I am interested in working on a little architecture project that involves modifying an ISA in some non-trivial ways and seeing what impact it has on instruction frequencies (and other such metrics). Clearly I'll need to hack on a compiler backend, and I thought that LLVM might be a good choice since among mature compiler infrastructures it's fairly young and presumably

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 am unable to download videos from the site http://llvm.org/devmtg/2012-04-12/.

If possible, please share the videos on other medium ( youtube etc.) too. This will spare LLVM web server from heavy traffic due to video downloads too. Thanks and

We implemented a similar solution for handling crashes in production but one issue we came across with MCJIT was that the NotifyFunctionEmitted call from the old JIT was replaced with NotifyObjectEmitted. The ObjectImage used by NotifyObjectEmitted does have a way of iterating symbols but non-external functions used in the module didn't seem to appear in this list so we were left with some

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, I tried to build an llvm archive and link it against an llvm bc file. However, it fails. Following is the procedure I followed ( abc.c is file which calls a function whose definition is present in bcd.c) $ clang -c -emit-llvm abc.c $ clang -c -emit-llvm bcd.c $ llvm-ar cr bsd.ar bcd.o $ llvm-link abc.o bsd.ar llvm-link: bsd.ar:1:2: error: expected integer !<arch> ^ llvm-link:

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

[Resending this email after subscribing to the group. Got an error message the previous time around] Hey guys, In our project we have the following workflow: - Given a user request, we construct a C++ program to service the request - We create a compiler invocation to compile that program into an IR module - We use JIT (and optionally MCJIT) to convert the IR into executable code and run it

John, thanks for that hint. It did not kill the server by you are perfectly right. I changed this and restarted the "smb" and "nmb" deamons - unfortunately with the same result. When I watch e.g. the status with "swat" I see as follows after trying with: smbclient -U <user> -L win2k1 (what is strange since I connect as different user and not

Hi Andy, In the NotifyObjectEmitted method of our derived JITEventListener class we use the begin_symbol() iterator to walk the object's symbols looking for functions and only functions marked with ExternalLinkage seem to show up. I'm not sure how I would access the Dwarf info from within there, is there a way? Thanks, Andrew On Wed, Nov 13, 2013 at 8:23 PM, Kaylor, Andrew

Thanks for the info. I am using old JIT. So that should not be a problem. I will take a look at using oprofile. I have never used it - so will be somewhat of a learning curve. I notice that the configure script has a --with-oprofile option. In addition to enabling that, is there something else that also needs to be done? My copy of LLVM is compiled with --enable-optimized. Will --with-oprofile

I have joined my win2k client machines (win2k professional or win2k professional server) to my PDC. This worked fine and I did all recommended as e.g. in the HOWTO http://hr.uoregon.edu/davidrl/samba/samba-pdc.html#joining. So far I can also login localy to the win2k client machines using a local account and connect a network drive from the PDC using a valid account on the PDC (as given in the

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

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

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:
