These intrinsics are introduced for compatibility purposes. Besides MSVC GCC also supports it in its main trunk; ICC supports it on Windows and is going to support in the next version on Linux. 2013/12/18 Joerg Sonnenberger <joerg at britannica.bec.de> > On Tue, Dec 17, 2013 at 01:05:10PM -0800, David Majnemer wrote: > > This intrinsic seems very ill-defined, apparently it can be

...-Oz memmove lowering for example. I don't think LLVM will ever really support capturing ALU flags from previous ops without "using" the operation. LLVM does have overflow intrinsics though: http://llvm.org/docs/LangRef.html#id1164 On Tue, Dec 17, 2013 at 1:02 AM, Alexey Volkov <avolkov.intel at gmail.com>wrote: > Hello all, > > I am trying to implement intrinsics __readeflags and __writeeflags reading > and writing EFLAGS register on x86. > These intrinsics expand to two instructions popf and push to register for > __readeflags and pushf and pop to register...

Hello all, I am trying to implement intrinsics __readeflags and __writeeflags reading and writing EFLAGS register on x86. These intrinsics expand to two instructions popf and push to register for __readeflags and pushf and pop to register for __writeeflags. These instructions are not connected explicitly so I can't use patterns in .td file to match intrinsics. I tried to implement custom

Hello All, I'm trying to figure out why xen-utils-common 3.2 doesn't suport bridging on multiple interfaces. I've been digging around /etc/xen/scripts/network-bridges. And modified it so that during boot, when executed the script writes into /tmp/netbr file, but I commented out code that actually creates bridges. I discovered that this script is called three times during boot, I
