Hi all, LLVM is smart that it can synthesize llvm.memset, llvm.memcpy etc. from loops, which can be lowered into calls to memset, memcpy and so on. Is there an option that can disable this optimization? For some cases, I do not want the code to depend on libc. Thanks in advance!

This patch synthesizes haddps/haddpd/hsubps/hsubpd instructions from floating point additions and subtractions of appropriate vector shuffles. To do this I introduced new x86 FHADD and FHSUB opcodes. These need to be wired up somehow in the .td file to the appropriate instructions. Since I have no idea how tablegen works I just hacked it in horribly. It works, but breaks support for the hadd

Some things we've used comments for: - Tag instructons with source line information (customers really want this). - Tag instructions as register spills or reloads. - Tag instructions as top-of-loop, with nesting information (we use this to do some st...

Right, that would be nice. This should be synthesizable from the DebugLoc on the instruction in the asm pri...

Hi, after ignoring this for too long (see [1]), I'm still struggling how to shut down servers fed by two independent UPS systems. Both are connected to NUT via the snmp-ups driver with mibs "huawei" and "netvision". However, I fear both do not feature the LB warning via ups.status. We can shut down all less important servers (conencted to a single UPS) via upssched

I glanced over the server/ directory and was not sure where even to begin hooking this

My $0.02: LB is baked in to nut behavior. So if a UPS doesn't report LB, then it makes sense to synthesize it. Synthetic LB is the cleanest fix at the earlier processing point. One could have a config that is basically synthetic-lowbatt-percent that generates LB if (as Jim says) on battery, not calibrating, and batt% <= that. One could have a similar config

Hi, Andras, Thanks for the comments. Yes, I am aware of those issues. I probably should have been more accurate on my usage of terms. Actually in my project, the unit collection is a mixture of diphones and words. However seems to me, these synthesizer specific issue is irrelevant to my question about speex. As you said, i merely use speex as storage methods. All I ask for is to get the

Hi all, I have a question about the types of MachineOperand. There are 12 different types of MachineOperand such as MO_Register, MO_Immediate and so on. Some of the names are self-explanatory such as MO_Register and MO_Immediate. Some of them are a little confusing such as MO_FrameIndex, MO_ConstantPoolIndex and so on. For example, what is the different between MO_ExternalSymbol and
