similar to: [LLVMdev] Building for a specific target, corei7

Hi Andrew, I think I diluted my question. My question was not related to MCJIT. I ran the following 4 scenarios: (1)gcc -mcpu=corei7 tetris.c -o tetris (2)gcc -mcpu=athlon64 tetris.c -o tetris (3)clang -march=corei7 tetris.c -o tetris (4)clang -march=athlon64 tetris.c -o tetris In (1) and (2), I see difference in order of instructions in the output binaries, which I expected because every CPU

Hi Varun, I see the point of your question, but I'm not the best person to answer from that perspective. Nadav Rotem is the owner of the x86 backend, and he can probably give you a more complete answer than I could.

Hi Varun, Have you tried your experiment with icc by any chance? The MCJIT component does not assume that you will be executing the generated code on the host system because it can be used to generate code for external targets. However, you can specify the CPU by calling setCPU() on the EngineBuilder object before creating your execution engine. (You can use sys::getHostCPUName() to figure out

Noticed something I thought I would share so that others don't scratch their head wondering about it if they try the same. I updated my system to Oneiric, and decided to recompile Wine. I tried making use of the corei7 optimizations in gcc 4.6 and found that, while a lot of stuff worked (ex. Steam), other things (like DirectX games) did not. So, as always... don't expect things to work

Hi, I am first year PhD student at Stony Brook University. For one of my projects I am trying to JIT compile and run a C program containing inline assembly using MCJIT but I am not able to. I have cloned and build LLVM-3.1. Below are more details. Arch : x86 OS : Linux ubuntu 2.6.35-22-generic Sample program : test_inline_asm.c ------------------- #include <stdio.h> int main(){ int

Hi Amit, You're not doing anything wrong. This is an error in 'lli' not properly initializing the native target libraries. Fixed in SVN trunk r167392. -Jim On Nov 4, 2012, at 4:09 PM, Amit Arya <aarya at cs.stonybrook.edu> wrote: > Hi, > > I am first year PhD student at Stony Brook University.

Hi Jim, Thanks for the reply. I was able to figure out the problem in 'lli'. InitializeNativeTargetAsmParser() was missing in lli. I should have replied back saying that the problem was resolved. Hope I didn't waste your time. Regards, Amit ________________________________ From: Jim Grosbach [grosbach at apple.com] Sent: Monday, November 05, 2012 2:07 PM To: Amit Arya Cc: LLVM

And after that for all the BB you have visited more than once, you try to find a parent that has a branch instruction as a terminator. Additionally you ensure that there are no BB with branches as terminators on your way. If such

Thanks for your reply. Yes, I was about to recurse over the use list of the argument in the called function. I did not want to pursue that because with this solution, I am going to implement the interprocedural part myself and was wondering if that was not already done. I was not also 100% sure that this will work for any type of arguments. If, based on your response, this is my only solution

Hello, I have been using the USE class to access the use-def chains of different values. However, what I have noticed is that the set of users of a particular value is limited for the appearance of that variable in the current function. How can I get the interprocedural use of a particular value? For example, if a variable *a* is used as an argument in a function call *foo*, the USE analysis

Hi, I am executing a C program using JIT. When the program exits, the control comes back to my program which initiates the JIT. Now, I want to read the value(not the LLVM nomenclature) of a global variable (not the LLVM nomenclature). I am able to get the global variable, using the following command: GlobalVariable *my_global = Mod->getNamedGlobal("MY_GLOBAL"); I want to know the

Hello. I am an undergraduate student studying computer science and I am interested in working in your Open Source projects. I read about you from TeachingOpenSource.org. I am, however, new to Open Source project development thus I am seeking a mentor and an opportunity to present my skills and make valuable contributions to your projects. Thanking you. -- Varun Agrawal B.Tech-II Computer

Hi, Please excuse my ignorance, but I am just learning R (this is my very first day programming in R) and having a really hard time figuring out how to do the following: I have a matrix that is 1000 row by 6 columns (named 'table.combos') and a 1 row by 6 column vector (named 'mine'). I want to find every row in 'table.combos' that equals 'mine' and then count

Hi, A question. When I run gelman.diag and gelman.plot with mcmc lists obtained from MCMCregress, the results are following. > post.R <- MCMCregress(Size~Age+Status, data = data, burnin = 5000, mcmc = 100000, + thin = 10, verbose = FALSE, beta.start = NA, sigma2.start = NA, + b0 = 0, B0 = 0, nu = 0.001, delta = 0.001) > post1.R <- MCMCregress(Size~Age+Status, data

Hi, I got error messeges when I try to install RMySQL. The version of MySQL installed on my Debian is 4.0.12. Error messages were about the location of /include and /lib of MySQL distribution. Final error messages were; usr/bin/ld: cannot find -lz Any tips or advices? Thanks -- Sung-youn Kim -------------- Dept. of Political Science Stony Brook University (SUNY at Stony Brook) Office:

While it doesn't include all the features of the old JIT quite yet, it's complete enough to pass all of JIT's execution tests on Linux and Mac OS X (no Windows yet). As for directions on how to enable it, follow the path of the "use-mcjit" flag passed to lli

Hi Chandler, Thanks for fixing the problem with the insertps mask. Generally the new shuffle lowering looks promising, however there are some cases where the codegen is now worse causing runtime performance regressions in some of our internal codebase. You have already mentioned how the new shuffle lowering is missing some features; for example, you explicitly said that we currently lack of

Wow. Somehow, I forgot about vbroadcast and vpbroadcast. =[ Sorry about that. I'll fix those.
