...s to helper functions that you haven't included. The main point I'd raise is: if your value is stored as a double inside the Value structure, then why are you bitcasting to i64*? Why not bitcast to double* then load and perform a proper fptosi?

Hi, I'm pursuing M.Tech course. As a part of the project work i'm using LLVM as back-end. My project area is "Enhancing the performance of V8 javascript engine using LLVM as a back-end". Now i'm writing code for shift left(SHL) operator. I had my own Value Structure .. it's like this Struct Value { void *val ; char type; } The "char type" holds

...citly back to integer representation. %7 = store bitcast i8* %dest to double*, double %6 ; Store back, reinterpreting your void* (which is i8* in LLVM) as a double*. Hopefully this makes sense, especially if you know how you would have to do it in C.

Hi Nick, I need the module.ll file. Now how can i configure LLVM to enable "c" target? Is it that i need to build from the scratch? Is there any way to enable 'c' target also?

Hi, I wanted to convert .ll file to .c file (for the sake of debugging the c file). I used the command "llc" with "-march=c" option. But i'm getting the below error. *llc: error: invalid target 'c'* * * My script file code for converting it is: llvm-as -f module.ll opt -o=module.bc module.bc llvm-dis module.bc llc -f -march=c module.bc #gcc
