[LLVMdev] InsertElementInst and ExtractElementInst
...om a vector I seems that it does not work.
This is the part of my IR:
%"ins or1" = insertelement <3 x i32> undef, i32 %38, i32 0
%"ins and2" = insertelement <3 x i32> undef, i32 %41, i32 1
%"ins xor3" = insertelement <3 x i32> undef, i32 %43, i32 2
%extract4 = extractelement <3 x i32> undef, i32 %35
...
store i32 %extract4, i32* %46, align 4
The output of my program is different that the expected one, like the
extractelement takes an undefined value.
The instructions I used are:
Instruction *Insert0 = InsertElementInst::Create(vector, Or_set,...
