Subject: [PATCH 0/1] middle-end: Fix bit position comparison
Date: Wed, 27 Jul 2022 11:44:36 +0800 [thread overview]
Message-ID: <20220727034437.154625-1-juzhe.zhong@rivai.ai> (raw)
From: zhongjuzhe <juzhe.zhong@rivai.ai>
Hi, variable "bitpos" is compute using bitsize. I think it makes
sense for bit position checking whether it is out-of-bounds to
array using GET_MODE_BITSIZE instead of GET_MODE_PRECISION.
This patch is useful for RVV (RISC-V 'V') support that I am
going to push upstream. Thanks!
