Subject: [Qemu-devel] TCG: 128 bit ops?
Date: Thu, 4 Sep 2008 13:10:39 +0200 [thread overview]
Message-ID: <D1F4A45F-4F7A-477E-8045-4886C45949BA@gmail.com> (raw)
Hello,
Am I correct in seeing that TCG offers no i128 ops? Would this be
useful to add to TCG, internally reusing the i64/i32 code? ppc needs
128-bit temporaries for Altivec instructions. It uses a union
ppc_avr_t of (among others) two uint64_t.
Or should I just use two i64 temporaries with a local macro/helper?
It's not used much in ppc but I thought it might be useful to share
with other architectures.
Andreas
