RFC: Synthetic function entry counts
...profile count of call instructions based on which the hotness/coldness of callsites can be determined. Experiments have shown that using a higher threshold for hot callsites results in improved runtime performance of the generated code without significant code size increases. We propose to generate synthetic function counts for non-PGO compilation and use the counts for boosting hot callsites during inlining. Synthetic function entry counts of functions are initialized based on properties of the function such as whether it is visible outside the module, whether it has an inline keyword and so on. Then...

Synthesize low batt (LB) fron SNMP UPS which does not support 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 synthetic-lowbatt-voltage same thin...

[LLD] Writing thunks before the corresponding section
Sure. One thing I want to remind you is that there is a place in Writer.cpp where we assume all synthetic sections were appended to end of Sections list. Look for `llvm::reverse`. If you add synthetic section thunks right before/after non-synthetic sections, you also want to change that.

Passes to add/validate synthetic debug info
Hi, I've prototyped a pair of passes which 1) add synthetic debug info to a Module and 2) determine how much of that info is lost. The idea is to make it easier to write targeted test cases for debug info preservation. For example, here is a quick way to test that Mem2Reg doesn't drop debug info from one test input: > ; RUN: opt < %s -debugify -m...

[LLD] Writing thunks before the corresponding section
Hi, Sorry for delay with reply. It looks like now thunks can be implemented as a synthetic sections. In that case we give flexible solution and will be able to put thunks before/after related sections, using different alignment etc. As far as I know BFD linker uses the same approach at least for MIPS thunks. I will try to implement this idea. On Thu, Sep 8, 2016 at 1:44 AM, Rui Ueyama &...

Hello, I'm wondering if anyone has done this before and has any advice, or if anyone in general has ideas about it.

Echo cancellor causing synthetic noise..?
...ous version yet) and was wondering if anyone also has faced and solved similar difficulties. When the speex encoding/decoding (wideband) process starts, the voice is crispy clear with almost no noise in the background, but as I run it for a long time, noise start building up and even with (scary?) synthetic sounds as well. (these noises continue even when I disable mic recording thus only allowing all zero data from input device - sampling still goes on) When I only use the raw PCM data without speex codec, these symptoms didn't happen. The speex library often prints this statement to my window....

Failed Convergence when using mi to generate synthetic data
I was hoping to use mi to generate a synthetic version of a database. The strategy (see code below) was simple: use the diamonds dataset from ggplot2, subset it focus on 3K single-color, then create a blank record for every "real" record, and throw the new dataset at mi to see if it would populate the blank records. I kept getting...

Database querying for synthetic attributes?
...e database table does not. There the name is decomposed into title, firstname, lastname and possibly other adjuncts. Yes, I can think of ways to handle this generically. It could be much easier, however, to push this task into the database, for instance by defining a read-only view containing a synthetic name column made up of the individual pieces. Then, on the Rails side of things, there would have to be a way to use one table -- the view -- for find''ing records and another table for insert/update. Has anyone thought this through further or even implemented something like it? Mich...

TargetSelect.h and layering
...re a lib has other lib dependencies (whereas in the LLVM CMake build it seems libs don't depend on other libs - so every executable has to explicitly list its transitive lib dependencies) it's pretty nice to have these little libraries explicitly in the build graph - much like we have those synthetic library targets in the CMake rules, so it's easy to depend on the right/full things. (but because the CMake lib rules for LLVM don't actually describe lib dependencies, I think even 'fixing' this in upstream LLVM wouldn't make the dep situation better - the synthetic targets wo...

Request For Opinions: what to do about the synthetic statfvs "tweak"?
...his has the side effect of getting slightly different values for total and used/free space of a volume when accessed through libgfapi and when through fuse -- because these values are multiples of f_frsize, and libgfapi uses the native f_frsize of the backend (typically 4k), while fuse provides its synthetic f_frsize (typically 128k). So the libfgapi provided sizes are more granular. OTOH, I couldn't find any program in standard Unix userspace where the implementation commonly used in GNU/Linux would rely on the f_bsize hint. It does not mean there is none -- and then there is of course the vast s...

TargetSelect.h and layering

I'd mark it textual and leave it alone. Alternatively, we could make AllTargetsDescs and AllTargetsInfos and all the other synthetic libraries in CMake into real libaries and sink the bodies of these inline functions into each tiny little library. Doesn't seem quite worth it, though. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/201711...
