[LLVMdev] RE: Question about Global Variable
...ange Cstr to gI, it compiled successfully. Thanks again.
Another question is for constructing getelementpt.
// C code
char gStrA[10] = "test str"; // here is Global variable,gStrA and initializer "test str"
char gStrB[10]= "test str2";
main(){
int = i;
char *pGVars[20]; // here, the pGVar is for storing the address of each initializer, i.e. "test str"
pGVars[0] = gStrA;
pGVars[1] = gStrB;
// change the content of gStrA
for(i=0;i<5;i++){
pGVars[0][i] ^= 0x27;
}
}
the following IR code is the loop part code which is co...

[LLVMdev] copy value of a global's data field to another global
Hi all,
I can get access to the data stored in globals as follows:
GlobalVariable* pGvarAct=_set_a_valid_global_;
const_ptr_indicesVec=_the_indexes_
llvm::Constant* pConst;
pConst=ConstantExpr::getGetElementPtr(pGvarAct, const_ptr_indicesVec);
and e.g. use this to repalece an argumrnt of an instruction like:
I->setOperand(someArgumentIndex,pConst);
However, getGetElementPtr returns a

[LLVMdev] copy value of a global's data field to another global
getInitializer returns the complete initializer of the global.
My globals are complex nested structs, from which I want to extract e.g. one
double datafield.
Example:
>From a struct Stuct having double,array(3xint),float fields, I could extract
the second int value using the index sequence 0,1,1 with getGetElementPtr.
This gives me a constantPointer, but I would need to get a constInt...

[LLVMdev] numeric limits of llvm Types?
Hi all,
can I access the numeric limits of the llvm types,
e.g. HalfTy, FloatTy, DoubleTy, etc.
in a fashion like the std numeric_limits tool?
std::numeric_limits<half>::min()
std::numeric_limits<half>::max()
In c++API, I want to initialize values and need to know the correct range
for the llvm types....
Thx
Alex
