similar to: Question about demanded bits analysis

Hi, I think canEvaluateTruncated() in InstCombiner needs use cost model to decide whether perform optimization or not. Without cost model from TargetTransformInfo, aggressively optimizing IR in vector types according to the number of bits demanded may lead to scalarization of vector operations. For example, if the input IR is: %wide.load25 = load <32 x i8>, <32 x i8>* %231, align

Hi LLVM-Devs, I have managed to complete updating our sources from LLVM v4.0 to v5.0, but I am getting selection errors for 'callseq_end'. I am aware that the 'ADJCALLSTACKUP' and 'ADJCALLSTACKDOWN' patterns have changed, and have added an additional argument to the TD descriptions for these. There are interactions with 'ISD::CALL' and 'ISD::RET_FLAG',

Hi Martin, Pseudo CALLSEQ_START was changed in r302527, commit message contains details on the changes. However CALLSEQ_END was not modified. If your made changes to ADJCALLSTACKUP to add additional argument, that may result in error. Thanks, --Serge 2017-09-15 19:09 GMT+07:00 Martin J.

Hi Serge, Thanks for your help. I have looked at the change log, and so far as I can tell, my implementation is pretty much identical to all of the in-tree targets, but I’m missing something and can’t see what it is. I have simplified my TD description to just: def MyCallseqStart : SDNode<"ISD::CALLSEQ_START", SDCallSeqStart<[SDTCisVT<0, i32>,

Hi all, hope someone can help me out with this. Background Introduction I have a data set consisting of data collected from a questionnaire that I wish to validate. I have chosen to use confirmatory factor analysis to analyse this data set. Instrument The instrument consists of 11 subscales. There is a total of 68 items in the 11 subscales. Each item is scored on an integer scale between 1 to 4.

I've got a user that wants Japanese language support in firefox... our *stock* CentOS firefox, 24.3. I've yum installed i18, and i10, and no joy. Looked at firefox addons, and there's one, 27.0. Won't install, "not compatible". Neither is either 24.0, or 25.0. Anyone have a link to a compatible version? mark

Hello devlopers, I request your guidance on how to lower the metadata attached with an instruction. Following is given the IR dump before Module verifier pass, and there is a string "Tile3" attached as metadata with instruction "%x = alloca i32, align 4, !Tile3 !1". My target is to transmit/propagate the string down to post RA-Scheduling pass. Is it possible? If yes, how

Hello, All: What would it take to make ?iconv? portable? I ask, because I want to convert accented characters to vanilla ASCII, thereby converting, e.g., ?Ra?l? to ?Raul?, and Milan Bouchet-Valet suggested on R-help that I use 'iconv(x, ?", "ASCII//TRANSLIT?)?. This worked under Windows but failed on Linux and Mac. It?s part of the ?subNonStandardCharacters? function

Hi, I''d like to have translated languate-aware routes in my application, like: /projects/5/permissions => locale "PL" /projekty/5/pozwolenia => locale "PL" Is there any way to achieve it with RESTful routes? I have done it manually with named routes, but it''s overwhelming with over 300 routes :D Also tried namespace (yeah, didn''t work) and

hi again How can i extend 5 times for effect.pulsate beats? I need that continue beat until other event client happened about my other mail, is there other solution more elegant that this? : new Effect.Pulsate(leccion[i_leccion],{duration: 5,from: 1}); thanks again rag

I would be perfectly fine with Raul & Chandler's proposal, provide that clear documentation is added. The strong distinction between standard library calls and intrinsics is an important point for front end authors. The deliberate ignorance of floating point environment flags is entirely defensible, but needs to be documented clearly. We should also document which rounding mode

Hello! clang defines some AttributeSet, for example: attributes #0 = { nounwind uwtable "less-precise-fpmad"="false" "no-frame-pointer-elim"="true" "no-frame-pointer-elim-non-leaf"="true" "no-infs-fp-math"="false" "no-nans-fp-math"="false" "unsafe-fp-math"="false"

Hi, I've recently installed the latest version of WINE (from LinuxFormat Mag), and I can run some app's (sol.exe, notepad etc). However, when I try to run 'larger' apps I run into problems. Specifically I'm trying to run MSMONEY 2001. I cd to c:/program files/microsoft money/system then run wine --winver win98 msmoney.exe and I get the following:

Hi, I need to instrument the code in order to generate an event (call a certain function) whenever X instructions have been executed. I'm using MachineFunctionPass to get machine-dependent representation of each LLVM function in the program. However, such pass doesn't allow to modify such functions. Is there any other class so I can modify MachineFunctions? Thanks in advance, Raul. --

Hello All, I would like your help to learn how to traverse an LLVM DAG and perform some analysis. I know that llc can be used to view a DAG, but I would like to manipulate them. In particular I'm interested in the instruction selection and the scheduling DAGs. I have read the documentation about writing an analysis pass and I know how to traverse a basic block on a LLVM IR assembly file, but

Hi there, I have a model with indexed fields (F1, F2, F3...). I have a field-based search (+F1:..., +F2:...), and a global search (which queries all fields with the given terms). Both of them works ok, but I would like to exclude a term from the global search (though it should remain indexed to support the field-based search), is it possible? Thanks in advance. -- Posted via
