2015-09-17 | start work on fuction parameters | Quentin Carbonneaux | |
2015-09-15 | heavy modification of call handling | Quentin 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. | |||
2015-09-15 | emit stack fixup only when necessary | Quentin Carbonneaux | |
2015-09-15 | reshuffle instructions around call | 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 | fix alignment for structs on the stack | Quentin Carbonneaux | |
2015-09-15 | diagnose float structs | 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 | get rid of OTrunc | Quentin Carbonneaux | |
2015-09-15 | the wide bit of OAddr matters! | Quentin Carbonneaux | |
2015-09-15 | add a size to all operations (wip) | Quentin Carbonneaux | |
2015-09-15 | alloc16 comes for free, iiuc the abi | 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 | the abi is unclear, practice suggests that change | Quentin Carbonneaux | |
2015-09-15 | OXTestw should not have 64bits arguments | Quentin Carbonneaux | |
2015-09-15 | new NAlign constant and fix frame size computation | Quentin Carbonneaux | |
2015-09-15 | move spill and emit to the new slot system | Quentin Carbonneaux | |
In emit, I worked a little to make sure that framesz works when we change the size of the svec array (if we need more alignments). | |||
2015-09-15 | add sign/zero extension operations | Quentin Carbonneaux | |
2015-09-15 | add the mul instruction | Quentin Carbonneaux | |
2015-09-15 | make sure tests emitted are encodable | Quentin Carbonneaux | |
2015-09-15 | replace RMem refs with an OAddr opertation | Quentin Carbonneaux | |
2015-09-15 | compile branches on and using test | Quentin Carbonneaux | |
2015-09-15 | make sure eflags-writing do not disappear | Quentin Carbonneaux | |
This is a hack implementation, ideally I would like something cleaner. The problem is that regalloc thinks an instruction is dead code because it's not aware that it writes to eflags. | |||
2015-09-15 | handle OAnd in isel | Quentin Carbonneaux | |
2015-09-15 | change strategy for phi nodes | Quentin Carbonneaux | |
2015-09-15 | tentative support for fast allocs | Quentin 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_ | |||
2015-09-15 | major lifting: get rid of RReg | Quentin 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. |
