A user found that gdb would not correctly print a field from an Ada
record using the scalar storage order feature. We tracked this down
to a combination of problems.
First, GCC did not emit DW_AT_endianity on the enumeration type.
DWARF does not specify this, but it is an obvious and harmless
extension. This was fixed in GCC recently:
https://gcc.gnu.org/pipermail/gcc-patches/2024-January/642347.html
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=5d8b60effc7268448a94fbbbad923ab6871252cd
Second, GDB did not handle this attribute on enumeration types. This
patch makes this change and adds a test case that will pass with the
patched GCC.
So far, the GCC patch isn't on the gcc-13 branch; but if it ever goes
in, the test case in this patch can be updated to reflect that.
