I want to add the following line to my llvm code (as specified in the ptx backend documentation):

%1 = internal addrspace(3) global [4 x i32] [ i32 0, i32 1, i32 2, i32 3 ]

However, I get the following error:

expected instruction opcode
@g = internal addrspace(3) global [4 x i32] [ i32 0, i32 1, i32 2, i32 3 ]
^

What am I doing wrong?

The line you want to add and the line on which the error is reported are not the same - I'm guessing a copy-paste error?

In any case, the first line is illegal, because you're defining a global with a local name (starting with % instead of @). The second line is legal by itself but from the error message I'm guessing you tried to write it inside a function, which is not a legal location for a global. Just like globals in C, LLVM globals need to be defined directly in the module scope, outside any function definition.

  • It was indeed a copy-paste error (I tried both and got an error for both). But the problem was indeed defining a global in function scope. Thanks! – PieterV Apr 02 '14 at 07:26
