Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

Assumes output_addressed_constants has been done on EXP already.
Generate exactly SIZE bytes of assembler data, padding at the end
with zeros if necessary. SIZE must always be specified.
SIZE is important for structure constructors,
since trailing members may have been omitted from the constructor.
It is also important for initialization of arrays from string constants
since the full length of the string constant might not be wanted.
It is also needed for initialization of unions, where the initializer's
type is just one member, and that may not be as long as the union.
There a case in which we would fail to output exactly SIZE bytes:
for a structure constructor that wants to produce more than SIZE bytes.

Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.
