2015-11-01break Tmp.phi chains at phi nodesQuentin Carbonneaux
This makes sure the Tmp.phi "chain" is at most two elements long. Something smarted could be possible, but union-find with path compression is still not exactly what I want.

2015-10-31make phi-class handling more localQuentin Carbonneaux
The phi classes are no longer in a union-find structure, instead each temporary argument of a phi node gets a pointer to it. The hinting of the phi node is then shared with its the one of its arguments. When liveness proceeds and finds out that two elements with same hinting (a phi node and one of its arguments or two arguments of the same phi node) interfere, one of them has its phi pointer reset, that way, the hinting won't be shared.

2015-09-15heavy modification of call handlingQuentin Carbonneaux
The IR generated by calls was very bulky because two instructions were used for marking the live range of a clobber. This patch attempts to store the information of what registers are use/def/clobber in the call instruction itself, this leads to more compact code (even more when we'll have SSE registers). However, I find that the amount of extra code needed is not really easonable. Fortunately it is not too invasive, thus if the complexity creeps in, it should be easy to revert.

2015-09-15start work on aggregate typesQuentin 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.

2015-09-15add a size to all operations (wip)Quentin Carbonneaux
2015-09-15add truncation operationQuentin 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.

2015-09-15tentative support for fast allocsQuentin Carbonneaux
It seems that the MEM reference type is meaningless in too many positions. Because of this, it is unclear if we should keep it or just introduce a OAddr instruction that only accepts slots. Regardless of the above, the spilling module needs to use the new slot_() function, also, the emit function needs to fetch the size of the stack frame from the slot[] array. The naming is still very transitional, here is a list of all bogus names I can think of: - SLOT() - Tmp.spill - slot_
2015-09-15major lifting: get rid of RRegQuentin Carbonneaux
I've been septic since I introduced it, this commit proves that it costs more than it helps. I've also fixed a bad bug in rega() where I alloc'ed the wrong size for internal arrays. Enums now have names so I can use them to cast in gdb to get the name corresponding to a constant.
