:39 +0000

According to v-spec, agnostic elements can be either kept as undisturbed
or set elements' bits to all 1s. To distinguish the difference of mask
policies, QEMU should be able to simulate the mask agnostic behavior as
"set masked-off elements' bits to all 1s". An option 'rvv_ma_all_1s' is
added to enable the behavior, it is default as disabled.

This patch set is based on the patch set "Add tail agnostic behavior for
rvv instructions".
