[LLVMdev] LLVM code target dependent generator question
...alar addition. I am having hard time mapping LLVM add to my machine add instruction based on the oprand types.
Here is the sample code:
void myFunction( int* src, int* dst, int i )
{
dst[i] = src[i];
i = i + 4;
return;
}
I want to get this translate to my machine code as following:
shl R1028, R1026, 2
add_pointer R1029, R1024, R1028 // incrementing the src pointer
load R1030, R1029
add_pointer R1031, R1025,R1028 // calculating the dst address
store R1030, R1031
mov R1031, 4
add R1032, R1026, R1031 //scalar addition
ret
Currently my ADD instruction is defined in the InstrInfo.td fi...
