That's because instructions have a location associated with them, not a compile unit. -eric On Thu, Oct 4, 2012 at 12:46 PM, George Baah <georgebaah at gmail.com> wrote: > I used DILocation instead of DICompileUnit and it works.

Here is the code. I am running on llvm 3.1 on Lion (Mac 10.7.4) *string getFileDirectory*(*const* Instruction &I){ MDNode *MD = I.getMetadata("dbg"); DICompileUnit compileUnit(MD); return compileUnit.getDirectory().str(); } George On Wed, Oct 3, 2012 at 12:40 PM, Eric Christopher <echristo at gmail.com>wrote: > Without knowing the code that you've written

Hmmm, but it has a getDirectory function. -G On Thu, Oct 4, 2012 at 3:50 PM, Eric Christopher <echristo at gmail.com> wrote: > That's because instructions have a location associated with them, not > a compile unit. > > -eric > > On Thu, Oct 4, 2012 at 12:46 PM, George Baah <georgebaah at gmail.com> wrote: > > I used DILocation instead of DICompileUnit and

You should probably think of the DIFooBar constructors like reinterpret-casts, not "go find the thing I actually want" functions. If you hand DICompileUnit() a node that is not a compile-unit metadata node, it's not going to tell you that you goofed. If you _did_ have a CU metadata node, then DICompileUnit's getDirectory() would work just fine. But you don't. --paulr

I used DILocation instead of DICompileUnit and it works. Hmmm, interesting. George On Thu, Oct 4, 2012 at 1:33 AM, George Baah <georgebaah at gmail.com> wrote: > Here is the code.

Yeah, It looks like I am doing exactly what's in Dwarf*.cpp files, yet I am getting blanks.

I mean an llvm Pass that transforms switch statements into if statements. For example, if I have code with switch statements then running the pass will convert all switches to ifs in the bytecode.

Without knowing the code that you've written and the IR that you're running on I'm not sure what I can do to help you. -eric On Wed, Oct 3, 2012 at 9:32 AM, George Baah <georgebaah at gmail.com> wrote: > Yeah, It looks like I am doing exactly what's in Dwarf*.cpp files, yet I am > getting blanks. > > George > > On Tue, Oct 2, 2012 at 2:10 PM, Eric

Hi Folks, Is a java frontend still being developed for llvm? George -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20120726/95b28fc7/attachment.html>

There is also the LowerSwitch pass that converts switch instructions to a sequence of branches.

Hi, I'm investigating a bug which I have so far been able to narrow down to the following small testcase: ======== test.c =========== int *get_pntr(int *p) { return p; } __attribute__((noinline)) void store(int *p) { int *p2 = get_pntr(p); *p2 = 10; } int test() { int i; store(&i); return i; } ----------------------------- If this is compiled in two steps as

Hi Guys, I am using the Postdom pass and I would like to get the root of the tree. However, everytime I try to get the root, I get a segfault. I don't know why the environment can't find DominatorTreeBase. Below is the code that generates the Segfault. In my .h file I include Dominators.h PDT.getRootNode(); //PDT is a reference to a PostDominatorTree dyld: lazy symbol binding

Thank you very much guys, I really appreciate your help.

I did M.getOrInsertFunction and called the exit function with . IRBuilder<> builder = IRBuilder<>(...); Value *one = ConstantInt::get(Type::getInt32Ty(M.getContext()),1); builder.CreateCall(exitF,one,"tmp4"); "Instruction has a name, but provides a void value! %tmp4 = call void @exit(i32 1) Broken module found, compilation aborted!

Hi All, Is there a pass in llvm that converts switch statements to if statements? George -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20130506/f06741c4/attachment.html>

Hi Everyone, I have an llvm project from which I am trying to call external libraries such as boost. For some reason, when I type make, llvm can't seem to find the header files to the library even though it's in the path. I am baffled by this. For example, for boost this is what I get: " fatal error: 'boost/lambda/lambda.hpp' file not found" Do I have to modify

Hi All, I am new to LLVM. I am trying to get the Hello example in "lib/Transform/Hello" to run. But when I do a make in the directory I get this error. I don't understand why it can't find these make files. ../../../Makefile.common:60: ../../../Makefile.config: No such file or directory ../../../Makefile.common:68: /Makefile.rules: No such file or directory Should i make

Hi Everyone, I am trying to insert an exit function into my IR. However, I thought I can get access to exit by using Module.getOrInsertFunction or Module.getFunction. However, I am getting a null value returned. I have searched through the llvmdev archives but not found any thing that addresses this question. Any help will be greatly appreciated. Thanks.
