Hi I am wondering why the following variable has a PointerTy. @foo.data = internal addrspace(3) global float 5.000000e+000, align 4 When I do a V->getType()->dump() on the variable its printed as float addrspace(3)* thanks shrey

...galized by the second call to legalizeOp. ? My problem is that the second call asserts inside legalize ops at ResultVals[Op.getResNo()]; b'cos ResultVals has only 1 element and Op.resno is 0. I am not sure if I provided enough context. Please let me know if more information is needed. thanks shrey

...tree. I print the dominator tree and I see it is added into the tree as child of node it is supposed to dominate. How do I debug to find out why/when its getting added into the tree. ? Tips/suggestions on how to debug to find out how the densemap involved is getting updated will be great. thanks Shrey -------------- next part -------------- An HTML attachment was scrubbed...

...ion framework. While I can as part of pre regalloc pass allocate globals to registers, how can I share this information between allocation of different functions. Allocation efficiency is not as much a concern and I am ok with doing the allocation as a pre ra pass. I will appreciate any pointers ! Shrey

Hi I would like to add transformation - mostly peephole- after register allocation that make use of def-use information. Would it be possible to make use of the dag codebase to help do that ? thanks for any pointers shrey

thanks for the help ..I do add the chain and the result. My code is like this ... SDValue Ops[] = { load->getChain(), load->getOperand(1), load->getBasePtr(), des }; DAG.getNode(CustomOpc, NodeTys, Ops, 4); thanks again! shrey On Thu, Nov 12, 2009 at 4:41 PM, Anton Korobeynikov <anton at korobeynikov.info> wrote: >> My problem is that the second call asserts inside legalize ops at >> ResultVals[Op.getResNo()]; b'cos ResultVals has only 1 element and >> Op.resno is 0. > Looks like you...

hi I find machine register info carrying the lists of def use for each register - PhysRegUseDefLists[RegNo];. I dont see a lot of places using this. For instance, if this list is accurate, can this be used for def use relationships at different points? thanks shrey

...on equivalent of calling getIndex I would like to use some sort of starting slot info of a live interval in some pass. I need a way of comparing which virtual register is associated with an earlier source line without relying on any debug info. The relative order is preserved in my case. thanks shrey

...nd that the code generation would need to be non trivially modified to do this. I am wondering if it would be possible to create a map of this information and using it in a modified existing allocator. Modification would make sure the already allocated registers are not available. thanks again shrey On Thu, Jul 16, 2009 at 2:05 PM, Jeffrey Yasskin<jyasskin at google.com> wrote: > Chris recently wrote up a way to do this at > http://nondot.org/sabre/LLVMNotes/GlobalRegisterVariables.txt > > On Thu, Jul 16, 2009 at 1:53 PM, shreyas krishnan<shreyas76 at gmail.com> wrote...

thanks for the help ..I could build it with cmake generated project files Being a newbie with cmake one question, is it equivalent to configure in windows environment and so would need to be run everytime I change the source location ? thanks shrey On Wed, Oct 28, 2009 at 4:31 PM, shreyas krishnan <shreyas76 at gmail.com> wrote: > done > > http://llvm.org/bugs/show_bug.cgi?id=5331 > > shrey > On Wed, Oct 28, 2009 at 3:29 PM, Óscar Fuentes <ofv at wanadoo.es> wrote: >> shreyas krishnan <shreyas76 at gmai...

Hi Is it allowed to have registers alias within a register class ? thanks shrey

Hi I am wondering if there is way to eliminate functions that are not used after two files have been linked. Can the optimizer do it ? Or is there a way you can have it done while linking it self ? thanks for answers shrey

...o create a pointer type to a global array which is @buf = internal constant [4 x i32] zeroinitializer ; <[4 x i32]*> [#uses=0] if I just dyncast it, the element type of the resultant pointer type is not set properly. The getUnqual method gives me a double pointer. thanks for the help ! shrey

Hi I find types such as v16i32, v16f32 missing in my llvm version 2.7 So does the following page not list them http://llvm.org/docs/doxygen/html/classllvm_1_1MVT.html is that intentional for any reason or can I just add them ? thanks shrey

...em in my backend however I run into the assertion assert((unsigned)VT.SimpleTy < sizeof(LoadExtActions[0])*4 && ExtType < array_lengthof(LoadExtActions) && "Table isn't big enough!"); What does the assertion mean ? thanks for all help!! shrey On Wed, Jul 14, 2010 at 6:56 PM, Eli Friedman <eli.friedman at gmail.com> wrote: > On Wed, Jul 14, 2010 at 6:48 PM, shreyas krishnan <shreyas76 at gmail.com> wrote: >> Hi >>   I find  types such as v16i32, v16f32  missing in my llvm version 2.7 >> >> So does...

Hi I was wondering if within the TargetDescription string it was possible to specify different alignment for variables on stack versus globals. If not, is there any other way to specify that ? thanks shrey

Hi I have a question abt type information such as unsigned/signed. I find that the information is not retained in the intermediate form and if needed conversions are generated. So if I needed to generate different instructions for signed/unsigned, is that possible ? thanks shrey
