Subject: [PATCH 4/5] tci: define TCG_TARGET_REG_BITS based on TCG_VADDR_BITS
Date: Fri, 23 May 2025 00:17:29 +0900 [thread overview]
Message-ID: <3edb13f42740984e2272425478bb58a6d985269e.1747922170.git.ktokunaga.mail@gmail.com> (raw)
In-Reply-To: <cover.1747922170.git.ktokunaga.mail@gmail.com>
This commit defines TCG_TARGET_REG_BITS based on the value of
TCG_VADDR_BITS. For non-wasm hosts, TCG_VADDR_BITS matches the pointer size,
so this change preserves the original behaviour. For the wasm host, this
change enables support for 64bit guests.
