similar to: [LLVMdev] LowerDbgDeclare results in redeclaration of local variable

There was a patch committed the other day that should, at least, work around some of the behavior you describe. Optimized debug info is an area that's being worked on in ToT and previous releases are particularly bad. I'd use that. -eric On Mon, Apr 29, 2013 at 7:02 AM, Pankaj Gode <godepankaj at yahoo.com> wrote: > Hi All, > > Due to 'LowerDbgDeclare' call ( as

Hi Eric,   Thanks for patch information. I have checked the patch with my code and I see that it works. But when I extract the variable and check the metadata information to retrieve the scope information, I do not get exact scope, after optimization. As you said that this is a work in progress, so can we expect full version on this in llvm3.3 release ?   Regards, Pankaj

Hi,   The link and the information shared was helpful.   I will make my problem definition more clear. While I am "asm printing" target code, I also want to emit scope related information. Scope related information includes, - for each scope, start line, end line, start column, end column and - scope heirarchy. As scope is delimited by "{" and "}" (for an input

Hi All,   int global; int func( int t) {    //scope 1   {      ....   } <-----   return x; }   For the above code, i want to collect endline (indicated by <---) for the scope.

Pankaj, If you want to decorate MachineInstrs then for the end of scope you're not looking at "}" but instead you're looking at _last_ machine instruction in that scope. Now, if you want to find out start and end MachineInstrs for a lexical scope (and corresponding line numbers) then see CodeGen/LexicalScopes pass. It collects lexical scope information and maps MIs to respective

Hi All,   Can we extract name of variable name from "MDNode" ?   1. Neither temp_MDNode->getName() nor temp_MDNode->getValueName() give me "global_int" which is name of a variable.   2. I tried below ways as well. DIVariable DV(mdnode1); Value *v = mdnode1->getOperand(0);//gives add 0x69   3. I have written below code to reach till variable name.        LLVMIname is

Hi All, I was checking for GIT or SVN versions corresponding to llvm3.1 release by checking svn and git logs, but failed to find the exact match. I checked with r156747, which is the last version it shows in      http://llvm.org/svn/llvm-project/llvm/tags/RELEASE_31/ but when I 'diff' this with the 'downloaded llvm3.1 release'(http://llvm.org/releases/download.html#3.1), then I

In order to detect whether CallSite is present in innermost loop, do I need to insert logic from LoopInfo pass for collecting loops, within a CallGraphSCC pass?   Is there any other approach for this?   Regards, Pankaj -------------- next part -------------- An HTML attachment was scrubbed...

Closing this, found below links to get variable name.   http://groups.google.com/group/llvm-dev/browse_thread/thread/1a239f0d24db2b5c   http://markmail.org/message/fj5qg44vyjsdde7k#query:+page:1+mid:5zhmyncisenomcga+state:results           I could do following, to get the required information.                 const CallInst *CI = dyn_cast<CallInst>(Insn);                 int numoperands =

Hi All,   While collecting type information for "anonymous types", I had below observation.   For the example with anonymous types, given below struct test {   struct {     union {       Char a[4];     };   };   struct {     int b;     char c;   }; };   LLVM 2.6 defines the types as %struct.anon1 = type { %union.anon0} %struct.anon2 = type { i32, i8} %struct.test = type {

In addition to the link below, please check for functions like "llvm.debug.declare", "llvm.debug.value", as you will not get LoopInfo for these.   Pankaj   ________________________________ From: Devang Patel <dpatel at apple.com> To: Ryan Taylor <ryta1203 at gmail.com> Cc: llvmdev at cs.uiuc.edu Sent: Wednesday, November 30, 2011 11:08 PM Subject: Re: [LLVMdev]

Dear All, I am following a flow to generate object files(.o) from input (.s assembly) files. The input .s is given to AsmParser, which creates MCInst after matching instruction opcode. These MCInst are converted to MCStream and then finally emitting to an object file using Target Code Emitter. I am considering whether hazard recognition can be done on the list of MCInst, which I get after

Thanks for the info. Curious, do you know if there is an opt that will put all loops, including nested ones, in functions (ie each loop in it's own function)? What I'm trying to do is create a way for each loop to have only one exit. I want all loops to be single exit loops? I can write my own pass but I'd rather not. I think that if I can put each loop into it's own function
