Subject: [Qemu-devel] [PATCH 01/13] tcg: extend max tcg opcodes when using 64-on-32bit
Date: Wed, 4 May 2011 14:09:30 +0200 [thread overview]
Message-ID: <1304510982-30810-2-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1304510982-30810-1-git-send-email-agraf@suse.de>
When running a 64 bit guest on a 32 bit host, we tend to use more TCG ops
than on a 64 bit host. Reflect that in the reserved opcode amount constant.
Signed-off-by: Alexander Graf <agraf@suse.de>

v4 -> v5:
- only increase MAX_OP_PER_INSTR when running 64-on-32
