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. Thanks, Jiesheng On Wed, Jun 13, 2012 at 1:17 PM, <amruth.rd at knights.ucf.edu> wrote: > I am experimenting with LLVM optimizer and found that

I am experimenting with LLVM optimizer and found that the bit code file clang emits is already in SSA form, but I want to generate it in non-SSA form. Would you let me know if there is any way of doing it? Cheera,Amruth -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

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

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 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

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

We are working on a new front-end for LLVM IR for a low level language; The input has mov from one scalar to another and we would like to represent these in LLVM IR. being new to LLVM I am not sure if there is a way to represent this since I couldnt find a mov instr. Thanks -------------- next part -------------- An HTML attachment was scrubbed... URL:

The input language is at assembly level, and the location akin to a %temp ( a virtual register if you will) and contains moves from one virtual to another. Though these are not like memory but I could represent them as local variables and do loads and stores; so I dont know how to represent it in C except as local variables.

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

Do you know how to do the action you seek in C? If yes,

you can use an add with zero, if you dont think you are adding redundancy.

Dear all, The architecture I am working with supports moving values directly from one register to another, or moving an immediate straight to a register, and I cannot figure out how to do this in LLVM. I originally tried matching something like [(set RegisterClass:$dest, RegisterClass:$src)] in my TargetInstrInfo.td: def MOVrr : MyInstrClass<(outs CPURegs:$dest), (ins CPURegs:$src),

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,
