similar to: [LLVMdev] Disabling certain optimizations in llvm-gcc and llc

Hi all, A few different though somewhat related questions here. I'm really grateful for your answers! 1. From a previous question I know that sizeof's are resolved into literals early in the front-end before IR is even emitted. It seems that they are resolved into whatever value is correct for the host machine. But if one wishes to then take the IR and emit assembly code for some other

The "target > datalayout" information is purely a hint to the optimizers. My experience this far has been mainly with using llvm-gcc and llvmc,

No. This won't work since, as indicated in the FAQ entry IR derived from C/C++ is not target neutral, so you cannot 'just'

Dear LLVM community. I have a function pass. This pass will insert a llvm intrinsic function prototype (llvm.memset.p0i8.i32) to the module at the doInitialize stage. Then at runOnFunction Stage, this pass will find the insert points and insert calls of this intrinsic function. However, when the -O2 flag is turned on, the strip unused function optimization will automatically delete this

Hello list, I've been working on a package of my own. It works fine on the 32bit linux machines that I've tested it on. Someone using 64bit ubuntu wanted to try it, and surprising segfaults happened. My test code results in no segfault, errors, or leaks from my calls when run under valgrind (I recompiled R with the level 2 valgrind instruments). R and packages are compiled from source,

Hi folks, please check out our RFC: Supported Optimizations attribute https://docs.google.com/document/d/1s0n-JVaSNML1Z9SCZVg2bgisxswIJAK2Tp9DahucW10/edit?usp=sharing Pasting it here for the record: RFC: supported_optimizations attribute Piotr Padlewski - piotr.padlewski at gmail.com Krzysztof Pszeniczny - kpszeniczny at google.com December 2018 Introduction Sometimes a possible class of

Dear Sanjoy Das and community. I was tried to fix a bug in the pass InitAllocas from SAFECode. This is a function pass and will insert a prototype of 'llvm.memset.p0i8.i32' in the module at doInitialize() stage of the pass. But, this prototype will be eliminated by strip unused function optimization since there is no call on this function after doInitialization(). Therefore there will be

Hi all, I was wondering if there's any way to pass command line arguments to LLVM optimization passes when run through the opt tool. For example, suppose I register called MyPass, then I want to run opt -load libMyPass.so -MyPass 3 < input.bc and have "3" be available to MyPass as a kind of argv argumnet through some method. Or does it take a major rewrite of the opt tool

A follow-up question: Is there a way to make different passes accept one command line option that will affect all of them? For example, I'd like to have a -optStrength parameter, that can be given to all of my passes simultaneously.

Hi Harel, Several existing passes can take command line arguments. Have a look at lib/Transforms/Scalar/LoopUnrollPass.cpp for example. Its command line arguments are defined using the cl::opt objects.

Hi all, When using "make check" with the DejaGNU test collection, I encounter two unexpected failures (they seem to be closely related). My question: are they well known, and if so what's the problem and how can I fix it? This is the error text I get: FAIL: /var/data/common/trunk/llvm/test/FrontendC/2008-05-19-AlwaysInline.c Failed with exit(1) at line 1 while running:

Hi all, I couldn't find any reasonable way to create the IntegerType that would match, say, intptr_t, that is the native word size of the machine I'm building on. More accurately defined, when compiling on a 64 bit Mac OS machine I want it to be Int64Ty, but if for example I'm using the "-arch i386" command line option on that machine during compilation, I want it to be

Hi All, I?m trying to do ?things? after my Dial application terminates (e.g. play IVR to called party, calling party, etc.). I?m trying to use the local channel for this purpose but so far with no success. I?m using 1.6.1.18 and this is my extensions.conf: [Internal] exten => _22,1,Dial(Local/${EXTEN}@CW/n) ; 22 is test number exten => _22,2,Noop(After Hangup) [CW] exten =>

Thanks, but I'm not sure I understand. I see no such flag in clang 2.9 nor couldn't I find any mention of it. What does it do?

Is there a similar mechanism anywhere for clang?

Hi All, I would like to separate the media traffic from the signalling. Can Asterisk send and receive media (rtp) traffic from a secondary network interface?

You could make the cl:opt object visible outside one of your passes, and use it in your other passes : in other words, it is a global variable shared between several files.

Hi all, I've been subscribed to this list on-and-off and always found it very helpful. I'm facing the problem of compiling a project in Objective C with LLVM in a Darwin environment. There is a certain Objective C protocol that appears in two .m files, and so the corresponding l_OBJC_PROTOCOL and l_OBJC_LABEL_PROTOCOL symbols appear in both .o files. The problem is that while these

Hello, I have a question regarding incoming fax to local file (on the Asterisk server). While the fax is received properly (I have the tiff file generated as expected) I get the warning 'FAX CNG detected but no fax extension' on the consol. If the fax is received ok then what 'fax extension' does it expect and what should I do there? My Setup: Sender -> Public PSTN ->
