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! Bin -------------- next part -------------- An HTML attachment...

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 w...

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

...arning. Looking at clients/upsmon.c I think, without the flag ST_LOWBATT set for ups->status, MINSUPPLY will never truly be considered a usable threshold and thus I'm left with a machine which would not shutdown. Thus, what would e the best way forward here? * Try to patch the server to synthesize LB there? If so, any suggestion how to do this? * Try to patch upsmon.c's is_ups_critical method to also include extra criteria, e.g. remaining run time/battery charge? * Keep nut unpatched but use our own NOTIFYCMD or CMDSCRIPT to pull the values from the server and implement our logic th...

I glanced over the server/ directory and was not sure where even to begin hooking this in. Should this be directly in upsd (upsd.c) or rather in/near th...

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 synthetic-lowbatt-volt...

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 samples as close to original recording as possible after encoding and decoding. Blending, cross fading, pitch adjustment, these signal processing issues...

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
