similar to: [LLVMdev] Problem regarding llc command line option

Hi, I was trying to port a Target from llvm-2.6 to llvm-2.9 and have got stuck to a very strange problem. There was an option defined in the target Asm Printer file with signature as - static cl::opt<bool> AsdPri("asd-pri", cl::Hidden, cl::desc("Print ASD format")); How after compiling the target, I dont see the option enabled in $ llc -help-hidden Also it gives error

Hi Guy, Thanks a lot for the clarification. I tried using the triple for SPIR as $ clang -x cl -fno-builtin -emit-llvm -c -Xclang -triple -Xclang spir-unknown-unknown Simple_Kernel.cl However I get the following error. error: unknown target triple 'spir-unknown-unknown', please use -triple or -arch I also tried with triple nvptx-unknown-unknown clang -x cl -fno-builtin -emit-llvm -S

Hi Ankur, Since you use -Xclang, the clang executable passes multiple triples to "clang -cc1". You can see that if you add the -v option. I'm sure there is someone here who can explain it better than I... Anyhow, I think you better use clang -cc1. Make sure -cc1 is the first command line option you use. $ clang -cc1 -fno-builtin -emit-llvm-bc -triple spir-unknown-unknown

Hi, I need to find out the line no info for each lexical block in the code being compiled with llc. The docs mention metadata format for debug info for lexical block is !3 = metadata !{ i32, ;; Tag = 11 + LLVMDebugVersion (DW_TAG_lexical_block) metadata, ;; Reference to context descriptor i32, ;; Line

Hi Ahmad, Yes, merging works good. However, my problem is like this - I have a C library which consists of 1000's of functions spread through various files. The functions do not have dependency amoung each other. I want to link only relavant files( files which have functions called from my application). Since ar has a global symbol table, I believe it should be faster to look for a symol in

Hi Ankur, Why do you need archive in this case? The other way of doing this is to merge all bitcode files into single file: $ clang -c -emit-llvm abc.c -o abc.bc $ clang -c -emit-llvm bcd.c -o bcd.bc llvm-link bcd.bc abc.bc -o merged.bc Cheers, Ahmad From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of ankur deshwal Sent: 21 February 2013 17:54 To:

I guess I miss-interpreted the text in [2]. It talks about the optimizations are hindered if the compiler driver invokes link time optimizer "separately". I found that all files compiled are in bc format. Also in library archives, the embedded files were in bitcode format. So the gold linker and LLVMgold plugin are indeed working fine. However, there is still question over only 6% gain

Hi Ankur, For a MachineBasicBlock you can call getBasicBlock() to find the IR level BasicBlock from which it was generated (if there isn't a one, it will return NULL). I don't know of a way to get a finer granularity than that, though. -Jim On Jul 1, 2011, at 1:06 AM, ankur deshwal wrote: > Hi, > > Is there any way to get a pointer to the LLVM Instr from which a >

There are plans to upload, when Chandler has the time. The YouTube account is LLVMProject.

Hello everyone, Thanks a lot for the help. -target nvptx worked great with llvm-3.2. However it gives error with -target spir. LLVM/Clang trunk although works good for both options ( probably because spir is still work in progress ). Thanks again. - Ankur On Thu, Jan 24, 2013 at 12:43 PM, Benyei, Guy <guy.benyei at intel.com> wrote: > Hi Jordan,**** > > You’re right, and

The videos are OK now. Except the video of "Autovectorization with LLVM" that have a little mistake with "_" and "-" in the filenames.

Hi Nikolaos, Following commands work great for me. $ clang -S -emit-llvm -target nvptx -x cl -include clc/clctypes.h ../data-types/scalar.cl $ llc -mcpu=sm_30 scalar.s You can follow Justin's blog [1]. It helped me a lot to understand where to start. [1] http://jholewinski.org/blog/llvm-3-0-ptx-backend/ Best, Ankur On Mon, Feb 4, 2013 at 11:40 PM, Justin Holewinski < justin.holewinski

Hi, I was trying to use the following code in a if condition I->getOperand(0)->hasName() where I is an instruction with following condition already true - I->getOpcode() == Instruction::Call When I compiled a C code with llvm-2.9, I see a function call with no operand name (for operand 0) . This happens for a function with varArgs. The interesting part is that the same C code when

Hi, I tried to build an llvm archive and link it against an llvm bc file. However, it fails.

Hi, Is there any way to get a pointer to the LLVM Instr from which a particular MachineInstr is generated ? Although I understand it goes through many optimization after a LLVM instruction is converted to SDAG node, so maintaining such a mapping will be hard. Still is the mapping stored some where which can give some sane results at least in case of -O0? Thanks and regards, Ankur

Hi all, I was trying to use LTO facility of LLVM to reduce the footprint of Clang itself. I build the ld-gold  and LLVMgold.so as described at [1] and then set the environment as described too. However, had to add the path for plugin manually as Clang was not able pass it to ld automatically. Following is the setting I used before starting to build (small foot Clang. CXX=clang++ -flto
