Hi all,
This is a simple patch to correct the comment for ADDR_EXPR tree code.
The resulting expression of ADDR_EXPR is a tree with POINTER_TYPE.
So the result mode should ptr_mode instead of Pmode.
As far as I understand, Pmode is the addressing mode. But not the mode to
represent a pointer (or address?).
Okay to commit?
Regards,
Renlin
