The "hello" string is a part of the GlobalVariable's initializer. You can use GlobalVariable::getInitializer to get a Constant with the initializer value, and then, depending on the actual type of it you can get the contents of it.

Subject: [EXT] [llvm-dev] Accessing constant contents
Hi,
I have a global variable in LLVM IR:
@mem8 = private unnamed_addr constant [9 x i8] c"Hello12\0A\00", align 1
I have loaded the module, so now have:
llvm::Value *value1;
...
value1->print(llvm::outs());
That will output:
@mem8 = private unnamed_addr constant [9 x i8] c"Hello12\0A\00", align 1
What method should I use to access the contents of the constant.
I.e. I want the "Hello12" bytes contained in @mem8 to be put in a std::vector<int8_t>
I can access the Type hierarchy, but cannot find how to access the value contents.
Kind Regards
James
