similar to: [LLVMdev] Preservance of function variables in the bytecode

Thank you, Patrick. What I want to do is just to write those source level variable names in my assembly code for a virtual machine because it is instructed in its instructions manual. I registered the VM as a target for LLC and want to emit the assembly. For this reason, I asked how to get the variables themselves which are not mangled from the bytecode. Thanks to your help, now I see they can be

Hi, I want to know the variable mapping between the source and llvm bytecode. It seems that current llvm debugging information cannot provide this mapping directly. Here is my examples (llvm 2.7). In this exmaple, I want to know the mapping: tmp<--->%4. But current llvm's debugging information can only provide that the instruction "%4 = add nsw i32 %3, 2" is at line 3 in

Hi, I want to get the mapping between C source's variables and bytecode variables. It seems that llvm doesn't provide this mapping, so I think a walk-around method is to get the instruction's mapping. I have to use llvm-gcc, not clang. Any advice? Thanks.

Eli, Thanks very much for your reply. That's what I want to know. It works for this example. But I usually have to deal with the optimized bytecode with "-O". See the example: ************** C source ************** int h (int j, int i) { int tmp; tmp = j+i+2; return tmp; } +++++++++++++++++++++++++++++++++++++ .ll file: ; ModuleID = 'simplecase.c' target

Hello, guys. I am trying to construct higher-level 'for' from the low-level LLVM bitcode(ver 1.9). It's partly successful thanks to David A. Greene's advice suggested to use Control Dependence Graph(CDG). I could find which BB contributes to form which loop with CDG. For example, for this simple function: ----------------------------------------------------------- void bsloop(int

This is the right answer for C's alloca. The question probably referred to LLVM IR's alloca, however.

Hello. My name is Seung Jae Lee. I'd like to ask you onething about converting to ARM assembly code. I saved the simplest C code shown in your LLVM webpage as 'hello.c' And I made 'hello.bc' by "$ llvm-gcc hello.c -o hello". In order to make ARM assembly code, I typed "llc -march=arm hello.bc -o hello.arm" But, I met this error. llc: ARMISelDAGToDAG.cpp:73:

Hello. Nice to meet you. My name is Seung Jae Lee, a graduate student in UIUC CEE, who is working in NCSA for the present. Nowadays I am trying to develop LLVM backend to spit out CHiMPS assembly code. In the process, I installed LLVM codes on my home directory in the host computer. But I don't think it was installed properly. While bootstrapping the LLVM C/C++ Front-End, I met several

Dear Wojciech Matyjewicz: Thank you for your advice. I could follow what you had suggested upto opt -analyze -loops bsloop-opt.bc Therefore, I could get the prints you had showed me as follows: -------------------------------------------------------- Printing analysis 'Natural Loop Construction' for function 'bsloop': Loop Containing: %bb16, %bb13, %bb8, %bb1 Loop

Hello. I am trying to run tblgen so I typed $ tblgen ARM.td -print-enums -class=Register in "llvm/lib/Target/ARM" But I got an error as follows: Included from ARM.td:18: Parsing ../Target.td:16: Could not find include file 'llvm/Intrinsics.td'! As you know, the 16th line of Target.td includes "llvm/Intrinsics.td". But this cannot find Intrinsics.td, I think. Of

Thank you for this information. If so, is there any way to grasp which kinda data throw in and out in LLVM as shown in such a way in gdb?

Hello, LLVMers. I just wonder How I can pronounce Clang. [see-laeng], [see-lang], [k-laeng], [k-lang]?? Thanks, Seung

Thank you, Bill. Seems to be better. Anyway...Is there a way I can do what you showed for me? Thanks, Seung J.

Thanks for your comment. I also tried for LLVM 2.2 but got the same compilation errors on VS2005. (I didn't modify anything before the compilation) I just wonder if I need bison and flex even just in the case of compiling them on VS2005 without changing anything because the LLVM doc says "If you plan to modify any .y or .l files, you will need to have bison and/or flex installed where

Hello, guys. I just wonder if there is any way to spit out LLVM assembly without any basic block division. E.g., If I emit LLVM assembly for the following simple code: ------------------------------------------------------------ void f_loop(long* c, long sz) { long i; for (i = 0; i < sz; i++) { long offset = i * sz; long* out = c + offset; out[i] = 0; } }

I followed the steps in "Getting Started with the LLVM System using Microsoft Visual Studio" in the document in LLVM page. I made hello.c file exactly same shown in the page. I made hello.bc on UNIX and transferred it to my Windows computer. And I typed "llc -march=c hello.bc" (Of course, I downloaded the latest version of LLVM and compiled with VS before this.) But my command

I have always built it with flex and bison installed, though I believe Chris removed our last dependence on flex a little while back, so you may not need that. I'm using bison 2.1 which I got from the getgnuwin32 folks. I imagine that if you have cygwin or the like, you probably already have everything. You will need to have the executables in your path. I build with VisualStudio 2k5

Thank you so much for your reply, Chris. If so, can I ask you two things more? First, is there any way to have various optimizations on LLVM assembly such as -O options in llvmc? llvm-gcc doesn't seem to be working for these -O options... Second, I'm still not sure about difference between *.s and *.ll. LLVM assembly *.s file can be made from llvm-gcc -S. Another assembly *.ll file comes
