From: Daniel Sanders Date: Tue, 24 Jun 2014 13:00:32 +0000 (+0000) Subject: [mips] Added support for assembling sdbbp. X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=90be077d09df2f577448105c6dfd6ef78c4e6b6f;p=oota-llvm.git [mips] Added support for assembling sdbbp. Summary: This instruction is re-encoded in MIPS32r6/MIPS64r6 without changing the restrictions. We hadn't implemented it for earlier ISA's so it has been added to those too.
