Hi Amruth, If you do not specify any optimization flag for 'clang' and do not run 'opt -mem2reg' pass on the generated IR file, it is in non-SSA form. However, many variables stay in memory instead of registers in this case.

Well, it *is* in SSA form, but it "cheats" by keeping values in memory. --Sean Silva On Wed, Jun 13, 2012 at 2:00 PM, Jiesheng Wei <jwei at ece.ubc.ca> wrote: > Hi Amruth, > > If you do not specify any optimization flag for 'clang' and do not run > 'opt -mem2reg' pass on the generated IR file, it is in non-SSA form. > However, many variables stay

Does LLVM allow mapping a virtual register to a specific memory location? If not, how do we extract information on where the virtual registers are mapped to? Thanks, Amruth

Hello everyone, I didn't come across mov or copy in LLVM IR instruction set. So what is the best way to move/copy values between virtual registers?

Hello everyone, I am a newbie to LLVM and I am trying to develop an LLVM pass. I came across this page "Writing an LLVM Pass" which said, "First, configure and build LLVM. This needs to be done directly inside the LLVM source tree rather than in a separate objects directory. " where as LLVM installation page says to have a separate build directory for putting all the binaries.

Hi, This is Jiesheng Wei from UBC. Now I am working on a project with LLVM and I want to use steensgaard alias analysis tool. I saw on the website that steensgaard analysis is available for LLVM 2.9 and it is under poolalloc/ directory. I downloaded several versions but none of them is compatible with LLVM 2.9. Can you please tell me which version of poolalloc is for LLVM 2.9? Thanks, Jiesheng

Hello, I am curious to know if LLVM offers any passes to do interprocedural slicing, I need to eliminate most of the computations(possibly all, if they don't influence the control flow), but the control flow of the program should be maintained at all cost. I did see an optimization pass to print the CFG of a function without its body to a dot file, but I am interested in generating the

Hi Tim, Thank you for the quick response! so you'd probably check you're looking at a BranchInst and check BI->getSuccessor(0)->getName() (& 1 if it's conditional) I initially was printing out the result from getName() (I.getParent()->getName()) and it printed out nothing sadly. when parsing the instructions in SelectionDAGBuilder but it was only visiting instructions in

Hi, I'm becaming crazy about this! I've asked before, not no matter what i do or conf, never works. How can i make IDLE work for real with MSOutlook, so that i can receive emails when they arrive, instead of changing folder/get out and in my account? Here's my conf, should it be reflected in postconf -n (is it the running conf?): ================== root at

This doesn't really fix your problem, you just removed the signs of it. The order of the files in /etc/dovecot/conf.d matters. Please provide the following: doveconf -n grep -B2 -A1 'mail_plugins

Dear all, I have a question on how to set up the starting model in POLYCLASS and make sure the terms in the starting model retained in the final POLYCLASS model. In the function POLYMARS, this can be done using the STARTMODEL option. See below for example, I started with model y= b0 + b1*X1 + b2*X2 + b3*X4 + b4*X5 + b5*X2*X5 + e > m00 <- matrix(c( 1, NA, 0, NA, 1, 2,

Hello, Everyone, I am a student an a new learner of R and I am trying to do my homework in R. I have 10 files need to be read and process seperately. I really want to write the codes into something like "macro" to save the lines instead of repeating 10 times of similar work. The following is part of my codes and I only extracted three lines for each repeating section. data.1 <-

Hello Everyone, Would you please send me any links to documentation on LLVM stack? I am particularly interested in knowing how each instruction in an LLVM bit code file(.ll file) affects its stack. To be specific, is it possible to map an LLVM program as operations on a stack? Thanks, Amruth
