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. 2016-09-26 20:12:46 +00:00			`#ifndef IRCODES_H`

Re-re-add the type inference layer, now I know more about how things work. Remove that terrible float promotion code. 2016-10-22 21:04:13 +00:00			`char returntype;`

mcgg now checks that registers have at most one type attribute set. 2018-09-03 20:03:57 +00:00			`#define burm_int_ATTR (1U<<0)`

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! 2016-10-25 21:04:20 +00:00			`#define TYPE_ATTRS \`
