similar to: [LLVMdev] LLVM IR on different platforms

Hi, I am newbie for LLVM. I need some help, I want to disassemble ARM binaries and perform some operation on LLVM IR and again back to generate ARM binary from modified ARM LLVM IR. How I can proceed for the same. Any tool or document will be highly appreciated. Thanks and Regards, Deep -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, My requirement is something like as given below, a.c => a.obj contains a1() and a2() function b.c => b.obj contains b1() and b2() function main.c => main.obj call to a1, a2, b1, b2 Now, I want to move a1(), a2() from a.obj to b2.obj and on top of function b1() When I call b1() from main, it should call first a1, a2 and then function definition of b1 Can you please give me some

Hi, Yes I am looking for IR pass that will do insert call of functions that defined in another file. Links/suggestions that guide me to start for adding IR pass will help me so much.

Hi, I need some help, As per my requirement, I am trying to lower down the x86_64bit binary LLVM IR to x86 LLVM IR. Instruction of x86_64 binary are as follows, mov rax, 1122334455667788 mov rax, 8877665544332211 To lower down the same in x86, I need to split 'rax' register into 'rax_lower' and 'rax_higher'. Can anybody please give me some pointer to do the same or any

Hi, I want to call/add some functions(that defined in another file) on top of some functions, and reflect the same changes in object file. No, I am not looking for contractor.

Hi Tim, Thank you for this information. I have another request for help from you, Below is my test case, iGetValueFromASM proc mov rax, 5 mov rax, 5 mov rax, 2 mov rax, 5 mov rax, 2 mov rax, 112233445566 add rax, 2 mov rax, 112233445566 add rax, 5 add rax, 2 I have lowered 32bit LLVM IR, %0 = type { i32, i32, i32, i32, i32, i32, i32, i32, i32, i32, i32, i32, i32, i32, i32, i32, i32, i32, i32,

Hi, I need to fetch lower and higher 32bits from 64bit value. I found "CreateLShr" function to fetch lower 32bits, llvm::Value *intermediateValue = LLVMIRBuilder->CreateLShr(x64BitValue, 32); What function I need to use for fetching upper 32bits from 64bit value.

Even with your change, it was still complaining about not having a definition of MACHO_DYNAMIC_NO_PIC_P somewhere, so I took the easy way out with inserting this in arm.h: /* Overridden by arm/darwin.h, whether it is included first or not. */ #ifndef TARGET_MACHO #define

Hi All, Is this possible to generate LLVM IR from any static/dynamic link library? I have some static and dynamic link library and I want to generate LLVM IR as I want to obfuscate these libraries. Is there any way to do the same. Please give me some pointers on this. Thanks, Deep -------------- next part -------------- An HTML attachment was scrubbed... URL:

Are you saying the textual form of IR can change, but bitcode doesn't? I don't know what you mean by assembly syntax. Is there a changlog entry when the textual IR changes?

The front end I'm building for an existing interpreted language is unfortunately producing output similar to this far too often; define void @foo(i8* nocapture %dest, i8* nocapture %src, i32 %len) nounwind { %1 = tail call noalias i8* @malloc(i32 %len) nounwind tail call void @llvm.memcpy.p0i8.p0i8.i32(i8* %1, i8* %src, i32 %len, i32 1, i1 false) tail call void

I partially worked out that to do an assign I will need to manually assign a temporary first and then load data into it, which also means I'll need to set up a temporaries list in my code assembler as allocations must be done before anything else? or is it fine to allocate a variable mid-way through a function and the compiler will manage it? With that as well, if I had a function that loads

Hi guys, I am following this[1] tutorial to install clang. However, I have made a small change in the configure command, and I am running it with '--enable-optimized' option to avoid the debug build.
