David Given 83cf1be6a8 mcgg now checks that registers have at most one type attribute set. 2018-09-03 22:03:57 +02:00
David Given 9977ce841a Remove the bytes1, bytes2, bytes4, bytes8 attributes; remove the concept of a
register 'type'; now use int/float/long/double throughout to identify
registers. Lots of register allocator tweaks and table bugfixes --- we now get
through the dreading Mathlib.mod!

David Given b1a3d76d6f Re-re-add the type inference layer, now I know more about how things work.
Remove that terrible float promotion code.

David Given a0131fdb47 You know what, the type inference stuff is a complete red herring. What this
actually needs is a more intelligent register allocator. So, remove the type
inference.

David Given cc176e5183 Keep more data around about ir instructions. Implement a half-baked type
inference routine to propagate information about floats up the tree, so we know
whether to put floats into special registers as early as possible.
