...stions regarding folding operations with symbols during the instruction print stage with MC. At the moment I'm working with global symbols but i guess that other symbol types should be equivalent. My first question is how can i negate the address of a symbol? Consider this piece of code: char g_var[80]; char foo(int a) { return g_var[a]; } this gets compiles into something like (in pseudo asm): addi a, g_var load retreg, a but i dont have an add with immediate instruction so i have to do the following subi a, -g_var // negate g_var addr load retreg, a A solution I thought could be passing...

Hi all, I have a global array declared as: table = internal constant [8 x [256 x i32]] ... At the moment I'm able to get the reference to table using Constant* g_var = cast<GlobalVariable>(I.getOperand(0))->getInitializer(); ( please consider I to be a GetElementPtrInst object ). Now I would like to understand how to get the address of table[2][3], for instance, considering that I have the g_var variable. In addition, I was able to access to the valu...
