Subject: [PATCH 0/1] tricore: fixed faulty conditions for extr and imask
Date: Wed, 10 Feb 2021 09:26:49 +0100	[thread overview]
Message-ID: <20210210082650.5516-1-david.brenken@efs-auto.org> (raw)

From: Andreas Konopik <andreas.konopik@efs-auto.de>

Hello together,

we have fixed a few conditions leading to incorrect intermediate code
generation. RCPW_IMASK, RRPW_EXTR, RRPW_EXTR_U and RRPW_IMASK invoke
undefined behavior for "pos + width > 32", which is also checked in
tcg_gen_extract_tl(). RRRW_EXTR_U invokes undefined behavior for
"width == 0", hence we removed that condition.
