FT32 makes use of multiple address spaces.
FT32 makes use of multiple address spaces. When trying to inspect
objects in GDB, GDB was treating them as a straight "const". The cause
seems to be in GCC DWARF2 output.
This output is handled in gcc/gcc/dwarf2out.c, where modified_type_die()
checks that TYPE has qualifiers CV_QUALS. However while TYPE has
ADDR_SPACE qualifiers, the modified_type_die() explicitly discards the
ADDR_SPACE qualifiers.
This patch retains the ADDR_SPACE qualifiers as modified_type_die()
outputs the DWARF type tree. This allows the types to match, and correct
type information for the object is emitted.

* gcc/dwarf2out.c (modified_type_die): Retain ADDR_SPACE
qualifiers.
(add_type_attribute) likewise.
