The Module-level symbol table contains types, global variables and
functions.

You can try it out on the demo page:

... but the answer to your question is that the C front-end transforms
them into global variables.  Thus, the constant string "Hello world\n"
turns into the LLVM global:

%.str_1 = internal constant [13 x sbyte] c"Hello world\0A\00"

File static variables are handled similarly,
