2015-10-08	emit alignment directives properly	Quentin Carbonneaux

2015-10-07	finish implementing data parsing	Quentin Carbonneaux

2015-10-01	support negative frame offsets in emit	Quentin Carbonneaux
	They are used to access function parameters passed on the stack.
2015-09-30	uniformize alignment code in framesz()	Quentin Carbonneaux

2015-09-29	wip on new stack slots (emit, spill)	Quentin Carbonneaux

2015-09-22	parse return types of functions	Quentin Carbonneaux

2015-09-21	emit syntactically valid calls	Quentin Carbonneaux

2015-09-20	factor formatting inside emitf	Quentin Carbonneaux

2015-09-20	simplify two loops with a pointer	Quentin Carbonneaux

2015-09-20	save callee-save registers	Quentin Carbonneaux

2015-09-17	add hack in emit to support stack arguments	Quentin Carbonneaux
	The number stored in the .val field of SLOTs has to be sign extended, so we can reach into the caller's frame when necessary (arguments passed on the stack).
2015-09-17	start work on fuction parameters	Quentin Carbonneaux

2015-09-15	hack to enable proper regalloc on calls	Quentin Carbonneaux
	I add the dual to dummy uses: dummy defs. They are compiled to nothing, but help preserving the invariants I had when writing the register allocator. Clearly, there should be a better way.
2015-09-15	implement aggregate passing in regs	Quentin Carbonneaux

2015-09-15	start function call lowering (wip)	Quentin Carbonneaux

2015-09-15	start work on aggregate types	Quentin Carbonneaux
	The parser now has some code to parse the description of structured types. I tried to be even less specific than LLVM "type" by creating just enough abstraction so that I can deal with both AARCH64 and x64. The base types used in the definition of an aggregate are really just syntactic sugar to give a structure a size and an alignment. Only the location of float components matters for the compilation. In particular this means that the front-ends have to know how the ABI works to pass/return small integer types. This also means that the font-end has to be aware of the layout of structures. Chris Lattner has a proposition [1] for LLVM that is still pending and goes in the direction of giving more control of the ABI the front-end.

2015-09-15	split some long calls	Quentin Carbonneaux

2015-09-15	fix two bugs in new emit	Quentin Carbonneaux

2015-09-15	update emit to the new setting	Quentin Carbonneaux

2015-09-15	fix invalid test in emit	Quentin Carbonneaux
	It could be that the destination of the copy is a spill location, so we have to check the type of i.to first.
2015-09-15	output labels only when necessary	Quentin Carbonneaux

2015-09-15	change cmp $0, %reg, to test %reg, %reg	Quentin Carbonneaux

2015-09-15	fix emit(OCopy) and use pointers in max.ssa	Quentin Carbonneaux

2015-09-15	remove non-critical diagnostics	Quentin Carbonneaux

2015-09-15	add truncation operation	Quentin Carbonneaux
	It would be nicer to have some kind of subtyping where a l variable can be used in place of a w variable but it is more complications than a truncation insutruction. In some cases, it might be less efficient than the above solution by requiring two registers instead of one. (I.e when both the truncated variable and the long variable live together.) We have to see what are the usage patterns.
2015-09-15	new NAlign constant and fix frame size computation	Quentin Carbonneaux
