>Description:
The function rtl_for_decl_location only handles constants
and memory references if it is called "before reload is completed".
If a global variable is in a fixed register, i.e.:
register int *current asm ("r2");
then debug information is emitted for it without any DW_AT_location tag. This is because reload_completed is cleared at the end of rest_of_compilation.
Should dwarf2out_global_decl be setting another flag
for this code to check?
