From 69d1a9377453d78ba2279fa56ae9623b3cd98673 Mon Sep 17 00:00:00 2001 From: Tom Musta Date: Thu, 18 Dec 2014 10:34:31 -0600 Subject: target-ppc: Introduce tm_enabled Bit to CPU State Add a bit (tm_enabled) to CPU state that mirrors the MSR[TM] bit. This is analogous to the other "available" bits in the MSR (FP, VSX, etc.). NOTE: Since MSR[TM] occupies big-endian bit 31, the code is wrapped with a PPC64 bit check.
